Hi- It seems that sdcc 2.9.0 will not compile against glibc 2.10.1 due to the lack of a libcmd (which sdcc 2.8.0 didn't need). I'm trying to figure out how to customize the ebuild or supply a patch without deviating too far from what upstream intends for this package. If anyone has an idea or a suggestion for a ebuild/patch I'd be very appreciative. -Robin K.

Created attachment 198616 [details, diff] Build patch for sdcc-2.9.0 to build with glibc-2.10.1. Try adding the attached patch to the epatch in the ebuild. It builds and work for me. # Fix automagic C{,XX}FLAGS epatch "${FILESDIR}"/sdcc-2.8.0-flags.patch epatch "${FILESDIR}"/${P}.patch Don't know if the flag patch is needed.

Hi- I've tested the patch and the build still fails as it's trying to link against -lcmd and failing. I do not have a libcmd anywhere on my system and looking at systems with older versions of glibc it is glibc that seems to have the libcmd library. If I'm missing something let me know. This was a compile attempt against glibc 2.11(.0) on a fairly recent and up-to-date Gentoo system (GCC 4.4.3). -Robin K.

I've found a load of patches for debian and fedora for this. See the link from http://packages.debian.org/squeeze/sdcc for debian, or https://bugzilla.redhat.com/show_bug.cgi?id=488217 for fedora. It compiled ok with an ebuild based on the debian changes. I'll try fedora next. I'm still on gcc-4.3.4, but glibc-2.11.1.
Builds fine with the fedora patch too, and as it seems the simpler patch perhaps use that?

The "-lcmd" issue has nothing to do with GLibc or a system-wide libcmd. The libcmd in question actually comes from inside SDCC. The problem is that there's a compile error inside this libcmd which is apparently ignored by the Makefile, and then the attempt to link to said libcmd (which due to the compile error was never created) causes the final error. I just happened to be lucky enough to notice the earlier error! I reported the actual underlying bug here: <https://sourceforge.net/tracker/?func=detail&aid=3038644&group_id=599&atid=300599>. I will attach a copy of the patch file that fixes it here, too. The reason some people see this and others don't is most likely nothing to do with GLibc but rather to do with GCC: the error is a missing #include, and newer versions of GCC are stricter around those than older versions were. I'm running 4.4.
Created attachment 241193 [details, diff] A patch to fix the UCSim compile error under GCC-4.4
Note also that SDCC-2.9.0 requires GPUtils 0.13.7 to compile the PIC16 port's standard library. Bumping GPUtils to 0.13.7 is the subject of bug #275510.
now in the tree ... thanks !
