I tried to install ejabberd in my local Mac OS X machine, but while configuring sqlite using following command as mentioned in steps. I'm stuck at the following issue.
./configure --prefix=$HOME/my-ejabberd --enable-sqlite
Error received
checking for SQLite3 library >= 3.6.19... yes
cat: /include/sqlite3.h: No such file or directory
./configure: line 4172: test: !=: unary operator expected
configure: WARNING: Cannot find SQLITE_VERSION macro in sqlite3.h header to retrieve SQLite version!
configure: error: SQLite3 library >= 3.6.19 was not found
Steps I followed from - https://docs.ejabberd.im/developer/install-osx/
If you just want to install vanilla Ejabberd then you can simply do brew install ejabberd.
According to the issue, you can also try:
./configure --prefix=$HOME/my-ejabberd --enable-sqlite --with-sqlite3=/usr/local/opt/sqlite
P.S. I have filed the issue on Github Ejabberd.
i'am using a Windows x64, i need to use Mysql 8 in QT 5.14.2( MinGW x64)
i've started installing MySQl driver as indicated :
2- then when, I am using:
cd $QTDIR/qtbase/src/plugins/sqldrivers/mysql
3- and run:
qmake -- MYSQL_INCDIR="C:\Program Files\MySQL\MySQL Server 8.0\include" "MYSQL_LIBDIR="C:\Program Files\MySQL\MySQL Server 8.0\lib"
I'm getting :
Project ERROR: Library 'mysql' is not defined.
in the log file it shows me that there's a missing file sybfront.h anyone knows how to solve this please
You should replace '\' by '/', either paths will be invalid, even on Windows.
And one quote " is not closed in your code.
qmake parameters follows the same rules as pro file contents:

I am looking for an advisable version of JRuby that supports OpenJDK-8 (Zulu-JDK) to run on a Rails project.
Rails version- 4.0.13.
All versions of JRuby since version 9.2.0.0 will run on JDK 8. Since Zulu 8 is a build of OpenJDK 8 that means any appropriate JRuby version will run on Zulu 8.
Follow up question (using answer section to get better code formatting then commenting on the answer above).
I'm trying to get JRuby > 9.2.0.0 running Zulu 8 for MacOS ARM 64-bit (M1 chip).
I did a reinstall of the JRuby versions after installing that JDK.

RMySQL library works at R-64bit version.
but still it doesn't work with the 32bit R version
because I'm using statconn tools(DCOM, rcom) which only work with the 32 version R,
I need to access MySQL DB with R-32bit Version.
below are thing i've done till now.
install latest Rtools
install 64-bit MySQL Client( 32bit version doens't work)
C:\Program Files\R\R-2.12.1\etc\Renviron.site and add line like MYSQL_HOME=C:/mysql (path to your mysql files)
copy libmysql.lib to (mysql/lib/opt, R_HOME\bin, windows\system32)
install.packages('RMySQL',type='source')
set R_HOME, MYSQL_HOME to enviroment variables properly
add R_HOME, MYSQL_HOME, Rtools to path.
error messages :
RS-MySQL.o:RS-MySQL.c:(.text+0x2f23): undefined reference to `mysql_get_client_version#0'
RS-MySQL.o:RS-MySQL.c:(.text+0x2f44): undefined reference to `mysql_get_client_info#0'

how can i use 32bit R version with 64bit MySQL?
For your information.
"RODBC" library works with 64 bit R version, but 32 bit R version
Trying to install RMySQL on 64-bit Windows 7.
Using R-2.14.2 with Rtools214 and MySQL Server 5.5.
Read through several step-by-steps of RMySQL source installation.
Troubleshooting:
- Copied libmysql.dll to R-2.14.2/bin AND R-2.14.2/bin/i386.
- Copied libmysql.dll and libmysql.lib to MySQL Server 5.5\lib\opt.
- Entered MYSQL_HOME=C:\Program Files\MySQL\MySQL Server 5.5 into Renviron.site, saved to R\R-2.14.2\etc.
My instances of common problems:
Sys.getenv('MySQL_HOME')
[1] "C:\Program Files\MySQL\MySQL Server 5.5\"
install.packages('RMySQL', type = 'source')
Installing package(s) ...
...
RS-DBI.c:1:0: sorry, unimplemented: 64-bit mode not compiled in
make: [RS-DBI.o] Error 1*
ERROR: compilation failed for package 'RMySQL'
...
I'm guessing my problem lies in the '64-bit mode...' message, but I'm not sure.
Thoughts?
I'm not sure this error message has anything to do with RMySQL, or any particular package.
On 64bit Windows, instead of the default PATH :
C:\Rtools\MinGW\bin
( gives the error sorry, unimplemented: 64-bit mode not compiled in )
you might (quite reasonably) notice the MinGW64 directory alongside and try :
C:\Rtools\MinGW64\bin
but in fact it needs to be :
C:\Rtools\gcc-4.6.3\bin
Then of course, stop and start a new DOS window to pick up the new PATH.
I had problems installing RMySQl
so I installed the package RODBC which works fine.
(make sure the MySQL driver is installed).
