#52161 new defect

mp-buildbot: incorrect error message when a port cannot be installed due to arch mismatch

Reported by: ryandesign (Ryan Schmidt) Owned by: macports-tickets@…

Description

If I try to install wine on PowerPC, it fails, as it should:

# /opt/local/bin/port install wine
Error: wine cannot be installed for the configured build_arch 'ppc' because it only supports the arch(s) 'i386'.
To report a bug, follow the instructions in the guide:
    http://guide.macports.org/#project.tickets
Error: Processing of port wine failed

However, when the buildbot tries to install dependencies of wine, using dependencies.tcl, it fails with a weirder error:

Error: Cannot install wine for the arch(s) 'powerpc' because
Error: its dependency bison does not build for the required arch(s) by default
Error: and the configured universal_archs 'i386 ppc' are not sufficient.
architecture mismatch
    while executing
"mportdepends $mport "activate""
    invoked from within
"if {[mportdepends $mport "activate"] != 0} {
    ui_error "mportdepends $portname activate failed."
    exit 1
}"
    (file "/opt/bblocal/var/buildworker/ports/build/mpbb/tools/dependencies.tcl" line 74)

It should fail, of course, but the reason given for the failure is wrong.

  1. "powerpc" is not a valid build architecture. It's a valid system architecture—a valid value for ${os.arch}—but not a valid ${build_arch}.
  2. The problem is not that wine's dependencies can't be built on this system. The problem is that wine itself can't be built on this system.

I didn't see any architecture-related code in dependencies.tcl, so this might actually be a base bug.

Here's a weirder one:

Actually, it cannot install svn2git for ppc because its dependency qt5-qtbase only builds for x86_64.

Replying to ryandesign:

Actually, it cannot install svn2git for ppc because its dependency qt5-qtbase only builds for x86_64.

Not sure if anything changed since you wrote this, but currently svn2git includes the qmake5 portgroup which in turn includes the qt5 portgroup, which sets supported_archs.

Basically the issue here is that check_supported_archs (which produces the error seen in the wine example) is only called when you execute a target on the port. The incorrect error being seen here is generated during dependency calculation, before any targets are run. The reason for the ppc/powerpc mismatch is that unsupported archs are filtered out of configure.build_arch, which in this case leaves it empty. So get_canonical_archs falls back to returning ${os.arch} rather than return an empty string.
