Hi experts I am a newbie when it comes to compiling sources the debian way. So please bear with me for this stupid question. I wanted to compile mpich2 using gfortran and gcc. gfortran currently is available only in gcc-snapshot package. So I am using gcc-snapshot package to build the packages (even though it is advised not to do that). But when I am compiling mpich2, I am getting some warnings regarding architecture inconformance.
I am using Debian Sid, kept upto date with the debian servers. To reproduce the problem just do the following. sudo apt-get install gcc-snapshot LD_LIBRARY_PATH=/usr/lib/gcc-snapshot/lib:$LD_LIBRARY_PATH PATH=/usr/lib/gcc-snapshot/bin:$PATH wget http://torvalds.cs.mtsu.edu/~zach/debian/1.0.1/mpich2_1.0.1-1.diff.gz \ http://torvalds.cs.mtsu.edu/~zach/debian/1.0.1/mpich2_1.0.1-1.dsc \ http://torvalds.cs.mtsu.edu/~zach/debian/1.0.1/mpich2_1.0.1-1_i386.deb \ http://torvalds.cs.mtsu.edu/~zach/debian/1.0.1/mpich2_1.0.1.orig.tar.gz dpkg-source -x mpich2_1.0.1-1.dsc cd mpich2-1.0.1 dpkg-buildpackage -rfakeroot At this point you there will be warnings as follows dpkg-architecture: warning: Unknown gcc system type i486-linux-gnu, falling back to default (native compilation) dpkg-architecture: warning: Specified GNU system type i386-linux does not match gcc system type i486-linux-gnu. dpkg-architecture: warning: Unknown gcc system type i486-linux-gnu, falling back to default (native compilation) dpkg-architecture: warning: Specified GNU system type i386-linux does not match gcc system type i486-linux-gnu. dpkg-buildpackage: host architecture is i386 dpkg-architecture: warning: Unknown gcc system type i486-linux-gnu, falling back to default (native compilation) dpkg-architecture: warning: Specified GNU system type i386-linux does not match gcc system type i486-linux-gnu. dpkg-architecture: warning: Unknown gcc system type i486-linux-gnu, falling back to default (native compilation) dpkg-architecture: warning: Specified GNU system type i386-linux does not match gcc system type i486-linux-gnu.

I hope it is not a problem. thanks for any ideas raju -- friends don't let friends use windows.
