looks like the problem was that Guix runs make with -j set to >1 by
default, and the Makefile isn't written with parallelism taken into count.
adding --jobs=1 to make arguments in the package recipe fixed the issue :)
I should probably send in a bug report to ECL
isn't ecl unmaintained now
ugh, there's already a bug report for this issue anyway
oh but that's from 2009 and supposedly closed, so it must have been
oh, closed because "We do not support parallel builds of ECL."
wonder if a Makefile can't declare that limitation?.. w/e
A check of the Gnu Make manual finds:
You can inhibit parallelism in a particular makefile with the
If `.NOTPARALLEL' is mentioned as a target, then this invocation
of `make' will be run serially, even if the `-j' option is given.
Any recursively invoked `make' command will still run recipes in
parallel (unless its makefile also contains this target). Any
prerequisites on this target are ignored.
The below seems to save us from default-to-parallel makes.
