to access MySQL

hello, all,

  i have very simple C++ program, which is to be used to create a connection with MySQL (V4.0) server. In this short program only few MySQL APIs are called, such as "mysql_init(...)", "mysql_real_connect(...)". of course, the header file was included "mysql.h".
  This  program had been successfully compiled, however, when it is to be linked to an exe file, a few errors were thrown out ( the error info is following ) , is the command wrong , or do any other header files have to be included in source?
  Operating system is RedHat !

[root@hw userproject]# gcc -I../include Test.o ../lib/libmysqlclient.a -o test
Test.o(.eh_frame+0x11): undefined reference to `__gxx_personality_v0'
../lib/libmysqlclient.a(my_compress.o)(.text+0xb4): In function `my_compress_alloc':
: undefined reference to `compress'
../lib/libmysqlclient.a(my_compress.o)(.text+0x12a): In function `my_uncompress':
: undefined reference to `uncompress'
collect2: ld returned 1 exit status

  thanx in advance

Do you have any files in /usr/lib/mysql path? Also, check if you have installed mysql-devel package for your distro.

hello, gtkfreak,

 i found a solution, it looks like,

[root@hw userproject]# gcc -o Test Test.cpp  -I../include Test.o -L../lib -lmysqlclient -lz,
however, i hav no idea about the option "-lz"? any idea?


No. I use Anjuta IDE for C programming and in there, I can add the libraries to the make file. This makes it more easy to manage large software projects. Anjuta is available at

To find what -lz stands for, you can try $ man gcc on the command line on your system.
