I am attempting to interface between a simple C program and MySQL client library, but without luck.
I searched the MySQLforum archives to see if there was info specific to this problem. While there were other folks who had problems connecting C/C++ to MySQL, none of the issue were similar to this, that is linking to resolve external name table references. Here is the actual program: ******* myprog.cc *********** #include </usr/include/mysql/mysql.h> int main(void) { MYSQL * myptr; mysql_init(myptr); return 0; } To compile it, I use: $ gcc -c myprog.cc To link/load: $ ld myprog.o -o myprog ld: warning: cannot find entry symbol _start; defaulting to 08048074 myprog.o: In function `main': myprog.o(.text+0xd): undefined reference to `mysql_init I tried the following (with this result): $ ld -lmysqlclient -o myprog myprog.o ld: warning: cannot find entry symbol _start; defaulting to 08048208 /usr/lib/libmysqlclient.so: undefined reference to [EMAIL PROTECTED]' Or, if I compile and link/load in one step, I get this: $ gcc -o myprog myprog.cc /tmp/ccJ8uuvK.o: In function `main': /tmp/ccJ8uuvK.o(.text+0xd): undefined reference to `mysql_init' collect2: ld returned 1 exit status And "ls -l /usr/lib/libmysqlclient*" reveals: rwxrwxrwx 1 root root 24 Mar 13 19:34 /usr/lib/libmysqlclient.so -> libmysqlclient.so.12.0.0 lrwxrwxrwx 1 root root 24 Mar 13 19:34 /usr/lib/libmysqlclient.so.10 -> libmysqlclient.so.10.0.0 -rwxr-xr-x 1 root root 224606 Feb 13 04:25 /usr/lib/libmysqlclient.so.10.0.0 lrwxrwxrwx 1 root root 24 Mar 13 19:34 /usr/lib/libmysqlclient.so.12 -> libmysqlclient.so.12.0.0 -rwxr-xr-x 1 root root 249972 Feb 13 04:25 /usr/lib/libmysqlclient.so.12.0.0 lrwxrwxrwx 1 root root 26 Mar 13 19:34 /usr/lib/libmysqlclient_r.so -> libmysqlclient_r.so.12.0.0 lrwxrwxrwx 1 root root 26 Mar 13 19:34 /usr/lib/libmysqlclient_r.so.10 -> libmysqlclient_r.so.10.0.0 -rwxr-xr-x 1 root root 230560 Feb 13 04:25 /usr/lib/libmysqlclient_r.so.10.0.0 lrwxrwxrwx 1 root root 26 Mar 13 19:34 /usr/lib/libmysqlclient_r.so.12 -> libmysqlclient_r.so.12.0.0 My setup is Red Hat Linux version 7.0. I used the latest mysql RPM (for Red Hat 7.0) from the mysql web-site Where can I go for help on this? If somebody has a suggestion, I'm all ears. FYI, using MySQL with PHP works like a charm from the command line and when called from a web-page. So, I know MySQL is there, ready to do my bidding. I looked through the latestMySQL manual concerning the C/C++ API; no help. thanks rick -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
