Considering there's an official developer page through EDM2, perhaps the very first article should be "how to get started", with this information?

Hi,
If I'm not wrong most of it is already covered in some other places of these forums. Yet I must say I'm doing much research (in my almost zero spare time) to try and get up-and-running in as few steps as possible.
I'll try to gather and organize as much information as possible and try to contribute to what has already been written. Ad EDM/2 column would be really useful (provided it doesn't already exist!).

Quoting myself because I came across an interesting problem.
If I try to set variables like CFLAGS like this
--- Code: ---set CFLAGS=-O2 -g
--- End code ---
configure and autoreconf work correctly. But I can't set options like -march or -mtune. If I try to set these in double quotes as in
--- Code: ---set CFLAGS="-O2 -g -march=generic"
--- End code ---
even after autoreconf, configure fails giving me troubles in gcc, gxx and cpp - even if I tweak the script.
How can I include -march / -mtune and similar options?
This happens also if I try to use export directive in a shell script...

What error message do the compilers give you?

It's not a compiler error, instead it's configure complaining that the compiler found "can't produce executables". If I set the environment variables without double quotes everything works perfectly (I just finished libfftw-3.3.10).
But, if I don't use double quotes, I can't put -march or -mtune in a CMD file or a shell script.

Jochen Schäfer:
I use double quotes in the environment variables, too.
PS: "Couldn't build executables" is configure's answer to the compiler erroring out.
In configure.log everything is logged. You can see, how the compiler gets called by configure and what answer it gets.

Try,
