revert GLIBC_MINOR bump in uClibc-ng 1.0 branch

by Waldemar Brodkorb

Hi Thomas, Khem, Alexey, recently Khem tried to use systemd with openembedded and uClibc-ng. Most of the needed stuff is ready and will be committed soon. There is one open issue I want to discuss with you. The GLIBC_MINOR bump in commit 4a05ed87ceb946608100642121c32e642b58cd0d is breaking SSP detection in GCC. This was discovered in Buildroot and fixed. It seems there is a major problem to fix it in OpenEmbedded, so Khem is asking for revert of this commit for the next release. What do you think about it? Isn't the boost problem solved anyway in another way? May be we just learned what it means to bump this number and can revert it back to the old value. We should still try to get a patch into gcc to avoid any misdetection regarding SSP for the next major gcc release. Thanks for any opinion, best regards Waldemar

[PATCH] config: allow config to handle longer path names

by Markus Mayer

The current (arbitrary) limit of 128 characters for path names has proven too short for Android builds, as longer path names are used there. Change conf.c, so it can handle path lengths up to PATH_MAX characters.
