I have compiled a program in fedora using the mysql dev library (include mysql.h in header file). I need to compile in on FreeBSD. I do not want to download from source and compile but rather would like to download from ports or something equivalent to facilitate removing it if need be.
Does anyone know the equivalent of the libmysql-dev in FreeBSD. I have not found it in ports?
You do not need a special package for this. The standard mysql client package/port already includes the libraries and the header files you will need. The header files will end up, by
default, in /usr/local/include/mysql/ directory, while
the libraries will go to /usr/local/lib/mysql/.
So - just install a client from ports or packages, and you are set.
mysql.h is included in the mysql-client-xx port.
assuming you have a configure script or makefile you should set the LDFLAGS and CPPFLAGS environment variables to:
export LDFLAGS='-l /usr/local/lib'
export CPPFLAGS='-I /usr/local/include'
(or setenv, if using csh)
then ./configure and make as normal.
if you are compiling from the command line "gcc -o myprog mysource.c" just add the -I and -l options to your command and it should compile fine.
try: find /usr/local -iname 'mysql' to see files (headers, shared objects and binaries) you in fact have installed on your system.

I'm building DBI and DBD::mysql in a continuous integration build server. The build of DBI is successful, as seen in the excerpt of the build log below. It clearly installs DBI/DBD.pm in the correct location.
pushd DBI-1.643
perl Makefile.PL INSTALL_BASE=/data/pods/mysql-tools/mysql-tools/current
...
Installing /data/pods/mysql-tools/mysql-tools/current/lib/perl5/x86_64-linux-thread-multi/DBI/DBD.pm
...
Appending installation info to /data/pods/mysql-tools/mysql-tools/current/lib/perl5/x86_64-linux-thread-multi/perllocal.pod
But the next part of the build for DBD::mysql fails because it can't find the files installed by DBI.
pushd DBD-mysql-4.050
perl Makefile.PL INSTALL_BASE=/data/pods/mysql-tools/mysql-tools/current --ssl
Can't locate DBI/DBD.pm in #INC (#INC contains:
/usr/local/lib64/perl5
/usr/local/share/perl5
/usr/lib64/perl5/vendor_perl
/usr/share/perl5/vendor_perl
/usr/lib64/perl5
/usr/share/perl5 .)
at Makefile.PL line 15.
You can see, MakeMaker for DBD::mysql isn't adding the install location to its #INC at all. It just has default directories.
Is there a way to pass an argument to MakeMaker to add the install directory to #INC? I suppose I could hard-code it, but that seems improper and hard to maintain. Is there a better way to automatically add INSTALL_BASE/lib/perl5/<arch> to #INC?
Environment:
CentOS 7 Linux
Perl 5.16.3
I would have preferred to use cpanm of course. But the CI build server is isolated from the internet because of my employer's security policy. No http proxying is allowed from CI.
According to the documentation, INSTALL_BASE is used for telling make install where to put the installed module:
INSTALL_BASE
INSTALL_BASE can be passed into Makefile.PL to change where your
module will be installed. INSTALL_BASE is more like what everyone else
calls "prefix" than PREFIX is.
but it does not tell perl where to look for installed modules. To do that you can use the environment variable PERL5LIB, according to the documentation :
PERL5LIB
A list of directories in which to look for Perl library files before
looking in the standard library. Any architecture-specific and
version-specific directories, such as version/archname/, version/, or
archname/ under the specified locations are automatically included if
they exist, with this lookup done at interpreter startup time. In
addition, any directories matching the entries in
$Config{inc_version_list} are added.
I copied the commands (from these instructions: http://www.shogun-toolbox.org/install#ubuntu) into the terminal and they seem to have worked, but there is no documentation on how to make Octave find the libraries. I have tried modshogun and init_shogun but Octave cannot find them. I do have the libraries in usr/lib, and I have put that directory on PATH. I have even set usr/lib as my working directory in Octave and that did not help. As far as I have found, there is no Shogun documentation on what to do at this point.
