Bug ID: 80964
Summary: cross-gotools are not executable on host system
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: go
Assignee: ian at airs dot com
Reporter: bernd.edlinger at hotmail dot de
CC: cmang at google dot com
Target Milestone: ---
I don't know if that is a bug or a feature,
but I use a build spec like this one:
../gcc-trunk/configure --prefix=/home/ed/gnu/arm-linux-gnueabihf-linux64
--target=arm-linux-gnueabihf --enable-languages=all --with-arch=armv7-a
--with-tune=cortex-a9 --with-fpu=vfpv3-d16 --with-float=hard
Note: Recently "all" was changed to include go as well.
Everything builds cleanly, except that the executables
bin/arm-linux-gnueabihf-go and bin/arm-linux-gnueabihf-gofmt
are built for the target system and not for the host, as every other
program in the bin folder:
