 Posted: Fri Oct 08, 2021 6:29 am Post subject: [SOLVED] Cross-emerge: Is it possible to use an own made gcc |
 |
|
Crossdev and Portage builds compiler and packages in a /usr/CHOST target directory.
Different cross compiler versions can be selected by gcc-config. So far, so good.
But: Is it possible to tell Portage to use an own made cross compiler/linker, which is installed in e. g. /usr/local/ or /opt?
Maybe a cross compiler build bay crosstool-ng or yocto?

jgeiss66 tell us more about what your trying to do.
have you tried out sys-devel/crossdev ?

Yes, thanks, I know crossdev and I am working quite a lot with it.
My special care is, though, different. Some customers give their toolchain, which is made by Yocto, Crosstool-NG, or other and it can be installed in e. g. /opt. It would be nice if Portage could use his toolchain to build a small system, as usual, in /usr/TARGET. |

| Is the cross-compiler in $PATH, and given a standard $CHOST-based name? If so, then regular Portage cross-emerge support should find it and use it without any special overrides. |

Yes, is works. I didn't thought of that.
But you have to make some symbolic links first. Emerge changes PATH, so the compiler cannot be found. I did
| Code: | crossdev --init-target --stable -oS gentoo -oO /var/db/repos/private-overlay --target arm-poky-linux-gnueabi
cd /opt/bin
for f in /usr/local/poky/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi.*; do ln -s "$f" .; done
|
After editing /usr/arm-poky-linux-gnueabi/etc/portage/make.conf to meet my needs, I could emerge glibc and busybox.
| Code: | arm-poky-linux-gnueabi-emerge -av glibc busybox
|
Thank you very much. I can live with that solution. |
