Hello all,
As some surely had read, I had problems compiling and linking the fltk
example in two steps. The following makefile didn't work:
------------
CC = $(shell fltk-config --cxx)
CXXFLAGS = $(shell fltk-config --cxxflags)
LDFLAGS = $(shell fltk-config --ldflags)
hello : hello.o
clean :
for f in hello.o hello; do if [ -f $$f ]; then rm $$f; fi; done
-----------
The reason is, that the the build in rule gives $(LDFLAGS) befor the .o
files. Because ld works in one pass, it cannot resolve the symbols in
the .o files using the libraries.
The following makefile does the job:
-------------
CC = $(shell fltk-config --cxx)
CXXFLAGS = $(shell fltk-config --cxxflags)
LDLIBS = $(shell fltk-config --ldflags)
hello : hello.o
clean :
for f in hello.o hello; do if [ -f $$f ]; then rm $$f; fi; done
-------------
$(LDLIBS) comes after the .o files. So I would suggest an option --ldlibs
for the libraries.
Greetings, Dieter
