Can"t static link to mysqlclient on RH7 or 9
Can"t static link to mysqlclient on RH7 or 9
am 20.06.2003 14:58:57 von Olaf van der Spek
Hi,
I hope this is the right list to send this to because I think this is a bug
in the static mysqlclient lib.
I want to compile and static link this code, but as you can see it doesn't
work.
I've tried this on multiple systems. libmysqlclient.a exists.
# cat mysql_test.cpp
#include
int main()
{
MYSQL h;
mysql_init(&h);
return 0;
}
# g++ -lmysqlclient mysql_test.cpp
# g++ -lmysqlclient -static mysql_test.cpp
/tmp/ccwpQvKN.o(.text+0x1e): In function `main':
: undefined reference to `mysql_init'
collect2: ld returned 1 exit status

Examine output of:
mysql_config
on your server(s)
Here is example from my RedHat9 where I have compiled 3.23, 4.0, 4.1 and 5.0 and
I'm able to link statically against each of them.
mysql_config
Usage: /usr/local/bin/mysql_config [OPTIONS]
Options:
--cflags [-I'/usr/local/mysql-4.0/include/mysql']
--libs [-L'/usr/local/mysql-4.0/lib/mysql' -lmysqlclient -lz
-lcrypt -lnsl -lm]
--socket [/tmp/mysql.sock]
--port [3306]
--version [4.0.14]
--libmysqld-libs [ -L'/usr/local/mysql-4.0/lib/mysql' -lmysqld -lpthread
-lz -lcrypt -lnsl -lm -lpthread -lrt]
You need to add all -L and -I flags in order to link against your MySQL libraries
Best regards

Your link command is wrong. -l goes after command option, which you do
not have at all.

Wouldn't the compiler complain about missing files if it couldn't find them?
