Seems your linker does not search /usr/lib64/openmpi/lib
for libraries. So, yes, try -L/usr/lib64/openmpi/lib in the LDFLAGS R. On 07/05/2016 12:31 PM, Mahmood Naderan wrote:
I searched a lot about the parallel compilation of siesta and saw some question on the list. However, they don't report any success! Regarding the sckalapack, I may get related errors later! but let me explain step by step. I installed netcdf-devel.x86_64 (4.1.2) from the yum repository. Files actually exists as below /usr/include/netcdfcpp.h /usr/include/netcdf.mod /usr/include/netcdf.inc /usr/include/netcdf.h /usr/include/netcdf.hh So, I expect that the lines in your arch.make should work. # Tricky business ... NETCDF_INCFLAGS= -I/usr/include NETCDF_LIBS= -lnetcdf -lnetcdff #NETCDF_INTERFACE=libnetcdf_f90.a And it does! So, the next error is scalapack. Again, I installed scalapack-openmpi-devel.x86_64 (2.0.2) from yum repository and files are there as below # find /usr/ -name *scalapack* /usr/lib64/openmpi/lib/libscalapack.so.2 /usr/lib64/openmpi/lib/libscalapack.so /usr/lib64/openmpi/lib/libscalapack.so.2.0.0 /usr/share/doc/scalapack-common-2.0.2 # ls -l /usr/lib64/openmpi/lib/libscalapack.so* lrwxrwxrwx 1 root root     21 Jul 5 19:56 /usr/lib64/openmpi/lib/libscalapack.so -> libscalapack.so.2.0.0 lrwxrwxrwx 1 root root     21 Jul 5 19:56 /usr/lib64/openmpi/lib/libscalapack.so.2 -> libscalapack.so.2.0.0 -rwxr-xr-x 1 root root 5922720 Jan 19 21:17 /usr/lib64/openmpi/lib/libscalapack.so.2.0.0 So, I expect that the line in arch.make should work SCALAPACK_LIBS=-lscalapack However, I get this error /usr/bin/ld: cannot find -lscalapack collect2: ld returned 1 exit status make: *** [siesta] Error 1 It seems that I have to include a search path! Do you have any idea? Regards, Mahmood
