x86_64-elf-gcc @6.3.0_0: Port update

[stevecheckoway (Stephen Checkoway)]

This is a request for an update of x86_64-elf-gcc to the latest version. I've attached a diff of the Portfile. Running it as is gives the warnings

and installing gives the warning

Warning: x86_64-elf-gcc installs files outside the common directory structure.

so I think something more needs to be done. The first group of warnings seem to come from the -crossgcc.setup function but otherwise seem harmless (namely the man and info pages seem fine). Fixing the second warning likely involves fixing something upstream (or having a local patch), but I haven't investigated it.

[mf2k (Frank Schima)]

See #53855.

[anatol (Anatol Pomozov)]

x86_64-elf-gcc is a useful tool for cross compilation and it would be great to see it updated to the latest stable version (that is 7.1 at this moment). Would it be possible to bump the package?

[raimue (Rainer Müller)]

The attached patch proposes an update to gcc 7.1.0 and newlib 2.5.0. However, the resulting destroot looks like it will very likely conflict with the native gcc on ${prefix}/lib/libcc1.so. Most probably this needs a patch to move libcc1 to the appropriate subdirectory. Other distributions might already have it, but I have not looked.

Update to 7.1.0.

What directory should those be in? This ​Debian bug looks related, but MacPorts doesn't use a cross-gcc directory.

[stevecheckoway (Stephen Checkoway)]

For what it's worth, the gcc7 port puts its libcc1.so in ${prefix}/lib/gcc7.

[raimue (Rainer Müller)]

How about ${prefix}/lib/gcc/x86_64-elf/, that would avoid the conflicts. Another step would be to fix path references to this file from other binaries or libraries in the installed files, probably using install_name_tool. Maybe it would even be easier to patch the path in gcc Makefiles.

[mojca (Mojca Miklavec)]

Debian puts these files under

/usr/lib/gcc-cross/<triple>/7/libcc1.so

[mojca (Mojca Miklavec)]

Note that on my computer:

> port provides /opt/local/lib/libcc1.0.so
/opt/local/lib/libcc1.0.so is provided by: avr-gcc

In my opinion it makes no sense to wait for another two years to solve the issue before updating the port. Let's update the port and solve this issues independently inside another ticket.

Other than compiler blacklisting issues (which I ignored in other ports) the port could now be as simple as

# -*- coding: utf-8; mode: tcl; tab-width: 4; indent-tabs-mode: nil; c-basic-offset: 4 -*- vim:fenc=utf-8:ft=portfile:et:sw=4:ts=4:sts=4

PortSystem          1.0
PortGroup           crossgcc 1.0
crossgcc.setup      x86_64-elf 7.3.0
crossgcc.setup_libc newlib 3.0.0 

[mojca (Mojca Miklavec)]

Quoting myself from 2 years ago (I just found this on the MinGW-w64 mailing list):

I just wanted to say that I "solved" the problem for now by adding

--disable-libcc1

to the configure flags as suggested on the GCC's IRC channel.

I opened #57153 for tracking this particular problem independently from the update itself.

[stevecheckoway (Stephen Checkoway)]

That seems reasonable to me (although I haven't tested it yet), but is there a reason to go to 7.3 and not 8.2?

[mojca (Mojca Miklavec)]

I don't know, I switched to 7.3 as it seemed safer, but if 8.2 works fine, we could go to 8.2 of course. Feedback welcome.
