uchardet has no universal variant on systems where builds happen with MacPorts gcc

[barracuda156]

Oddly, despite I have +universal as a default setting on 10.5.8, uchardet builds as ppc-only.

36-191:~ svacchanda$ port -v installed uchardet
The following ports are currently installed:
  uchardet @0.0.7_0 (active) requested_variants='' platform='darwin 9' archs='ppc' date='2022-01-18T18:46:00+0800'

After I uninstalled it and tried to force universal, it tries to build a number of clangs and llvm versions:

36-191:~ svacchanda$ sudo port -v install uchardet +universal supported_archs="ppc ppc64" build_arch="ppc ppc64"

Multiple ports from xorg-apps depend on uchardet, and subsequently fail to configure, complaining that uchardet doesn't build for ppc+ppc64. As an example:

36-191:~ svacchanda$ sudo port -v install bitmap
--->  Computing dependencies for bitmap...
Error: Cannot install groff for the archs 'ppc ppc64' because

Replying to barracuda156:

Oddly, despite I have +universal as a default setting on 10.5.8, uchardet builds as ppc-only.

36-191:~ svacchanda$ port -v installed uchardet
The following ports are currently installed:
  uchardet @0.0.7_0 (active) requested_variants='' platform='darwin 9' archs='ppc' date='2022-01-18T18:46:00+0800'

uchardet should have a universal variant, but based on the above, you haven't installed it with that variant. Does the variant show up when you run port variants uchardet?

I suspect that perhaps it won't, because this port indicates that it requires C++11, which on PPC means it must build with a newer MacPorts GCC, and only Apple's GCC ever supported building for multiple architectures at the same time. The only way to get universal with MacPorts GCC would be to build for each arch separately, in other words try adding PortGroup muniversal 1.0 after the PortSystem 1.0 line.

36-191:~ svacchanda$ sudo port -v install uchardet +universal supported_archs="ppc ppc64" build_arch="ppc ppc64"

You should not override supported_archs like this on the command line.

For one thing, the uchardet Portfile does not contain any code that limits the supported_archs, so overriding it and restricting it to only ppc ppc64 as you did won't be of any use.

For another, variables you specify on the comand line affect all dependencies as well, resulting in the nonsense you observed next:

--->  Fetching archive for clang_select
--->  clang_select-2.2_0.darwin_9.ppc-ppc64.tbz2 doesn't seem to exist in /opt/local/var/macports/incoming/verified

clang_select is a noarch port, but because you instructed MacPorts that it supports ppc and ppc64, MacPorts is dutifully reinstalling it for ppc ppc64, which will be no different than before since this port does not install architecture-specific files.

It's also invalid to set build_arch to anything other than a single architecture.

36-191:~ svacchanda$ port variants uchardet
uchardet has the variants:
   debug: Enable debug binaries

I suspect that perhaps it won't, because this port indicates that it requires C++11, which on PPC means it must build with a newer MacPorts GCC, and only Apple's GCC ever supported building for multiple architectures at the same time.

It worked!

Thank you, noted.
