I recently got an N810, and decided I should try and setup a Gentoo build environment for it. I found some useful pointers at http://slonopotamus.org/gentoo-on-n8x0 although I didn't follow it to the letter. Notably, I tried out ~arm to see how things worked out and stayed with -Os. I appeared to run into far fewer bugs than the original author, and they were mostly configure failing to run a test because of cross-compilation. One problem I haven't been able to get around, however, is compiling gcc-4.3.3 (and gcc-4.3.3-r1). The error message is below: make[2]: Entering directory `/usr/arm-softfloat-linux-gnueabi/tmp/portage/sys-devel/gcc-4.3.3/work/build/arm-softfloat-linux-gnueabi/libstdc++-v3' make "AR_FLAGS=rc" "CC_FOR_BUILD=gcc" "CC_FOR_TARGET=arm-softfloat-linux-gnueabi-gcc " "CFLAGS=-O2 -g -pipe -

The same if crosscompiling gentoo with tolchain: UCLIBC_CPU=ARM920T crossdev -v -t arm-softfloat-linux-uclibcgnueabi binutils-2.19.1-r1 gcc-4.3.3-r2 linux-headers-2.6.28-r1 uclibc-0.9.30.1-r1 Build toolchain works but crosscompile gcc does not.
vapier, Notice the CHOST.. He is using -uclibcgnueabi vs -uclibceabi
After some debugging, i found the culprit. http://gcc.gnu.org/viewcvs?view=rev&revision=143194
And could by fixed by adding '-nostdinc++' as described in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39238
Created attachment 187319 [details, diff] patch/hack solve this issue for my This is just proposal which works for my. Probably is sufficinet modify only one of Makefile.* or may be this is not proper solution.
gcc-4.4.0 have exactly same issue
Created attachment 229343 [details] hit the same problem while using gcc-4.4.3
I've hit the same issue building gcc-4.4.4; - CHOST=mipsel-unknown-linux-gnu - CBUILD=i686-pc-linux-gnu - CTARGET=mipsel-unknown-linux-gnu (well, actually unset) I think we can rule out it being something specific to ARM as we've seen the issue elsewhere too. I'm giving another build a try with USE=nocxx, as my aim is to produce a gcc that I can use to compile gcc... I can live with a C-only compiler to bootstrap things.
We should get this fixed. regarding having a C compiler to get a local gcc... Well they are thinking about switching to C++ apparently.
the patch is ready for gcc-4.5 now (already in the patchset dir), if http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45094 is confirmed I'd add that and ask for another patchset.
Luca: if you're going to add patches, please clean them up. review: http://dev.gentoo.org/~vapier/clean-patches further, i'm guessing the patch you're referring to is: 94_all_gcc-4.5-pch-nostdinc.patch but this bug and the upstream PR is about gcc-4.3, not 4.5, so where & why is that patch coming from ? who did you ask to add that patch to the patchset and who approved it ?

That should be the upstream bug, I reproduced the problem locally and tested the solution as well. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40974 Sorry for not putting the right reference ^^;
seems to be fixed with newer versions
