114.20+69 fails to build due to parallelism

[bogdan2412]

Seems like there's some dependency that's not tracked properly by the build system. opam install re2 --jobs 1 works fine.

Regular opam install re2 fails with the error below. Running make twice in the build directory also results in a successful full build.

I think that this is fixed by4c346e5ffbfa3e58ab52214aba01a75770632dfa, can you try again?

[bogdan2412]

It didn't fix it unfortunately. I should mention that this was on a Fedora 25 install and the default parallelism under which I see this failing is -j4.

Ok, there might a dependency missing when building the cmxs, looking into it

[ghost]

I believe this is fixed now

[bogdan2412]

Agree, thanks.
