Relocatable Rakudo and zef

[hankache]

On Windows 10:

• Built Rakudo 2019.07.1 under C:\rakudo using: perl Configure.pl --backends=moar --gen-moar --moar-option="--cc=gcc" --moar-option="--make=gmake" --relocatable

• Installed zef using: perl6.exe -I. bin\zef install .

• Added both bin and share\perl6\site\bin to the PATH

• Installed a bunch of modules e.g. LWP::Simple

• All works perfectly

• Moved rakudo folder to another location

• Updated the PATH to reflect new location

• zef uninstall LWP::Simple works

• zef nuke LWP::Simple works

• Deleted .zef folder from ~ just in case

• zef install LWP::Simple fails with the following error, it seems it is still trying to look for modules under the previous directory.

PS: This might not be related to zef but it would be great if you can point us in the right direction.
The purpose of this exercise is to create a relocatable Rakudo + Zef + Modules (Rakudo Star) on Windows so that users would be able to install anywhere not only on C:\rakudo

PS2: After running zef uninstall OpenSSL and zef install OpenSSL, zef install LWP::Simple works.
It feels weird since none of them depends on the other!

What do you mean none of them depend on each other? The stack trace quite clearly implicates OpenSSL::NativeLib::dll-resource. And while I don't know why exactly it doesn' work, I can't say I'm surprised to find a compile time variable confused after relocating things it originally referred to

[hankache]

@ugexe What I mean is that based on https://github.com/perl6/perl6-lwp-simple/blob/master/META6.json I don't see any dependency on OpenSSL.
That being said I noticed that one test of LWP::Simple requires IO::Socket::SSL which depends on OpenSSL: https://github.com/perl6/perl6-lwp-simple/blob/eb48ab98b3422b40cd0def8faa882abb9184c265/t/getstore.t#L17

[hankache]

If I understand correctly, you mean to say that OpenSSL::NativeLib::dll-resource still points to the old location?
Where should this be reported, here or in https://github.com/rakudo/rakudo. Or should it not be reported at all and this is how things work?
Thanks

[ugexe]

You could add debug output to the gen-lib -- https://github.com/sergot/openssl/blob/edf86b6dbc7ba6dfc44cdc7e4dd853fc6ca189cb/lib/OpenSSL/NativeLib.pm6#L9-L13 to get a better idea.

What OpenSSL is doing with &gen-lib/resources is a hack, but I don't think it is at fault. The error C:\rakudo\share\perl6\site\dist\BBA6CC2442CDDBD0FD7CC08C7F699CEAFBBA8D56: No such file or directory also doesn't make sense to me given the backtrace (I would have expected ...\site\resources\... not ...\site\dist\...)
