qmake autotools

Message 1 in thread

using: qt 3.3 kdevelop 3.5

Hi,
I am making an interface for an existing program that uses autotools, so 
it has a configure.ac and a Makefile.am. Instead of using autotools, I 
wanted to use qmake. I tried, but I seem to have problems, is there any 
easy way to do that? or is it possible to use autotools. Is there 
anything simpler?
Thanks,
Marie

Why do you want to use qmake, if the project already works with
autotools?

You'd need to convert this into qmake syntax, but I think not much of
this is needed with qmake. Probably only the opengl parts. Note that
depending on the exact meaning of those macro's (I didn't look very
close) it might be nearly impossible to do this with plain qmake.
Autotools are much more complex than qmake.

And no there's no automatic way to do the conversion.

I can see one reason to use qmake, rather than autotools.

Qmake is more readily available on Windows, for those who do cross-platform development.

But within the unix/linux environments, autotools is more powerful, yes.

There's as well a solution for that problem, i.e. a powerful but
portable buildsystem: CMake.
