The libmysqlclient functions themselves are unresolved

[apatterno]

I admit I'm a newbie to the C backend for MySQL. Anyway, here's my problem: I wrote a simple program to test the client library, but every mysql_* symbol is reported as unresolved.

Also, I might add, I am POSITIVE that libmysqlclient.a exists in /usr/local/mysql/lib.

#include <mysql.h>
#include <stdio.h>

int main ()
{
  char *mysqlClientInfo;

  mysqlClientInfo = mysql_get_client_info();
  if (mysqlClientInfo != NULL) {
    printf(&quot;%s&quot;,mysqlClientInfo);
    return 0;
  }
  return 1;
}

And I compiled with this command:

$ gcc -I/usr/local/mysql/include -L/usr/local/mysql/lib -lmysqlclient simplemysqltest.c
simplemysqltest.c: In function `main':
simplemysqltest.c:8: warning: assignment discards qualifiers from pointer target type
/tmp/ccVTW7ra.o: In function `main':
/tmp/ccVTW7ra.o(.text+0x7): undefined reference to `mysql_get_client_info'
collect2: ld returned 1 exit status

Is there something obvious I'm doing wrong?
I'm using MySQL 4.0.13 and gcc 2.95.3.

Please help, thanks in advance.

I am sorry; I made a foolish mistake. But for the benefit of the rest of the forum, here's the problem:

I put my command line arguments in the wrong order. I also didn't link with zlib (didn't realize you had to.)

Here's the correct compile command:

[tt]$ gcc -I/usr/local/mysql/include simplemysqltest.c -L/usr/local/mysql/lib -lmysqlclient -lz -o simplemysqltest[/tt]

This was actually the first time I ever tried to invoke gcc from the command line... usually I just leave things up to GNU automake And my background's in MS Windows anyway. Eeeek.

_{I REALLY hope that helps.}
