[CPMD-list] pthread compilation problems

[arnaud marmier]

Hello,

   I'm trying to compile CPMD-3.9.2 on an opteron

   I got a sequential version easily enough, but am having trouble with 
the MPI.

   Essentially I get the following kind of errors :

/usr/local/Cluster-Apps//mpi/gm/pgi/64//1.2.6..14a.1/lib/libmpich.a(gmpi_malloc.o)(.text+0x48c7): 
In function `mALLOPt':
: undefined reference to `pthread_mutex_lock'
/usr/local/Cluster-Apps//mpi/gm/pgi/64//1.2.6..14a.1/lib/libmpich.a(gmpi_malloc.o)(.text+0x49ee): 
In function `.st3894':
: undefined reference to `pthread_mutex_unlock'
make: *** [cpmd.x] Error 2

   After checking a bit more it seems that the mpich library has been 
compiled using threads and that I need to link to the threading library. 
  I have tried adding -lpthread to the FFLAGS, even copying some of the 
libpthread.a libs in the SOURCE directory, but to no avail.

   I include the Makefile Header for info :
