icu/source/data/Makefile says:

# NOTE: If you get the error "No rule to make target 'out/build/icudt64l/uprops.icu'",

out OTOH seems to be a directory in icu/source/data which already has an in directory. It is just not built…

Main.log from PPC Leopard

[kencu (Ken)]

I saw that same error several times as well, and then, after another sudo port sync, I got it to build.

$ port -v installed icu
The following ports are currently installed:
  icu @55.1_0 platform='darwin 8' archs='ppc' date='2016-07-20T18:57:38-0700'
  icu @58.2_0 platform='darwin 8' archs='ppc' date='2017-04-14T11:09:01-0700'
  icu @58.2_1 platform='darwin 8' archs='ppc' date='2017-08-12T12:32:47-0700'
  icu @58.2_2 platform='darwin 8' archs='ppc' date='2017-11-04T11:15:48-0700'
  icu @65.1_0 (active) platform='darwin 8' archs='ppc' date='2019-10-20T15:57:20-0700'

I didn't change anything in the portfile, I believe, to make it build, so perhaps try again.

It might also be a parallel building thing -- I've been seeing a lot of issues lately that seem to be related to parallel building on Tiger and Leopard, and so I set my build jobs to 1 in macports.conf on those systems.

I have not prospected why that is occurring, and I most certainly had no intention of posting up a ticket about it until I had it all sorted out, but in the meantime, you might find it helpful to try disabling parallel building as an experiment.

[ballapete (Peter "Pete" Dyballa)]

I too saw different errors before and ran a selfupdate, which gave this error that I reported because a lot of ports depend on icu.

Hmm, how can a single core single thread processor like the PPC 7447A have a problem with parallel building?

[kencu (Ken)]

Replying to ballapete:

Yes, well, you got me there, didn't you :>

I suppose if there is only one core, then parallel building could not be a problem.

Replying to kencu:

And my next build, with buildmakejobs 1, show the same result, that which I reported.

[ballapete (Peter "Pete" Dyballa)]

This little patch allows icu to build!

Patch file to allow icu build on PPC Leopard, Mac OS X 10.5.8

[kencu (Ken)]

that does work, thanks. I'm not exactly sure how I built this before.

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

This issue seems to have shown up on ​other systems.

Although it is probably something upstream should fix, there is a ​pull request that attempts to work around the issue.

'mkdir out'? Or: '+ o u t RET' in dired-mode in GNU Emacs?
