The problem is ProjectCenter. I can add this
# Additional include directories the compiler should search
ADDITIONAL_INCLUDE_DIRS += -I/usr/include/
# Additional library directories the linker should search
ADDITIONAL_LIB_DIRS += -L/usr/lib/
# Additional GUI libraries to link
ADDITIONAL_GUI_LIBS += -lgsl -lgslcblas
at GNUmakefile.preamble but ProjectCenter don't read this file. If I
add this with other editor and compile my app from a terminal, I
don't get errors.. The problem is with ProjectCenter, The only way
is add this at the 'Project Inspector' but where can I add the flags
of ADDITIONAL_GUI_LIBS?. There is only fields to Preprocessor, ObjC
compiler,C compiler and Linker.
