Bugzilla Bug 125190

raster3d has a fixed g77 reference.

since gcc4 g77 is called gfortran

gcc -g -m486 -w -I/usr/include -I/usr/local/include -DGUNZIP -DIMAGEPIPE
-DTIFF_SUPPORT -DTIFF_INVERT -DJPEG_SUPPORT  -DPNG_SUPPORT -DLINUX
-DNETWORKBYTEORDER -Wl,-O1 -Wl,--sort-common -Wl,--enable-new-dtags
-Wl,-Bdirect -Wl,--as-needed -Wl,-hashvals -Wl,-zdynsort -o avs2ps avs2ps.c -lm
g77 -g -O -w -malign-double -o balls balls.f
make: g77: Command not found

after a manual link 
ln -s /usr/bin/gfortran-4.0.2 /usr/bin/g77

ebuild starts compiling but hangs:

the g77 fix is easy, just sed the Makefile.incl

and change the g77 to gfortran...

the problem is the compiler seg. fault, same happens with gcc 4.1.0

Created an attachment (id=84421) [edit]
patch for fix gfortan compile issues

Hi,

I've just changed the raster3d-2.7c to use the fortran.eclass which should
take care of g77 vs. gfortran issues (should be on the mirrors in an hour
or so). The attached patch fixes the remaining compile problems for me. 
Please try it out and report back.

Thanks,
Markus

works perfectly, apply and close.

well done Markus

Markus are you sure you fixed the eclass?

i ask this cause:

You need one of these Fortran Compilers: g77 ifc
 * Installed are:  ifc
 * Current Fortran Compiler is set to g77, which is not usable with this
package !

!!! ERROR: sci-libs/blas-reference-19940131-r2 failed.


i know it's completly unrelated to raster3d, but that seems not to work
properly.

Hi Patrizio,

Thanks for testing and I just committed the patch to cvs
which closes this bug. 

Regarding comment #5: I haven't done anything to the 
fortran.eclass but merely had the raster3d ebuild use it. Hence,
if there is a problem with blas-reference and the fortran.eclass
please file a bug and we'll have a look at it.

Thank you very much!

Best,
Markus
