Since 2.44_01, the behaviour for `check_lib` in their `Makefile.PL` has
been "fixed" to fail when the `assert_lib` function fails to build the
test.
* 2bc1e90c04
Now, this wouldn't be so bad, since it's good to actually test what
stuff is being compiled against.
Except that *something* is wonky with the cross-compilation build-time
Perl.
```
Undefined subroutine &File::Temp::mktemp called at inc/Devel/CheckLib.pm line 236.
```
As far as I know, this is a built-in function from Perl.
* https://perldoc.perl.org/File/Temp.html
Though, something *else* is wrong with `Checklib.pm`. Side-stepping the
issue by (eww) shelling out to `mktemp`, we get these errors:
```

collect2: error: ld returned 1 exit status
Can't link/include C library 'expat.h', 'expat', aborting.
```
Meanwhile, the actual build, while building the library, seemingly has
no issues building using those paths. `¯\_(ツ)_/¯`

Subject: [PATCH] [HACK]: Assumes Expat paths are good.
|
|
|
|
The `check_lib` check fails with the cross-compilation build platform's
|
|
Perl, since apparently `mktemp` is missing...
|
|
|
|
Even then, side-stepping the issue, it seems it is not actually enough
|
|
to work, as the compilation fails.
