I would imagine the results will be the same with a clean build, so shouldn't be required.

Not sure when the next version of flex is out, but until then it might be easier just to go back to the older version

I tried the change (I think), and I got the same errors. How I tested:
I changed build-flex.mk back to the 2.6.4 version.
hg -v pull
hg -v update
touch src/build-flex.mk
time make hg-octave-dist

  • fails same way on build-flex

comparing the log with the last log they are almost identical accept for an additional line with
showing the patch seems to have been applied, and a line showing make ... -j '1' instead of make ... -j '4', a lot of re-ordered lines, and the final times were different. I could try building from a completely clean build/new repo, but I don't expect different results and it takes forever to build from that point. I'll do it though if you think that will give useful results.

I pushed a change which may fix flex - http://hg.octave.org/mxe-octave/rev/a0e30199373f

When flex is set to use version 2.6.4 in mxe-octave/src/build-flex.mk, then I get a build failure. I'm running Ubuntu 17.10 on virtual box, to compile a windows installer. If I change the version to 2.6.3 (and checksum to 5ca32baa607ed32aa069e18d6d60b9761e1e6538), then It will compile.

I am using the following configure options:
./configure --enable-devel-tools --enable-octave=default --enable-qt5 --enable-64 --enable-windows-64
From a working build changing back to the original build-flex with version 2.6.4, and running the following, it fails again:

I geet the following error:

from /home/marshall/mxe-octave/log/build-flex, I get the following details:
There seems to be several possibly related bugs reported to flex,
https://github.com/westes/flex/issues/219
https://github.com/westes/flex/issues/265
I'm not sure if any of those fixes apply, but in any case, building flex fails when run from a clean repo/build of mxe-octave.
