Hi,
I guess I solved the problem with safe malloc but this time I have a problem with DBG_ON.
Although I have
INCLUDES = -DMYSQL_DYNAMIC_PLUGIN -DDBUG_ON -DSAFE_MUTEX -DUNIV_MUST_NOT_INLINE
-DEXTRA_DEBUG -DFORCE_INIT_OF_VARS -DSAFEMALLOC -DPEDANTIC_SAFEMALLOC -DSAFE_MUTEX
$(MYSQL_INC)
in the Makefile.am of my custom engine and I know that mysql runs in debugging mode, I
have this error:
Can't open shared library '/.../mysql_debug/lib/mysql/libStream_engine.so' (errno: 22
undefined symbol: _db_pargs_)
How can I check where the problem is?
