uClibc-ng - small C library for embedded systems branch master updated. v1.0.12-8-g0c811db

by wbx＠helium.waldemar-brodkorb.de

This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "uClibc-ng - small C library for embedded systems". The branch, master has been updated via 0c811db32b27ad051beac648fa9676358921f468 (commit) via abfbe76cb5adff2e7c9ddd4dc10c3dcc641d8949 (commit) from 337531c6d5d2b3f04711933ac12432c1fa3f3254 (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- commit 0c811db32b27ad051beac648fa9676358921f468 Author: Waldemar Brodkorb <wbx(a)openadk.org> Date: Fri Feb 19 19:24:36 2016 +0100 mark a.out support as not available Some architectures do not provide the Linux header, so packages which include a.out.h might fail.

[uclibc-ng] Fail to build [libc/inet/if_index.os] when building uClibc-ng 1.0.12 with 2.6.22.19 kernel headers

by Alex Potapenko

Hi, I need to build a mipsel toolchain with pretty old kernel headers (2.6.22.19: http://wl500g.googlecode.com/files/linux-2.6.22.19.tar.bz2). This leads to an error, very similar to the one described here: https://bugs.busybox.net/show_bug.cgi?id=6278 (see exact output in error.log attached). I think this is a kernel bug, but I do need a 2.6.22 toolchain for better mipsel routers support (many of them, like Asus ones, run 2.6.22.19 kernels, and using a toolchain with newer kernel headers has proved to cause numerous issues). Is there a possible workaround for this issue? Thanks, Alex Potapenko

rework of branches

by Waldemar Brodkorb

Hi, to be a little bit clearer with the branches I renamed them: master - current stable development, next release will build from it (old 1.0 branch) devel-old - old master experimental branch, will be removed later and new feature branches will be created (old master branch) uclibc - old uclibc master (old upstream branch) best regards Waldemar
