After installing codeblocks from abinary slackware pkg [Latest Version], I get that while starting the app up !
codeblocks: relocation error: codeblocks: symbol _Z23wxHandleFatalExceptionsb, version WXU_2.8 not defined in file libwx_baseu-2.8.so.0 with link time reference
However, I compiled that too --> http://www.wxwidgets.org/downloads/ from source !!
