[Mingw-users] bash 4 for MSYS

[Paul J. Hentschel]

Hello everyone. I am new to the list. I have been playing around
with building bash 4.1 for MSYS. I have what I think is a working
build, but I was hoping to get some feedback on how to go about
testing it, besides just installing and using it and see if anything
goes wrong.

I have a repository on github here if anyone is interested:
https://github.com/hpmachining/msys-bash-build
You need to checkout branch 4.1 after cloning, master is just a
few scripts. I didn't include the bash source or upstream patches
in the repository, but there is a script, download_sources, that
will download them. Or, of course, you can download them manually
from here: https://ftp.gnu.org/gnu/bash/

BTW, the reason I am doing version 4.1 is because after this
version, there is a problem with command substitution not
working. A simple $(echo ls) or `echo ls` doesn't work.

Thank you for your work.

Does Bash have a test suite? If it does, I'd start by running it and
making sure all the tests pass. Maybe you did that already.

The next step I'd recommend is to run the configure and make parts of
building complex packages, and see that this works as well as the
existing MSYS Bash does.

I did run the test suite but there are issues with both the official MSYS
bash package
and my attempt at a port, so I don't really know how to interpret the
results. For one
thing, a few of the tests can't find the msys-1.0.dll. I will provide the
log files if anyone
wants to see them.

I built a few smaller packages then built gtk2 without any issues, so it's
looking good
so far. Thank you for your suggestions.

I see that MSYS2 has Bash 4.3, so perhaps you could look in their
patches to see how they solved this.

Thanks, I'll look into that. I wanted to get a working bash 4 build to use
for
comparison before trying to figure this out. If anyone knows what specific
files in the bash source I should look at, that would be a big help.
