MonoDevelop ValaBinding install failed - monodevelop

I installed monodevelop in ubuntu 13.04 from git with the help of README.md, but I received an error
checking for LIBVALA... no
configure: error: Package requirements (libvala-0.12 >= 0.12) were not met:
No package 'libvala-0.12' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables LIBVALA_CFLAGS
and LIBVALA_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
I have installed libvala-0.20-0 and libvala-0.20-dev by apt-get.
I have googled for this question and found some links,but helpless.
my mono was at version 3.6.1.
THX FOR HELP.
update 2014-06-19
I found the config.log file and see the error
configure:4075: checking for LIBVALA
configure:4084: $PKG_CONFIG --exists --print-errors "libvala-0.12 >= $LIBVALA_REQUIRED_VERSION"
Package libvala-0.12 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libvala-0.12.pc'
to the PKG_CONFIG_PATH environment variable
Although I have installed libvala-0.20-0 and libvala-0.20-dev, I doesn't own a libvala-0.**.pc file.
What can I do the next?
I have resolved thest problem by finding a libvala-0.12.pc file :)

While the Vala language, valac, and most of the bindings distributed with Vala are meant to be API stable, libvala is not. libvala-0.20 provides a very different API/ABI from libvala-0.12, and apparently MonoDevelop's Vala plugin hasn't been updated since Vala 0.12.
If you don't want the Vala plugin, I'm sure MonoDevelop provides a way to disable it (probably passing --disable-vala or something similar to ./configure). If you need the Vala plugin, though, you'll have to install libvala-0.12 or update the plugin to use a newer version of libvala.

now the problem is solved.
I used cn.archive.ubuntu.com/ubuntu for my apt-get.
These's no libvala-**.pc file in the package.
So whatever version I installed by apt-get, I can not get a libvala-*.pc file.
I searched in google for libvala-12.0.pc and changed my source to cz.archive.ubuntu.com/ubuntu, then I got that file.
Now I can run my monodevelop with valabinding.
Thx for #nemequ , I didn't use a higher libvala, so I don't know if it will be different when using a libvala-hight-than-12.0.pc file.
Hope these is usefull for others.
If you don't want to install vavabind after configure once ,just use ./configure --select, it's written in README. My bad :(

What exactly needs to be included in a RubyMine custom Ruby configuration, esp. for debugging?

I usually use rvm, but also need to work with a custom Ruby build. I understand that when I go to the RubyMine "Settings", "Languages & Frameworks", "Ruby SDK and Gems" dialog, I need to press "+" and select "New Local with Custom Configurator".
On that dialog, the Ruby interpreter path is self explanatory, but I don't know which environment variables I need to specify in the "Custom Configurator" session. What information needs to go there?
I am using RubyMine 2021.1 on both Mac OS and Linux. I need to be able to debug, which means that when RubyMine installs the debug support gems, they need to go to the right location, and be found from that location.
It turned out that all I needed to specify there was my GEM_HOME:
env GEM_HOME=/opt/my-custom-ruby/gems/2.7.0
I was surprised that I didn't also need to explicitly set the path to the directory containing the Ruby interpreter (for commands other than ruby, such as bundle), but I guess RubyMine does that for me. Or, maybe it doesn't, and I just haven't encountered an error yet.
Edit: It turns out I did have an issue with a gem not being found. I added to that env command and the problem went away, but I'm not really sure yet if that was the issue or if adding both GEM_PATH and PATH were necessary. Here is what I wound up with:
env GEM_HOME=/opt/my-custom-ruby/gems/2.7.0 GEM_PATH=/opt/my-custom-ruby/gems/2.7.0 PATH=/opt/my-custom-ruby/bin/ruby:$PATH
EDIT 2021-12-24
I just tried this again on a new installation and the above did not work. I was getting build errors saying that I needed to install the development tools. It turned out that when specifying the path in the
Custom Configurator field I needed to include the path for the gcc compiler. I just put most of the paths in my login PATH value there, and the gem installation succeeded.

