Try to compile with pthread support.
"gcc -pthread"

Compiled with gcc and option -maix64
Executable version is created now, execution gives

Let's try now what xlc with option -q64 does

The mysql server build is 64bit. By default, AIX development env is 32bit. So you need to pass "-q64" for xlc & "-maix64" for gcc. Another option is to set OBJECT_MODE=64.

Hello,
I have a working community-mysql-server 8.0.20 on aix 7.2
mysql --version
mysql Ver 8.0.20 for AIX on powerpc (Source distribution)
C-API library is installed in
ls -l /opt/freeware/lib/libmysqlclient.a
-rwxr-xr-x 1 root system 8703555 Mar 10 08:40 /opt/freeware/lib/libmysqlclient.a
When I compile following program "version.c" with IBM xlc compiler
#include <mysql.h>
#include <stdio.h>
int main()
{
printf("MySQL client version: %s\n",mysql_get_client_info());
}
xlc -c version.c -I/opt/freeware/include/mysql
a version.o object file is created that's OK, no errors while compiling to an object file
But when I compile it to an executable "version" program, the compiler doesn't find the function in the library
xlc -o version version.c -L/opt/freeware/lib -lmysqlclient
ld: 0711-317 ERROR: Undefined symbol: .mysql_get_client_info
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
Is that because the the program compiled witth IBM xlc compiler is linked to libmysqlclient.a that was compiled with another compiler ?
I tried to compile with gcc-8 too but that does the same
ld: 0711-317 ERROR: Undefined symbol: .mysql_get_client_info
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
What can be the reason that compiler doesn't find the function in lib ?
Kind regards,
Johan Volders
