sys-devel/crossdev-20151026-r1 fails to setup the stage2 cross-compiler properly Reproducible: Always Steps to Reproduce: 1. build a -s4 cross uclibc toolchain 2. Note that cross-compiling/cross-emerging c++ code fails Actual Results: Incomplete setup of stage2 cross compiler Expected Results: Complete setup of the stage2 cross compiler Possibly a missing call to gcc-config from crossdev after the stage2 merge.
Created attachment 435144 [details] build.log x-emerge failure because of incomplete toolchain setup
As can be easily seen, the build uses the host's c++ compiler (g++) instead of the cross-compiler x86_64-pc-linux-uclibc-g++. The reason is simple, it does not get detected: checking for x86_64-pc-linux-uclibc-gcc... (cached) x86_64-pc-linux-uclibc-gcc checking whether we are using the GNU C compiler... (cached) yes checking whether x86_64-pc-linux-uclibc-gcc accepts -g... (cached) yes checking for x86_64-pc-linux-uclibc-gcc option to accept ISO C89... (cached) none needed checking for x86_64-pc-linux-uclibc-g++... no The reason why it does not get detected is quite simple aswell, there's a missing symlink. Running gcc-config -l and then gcc-config <#> to select the cross-compiler will fix the missing symlinks, this is is what's present after crossdev merged the stage2 compiler: lrwxrwxrwx 1 root root 49

Those should really be created when the stage2 compiler gets merged.
provide the full build log of your uclibc. considering your last bug showed you changing config options, i wouldn't be surprised if this was related.
How would I grab the complete build.log? The build logs do get deleted after a successfull merge, don't they?

As can easily be observed (gcc-stage2 log): >>> Installing (1 of 1) cross-x86_64-pc-linux-uclibc/gcc-5.3.0::local-crossdev * The current gcc config appears valid, so it will not be * automatically switched for you. If you would like to * switch to the newly installed gcc version, do the * following: * gcc-config x86_64-pc-linux-uclibc-5.3.0 * source /etc/profile * Python seems to be broken, attempting to locate CHOST ourselves ... * Switching native-compiler to x86_64-pc-linux-gnu-5.3.0 ...PORTAGE_BZIP2_COMMAND setting is invalid: 'bzip2' PORTAGE_BZIP2_COMMAND setting from make.globals is invalid: 'bzip2' >>> Regenerating /etc/ld.so.cache... So yes, gcc-config does get called as expected (my fault) but it does fail to do it's job. Since I am not a gentoo dev, I can however not tell if it's crossdev's or portage's fault or a bug withing gcc-config.
However right after crossdev finishes it's job: # gcc-config -l [1] x86_64-pc-linux-gnu-4.9.3 [2] x86_64-pc-linux-gnu-5.3.0 * [3] x86_64-pc-linux-uclibc-5.3.0 * [4] x86_64-stamina-linux-musl-5.3.0 * # gcc-config 4 * Switching cross-compiler to x86_64-stamina-linux-musl-5.3.0 ... [ ok ] Seems to work without any problems.

Sorry, wrong number, but running gcc-config 3 does indeed work without an error message aswell (and creates the links)
