When I tried to compile crossdev and used it to compile CXX project i get error (i686-linux-gnu-g++ not found). Native is x86_64. Reproducible: Always Steps to Reproduce: emerge crossdev and try compile CXX project Actual Results: fails wit g++ not found Expected Results: project compiles When i tried recompiling of cross-i686-pc-linux-gnu/gcc i see from output that nocxx flag have changed from enabled to disabled and g++ is now working.
Yes, it seems cross-*/gcc isn't rebuilt with USE=-nocxx. Please post your `emerge --info' too.

The crossdev script adds "-u" to the emerge options. This causes the first pass of cross-gcc to build, and the second pass to get skipped (leaving you without C++ support). My workaround is to edit the script, and remove the "-u" part.
I wonder if this is the proper solution: When asked to emerge -u <installed package>, portage doesn't consider changes in USE flags. So by specifically setting -Nu instead of -u, this should be detected properly.
