Hi, With Devel-Trace, I found the issue.
It seems the pidtable expects to match a line with two pids (numbers) folloed by a mandatory string, but for some reason I only have the pids. So I made that last part optional, and it seems to do the trick. Thank you for your help. --- /usr/local/bin/parallel.bak 2016-05-11 08:51:47.595661351 +0200 +++ /usr/local/bin/parallel 2016-05-11 08:51:56.823522828 +0200 @@ -4103,7 +4103,7 @@ # must match: 24436 21224 busybox ash # must match: 24436 21224 <<empty on MacOSX running cubase>> # or: perl -e 'while($0=" "){}' - if(/^\s*(\S+)\s+(\S+)\s+(\S+.*)/ + if(/^\s*(\S+)\s+(\S+)\s+(\S+.*)?/ or $^O eq "darwin" and /^\s*(\S+)\s+(\S+)\s+()$/) { $parent_of{$1} = $2; On 10 May 2016 at 17:08, Shlomi Fish <shlo...@shlomifish.org> wrote: > Hi, > > On Tue, 10 May 2016 16:28:45 +0200 > Gabriel Ganne <gabriel.ga...@gmail.com> wrote: > > > Yes I am. > > > > Do tell me if you need me to test anything. > > > > Thanks, > > > > I've now set up a CentOS 7.2.x x86-64 VBox VM and built and installed GNU > parallel and it seems to run fine - tested the --help flag and a sample > invocation - see the screenshot at: > > > http://www.shlomifish.org/Files/files/images/centos-7.x-gnu-parallel--shlomif.png > > Some things you can try to diagnose the problem: > > 1.
