gnat-gcc 4.4.1 configure: error: C compiler cannot create executables

[rperrot@…]

Hi,

I'm trying to install gnat-gcc using gnat-gpl variant and it ends with that error :

"configure: error: C compiler cannot create executables"

here s an extract of config.log :

See `config.log' for more details.

I think the problem is the -arch option that cause this issue. Is there a way of turning-off that option ?

I suggest to use the binary package provided from The GNU Ada Project:

​http://sourceforge.net/projects/gnuada/files/

mind you: the compile on Snow Leopard still won't work - but at least you have a working compiler.

[rperrot@…]

It doesn't seem to compile on Leopard too ...

port install gnat-gcc +gnuada ends with :

...
i686-apple-darwin9-gcc-4.0.1: xnmake.adb: Ada compiler not installed on this system
...

i686-apple-darwin9-gcc-4.0.1? Now this seems very wrong! With the mentioned variant /opt/local/bin/gcc-gnat-4.4 should have been used instead.

Also note that with +gnuada you will ultimately need to force (-f) the installation as gnat-gcc-4.4.2.dmg already installed a compiler to /opt/local.

Here is the full error message :

As you can see CC_FOR_BUILD, CC, CXX seem to be OK but I don't understand why i686-apple-darwin9-gcc-4.0.1 is used then ...

It's noted ! ;)

I am currently working on gnat-gcc 4.5.1 - any 4.4 bugs won't be fixed. gnat-gcc is a very time consuming port - any help is welcome. Drop me a mail an I send you the current Portfile and test scripts.
