No Makefile generated on MSYS2: make: *** No targets specified and no makefile found. Stop

[hakonhagland]

I am trying to install a debug version of perl 5.32.0 on Windows 10, using MSYS2. After applying the fix for symlinks in #18037 I get:

$ wget https://www.cpan.org/src/5.0/perl-5.32.0.tar.gz
$ tar zxvf perl-5.32.0.tar.gz
$ cd perl-5.32.0
$ sh Configure -de -Dprefix=$HOME/myperl -DDEBUGGING -Dman1dir=none -Dman3dir=none

Configure done.

If you compile perl5 on a different machine or from a different object
directory, copy the Policy.sh file from this object directory to the
new one before you run Configure -- this will help you with most of
the policy defaults.

$ make
make: *** No targets specified and no makefile found.  Stop.

By inspecting Makefile.SH I see that on line 1754 it deletes makefile:

$rm -f $firstmakefile

(since $firstmakefile is equal to makefile). But I believe in MSYS2 case does not matter so it deletes the newly generated Makefile instead (note capital M).

[hakonhagland]

If I change the definition of firstmakefile on line 696 in the generated config.sh to:

firstmakefile='makefile2'

and rerun Makefile.SH it does not delete the generated Makefile. So this is just a quick fix to be able to run make

I had this exact same issue in a centos:7 container that had a bind mount to a folder on my Mac. I believe its due to the case insensitive file system.

The issue easily reproduced in a container by executing the following:

# place perl-5.34.0.tar.gz in ./test locally
docker run --rm -it -v $(pwd)/test:/test centos:centos7 /bin/bash
# in the container
cd /test
yum install -y make gcc
tar xvzf perl-5.34.0.tar.gz
cd perl-5.34.0
./Configure -des -Dprefix=$HOME/perl5 -Dusethreads

Then when running make you then get an make: *** No targets specified and no makefile found. Stop. error. This is because the Makefile gets deleted like in your example.

Does it work if you add firstmakefile='GNUmakefile' to hints/msys.sh? Or just a -Dfirstmakefile=GNUmakefile argument to Configure?

[ehenrion]

@Leont Yes it does :)

Me and @Corion have been working on a branch to make msys2 work out of the box, most recently at https://github.com/Perl/perl5/issues/18489
