I develop C/C++ using the Eclipse IDE. Eclipse also generates a makefile which I don’t want to edit as it will simply be overwritten.
I want to use that makefile for nightly build within Hudson.
How do I pass #defines which are made in the project file of the IDE to the makefile ? (and why doesn’t Eclipse already include them in the generated makefile?)
I actually had this figured out once, then accidentally overwrote it 🙁 But at least I know that it can be done…
If you are running make from the command line, use
which will add -DFOO to all compilations. See also CFLAGS, CXXFLAGS, LDFLAGS in the make manual.
