[Wien] Error while loading shared libraries

[Gerhard Fecher]

As the Intel compiler manual tells,
for 32 bit systems the setting of ulimit may not influence the behavior at runtime at all.

Note: The size of {\it "unlimited"} varies by {\scshape Linux}
configuration, so you may need to specify a larger, specific number to
{\it ulimit} (for example, 999999999). On {\scshape Linux} also note
that many 32bit {\scshape Linux} distributions ship with a pthread
static library ({\it libpthread.a}) that at runtime will fix the
stacksize to 2093056 bytes regardless of the {\it ulimit} setting. To
avoid this problem do not link with the {\it -static} option or the
{\it -fast} option. Instead of {\it -fast}, use options: {\it -ipo -O3
-no-prec-div -xP}. This only affects the 32bit {\scshape Linux}
distributions and does not apply to the 64bit {\scshape Linux}
distributions.


Check youre settings you have 3 different versions given below.
/opt/intel/fc/9.1.036/bin/ifort
/opt/intel/mkl/9.0/lib/32 -lguide -lpthread
/opt/intel/mkl/9.1.023/lib/32 -lmkl_lapack -lmkl_ia32 -lmkl_lapack -lmkl_ia32


Somehow I feel very tired

Hi Chandrika,

Thanks for your reply.
Now I see the following segmentation fault error.

forrtl: severe (174): SIGSEGV, segmentation fault occurred

Following suggestions available in mail-list digest, I have done the following:

In .bashrc (or equivalent) insert: ulimit -s unlimited.
In lapw0para and x_lapw insert: limit stacksize unlimited.

Still I see the same error. Also is it ok to insert "limit stacksize unlimited" anywhere in the mentioned files?

I appreciate your help.
Thanks,
Zubaer

Hi Zubaer,
Yes you need to add the compiler and mkl library paths to ld.so.conf and bashrc (or equivalent) in /etc. You will find details in earlier mails.
Best wishes,
Chandrika

Subject: [Wien] Error while loading shared libraries

Hi,
I am getting following error while running x nn.

/home/hossain2/WIEN2k/nn: error while loading shared libraries: libguide.so: cannot open shared object file: No such file or directory
0.000u
 0.000s 0:00.00 0.0%    0+0k 0+0io 0pf+0w
error: command   /home/hossain2/WIEN2k/nn

I have following settings
Compiler:
/opt/intel/fc/9.1.036/bin/ifort
Options:
current:FOPT:-FR -mp1 -w -prec_div -pc80 -pad -ip -O3
current:FPOPT:-FR -mp1 -w -prec_div -pc80 -pad -ip -O3
current:LDFLAGS:$(FOPT) -L/opt/intel/mkl/9.0/lib/32 -lguide -lpthread
current:DPARALLEL:'-DParallel'
current:R_LIBS:-L/opt/intel/mkl/9.1.023/lib/32 -lmkl_lapack -lmkl_ia32 -lmkl_lapack -lmkl_ia32
current:RP_LIBS:-L /usr/local/SCALAPACK -L /usr/local/BLACS/LIB -lpblas -lredist -ltools -lscalapack -lfblacs -lblacs -lmpi

Do I need to add the path of libguide.so somewhere? What location by default the linker searches for libguide.so?

I see the file is available at /opt/intel/fc/9.1.036/bin/lib/

I appreciate any help. Thanks in advance.
