Hello list I have a problem debugging a program that uses MySQL. The program itself does not have problems, it runs perfectly when run in the console (command prompt), but if it is executed inside the Visual C++ 2008 debugger it causes an error:
Unhandled exception at 0x004b1560 in MyProgram.exe: 0xC0000005: Access violation reading location 0x00000000 when it reaches mysql_real_connect() I'm using "mysql-6.0.8-alpha-win32" binary with setup.exe installer. Note that I don't try to enter inside mysql functions, even if no breakpoints are setup and I let the program to run freely it aborts there with the unhandled exception. My VC++ 2008 configuration is this: ------------------------------------------------------------------------ Includes: C:\Program Files\MySQL\MySQL Server 6.0\include Libraries: C:\Program Files\MySQL\MySQL Server 6.0\lib\debug Code generation: Multi-threaded /MT Precompiled headers: NO Aditional dependencies: wsock32.lib mysqlclient.lib libmysql.lib mysys.lib Ignore specific library: (as found in a forum post) LIBCMTD.lib Debugging: YES /DEBUG ------------------------------------------------------------------------ I based my configuration on this post for VC++ 6.0 http://forums.mysql.com/read.php?45,49606,49606#msg-49606 I guess it may be due to the ignored LIBCMTD.lib (debug version of MT?), but if don't ignore it the compilation fails at link time with lots of redefined symbols. My concrete question: is there something wrong with the configuration shown in that post that I adapted to VC++ 2008? are VC++ programs with MySQL unable to run inside VC++ debugger? I don't want to debut my MySQL code it is working already for *NIX, but there are other parts of the program that may require debug and it aborts when calling a mysql function. Thanks for any comment or help
