My experience is that IDE's are really slow at making their makefiles.
If you've got an Eclipse project with a few directories and a bunch of
C, C++ and H files in them, then doing a "rebuild" after changing a
header file means Eclipse will first grind through all the C and C++
files doing (approximately) "gcc -MM" to figure out the dependencies to
generate the makefile.  Then it will do the full compilation on the
files that actually need to be re-compiled.  And while "gcc -MM" is a
good deal faster than a normal compile, it adds up when the IDE does it
for /all/ the project files.

My makefile generates the dependency files when it needs to - and
re-generates them when it needs to.  So for quick re-builds after small
changes, it is much faster than Eclipse's built-in project management.

My brief experience with MSVS was no better here.  But perhaps netbeans
or other IDEs are not as inefficient as Eclipse in this regard.


I also prefer a proper makefile because it is then independent from the
IDE.  If I need to re-open an old project (and my record is close to 20
years old) I have the compiler at hand, but I really hate having to
install some ancient IDE just to do the build.  It is also far easier to
make a fix via ssh from a mobile phone when building is done my "make"
and not "Tools | Build" in an IDE!
