1.0.6 released
by Waldemar Brodkorb 22 Aug '15

22 Aug '15

Hi, freely after the motto "release early, release often" I decided to make a release today. We now have support for mkstemps, mkstemps64 and mkostemps, mkostemps64 functions, which is required for enlightment software (efl). Furthermore the backward symlinks for gcc to find ld.so are now installed automatically. And as usual bugfixes, mainly found by autobuilders of buildroot project. best regards Waldemar

Links to ld{64,}-uClibc.so.1
by Alexey Brodkin 14 Aug '15

14 Aug '15

Hi Waldemar, I started to play more with uClibc-ng and in particular tried to integrate it in OpenWRT build system. And even thought I got all built from the first attempt on boot kernel reported init failure. Basically it was because missing ld-uClibc.so.0 against which all dynamically linked apps were built. I noticed in Buildroot we cure that manually this way http://git.buildroot.net/buildroot/commit/package/uclibc/uclibc.mk?id=1deb4… But problem with that approach is each and every build system/script will need to care about creation of those links, which is a bit inconvenient. People don't expect that kind of a problem so it will make witch from vanilla uClibc to uClibc-ng not completely painless. So I'm wondering if in uClibc-ng itself we may have creation of corresponding links and later installation of them on target? -Alexey