I have also tried compiling Shogun from source, but configure couldn't find GCC. Apparently, this is a known problem with newer versions of GCC. I decided to ask for help with the former method because at least I have the libraries with that.
Edit: I am following the instructions here http://www.shogun-toolbox.org/install#manual-basics
When i do cd build and then "cmake -DINTERFACE_OCTAVE=ON" it tells me there is no cmakelists.txt. There is one in in the above folder, but when I go to that directory and do "cmake -DINTERFACE_OCTAVE=ON" again, it tells me "Shogun can only be built with GPL codes if the source files are in /home/derose/shogun/src/shogun/src/gpl. Please download or disable with LICENSE_GPL_SHOGUN=OFF."
However, when I add -LICENSE_GPL_SHOGUN=OFF as an option, i get the error "CMake Error: The source directory "/home/derose/shogun/src/shogun/-LICENSE_GPL_SHOGUN=OFF" does not exist."
You've linked to the Ubuntu install instructions. From there
These currently do contain the C++ library and Python bindings..
No word that this would include the GNU Octave binding. See below on the same page:
The native C++ interface is always included. The cmake options for building interfaces are -DINTERFACE_PYTHON=ON -DINTERFACE_R .. etc. For example, replace the cmake step above by cmake -DINTERFACE_PYTHON=ON...
So you have to grab the source and fire up cmake with something like -DINTERFACE_OCTAVE=ON
Steps to build the bleeding edge of shogun (the github repo) and the Octave interface:
git clone https://github.com/shogun-toolbox/shogun && cd shogun
git submodule update --init
mkdir build && cd build
cmake .. -DINTERFACE_OCTAVE=ON
make -j4
I have some C code that #includes the file <mysql/mysql.h>. I am running on a Mac, and cannot figure out how to get mysql installed (after running the solution found on SO, the mysql directory does not even exist in the system library). I was able to download MySQL from the source code, and now I have a mysql.h file-- in the "include" directory of the source code.
However, moving this file into the system library alone will obviously not make my program work. I expect that I need to compile the library (which I've done), and to move the binary file somewhere, in order to be linkable to my program.
As per #RustyX's suggestion, I installed the Mac MySQL package. That put a copy of mysql.h into the /usr/local/mysql-5.7.19-macos10.12-x86_64/include/ directory. However:
1) I am using gcc to compile the .c file. I am not sure how to configure gcc to include the directory in question. I tried
-L(directory path)-- both for the installed Mac MySQL package, and the MySQL source code I downloaded-- but I get the following error:
ld: library not found for -lmysqlclient
Is there another path I would include for mysqlclient? Or another package to install?
2) Even if I do include it, it will still not find the file since the called-for filename is <mysql/mysql.h>, and the filename it will find is <include/mysql.h>. Since the file is used by others, is the best course of action here to rename the include directory to mysql? Or to change the path in the .c file, and then change it back every time before committing?
Have you tried a statement like this,
#include <mysql.h> //in your program
To compile and run
gcc -w -c -g -I/usr/include/mysql filename.c
gcc -o filename filename.o -L/usr/lib64/mysql -lmysqlclient
./filename (input params)
I just came across a weird situation after installing cuda... I literally followed every single step suggested by the nvidia website: http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/#axzz3H0tm46yY.... everything seems to be fine, even the samples work... however when I try to run the "hello world" program presented in Cuda by Example documentation, the terminal displays:
The program 'nvcc' is currently not installed. You can install it by typing:
sudo apt-get install nvidia-cuda-toolkit
This is quite strange since nvcc should already be installed during the procedure suggested by the nvidia website....
Does anyone have any idea?
The PATH variable needs to include your cuda /bin directory (by default it is /usr/local/cuda-6.5/bin)
On Ubuntu you can edit the .bashrc file on your $HOME directory, adding the following;
export PATH=/usr/local/cuda-6.5/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-6.5/lib64:$LD_LIBRARY_PATH
If you are running a 32-bit Ubuntu version, then the paths are:
export PATH=/usr/local/cuda-6.5/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-6.5/lib:$LD_LIBRARY_PATH
After editing the bashrc file, source it (or simply restart the terminal):
source ~/.bashrc
Of course, if you have changed the default location of your CUDA directory you must change the PATHS accordingly.
