-DMYSQL_CLIENT_NO_THREADS and undefined reference to `my_pthread_fastmutex_init'

[GVLePage]

Binary package hint: libmysqlclient-dev

This is a known mysql bug
     http://bugs.mysql.com/bug.php?id=43397

Installing the source for libmysqlclient-dev yields
    mysql-dfsg-5.1 in mysql-dfsg-5.1-5.1.41

The error generated when compiling/linking against
     -lmysqlclient
     -I/usr/include/mysql -DBIG_JOINS=1 -fno-strict-aliasing -DUNIV_LINUX -DUNIV_LINUX (as per mysql_config --cflags using ${shell mysql_config --cflags} in my make file)

Using
     -DMYSQL_CLIENT_NO_THREADS
     solves the issue but is not really a satisfactory solution in my opinion

Without using
      -DMYSQL_CLIENT_NO_THREADS
      this error gets generated

          dus.o: In function `g7::dus::initialize()':
          dus.cpp:(.text+0x12d): undefined reference to `my_pthread_fastmutex_init'
          collect2: ld returned 1 exit status
          make: *** [all] Error 1

Will this be patched in a future package of
     libmysqlclient-dev

I built a very light weight C++ wrapper around the mysql c api, mostly so I do not have to pass mysql parameters around, members of the class I built maintain those the values I need internally, the application is multithreaded.

Thanks and regards,
G

Thanks for the pointer. I have linked the upstream bug against this one, and changed this to Triaged/Medium

Hello, our apologies for not getting back to you sooner on this. We took a look at the upstream bug from the MySQL developers and see this has been addressed. As this version of mysql/ubuntu are no longer supported, the supported versions should contain this fix, so we will proceed to close this out. Thank you!
