[mpich-discuss] Assembler messages at build ?

[Lou Picciano]

Gentlemen,

First, let me thank you again for the support on this - you're conveying a sense of community others could learn from!

Before wasting more of your time on this, let me double-check on all progress on our (project's) gcc; we have a couple of geniuses focusing on just this - I need to confer with them. Your comments convince me we have issues with the compiler itself. 'Enhancements' to gcc are an ongoing exercise, as we intend to use it to build the entire distro, from the kernel up.

I'll get back to you with progress.

Lou Picciano

Use the environment variables FC and F77 respectively to select compatible Fortran compilers.  The check here tests to see if a main program compiled with the Fortran 90 compiler can link with a subroutine compiled with the Fortran 77 compiler.

The very first error you reported seems to be caused by gcc. Let’s disable fortran first to see if gcc works in 64-bit. Try using the following command to disable fortran build:

./configure --disable-f77 --disable-fc
make

So it does support bit-64.

Seems *significant* tweak is needed to port newest gcc. I don’t know if it’s worth a try. Or have you seem this error happened while compiling other C source code instead of MPICH?
