FEFLOW crashes in linux

Hi

I installed FEFLOW 6.1 on linux Slackware 14.0. It instaled fine but each time I try to open a *.fem file I get the following error message:

/opt/wasy/bin/feflow6110q: symbol lookup error: /usr/lib64/libfeflow61.so.6.1: undefined symbol: __kmpc_atomic_fixed8_orb

Thanks for your help.

Do you have your LD_LIBRARY_PATH variable set to include /opt/wasy/lib64 (or wherever you installed FEFLOW?). It looks like you have stuff installed in a mixture of prefixes: /usr/lib64 and /opt/wasy

E.g. with everything stored under the prefix /opt/wasy
[code]
$ LD_LIBRARY_PATH=/opt/wasy/lib64 ldd /opt/wasy/bin/feflow6110q
linux-vdso.so.1 =>  (0x00007ffff13ff000)
libfeflow61.so.6.1 => /opt/wasy/lib64/libfeflow61.so.6.1 (0x00007f8c7e442000)
        ...
$ readelf -Ws /opt/wasy/lib64/libfeflow61.so.6.1 | grep "__kmpc_atomic_fixed8_orb"
  578: 0000000000000000    98 FUNC    GLOBAL DEFAULT  UND __kmpc_atomic_fixed8_orb
[/code]

Thanks a bunch. That took care of it. It is working now.

LD_LIBRARY_PATH=... only worked once. I had to run it everytime for FEFLOW to work. A permanent solution is to add /opt/wasy/lib64 to the file /etc/ld.so.conf and then run ldconfig. After that the change is permanent and works for all users. You have to be root to make these changes.
