Re: Problem compiling with MySql support

Dear Stipe,

conftest.c:
--
#line 4467 "configure"
#include "confdefs.h"
/* Override any gcc2 internal prototype to avoid an error.  */
/* We use char because int might match the return type of a gcc2
    builtin and then its argument prototype would still apply.  */
char mysql_init();

int main() {
mysql_init()
; return 0; }
--

First I ran a flat compile:

]# gcc conftest.c
/tmp/ccyfJ0bD.o(.text+0x11): In function `main':
: undefined reference to `mysql_init'
collect2: ld returned 1 exit status

(Silly me) I wasn't specifying the right libraries and paths. Then I've
tried running it as config.log showed (I removed the redirector "1>&5" to
get any output on the console).

gcc -o
nftest  -D_XOPEN_SOURCE=600 -D_BSD_SOURCE -I/usr/include/libxml2   -rdynamic
conftest.c -lmysqlclient  -L'/usr/lib/mysql' -lmysqlclient -lz -lcrypt -lnsl
 -lm  -lresolv -lnsl -lm  -lpthread -L/usr/lib -lxml2 -lz -lm

And it compiled perfectly. I then ran ./conftest and it executed and
returned without complaining about anything (nor displaying anything).

Just for kicks, I've run ldd to find out the linkage:

]# ldd conftest
        libmysqlclient.so.10 => /usr/lib/mysql/libmysqlclient.so.10
(0x4001e000)
        libz.so.1 => /usr/lib/libz.so.1 (0x40056000)
        libcrypt.so.1 => /lib/libcrypt.so.1 (0x40064000)
        libnsl.so.1 => /lib/libnsl.so.1 (0x40091000)
        libm.so.6 => /lib/tls/libm.so.6 (0x400a6000)
        libresolv.so.2 => /lib/libresolv.so.2 (0x400c8000)
        libpthread.so.0 => /lib/tls/libpthread.so.0 (0x400da000)
        libxml2.so.2 => /usr/lib/libxml2.so.2 (0x400e9000)
        libc.so.6 => /lib/tls/libc.so.6 (0x42000000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

I am also including my gcc/ld versions, just in case:

]# gcc -v

Configured with:
../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info

]# ld -v
