Hello, while trying to fast refreshing the SD

About last post of https://bugs.gentoo.org/645920 may be wrong?

Apparently work/build/Makefile takes the wrong CXXFLAGS_FOR_BUILD. You can work around it by setting
CFLAGS="$my_build_flags" CXXFLAGS="$my_build_flags" armv7a-hardfloat-linux-gnueabi-emerge gcc
|
I think the work around suggested is not applicable because is for armv7a-hardfloat-linux-gnueabi, and prepending CFLAGS and CXXFLAGS to the emerge command does not help.
More, I did a simple compile test
This are the two compilers available:

midpower4 ~/scripts # g++ -static test.cpp -O2 -pipe -march=armv6j -mfpu=vfp -mfloat-abi=hard -s -o test
g++: error: unrecognized command line option ‘-mfpu=vfp’; did you mean ‘-mcpu=’?
g++: error: unrecognized command line option ‘-mfloat-abi=hard’
|
Don't you think the latter error is similar to the emerge gcc one?
It seems to me that the reason for the bug is the wrong compiler invocation, not the wrong cflags, what do you think? |

What return [/code]
Yes is similar error and seems to not call correct g++. Can help this thread?

Tender,
gcc cross compiles if you only use -O2 --pipe.
This does mean that gcc itself is not built specifically for -march=armv6j -mfpu=vfp -mfloat-abi=hard but it will still produce code that is, when you feed it -march=armv6j -mfpu=vfp -mfloat-abi=hard in use.

Neddy,
great hint, thanks!
I've successfully compiled gcc with:
| Code: |
midpower4 /usr/armv6j-hardfloat-linux-gnueabi # ROOT=$PWD/ CFLAGS="-O2 -pipe" CXXFLAGS="-O2 -pipe" armv6j-hardfloat-linux-gnueabi-emerge gcc
|
also distcc, showed the same error, is compiling now (but I don't know if the remedy is suitable for it)
Two packages still complain:
sys-apps/util-linux
/usr/lib64/libc.a: error adding symbols: File format not recognized
sys-apps/portage
/usr/include/python2.7/pyport.h:895:2: error: #error "LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)."
Do you have any more advice? |
