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
