I notice the ones that fail in both are marked "warning", whereas the ones
that fail in the failing build aren't; apparently they expect differences
for some files, maybe only on some platforms.

I'm a bit curious why the comparison is successful and the build proceeds when 
the checksum differs like that ...  I'm actually not sure which build attempt 
is the more valid. Perhaps it is supposed to fail, and the error is in the 
build that proceeds?

I assume there are some compiler tests that I could/should run on  gcc6 on SL ? 

the gcc website  suggests this:

make bootstrap
make -k check

Parallel build race condition is the only explanation that was occurring to me.

Weird. Is this on the same exact machine? 

on one hand the checksum differs and it says bootstrap fails.
on the other, the checksum differs and it says comparison sucessful.


No difference in file system / case sensitivitiy?
? race condition involving parallel build threads?
on one hand the checksum differs and it says bootstrap fails.
on the other, the checksum differs and it says comparison sucessful.

I forced another build and it succeeded:

Does anybody want to compare the logs and try to figure out what's different?

"Bootstrap comparison failure" is an error message specific to the GCC build 
system. GCC is a very large and complex piece of software, and I don't 
understand its build system or why this error sometimes happens for some people.

If you are also having problems building other less complex software, like 
dpkg, would you please show us the main.log file from those failures? They may 
be easier to diagnose.

That worked, thanks!

I see that a similar situation applied to gcc49 and dpkg, that I couldn't build 
them for myself with +universal, but pre-built binaries were available without 
it.  That might well apply to the other things that aren't building for me too, 
except they're libraries, and I already have a bunch of dependencies on them in 
place, so that wouldn't be a good idea unless I redid everything without 
universal.

For some reason the 10.6 x86_64 builder didn't build it either so we didn't 
have a gcc6-6.2.0_0.darwin_10.x86_64.tbz2 package. It's not easy to find old

Josh forced a build now, and it built successfully, so if you clean and try 
again, without the universal variant, you'll get the package from us without 
having to compile it yourself.

gcc6 build failed on Snow Leopard

2016-10-13 Thread Richard L. Hamilton
This was a build prerequisite for py27-numpy, so I can't build that either.  It 
failed both with and without +universal (I think I have the latter set as 
default).
