Compile perl with custom compiler path, perlbrew solution preferred

bliako has asked for the wisdom of the Perl Monks concerning the following question:

Dear Monkees!

I need to compile perl from source with custom compiler living in /usr/local/gcc82 (with subdirs bin, include, lib etc.). The reason is that I am embedding CUDA code (which is C) via Inline::C which needs this specific compiler. And XS code must be compiled with same compiler as its perl. (Indeed I get segmentation fault when doing otherwise). So I need perl compiled with this specific compiler and I am doing this on Linux.

I prefer to let perlbrew do the compilation and installation. Is there a simple way to do it? Alternatively, I need to do it manually.

When doing this from vanilla source via hand you'd just pass `-Dcc=/usr/local/gcc82/bin/gcc` yadda yadda yadda. It looks like (cribbing from this SO answer) there's an `PERLBREW_CONFIGURE_FLAGS` environment variable you could add those settings to when you run `perlbrew` and that might do it. The cake is a lie. The cake is a lie. The cake is a lie.	[reply] [d/l] [select]

thank you. It worked as expected. It was prompting me to answer many questions and did not use the sane defaults as usual, I guess the presence of the FLAGS triggers this behaviour. I had to add `-d` to the FLAGS. And because another such perl existed, I also had to give it a different name: `PERLBREW_CONFIGURE_FLAGS='-d -Dcc=/usr/local/gcc82/bin/gcc' perlbrew i +nstall 5.38.2 --as 5.38.2.gcc82` [download] And I can confirm that any C code embedded via Inline::C is compiled with the expected compiler.

I am embedding CUDA code Sounds very interesting. Any chance we can look forward to a writeup/miniguide in CUFP? PerlMonks XP is useless? Not anymore: XPD - Do more with your PerlMonks XP Also check out my sisters artwork and my rather simple sketches/one-panel comics	[reply]

hi cavac. i have already posted something here Inline::CUDA : looking for feedback, 2 years ago. kcott++ kindly tested it. There's uptodate but still experimental code at https://github.com/hadjiprocopis/perl-inline-cuda. It works on my linux system with legacy nvidia gpu. Iam looking for people to test it on their systems (not windows as it stands). If you are less overworked these days, give it a try, provided you have a cuda enabled gpu. bw, bliako	[reply]
