What happened?

I followed instructions for installing on macOS but I kept getting dbdimp.c:2796:12:error: incompatible integer to pointer conversion assigning to 'MYSQL_RES ' (aka 'struct MYSQL_RES ') from 'int' [-Wint-conversion] I succeeded only by adding to cflags switch: -Wno-error=int-conversion Complete successful cpanm command was: cpanm --configure-args="--libs='-L/usr/local/opt/mysql/lib -lmysqlclient -lz -lzstd -lssl -lcrypto -lresolv' --cflags='-I/usr/local/opt/mysql/include/mysql -Wno-error=int-conversion'" --force DBD::mysql

This is line 2796 in DBD::mysql 5.003:

For me (on Linux with GCC 13.2.1) this works without errors:

perl Makefile.PL --cflags "$(mysql_config --cflags) -Wint-conversion"
make

Version 5.004 worked for me too without need for that switch, Thank you