PLUS: there are another options to tell the system where to find a library, a program, etc. like using enviromental modules, specify the complete path to the libraries and programs manually are another options. There are many methods out there!
Developing locally in MAMP and need Sphinx to work with MAMP's MySQL. Basically hitting a dead end during $ sudo make.
MAMP installs without some necessary resources for Sphinx integration, mainly a mysql lib directory and an include directory filled with C header source files. These were downloaded and installed successfully (using CMake) into the following directories:
/Applications/MAMP/Library/include/mysql
/Applications/MAMP/Library/lib/mysql
After unzipping Sphinx and running:
sudo ./configure --prefix=/usr/local/sphinx --with-libstemmer --with-mysql=/Applications/MAMP/Library
I got:
******************************************************************************
ERROR: cannot find MySQL include files.
Check that you do have MySQL include files installed.
The package name is typically 'mysql-devel'.
If include files are installed on your system, but you are still getting
this message, you should do one of the following:
1) either specify includes location explicitly, using --with-mysql-includes;
2) or specify MySQL installation root location explicitly, using --with-mysql;
3) or make sure that the path to 'mysql_config' program is listed in
Changing the ./configure command to:
sudo ./configure --prefix=/usr/local/sphinx--with-libstemmer --with-mysql-includes /Applications/MAMP/Library/include --with-mysql-libs /Applications/MAMP/Library/lib
throws the following on the outset, but regardless results in a successful configuration:
configure: WARNING: you should use --build, --host, --target
configure: WARNING: invalid host type: /Applications/MAMP/Library/include
configure: WARNING: you should use --build, --host, --target
configure: WARNING: invalid host type: /Applications/MAMP/Library/lib
The log also has the following line, (which I think is relevant in a sec):
checking MySQL include files... -Iyes
Now, continuing, $ sudo make throws the following:
Making all in src
/bin/sh svnxrev.sh ..
make all-am
g++ -DHAVE_CONFIG_H -I. -I../config -DSYSCONFDIR="\"/usr/local/sphinx--with-libstemmer/etc\"" -DDATADIR="\"/usr/local/sphinx--with-libstemmer/var/data\"" -I/usr/local/include -Iyes -Wall -g -D_FILE_OFFSET_BITS=64 -O3 -DNDEBUG -MT sphinx.o -MD -MP -MF .deps/sphinx.Tpo -c -o sphinx.o sphinx.cpp
In file included from sphinx.cpp:16:
sphinx.h:64:19: error: mysql.h: No such file or directory
... //whole bunch of errors follow, resulting from the above
So, I know mysql.h exists in my includes file, I think I have all necessary binaries as well, and the configuration seems to see the include files so I'm tearing out my hair a bit. I'm hoping this is a simple path problem, or a syntax error on my part with the ./configure attribute since this is my first time compiling and installing from the command line.
Thanks.
Sphinx's ./configure uses an unknown default value for --with-mysql, which is enabled by default, which could make you think calling it is not necessary.
To get Sphinx to work with MAMP's varyingly distributed MySQL files, make sure to use each of the following attributes in your ./configure command, specifying direct paths for each:
--with-mysql= // root mysql app
--with-includes= // path to mysql header includes
--with-mysql-libs= // path to libmysqlclient.dylib files
The final command that worked for me:
./configure --prefix=/usr/local/sphinx --with-libstemmer --with-mysql=/Applications/MAMP/Library --with-mysql-includes=/Applications/MAMP/Library/include/mysql --with-mysql-libs=/Applications/MAMP/Library/lib/mysql
--prefix is your preferred install directory in usr/local and --libstemmer adds Snowball's extended stemming functionality (if you downloaded it).
If this runs without error, just make and make install and you're good to go.
Also note that there's a configure error log in the uncompressed Sphinx directory that's easy to overlook. Didn't help in this scenario, but could be really useful to others if you're having problems.
