After having time to look closer, it turns out that the Makefile.linux has been
faulty! Here a
version that works (a little bit simplified and removed a superfluous
definition, the link switches
now trail the file to be created):
OOREXX_LFLAGS = -L. -ldl -lrexx -lrexxapi
OOREXX_CFLAGS = -fPIC
# What we want to build.
all: runRexxProgram stackOverflow
runRexxProgram.o: runRexxProgram.cpp
gcc -c $(OOREXX_CFLAGS) -o runRexxProgram.o runRexxProgram.cpp
runRexxProgram: runRexxProgram.o
gcc runRexxProgram.o -o runRexxProgram $(OOREXX_LFLAGS)
stackOverflow.o: stackOverflow.cpp
gcc -c $(OOREXX_CFLAGS) -o stackOverflow.o stackOverflow.cpp
stackOverflow: stackOverflow.o
gcc stackOverflow.o -o stackOverflow $(OOREXX_LFLAGS)
clean:
rm -f *.so *.o stackOverflow runRexxProgram
Will commit the changes to this Makefile tomorrow.
