Hi all,

I have done some editing to sql/item_cmpfunc.cc file and CMakeList filesand then when I run the make command( after running cmake) it halts with this error in the middle. ([68%])

Linking CXX executable explain_filename-t /usr/bin/ld.bfd.real: cannot find -lregex collect2: error: ld returned 1 exit status make[2]: *** [unittest/mysys/explain_filename-t] Error 1 make[1]: *** [unittest/mysys/CMakeFiles/explain_filename-t.dir/all] Error 2 make: *** [all] Error 2

what might have gone wrong. :(

You can run with "make VERBOSE=1" then you'll see the exact command that make is using for linking.

Anyway, this can have one of the two reasons. Either the linker thinks that "-lregex" is a file, and cannot find it (unlikely, but possible, depends on what else is on the command line).

Or it simply cannot find the library - libregex.so (or libregex.a). You need to specify a path to the library with the linker flag -L/path/to/the/library

Regards, Sergei
