undefined reference to `pthread_atfork

[hbarsch]

I try to compile GAMESS on x86-64 using ifort & MKL. When I try to link it, I get the following error message:

• undefined reference to 'pthread_atfork'

There have been many more undefined references until I added libguide.a to the libraries to be linked to. Do I have to specify any other library to resolve this problem? Thanks for any hints.

Regards,

Hannes

Follow one of the examples which link against libguide and libpthreads, or use ifort -openmp to cover both of those.

I used this configuration with success :

#
# Define the options for the system loader 'ld'. These are
# LDR - the name of the loader (usually a compiler).
# LDOPTS - options, such as asking for a load map.
# LIBRARIES - extra system libraries which must be searched.
# BLAS - set to blas.o if not using system BLAS.
# set to blank if using system BLAS.
# VECTOR - set to vector.o on a vector processor.
# set to blank on a scalar processor.
# QUICHE - set to zunix.o if using true dynamic memory,
# possibly add other system specific objects.
# set to blank otherwise.
#
# --- start of machine specific options ---
#
if ($TARGET == amd64) then
set LDR = 'ifort'
set LDOPTS='-O2 -xP'
# set LDOPTS="$LDOPTS -fastsse -Mipa=fast,safe -Mprof=func"
set VECTOR=' '
# if (-e /usr/lib64/libblas.a) then
set LIBRARIES='-L/opt/intel/mkl/8.0/lib/em64t/ -lmkl_em64t -lguide -lpthread'
set BLAS=' '
# else
# set LIBRARIES=' '
# set BLAS='blas.o'
# endif
set QUICHE='zunix.o'
# endif
endif


If you compiled the rest of gamess with ifort, could you share with me the compilations options you used in the "comp" script?
