Description fkhp 2013-12-09 11:32:55 UTC

--host=  for configure changed middle way.

the package level configure ran with:  --build=x86_64-pc-linux-gnu --host=armv7a-hardfloat-linux-gnueabi --target=armv7a-hardfloat-linux-gnueabi

the failed 2 components configure ran with:
 --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --target=armv7a-hardfloat-linux-gnueabi

Reproducible: Always

Steps to Reproduce:
all package is the ~ latest as of Dec 9.

1.emerge crossdev
2.USE="-fortran nossp" crossdev -t armv7a-hardfloat-linux-gnueabi
3.emerge-wrapper --init
4.USE="cxx nls nossp nptl openmp" CBUILD=x86_64-pc-linux-gnu CHOST=armv7a-hardfloat-linux-gnueabi ARCH=arm armv7a-hardfloat-linux-gnueabi-emerge -av sys-devel/gcc

Comment 4 fkhp 2013-12-09 11:40:50 UTC

ARCH=arm set in /usr/armv7a-hardfloat-linux-gnueabi/etc/portage/make.conf

seems not have effect for the armv7a-hardfloat-linux-gnueabi-emerge wrapper.

err, what is failing exactly ?  the `crossdev` is working, but when you try to run the `$CTARGET-emerge sys-devel/gcc`, it fails ?

Comment 6 fkhp 2013-12-11 13:56:29 UTC

it is probobly the crossdev wrapper for emerge not work as expected:

1. it seem the wrapper does not use the setting of ARCH,HOST,BUILD defined in the the crossdev default make.conf file.
2. it seem the wrapper does not use the setting of ARCH,HOST,BUILD defined in the  the command line for some components' configure running.

maybe the crossdev wrapper armv7a-hardfloat-linux-gnueabi-emerge not work as expected

you didn't answer my question.  what is failing ?  is it `crossdev` or the `emerge sys-devel/gcc` ?

the following command failed:

USE="cxx nls nossp nptl openmp" CBUILD=x86_64-pc-linux-gnu CHOST=armv7a-hardfloat-linux-gnueabi ARCH=arm armv7a-hardfloat-linux-gnueabi-emerge -av sys-devel/gcc

Comment 10 fkhp 2013-12-12 09:00:59 UTC

"armv7a-hardfloat-linux-gnueabi-emerge -av sys-devel/gcc" failed but no problem with "emerge -av sys-devel/gcc" .

Do you still have this problem with current gcc ?

Comment 12 fkhp 2017-10-21 11:58:51 UTC

no problem now