"Fatal error: 'EXTERN.h' file not found" while installing Perl modules

While trying to install Perl modules like JSON::XS or YAML::XS, i receive the same error:
XS.xs:1:10: fatal error: 'EXTERN.h' file not found
I use MacBook, xCode is up to date, everything else that could help is up to date too.
Since OS X El Capitan, Apple introduced System Integrity Protection which restricts writing to /usr/lib /usr/bin and other sensitive directories (even to root or sudo user) that are used by the installation of Perl bundled with the Operating System. This can cause issues when it comes to installing new modules and also if trying to install XS modules ( those linked to external C libraries ).
For this reason you should not consider the default Perl installation as a working development environment, especially if you are installing custom modules.
Check out this thread on PM and others. I had since El-Capitan managed to solve this before by manually building from tarball and adding a few params or environment variables to set the paths believing that it would be best to retain use of the system Perl but this is not the way to go. This makes your environment difficult to build but also brittle and sensitive to OS updates that may either break things in many different ways.
The best practice seems to be starting with a Perl using brew install perl and work in this environment, remembering to setup your bash_profile as directed by the installer.
Also worth remembering to do a brew link perl. If you receive warnings about this clobbering what looks like system Perl libraries don't worry - these are likely modules that were installed by you over the top and it will cause you less trouble to link over these. If you have concerns, make a note of which module installs will be cleared and re-install them once your environment is configured ( ie your module installer approach is configured using cpanm or sticking with the old perl -MCPAN -e shell etc)
This new Perl setup from brew eliminates the need to continuing running sudo which adds another layer of things that can go wrong as environment variables don't follow through and permission conflicts arise etc.
Finally to simplify package/module installation I suggest doing a brew install cpanminus. If you had previously already installed this, you can ensure the paths etc are configured by doing a brew reinstall cpanminus
If you want to take it another step further then you can install perlbrew as well which will give you the ability to run multiple versions of Perl as your user and configure these with their own libs and modules which can be very useful particularly if aligning with your production environment for testing etc.
One problem you may face if moving from system Perl to this kind of approach is needing to deal with any hangovers from installing things with sudo. It wis worth taking a little time to get all this set up right though and your issues going forward will be greatly reduced and you won't be left with that nagging feeling that you don't want to change anything for fear of it all breaking.
I have also come across a Perl Blog Article that suggests a fix for XS issues with perlbrew on Mojave
This Gist described updating your cpan shell install root though this shouldn't be necessary unless your cpan is stuck in an old config after taking steps above.
I've also raised this as a new issue on PerlMonks
After reading https://developer.apple.com/documentation/xcode_release_notes/xcode_10_release_notes#3035624 and installing the Additional headers via
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
I successfully compiled without the missing 'EXTERN.h' error
In order to follow the common advice I also tried with Perlbrew to install a dedicated development version of Perl. Especially with the advice in mind First, do not use the system Perl on MacOS. The installed version is for Apple, not for you (see the discussion here: https://www.perlmonks.org/?node_id=1224727).
Unfortunately, the following error occurred:
Test Summary Report
-------------------
porting/libperl.t (Wstat: 65280 Tests: 35 Failed: 0)
Non-zero exit status: 255
Parse errors: No plan found in TAP output

Result: FAIL
make: *** [test_harness] Error 1
##### Brew Failed #####
Therefore, I decided to install it the following way (and not following the advice due to the error).
Even after having the above mentioned macOS SDK headers already installed on Catalina (macOS 10.15.2) it didn't work for me. I faced the issue during the installation of the Perl module Mac-SystemDirectory-0.13. The following steps (by identifying the missing file in hope of having a more generic approach for more or less equivalent issues) did the trick:
Locate the header file (in this case EXTERN.h)
sudo find /Library -type f -name EXTERN.h
/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Perl/5.18/darwin-thread-multi-2level/CORE/EXTERN.h
/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/System/Library/Perl/5.28/darwin-thread-multi-2level/CORE/EXTERN.h
/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/System/Library/Perl/5.18/darwin-thread-multi-2level/CORE/EXTERN.h
Ensure the installed Perl version (here 5.18) match the header file:
perl -v | grep version
This is perl 5, version 18, subversion 4 (v5.18.4) built for darwin-thread-multi-2level
Export the path for the C-Compiler (note MacOSX10.15.sdk for Catalina and Perl Version 5.18)
export CPATH=/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/System/Library/Perl/5.18/darwin-thread-multi-2level/CORE
Invoke the Makefile.PL with perl
perl Makefile.PL
BTW — For anybody who's still struggling with this, my workaround was:
bash% module="Sub::Util" # For example
bash% cpanm --configure-args="INC=-I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Perl/5.18/darwin-thread-multi-2level/CORE" "$module"
Please try this
CPATH=$(dirname $(find /usr/local/Cellar/ -name EXTERN.h)) cpan JSON::XS
For Big Sur and perl 5.30, EXTERN.h is at /Library/Developer/CommandLineTools/SDKs/MacOSX11.3.sdk/System/Library/Perl/5.30/darwin-thread-multi-2level/CORE
I'm trying to upgrade CPAN itself and got that error. But I have /usr/bin/cpan and I can't write there so I have to tweak it to write the updated version to /usr/local/bin/cpan.
No promises, but yum install perl-devel worked for me.
As #huyz has helpfully pointed out, if you hit this error on a Mac, you don't have this option, even though this is probably your issue, and you need to follow one of the above methods of getting a version of Perl that isn't missing important chunks, as per other answers.
But if, dear reader, you hit this error on a linux host, as I did, then this might be an option for you.
Building on what E Lisse suggested, you might also have luck looking in
/System/Volumes/Data/Library/Developer/CommandLineTools/SDKs/
For example:
CPATH=$(dirname $(find /System/Volumes/Data/Library/Developer/CommandLineTools/SDKs/ -name EXTERN.h)) cpan JSON::XS
You could also find where EXTERN.h is located and add that to your shell by default, e.g. in your .bashrc or .zshrc file:
export CPATH=/System/Volumes/Data/Library/Developer/CommandLineTools/SDKs/MacOSX12.sdk/System/Library/Perl/5.18/darwin-thread-multi-2level/CORE/

