gcc5 @5.5.0_4 does not build on PPC MacOS X 10.4.11, Tiger with HFSX because of "Bootstrap comparison failure!"

[ballapete (Peter "Pete" Dyballa)]

The build of GCC48 succeeded, but GCC5 fails the same way as versions 6 (#57506) and 7 (#56922):

Someday we'll figure out what is wrong with your setup there...

$ port -v installed gcc5
The following ports are currently installed:
  gcc5 @5.4.0_0 platform='darwin 8' archs='ppc' date='2016-07-28T04:28:30-0700'

I retried to build gcc5, now with apple-gcc42 @5666.3_15+gpl3 (active) platform='darwin 8' archs='ppc' date='2015-07-10T13:06:16+0200' instead of apple-gcc42 @5666.3_15 platform='darwin 8' archs='ppc' date='2018-08-20T17:19:16+0200'. The result was the same, "checksum mismatch". Even this report about a not existing utility was repeated:

the solution to this for Tiger appears to be adding

-with-dwarf2

to the configure flags.

[ballapete (Peter "Pete" Dyballa)]

Here too it's possible that missing disk space caused the failure. If no-one objects: it can be closed. This compiler's time is (almost) used up (I think pdftk needs it, or some version GCC 4.x…).
