[kencu (Ken)]

I think you're on the right track. When you see errors like this:

/opt/local/include/poppler/Stream.h:463: error: expected `;' before ‘void’
/opt/local/include/poppler/Stream.h:463: error: expected ‘;’ before ‘override’
/opt/local/include/poppler/Stream.h:464: error: expected ‘;’ before ‘override’

you can almost guarantee the compiler is too old, and doesn't speak the current language. So your idea to use something newer, like gcc6, is right on.

The cxx11 1.1 portgroup is currently pretty messed up (i.e. useless) on 10.5 PPC. It has to be fixed to work properly on that system. At present, it will lead you towards installing clang-4.0, and that's a dead end on PPC, as you found out. So for the moment, on PPC, you can delete that I guess.

The real question is why your configure.compiler=macports-gcc-6 was ignored by texlive-bin. It seems to have not seen that at all:

CC='/usr/bin/gcc-4.2'

That should not happen. Maybe delete the cxx11 1.1 portgroup, and try it again, because that should work. Although I see in the textlive-bin Portfile there are some additional unusual shenanigans that could possibly be relevant to this:

# work around bug in texlive makefiles where $OBJC is not recorded
# during configure phase
build.env                   OBJC=${configure.objc} \
                            OBJCFLAGS="${configure.objcflags} [get_canonical_archflags objc]" \
                            OBJCXX=${configure.objcxx}

[ballapete (Peter "Pete" Dyballa)]

On PPC Tiger, Mac OS X 10.4.11, texlive-bin started to build – with GCC 6! Could be the reason is that I did *not* tell "Yes" when port told me that a rev-upgrade was necessary after libpoppler.dylib had changed. Here, on Tiger, I started a new build.

This looks like a bug in port for me. The upgrade of poppler started with the designation of the compiler to be used. Additionally the rev-upgrade does *not* accept this argument, possibly no argument at all.

This is as unsatisfying as is when port thinks, "Ahh, first I have to build this and that, and maybe later, if nothing breaks, then I can build what this bloody wants me to build" and I have given an extra directive. Then this is applied to all builds, particularly those on which *my* build does not depend.

[kencu (Ken)]

That explains it -- the build that ignored the configure.compiler set was not a clean build.

I have something for you to try, it you like. I added the following block to the cxx11 1.1 portgroup on 10.5 PPC, and so far at least, it seems to work well.

In this file:

/opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/_resources/port1.0/group/cxx11-1.1.tcl

add this platform darwin power block in the location noted:

    # see https://trac.macports.org/ticket/53194
    configure.cxx_stdlib macports-libstdc++

    # added for powerpc cxx11 compatability
    platform darwin powerpc {
        puts "Doing PPC c++11 overrides. EXPERIMENTAL."
        puts "Selected c++ library is: "
        puts ${cxx_stdlib}
        compiler.whitelist macports-gcc-6 macports-gcc-5
        universal_variant no
    }

    if { ${os.major} < 13 } {

Note you just need to add the powerpc block - the bits prior and after are to see the correct location.

[ballapete (Peter "Pete" Dyballa)]

Your eMail came just in time! I was starting to upgrade on Leopard. It's strange that I had nothing more to do and port output:

[kencu (Ken)]

The block is meant to force gcc6 to build cxx11 ports on powerpc. It should do so for any ports that have the cxx11 Portgroup 1.1 added. It also uses the gcc4 ABI compatability to make the gcc6-built software compatible with the systems' gcc4-era /usr/lib/libstdc++. It worked great to build a bunch of them for me. Hope it works for you.

In the case just above, either texlive-bin is not in the cxx11 portgroup, or perhaps the build was unclean (partially configured) and needs to be cleaned and built again.

Good luck!

Me, I do not know how to determine whether texlive-bin is in the cxx11 port group. (Or not.) What I do know is that I started with a cleaned texlive-bin.

Is this "in" or out just synonymous for a line

PortGroup       cxx11 1.1

in Portfile or not?

[ballapete (Peter "Pete" Dyballa)]

I can report another error in port… (At least another one.)

My previous attempts were, with the updated cxx11-1.1.tcl file:

port -vd upgrade texlive-basic texlive-bin
port -vd upgrade texlive-basic texlive-bin  configure.compiler=macports-gcc-6
port -vd upgrade texlive-bin

All attempts were failures, GCC 4.2 was used for compilation. So I tried for a final time, before throwing away my PowerBook G4:

port -vd upgrade texlive-bin configure.compiler=macports-gcc-6

This works. Port does not have to compute what comes first and forget the compiler option.

I feel like a Microsoft user.

The requirement for C++11 could be avoided if you don't need dvisvgm, but it would help to understand why configure.compiler is not working as expected.

As for the cxx11 1.1 PortGroup ... maybe you can open a PR?

What is a "PR?" A Public Relation? The last PRinter before the Autobahn? Or what else?

[mojca (Mojca Miklavec)]

I'm sorry, this was for Ken who probably knows what it is: Pull Request.

I only have access to one super slow PPC, but if the patch fixes the problem, it makes perfect sense to add those few additional lines.

[kencu (Ken)]

Mojca, it seems to work reasonably. It just built through texlive-bin and other cxx11 things on my 10.5 machine without intervention, and gcc6 respects the gcc4-abi flag so it should be compatible with the system's libstdc++.

I'm sure there will be failures (gcc6 can't build everything), but this approach should let a number of things work, and save some aggro. I don't see how it can make anything worse for people. If all are in agreement, I can make a PR and we can assess the fallout.

[mojca (Mojca Miklavec)]

Just prepare a PR and check whether there will be some feedback there, in particular from Marcus.

Can you perhaps just delete macports-clang-4.0 from the whitelist instead of creating your own list? I believe that gcc 4.6 should be removed from the list, 4.7 is also slightly on the border case, but that's a different issue.

Universal variant is problematic in either case (also on x86_64) if gcc is being used.

cxx11 1.1 PortGroup: add support for PowerPC

Add support for C++11 on PowerPC using gcc6.
Blacklisting macports-clang-4.0 which doesn't work on PPC yet.

i am having also problem building texlive-bin on leopard 10.5.8 ppc

it happens when doing "sudo port install ffmpeg"

it builds normally on tiger 10.4.x with ffmpeg

on leopard,t though

"sudo port install ffmpeg" leads to

Error: Failed to build texlive-bin: command execution failed

Your fault, failure to build dvisvgm, is described here: #54358. Changing Portfile to add the configure argument --disable-dvisvgm and then build – if needed – dvisvgm separately us one option, another is to use a different compiler for the whole texlive-bin build.

[kencu (Ken)]

In 2b1e49d05cd18b699f4fb1faf0b9f6c4890c3906/macports-ports:

texlive-bin: add cxx11 1.1 PortGroup

fixes build on older systems
still need to specificy clang > 500 however
can delete other compiler blacklisting as that is

now handled by cxx11 1.1 PortGroup
