the dynamic InnoDB plugin, ha_innodb.so. This libtool option cannot be used on every target platform. For instance, the AMD64 (x86_64) ABI mandates position-independent code (PIC) in dynamic shared objects. Makefile.am: Use $(INNODB_CFLAGS) and $(INNODB_DYNAMIC_CFLAGS) in target-specific CFLAGS and CXXFLAGS variable definitions. plug.in: Instead of appending to the MySQL-wide CFLAGS, introduce the variables INNODB_CFLAGS and INNODB_DYNAMIC_CFLAGS. Depending on $target_cpu, append -prefer-non-pic to INNODB_DYNAMIC_CFLAGS.
