SOLUTION: How to install Compress::Stream::Zstd in Strawberry Perl?

[cmv]

Monks-

This place is fantastic, as are the people who contribute! No wonder Perl continues to be my preferred language. I just wanted to describe the final solution that I ended up using, for anyone else who need this help.

Shout outs for:

• ++syphilis - Figuring out the MYSIS2 solution, and the zstd-v1.5.7-win64.zip solution
• ++swl - Mentioning Alien::zstd
• ++brian_d_foy - Building Alien::zstd, moving libstd.a & finishing Compress::Stream::Zstd by hand

Ok, here is what worked for me on a Windows 10 box:

1. Install Strawberry Perl following the label directions

2. Startup CPAN shell & install Alien::Zstd

   $ perl -MCPAN -e shell
   cpan> install Alien::Zstd
   

3. Once successfully completed, verify the location of the libzstd.a library that was just built

   c:/Strawberry/perl/site/lib/auto/share/dist/Alien-zstd/lib/libzstd.a
   

4. Back in CPAN shell, try to install Compress::Stream::Zstd (it should fail)

   cpan> install Compress::Stream::Zstd
   ...
   The system cannot find the file specified
   -or-
   Cannot find ext/zstd/lib/libzstd.a: No such file or directory
   -or-
   Something similar
   

5. Figure out where CPAN is building your Compress::Stream::Zstd

   c:/Strawberry/cpan/build/Compress-Stream-Zstd-0.206-0
   

6. Copy the Alien::zstd libzstd.a file to where Compress::Stream::Zstd expects it to be:

   $ copy c:/Strawberry/perl/site/lib/auto/share/dist/Alien-zstd/lib/libz
   +std.a c:/Strawberry/cpan/build/Compress-Stream-Zstd-0.206-0/ext/zstd/
   +lib
   

7. Go to the CPAN build directory for Compress::Stream::Zstd and finish building by hand:

   $ cd c:/Strawberry/cpan/build/Compress-Stream-Zstd-0.206-0
   $ perl ./Build.PL
   $ ./Build
   $ ./Build test
   $ ./Build install
   

8. That should complete successfully, and you are now done!

Good to see it works, and thanks for the set of steps.

In the interests of TIMTOWTDI, steps 4-7 could be simplified using cpanm. Calling cpanm --look opens a shell in the build directory. On Windows it is a cmd chell.

(Untested)

cpanm --look Compress::Stream::Zstd
:: You are now in the build dir

:: This next line prints the location of the Alien::Zstd files, under 
+which will be libzstd.a
perl -MAlien::Zstd -E"say Alien::Zstd->dist_dir"

:: assuming it is in the dir you noted in your post the line would be 
copy c:/Strawberry/perl/site/lib/auto/share/dist/Alien-zstd/lib/libzst
+d.a ext\zstd\lib

:: (One could also use File::Copy to use perl to find and copy the fil
+e in one step)

:: build, test, install
perl .\Build.PL && build && build test && build install

:: back to your previous shell
exit
