[mpich-discuss] Cannot compile with debugging symbols

[Matthew Russell]

Hi,

I'm having problems building MPICH2 with debugging symbols.  I'm using OS X
Lion on an 86x64 box using PGI 10.9 as my compiler.

As far as I can tell, the issue is that the builder wants me to use the flag
-fpic to produce position independent code, but PGI doesn't support the
-fpic flag for OS X on a 64 bit machine.

My problem is with ./src/mpi/debugger/dll_mpich2.c, specifically, here is
the line the fails while i'm make'ing it.

/opt/pgi/osx86-64/10.9/bin/pgcc *-fPIC* -DHAVE_CONFIG_H -I. -I.

My configuration options were:

./configure --prefix=/usr/local/mpich2_pg-dbg --enable-f77
--enable-debuginfo --enable-error-messages=all --enable-g=all
--enable-fast=none


Does any one know how I can get around this?  I need the debug info, since
the program I'm trying to run with MPICH (CMAQ) seg. faults. right away, and
I don't know how else to debug it.

Note, with my installation (without debugging symbols), I can run all the
sample programs on multiple processors, etc.

Thanks,
