Here a minimal working Makefile.linux:
# A pretty simple make file that should work on most Unix-like platforms
that have gcc.
OOREXX_LFLAGS = -lrexx -lrexxapi # needs to follow after file for which
link resoultion is needed
# What we want to build.
all: runRexxProgram stackOverflow
runRexxProgram: runRexxProgram.cpp
gcc runRexxProgram.cpp ${OOREXX_LFLAGS} -o runRexxProgram
stackOverflow: stackOverflow.cpp
gcc stackOverflow.cpp $(OOREXX_LFLAGS) -o stackOverflow
clean:
rm -f stackOverflow runRexxProgram
If there are no objections (Makefiles are sometimes religious), I would replace
the non-working
version with the above one.
