[mpich-discuss] Changes to MPICH2

[Eduardo Kienetz]

For my graduation project I'll have to add a new flag to MPICH2's
configure script (--enable-peruse, for the record).
According to the Autobook
(http://sources.redhat.com/autobook/autobook/autobook_24.html#SEC24),
I should change configure.in , which will be read when I run autoconf,
generating the configure script. So, to test, I renamed the configure
script that comes with MPICH2 to old.configure and then ran autoconf,
which created a new configure script from the configure.in (unchanged)
that also comes with MPICH2. I noticed the new one has a different
size (smaller) than the one that came (old.configure) with MPICH2 and
is unusable. So, should I just change configure directly or are there
any special arguments to autoconf that I'm missing (or something
else)?

I'm using: autoconf (GNU Autoconf) 2.63

The errors I get when trying to run the newly built configure script are:
Configuring MPICH2 version 1.0.8
Running on system: Linux dv5 2.6.28ebk #2 SMP Sun Jan 11 19:28:13 BRST

./configure: line 2530: `PAC_VPATH_CHECK(src/include/mpi.h

Any help will be greatly appreciated,

Thank you in advance,
