When trying to emerge app-cdr/kcdlabel, the compilations fails, perhaps because of problems with kernel includes. Reproducible: Always Steps to Reproduce: 1. emerge app-cdr/kcdlabel 2. 3.

it's a problem in the linux-headers. make sure you've got the latest ones installed.
I just checked, I had the "latest unmasked" one: linux-headers-2.4.21-r1 I upgraded manually to linux-headers-2.4.22 and then to 2.4.23 I still had the same error... I noticed that I had the linux-headers-2.4.19-r1 protected. I unmerged them and reemerged to linux-headers-2.4.21-r1. Still no chance...
i get exactly the same errors. i'm also at Kernel headers: 2.4.21 Kernel sources: vanilla 2.4.22 # emerge info Portage 2.0.50-r1 (default-x86-1.4, gcc-3.3.2, glibc-2.3.2-r9, 2.4.22)
can confirm with linux-headers-2.6.3(-r1) as well. Also have other people around the office with the same problem. Perhaps we need to use *older* headers? As in it worked on some machine somewhere but the person who last tested it used old kernel headers? Or perhaps he used stuff in /usr/src/linux/include?
I'm installing a new gentoo, and I still have this bug. Anything new?
Still a problem for me. 2.6.5-r1 kernel and 2.6.5 headers.
I found that this issue is due to a conflict with ANSI C++ dialect, not actually a kernel headers issue. To get this package to build and install, I researched the g++ syntax and found that the command below worked: CXXFLAGS="$CXXFLAGS -fpermissive" emerge kcdlabel Please note that this could be integrated into the ebuild, which does not specify build-time flags. The ebuild maintainer should address this issue. Additional note - The addition of "-fpermissive" parameter to $CXXFLAGS does not suppress the following warning, which seems to be a problem in the kcdlabel author's C++ code that was causing the ebuild to fail, i.e. see below: cc1plus: warning: "-Wbad-function-cast" is valid for C/ObjC but not for C++ error: ISO C++ forbids braced-groups within expressions
To clarify my prior report, the error that was the actual cause of the failed build for kcdlabel was as follows: error: ISO C++ forbids braced-groups within expressions
There is an interesting discussion about this problem on http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=203303. Daniel Souza
The -fpermissive fix worked for me...
-fpermissive works for me too. Time for flag-o-matic, I think ...
Created attachment 34751 [details] adds the -fpermissive option to CXXFLAGS This updated ebuild adds -fpermissive to the CXXFLAGS
done :)
