Re: Error trying to exec cc1d...

[Angelo Graziosi <Angelo dot Graziosi at roma1 dot infn dot it>]

Hmm... I think it is a problem with GCC-4.6.3 on Kubuntu 12.04...

In this context, the .d files, like foo.d, are not source of D language 
but "dictionary" files generated in true software by other applications (I 
don't know D but try cat foo.d...). Only on Kubuntu/Ubuntu (now I have 
verified also on Ubuntu 12.04...) with gcc-4.6.3 it is thinking that foo.d 
is a D source file!

On: Cygwin (gcc-4.5), Fedora 16 (gcc-4.6.3), Mac OS X (Macports gcc-4.6.3) 
there is ONLY a warning (btw, I have verified it occurs since Nov. 2010! 
and the built software has worked fine on different systems), i.e.

$ gfortran -c foo.d foo.F
gfortran: warning: foo.d: linker input file unused because linking not done

On these systems I have no D compiler, just like on Kubuntu/Ubuntu!

...and it is not all.. Indeed I have just installed, on Kubuntu, gcc-4.8 
nightly builds:

http://gfortran.com/download/x86_64/nightlies/gcc-trunk-20120826-r190682.tar.xz

With it I have

$ ./gcc-trunk/bin/gfortran -c foo.d foo.F
gfortran: warning: foo.d: linker input file unused because linking not 
done

.i.e., it works as on other systems!!!

For completeness, on Kubuntu the failing gcc-4.6.3 was built with:

$ gfortran -v
Using built-in specs.

...perhaps on Kubuntu it doesn't like some "--enable..."?


Ciao,
