IPA with C program/libraries and fortran library

I’m trying to link a C program against some C and fortran libraries and am runnning into this problem:

IPA fatal error: function ‘_free’ multiply defined in: …/src/pgf90rtl.c
IPA fatal error: function ‘_free’ multiply defined in: …/src/libc.c
IPA fatal error: function ‘_malloc’ multiply defined in: …/src/pgf90rtl.c
IPA fatal error: function ‘_malloc’ multiply defined in: …/src/libc.c
IPA inhibited: multiply defined routines


I can’t seem to reproduce it in a minimal way, so here is my link statement.

pgcc -IZ:/ISLtools_v1.2/i686-pc-winnt-gnu/include -I…/…/…/src/scats -I…/…/…/src/scats/libscatsio -I…/…/…/src/scats/libscats -Ic:/cygwin/usr/local/include -Ic:/cygwin/usr/local/include -fastsse -O3 -Mipa=fast -Mvect=sse -s -m32 -DZ_PREFIX -o CellScatter.exe CellScatter.o -Lc:/PROGRA~1/PGI/nt86/6.0/mingw/lib -Lc:/PROGRA~1/PGI/nt86/6.0/mingw/mingw32/lib -Lc:/PROGRA~1/PGI/nt86/6.0/mingw/lib/gcc-lib/mingw32/2.95.3-5 -Lc:/PROGRA~1/PGI/nt86/6.0/lib -lpgmm1 -lpgmm2 -lpgf90 -lpgf90_rpm1 -lpgf902 -lpgf90rtl -lpgftnrtl -lpgsse1 -lpgsse2 -lpgc -lmingw32 -lmoldname -lmsvcrt -luser32 -ladvapi32 -lshell32 -lkernel32 …/libscats/.libs/libscats.lib …/libseke/.libs/libseke.lib …/libscatsio/.libs/libscatsio.lib -LZ:/ISLtools_v1.2/i686-pc-winnt-gnu/lib Z:/ISLtools_v1.2/i686-pc-winnt-gnu/lib/libisl.lib -Lc:/cygwin/usr/local/lib -lvsip -lmatio -lz -lmingwex


I get the same error if i remove the explicit linking against the fortran libraries and replace it with -pgf90libs and I get fortran undefined symbols obviously if I don’t use either method.

Stumped,

Hi Chris,

I’ll need to do a bit of investigation since off hand I don’t know why this would occur. Let’s try some things to at least get your program to link.

  1. Try linking with “pgf90 -Mnomain” instead of “pgcc”. Also remove all the “-lpg*” libraries.

  2. Since the errors are from pgipa, remove “-Mipa=fast” and re-link.

Part 2 works fine. Then again I think it just skips IPA and continues linking anyways.

pgf90 with -Mnomain gives the same error
