symbol table not found debugging python + C -

-

i have c module, compiled -g option, using of functions of module using python script. when run command - 

gdb -ex r -args python test.py

it shows-

reading symbols /usr/bin/python2.7...reading symbols /usr/bin/python2.7...(no debugging symbols found)...done. (no debugging symbols found)...done.

and while using gdb command list throws -

no symbol table loaded.  use "file" command.

what potential reason..?

what potential reason..

the reason /usr/bin/python2.7 compiled without debug symbols, , c module has not yet been dynamically loaded.

one way deal set deferred breakpoint on module initialization code. once hit breakpoint, list start working.

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
