Should we simply avoid that issue, or should we be including > 32-bit libraries in /usr/lib32? would that simply create a 32-bit separate build or "enable" checkpointing of 32bit apps on 64bit system using 64-bit built dmtcp_coordinator/dmtcp_checkpoint? ,--- | following messages on my attempt: | *** ERROR: You appear to be checkpointing a 32-bit target under 64-bit Linux. | *** If this fails, then please try re-configuring DMTCP: | *** configure --enable-m32 ; make clean ; make | | ERROR: ld.so: object '/usr/lib/dmtcp/dmtcphijack.so' from LD_PRELOAD cannot be preloaded: ignored. `--- suggests that it is the later case... but after rebuilding with --enable-m32, everything is just 32bit, so now 64bit apps cannot be checkpointed, thus it seems to be the former :-/ So, probably for now -- just forget about it... later on you might like to provide ia32-dmtcp binary package for amd64 platform, so someone needing checkpointing of 32bit apps on 64bit system could simply use ia32_dmtcp_* tools? or may be, ideally, all those tools could automagically choose which build to use (if both are available)? but I guess that all could be 'TODO' and you might like to adjust the above ERROR message to make it clear that it is not just a reconfiguration to add an optional support of 32bit on 64bit systems -- it requires a complete 32-bit only build. > 2) > A small number of source files are modified from glibc source files. > You can find them by doing: > grep -r 'This file is part of the GNU C Library' ./ > Both DMTCP and GLIBC use the LGPL license.
