[Dmtcp-forum] checkpointing Julia: bannedSignalNumber and dlopen issues

[Philippe M. <phi...@un...>]

Hi,


1) I'm note able to checkpoint julia scripts, even by setting the 
environnement DMTCP_SIGCKPT to ...other number(!) than the default (12) 
variable

2) I also deal with a lot of dlopen warnings and errors that I can shut 
up by setting DMTCP_DL_PLUGIN to "0". Is there a way to avoid cleanly 
those dlopen/dlwrappers issues ( libs of julia LD_LIBRARY_PATH or 
something like that...before compilings dmtcp or just in runtime?)

version : 3.0.0 (Github version)
compilation: no issues
make Check: 66/66 TESt PASSED
small personal tests in fortran, C , python are OK...Matlab R2018a also 
(with some insults :-))

Thanks in advance,
Philippe

command : dmtcp_launch ./compteurf.jl
