Dear guix,

openssl can be cross-compiled to mingw, by adding a mingw entry in the
list of known openssl targets.

What do you think?

Best regards,

Vivien

Use the target predicates from (guix utils)
(address . 56505@debbugs.gnu.org)
70b76f171502fc7122dbfd120093660616632980.camel@planete-kraus.eu
Dear guix,

antipode on #guix told me that these archaic tests to determine the
openssl target should be replaced with the new target predicates in
(guix utils), and that the kernel and the architecture should be dealt
with independently.

However, it seems that mingw targets do not use the same scheme, so I
had to keep that special case.

I had to introduce a new predicate for mips64el. As far as I
understand, this is also a 64-bit target, so it should also be detected
by target-64bit?, but fortunately this is already the case, so I don’t
have to change target-64bit?. I don’t think there are other predicates
that I should change, but I may be wrong.

What do you think?

Best regards,

Vivien

Added a commit log to this one and committed, thanks!

‘guix build openssl --target=x86_64-w64-mingw32’ works and the funny
part is that .dll files end up in bin/, but I think that’s intended on
Windows?

That’s right. Windows does not have shared objects, and DLLs are not.
You cannot use the compiler to link to a DLL as far as I understand, so
you wouldn’t put them in lib. What you have in lib are the so-called
"import libraries" (.dll.a). These are static libraries that pretend to
provide the functionality, but in fact open the DLL at run-time to
fetch the library implementation from the DLL. So DLLs are kind of
resources.

Anyway, you see that in lib/ you have all the .dll.a files… Oops… I may
have forgotten to check this… This is not a huge problem, because all
outputs would be available when building a dependent package, but it’s
still not right I think.

Now, the .dll.a files are smaller than the static libraries, but not
that small. I don’t know why exactly.

Should I open a new issue with this patch, or is it somehow possible to
continue the discussion here?

Best regards,

Vivien