Upgraded to MediaWiki 26 alpha, missing Assert

I try to upgrade to the newest alpha due some testing of extensions. But I get this error, and after Googling some time, I haven't been able to find it.
Fatal error: Class 'Wikimedia\Assert\Assert' not found in /var/www/MediaWiki/includes/libs/ProcessCacheLRU.php on line 132
Since WikiMedia 1.25, some modules were extracted out of the core to vendor directory, including the assert module. To plug these, add the following line:
require_once "vendor/autoload.php";
When installing from Git, you may need to clone another repository.
I had forgot to run
composer update
I can extend this answer by saying you are running this in the prompt in the root directory of your installation. Read more on https://getcomposer.org/

Geant4 does not find Expat library

I'm trying to install Geant4 10.00 on Linux Mint 15. I have the unzipped geant4 file geant4.10.00.p01 in the directory I made:
/home/mickmau5/Geant4
along with the required build file geant4.10.00-build.
This site goes throught the installation process http://goo.gl/nzxpQG . I'm at the lengthy cmake command part and getting this error
mickmau5#linuxmint ~/Geant4/geant4.10.00-build $ cmake -DCMAKE_INSTALL_PREFIX=/home/mickmau5/Geant4/geant4.10.00.p01-install /home/mickmau5/Geant4/geant4.10.00.p01

Seems like I ought to download some things.
Thanks for any help!
From the Geant4 documentation:
GEANT4_USE_SYSTEM_EXPAT (DEFAULT : ON)
If set to ON, build Geant4 with an external install of Expat. In this
case, the Expat headers and library will be searched for under the
standard system paths. If these are not sufficient to locate the
required Expat installation, see the Advanced EXPAT_INCLUDE_DIR and
EXPAT_LIBRARY options.
Whilst Expat is installed on the vast majority of systems, it may be
missing in certain instances. In these cases, simply switch this
option to OFF and Geant4 will build and use its internal version of
Expat.
REQUIRES : Expat library and headers.
I had the same problem and I could fix it by downloading the expat-devel library.
To install expat-devel package (dnf package manager):
dnf install expat-devel

Mysql Plug-in for Qt

I've installed recent Qt (4.5.3) sdk windows version. I'm want to use mysql in my app. Since Qt Mysql plugin in not available, so I compiled it from the included source. I copied compiled files D:\\Qt\2009.01\qt\plugins\sqldrivers.
Now when I run my application it still error "QMYSQL driver not loaded".
I suggest you take the whole Qt4 source code and compile it specifically for your own needs.
Something like this should do the job just fine:
Download the Qt source code from qt.nokia.com
Extract it somehwere and open a command prompt.
"cd" into the source directory and run "configure":
Just an example:
/Devel/qt/configure
-release
-fast
-opensource
-nomake "demos examples"
-silent
-qt-sql-mysql
You might have to additionally provide -I C:\path\to\mysql\includes and -L C:\path\to\mysql\libs.
After that, do "make install".
Hope that helps.
There may be several reasons leading to the driver not being loaded, I experienced several of them in my Qt experience.
Qt provides good documentation on this point, I suggest you have a look at the Troubleshooting subsection of Qt Assistant's SQL Database drivers section, it should help you diagnose your problem. It worked for me.
Hope that helps.
After compiling the plugin, you need to add the MySQL bin path to your PATH environment variable.
