Ubuntu 18.04 on WSLv1 issues: makedepend deletes Makefile + installman fails + microperl build fails (requires perlio instead of stdio)
On my machine this script leads to no makefile found (and indeed, only Makefile.micro exists which errors out as well):
PERL=https://github.com/perl11/cperl/releases/download/cperl-5.30.0/cperl-5.30.0.tar.gz
wget -nc $PERL
tar xfz $(basename $PERL)
PREFIX=$PWD/cperlprefix
mkdir -p $PREFIX
cd cperl-5.30.0
./Configure -sde -Dprefix=$PREFIX
make -j4
My platform is Ubuntu 18.04 on WSLv1. Typically this is sufficient for building all programming language runtimes.

If you compile cperl 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.

Context: I am looking to use perlcc / RPerl to convert tlmgr from TexLive into C/C++ code, so I thought to install locally a recent, updated Perl distribution - cperl.
That's an syscall-emulated linux subsystem on Windows. Not sure if that matters. Most of user-space things work and build from source fine there (all programming languages, etc)
If you can suggest, where to put debug prints in ./Configure, I can do some debug printing
I ran bash -x Makefile.SH and strace -f bash Makefile.sh, output is attached
cperl-5.30.0.zip
++ osname=linux
++ osvers=4.4.0-19041-microsoft
I think the problem is a case-insensitive filesystem under linux.
We write to Makefile, but then rm -f makefile, i.e. $rm -f $firstmakefile in Makefile.SH
Can you try commenting out this line?
(See the very end of bash,txt)
A fix would need to probe for a case-insensitve filesystem, store it in config and don't do this line.
Another temp. fix would be
# for case-insensitive filesystems (ie WSL)
mv Makefile Makefile.new
$rm -f $firstmakefile
mv Makefile.new Makefile
This helped to get Makefile generated! Thank you! I'll post here how it compiles (given that Makefile.micro does not compile)
make succeeds. make install works and then prints:

readline() on closed filehandle $fh at installman line 115.
not sure if it's expected or not
ls cperlprefix/bin does not contain any perl executable:

perl executable is produced by make and runs launches successfully, but it is not copied into cperlprefix/bin because of failed make install. If it's a problem while installing man, is there a way to disable man?
Oh, it seems that the executable in bin is named cperl (not like it's named in-tree).
Btw, commenting out installman fixes the problem and then make install succeeds:
install_all install-all: $(INSTALL_DEPENDENCE) installperl all installman
$(RUN_PERL) installperl --destdir=$(DESTDIR) $(INSTALLFLAGS) $(STRIPFLAGS)
#$(RUN_PERL) installman --destdir=$(DESTDIR)
-@test ! -s extras.lst || PATH="`pwd`:${PATH}" PERL5LIB="`pwd`/lib" $(RUN_PERL) -MCPAN -e '@ARGV&&install(@ARGV)' `cat extras.lst`
The cperl vs perl exe name is expected. It is designed to co-exist with an existing perl5.
The installman failures could be another WSL thing. Nobody ever tried that before.
I ran perlcc on tlmgr, it generated tlmgr.c, but also an error :) I filed that issue in https://github.com/rurban/perl-compiler/issues/434
I also renamed this issue to reflect the remaining issues
@rurban https://github.com/perl11/cperl/commit/2506c06030b8dfeb548757e92c558a01fcd53c9b does not help, it still removes the Makefile (just tried it out)
Here's output of Configure:
