No log file left…

[ballapete (Peter "Pete" Dyballa)]

Sorry, I thought it was still building libxml2! Before it worked to upgrade to pure libxml2 @2.10.2_1, without variant readline added. Main.log of course exists!

[ballapete (Peter "Pete" Dyballa)]

Main.log from PPC Tiger

I think I first gave this ticket the proper title – because now I cannot install other ports, for example mpack. This fails like this:

So I am going to remove lbzip2 and see what this changes.

[ballapete (Peter "Pete" Dyballa)]

After deactivation of lbzip2 mpack could be installed and port started to install the next port…

[ryandesign (Ryan Carsten Schmidt)]

Ok, so the bug is that your lbzip2 program doesn't work?

[ballapete (Peter "Pete" Dyballa)]

Replying to ryandesign:

Yes, that's my impression.

[ryandesign (Ryan Carsten Schmidt)]

I just installed lbzip2 on a PowerBook running Tiger and MacPorts was able to use it just fine. Does rebuilding lbzip2 help? If not, can you get any other information about how lbzip2 is failing?

sudo port clean lbzip2
sudo port -ns upgrade --force lbzip2

[ryandesign (Ryan Carsten Schmidt)]

Excuse me! On my PowerBook MacPorts was able to use lbzip2 to decompress a source tarball, but when MacPorts tried to use lbzip2 to compress an archive, it failed for me as it did for you:

lbzip2: WORKER-THREADS not set, specify "-h" for help

According to ​the source code, this message is only emitted if _SC_NPROCESSORS_ONLN is not defined, which is indeed the case on Tiger; it was introduced in Leopard.

MacPorts legacy support has an implementation of sysconf that supports _SC_NPROCESSORS_ONLN on Tiger, and including that in the port fixes it for me, so I'll commit that along with the required revbump shortly.

Replying to ryandesign:

Excuse me! On my PowerBook MacPorts was able to use lbzip2 to decompress a source tarball,

Excuse me again! Decompressing didn't work either, prior to the fix.

lbzip2: Use legacysupport for _SC_NPROCESSORS_ONLN

Closes: #65878

[ballapete (Peter "Pete" Dyballa)]

lbzip2 built, the tests succeeded, and port could upgrade a first software, expat.
