dev-libs/pth-2.0.7-r3 fails to build on my Toshiba AC100 armv7a-hardfloat-linux-gnueabi Adding -DJB_SP=8 -DJB_PC=9 to CFLAGS/CXXFLAGS fixes this problem. Reproducible: Always Steps to Reproduce: 1. emerge pth Actual Results: pth_mctx.c: In function '__pth_mctx_set': pth_mctx.c:480:2: error: #error "Unsupported Linux (g)libc version and/or platform" Expected Results: Builds correctly
1) Please post your `emerge --info' output in a comment. 2) Please attach the entire build log to this bug report.

I can confirm the same results with a Pandaboard. The arch is the same and so is the glibc version. I can post a build log and emerge --info as well if you would like. I'm currently doing an emerge --emptytree on my system after an issue with GCC. See this post for further details on that issue: https://forums.gentoo.org/viewtopic-t-897674.html. Anyway, I've decided to do an emerge --emptytree even if it is overkill and I've encountered the error mentioned during compilation. There's also this forum post regarding this issue. It's related to uClibc rather than Glibc though: http://forums.gentoo.org/viewtopic-t-685499-start-0.html

https://bugzilla.redhat.com/show_bug.cgi?id=744740 Seems to be an issue with the 3.x kernel version on some architectures. Quotes: ------------------- Let me save you a headache: the (obscure) problem here is that it doesn't like Linux 3.x as a build host. aclocal.m4 does: case $PLATFORM in *-*-linux* ) braindead=no case "x`uname -r`" in changequote(, )dnl x2.[23456789]* ) ;; changequote([, ]) * ) braindead=yes ;; it therefore thinks Linux 3.x is braindead, which is the first issue that leads to the above compile error. ------------------- and ------------------- Looking closer, this bug will only affect architectures that do not have the MCSC method. x86/x86_64 has that method, ARM falls back on SJLJ, and it is in the SJLJ code where braindeath occurs :) ------------------- So if I understand it correctly, changing x2.[23456789]* ) ;; to x[23].[23456789]* ) ;; should solve the issue. I think it would have to be added as a patch because upstream seems to be not responding. (according to the comment in the Redhat Bugzilla)
I couldn't get it to compile even when removing the whole mentioned case block from aclocal.m4 that evaluates braindead to yes. Actually the only (non-obscure) program requiring pth I can see so far seems to be gnupg which just recently switched over to nPth, see here: http://old.nabble.com/GnuPG-master-migrated-to-nPth-to33202006.html -------------------------------- Hi, I merged the npth branch of GnuPG into master. Thus there is no more need for GNU Pth. The drawback is that you need to build and install the replacement library nPth. There are no tarballs yet, thus you need to get that library from its GIT repo: git clone git://git.gnupg.org/npth.git you will also need the latest version of libassuan: git clone git://git.gnupg.org/libassuan.git Q: What is nPth? A: nPth - The New GNU Portable Threads Library This is a library to provide the GNU Pth API and thus a non-preemptive threads implementation. In contrast to GNU Pth is is based on the system's standard threads implementation. This allows the use of libraries which are not compatible to GNU Pth. Experience with a Windows Pth emulation showed that this is a solid way to provide a co-routine based framework. Q: For what system is nPth available? A: As of now nPth provides support for pthread based systems and Windows. Support for other threading implementations is not planned, but can be done. The only tested platforms are GNU/Linux systems; it has not yet been tested on *BSD systems. The support for Windows is implemented but not well tested. nPth is a small library and easy to port to other systems. Q: Why did you drop GNU Pth? A: Almost all systems these days have reliable native thread support thus we should make use of it. We did it for Windows anyway (via our w32pth). The use of GNU Pth is troublesome if you need to link to libraries which require pthread. There are also some problems with GNU Pth on certain systems (iirc, HP/UX). Further, GNU Pth is not anymore used by many projects. Debian Sid lists only zhcon (Fast console CJK system using FrameBuffer) as another user of it. -------------------------------- So it might actually make sense to let pth die and try to get nPth and the gnupg version depending on it into the tree as soon as possible.
