Okay, those instructions are pretty helpful. Now things are getting
complicated:
The application I want to RPM contains 4 components. Building the package
manually look like:
cd component1
/configure
make
make install
cd ..
cd component2
/configure
make
make install
.
.
.
The components are dependant: I can't run make on component2 before making
and installing component1.
It seems to me the only way to do this is put everything in the build
section of the RPM, and just the final make install (of component4) in the
install section. This seems to break the logic of RPMs, though.
Does anyone have any suggestions? Is there another way to do this?
