The following is a set of running notes that I made as I worked through this.

I checked through Makefile.PL: I had all prerequisites except for two. Math::Matrix installed without a hitch. The other, Test::CheckManifest, had a problem:

Running make test for RENEEB/Test-CheckManifest-1.42.tar.gz PERL_DL_NONLAZY=1 "/home/ken/perl5/perlbrew/perls/perl-5.34.0/bin/perl +.exe" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test:: +Harness::Switches; test_harness(0, 'blib/lib', 'blib/arch')" t/*.t t/ +extra/*.t t/xt/*.t t/00_load.t ........................ ok Bailout called. Further testing stopped: Cannot find a MANIFEST. Ple +ase check! FAILED--Further testing stopped: Cannot find a MANIFEST. Please check! make: *** [Makefile:874: test_dynamic] Error 255 (/usr/bin/make test exited with 512)

I've encountered that problem on a variety of platforms over a number of years. There was a report about this in rt-cpan; the tracker has been moved to github and I can't find the report. However, I do recall that discussions in that report lead to this in the doco: "Test::CheckManifest - REPLACE THIS MODULE". I've been using ExtUtils::Manifest ever since (for both personal and $work modules) without any problems. Also, ExtUtils::Manifest is a core module, so no CPAN installation necessary. You may want to consider making this change too. Anyway, I force-installed Test::CheckManifest to avoid problems with prerequisite testing: actual tests using this may still fail, but I'll worry about that down the track.

[On a side note, modules such as Test::Pod and Test::CheckManifest should be for "Author Only" tests. They are typically skipped unless something like $ENV{RELEASE_TESTING} has a true value. I question their inclusion under PREREQ_PM in Makefile.PL.]

I manually made the changes you indicated for lib/Inline/ (from new code in github). Unfortunately, that didn't fix my reported problem:

$ perl Makefile.PL Can't exec "/cygdrive/c/Program": No such file or directory at /home/k +en/local/opt/perl/inline_cuda/perl-inline-cuda-master/lib/Inline/CUDA +/ line 182. Inline::CUDA::Utils::find_dependencies (via N/A) : failed to find vers +ion of /cygdrive/c/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v1 +1.4/bin/nvcc with this command: /cygdrive/c/Program Files/NVIDIA GPU +Computing Toolkit/CUDA/v11.4/bin/nvcc --version Makefile.PL : error, call to Inline::CUDA::Utils::find_dependencies() +has failed.

I then made a manual change to Inline::CUDA::Utils::find_dependencies(). At line 181:

#my $cmd = "${aexe} --version"; my $cmd = "\Q${aexe}\E --version";

A Makefile was successfully created:

$ perl Makefile.PL find_dependencies() : report: cc : /usr/bin/cc cxx : /usr/bin/c++ ld : /usr/bin/cc nvcc : /cygdrive/c/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v +11.4/bin/nvcc nvcc-release : 11.4 nvcc-version : V11.4.48 nvlink : /cygdrive/c/Program Files/NVIDIA GPU Computing Toolkit/CUDA +/v11.4/bin/nvlink nvlink-release : 11.4 nvlink-version : V11.4.48 Makefile.PL : configuration written to '/home/ken/local/opt/perl/inlin +e_cuda/perl-inline-cuda-master/config/Inline-CUDA.conf'. Generating a Unix-style Makefile Writing Makefile for Inline::CUDA Writing MYMETA.yml and MYMETA.json

No problems with make:

$ make cp /home/ken/local/opt/perl/inline_cuda/perl-inline-cuda-master/config +/Inline-CUDA.conf blib/lib/auto/share/dist/Inline-CUDA/ +nf cp lib/Inline/CUDA/ blib/lib/Inline/CUDA/ cp lib/Inline/ blib/lib/Inline/ cp scripts/ blib/script/ "/home/ken/perl5/perlbrew/perls/perl-5.34.0/bin/perl.exe" -MExtUtils:: +MY -e 'MY->fixin(shift)' -- blib/script/ Manifying 1 pod document

I did have problems with 'make test'. There was a huge amount of output: too much to post here and I don't have time to look through this closely right now. Some look like previous problems caused by spaces and can probably be just as easily fixed. For instance:

/bin/sh: /cygdrive/c/Program: No such file or directory make[1]: *** [Makefile:352: _011_basic_t_f5ac.o] Error 127

The "Author Tests" were handled as I indicated above, so no issues with my potentially dodgy Test::CheckManifest:

t/manifest.t ....................................... skipped: Author t +ests not required for installation t/pod-coverage.t ................................... skipped: Author t +ests not required for installation t/pod.t ............................................ skipped: Author t +ests not required for installation

This further strengthens my argument for not including those Test::* modules as prerequisites. I also note that Test::Pod::Coverage is not mentioned in Manifest.PL but is used in t/pod-coverage.t.

The final few lines of make test output were:

Files=20, Tests=13, 59 wallclock secs ( 0.03 usr 0.01 sys + 14.46 cus +r 16.56 csys = 31.06 CPU) Result: FAIL Failed 15/20 test programs. 0/13 subtests failed. make: *** [Makefile:926: test_dynamic] Error 255

It's Friday morning in my timezone and I have $work today. I can probably spend more time on this over the weekend.
