top-of-tree is failing to install from HEAD

Installing from HEAD is currently failing. It just hangs at this step at the end:

Unlinking /usr/local/Cellar/lnav/0.10.1... 2 symlinks removed.

I'm not seeing this anywhere else, can you run ps and see which process is blocked?

[mmashwani]

This looks ugly, but here's the output of that command attached lnav_head_install_ps.txt .

Just tried again and attaching the output of the ps command. lnav_head_install_ps_02.txt .

Ah, sorry, didn't realize you were using brew install --HEAD. For some reason, compiling the "data_scanner_re.cc" file with some optimizations takes a really long time. I had worked around this in the regular build, but it looks like brew is overriding some flags and that's making it take longer. I'll have to figure out how to ignore the brew overrides in the makefile.

[mmashwani]

Yup, when I came back a really long time later, it was all compiled. It must have happened because of a recent brew update because brew install --HEAD lnav was not taking this long until some time yesterday when I was updating all of the things.

I made a tweak to get that file to build faster. The build from HEAD on my M2 is now 1m37s. So, I'm going to close this.
