I have two issues:
[100528] WARNING at dmtcp_launch.cpp:762 in setLDPreloadLibs;
REASON='JWARNING(libdmtcp != "libdmtcp.so") failed'
libdmtcp = libdmtcp.so
Message: You appear to be checkpointing a 32-bit target under 64-bit Linux.
DMTCP was unable to find the 32-bit installation.
See DMTCP FAQ or try:
./configure --enable-m32 && make clean && make -j && make install
./configure && make clean && make -j && make install

[40000] WARNING at dlwrappers.cpp:75 in dlopen; REASON='JWARNING(ret) failed'
filename = libnspr4.so
flag = 5
Message: dlopen failed. You may also see a message 'ERROR: ld.so:'
from libdl.so. If this happens only under DMTCP, then consider setting
the environment variable DMTCP_DL_PLUGIN to "0" before 'dmtcp_launch'.
If the problem persists, please write to the DMTCP developers.
Are both related to the fact that DMTCP is compiled for 64 bit while the binary
app is 32 bit? It does go ahead even after this error though I could not try
checkpointing for some other reasons.
