Hi, I'm in the process of building a mipsel feed for Optware-ng using uClibc-ng 1.0.6 and gcc-4.9.3 toolchain built using Buildroot. The first issue I stumbled upon was when I tried to build gettext 0.9.14: libtool: link: /home/alex/optware/buildroot-mipsel-ng/toolchain/buildroot-mipsel-linux-2.6.36-uclibc-ng-4.9.3/bin/mipsel-buildroot-linux-uclibc-gcc -std=gnu99 -g -O2 -Wl,--dynamic-linker=/opt/lib/ld-uClibc.so.0 -Wl,-rpath -Wl,/opt/lib -Wl,-rpath-link -Wl,/home/alex/optware/buildroot-mipsel-ng/staging/opt/lib -o .libs/msgcmp msgcmp-msgcmp.o msgcmp-msgl-fsearch.o -L/home/alex/optware/buildroot-mipsel-ng/staging/opt/lib ./.libs/libgettextsrc.so /home/alex/optware/buildroot-mipsel-ng/builds/gettext/gettext-tools/gnulib-lib/.libs/libgettextlib.so -lncurses /home/alex/optware/buildroot-mipsel-ng/builds/gettext/gettext-tools/intl/.libs/libintl.so -lc -liconv -lm -Wl,-rpath -Wl,/opt/lib /home/alex/optware/buildroot-mipsel-ng/builds/gettext/gettext-tools/gnulib-lib/.libs/libgettextlib.so: undefined reference to `posix_spawn_file_actions_addclose' /home/alex/optware/buildroot-mipsel-ng/builds/gettext/gettext-tools/gnulib-lib/.libs/libgettextlib.so: undefined reference to `posix_spawnp' /home/alex/optware/buildroot-mipsel-ng/builds/gettext/gettext-tools/gnulib-lib/.libs/libgettextlib.so: undefined reference to `posix_spawn_file_actions_adddup2' /home/alex/optware/buildroot-mipsel-ng/builds/gettext/gettext-tools/gnulib-lib/.libs/libgettextlib.so: undefined reference to `posix_spawn_file_actions_addopen' collect2: error: ld returned 1 exit status The same gettext version builds fine against uclibc-0.9.33.2 with this patch: https://github.com/alllexx88/Optware-ng/blob/master/sources/gettext/uClibc-… I take it, those symbols are there in the headers, but not yet implemented un uclibc-ng. I can't see from the first glance any configure switch to disable the use of those symbols, will look further into the sourcecode a bit later, maybe there's a simple workaround to not use them. -- Best regards, Alex Potapenko

Buildroot uClibc 0.9.33.2 and uClibc-ng 1.0.6 compatibility?
by Alex Potapenko 27 Aug '15

27 Aug '15

Dear all, I'm developer of Optware-ng <https://github.com/alllexx88/Optware-ng>, an attempt to "revive" the obsolete Optware. All three feeds currently use Buildroot 2015-02 toolchains, two of them (arm and mipsel) use uClibc 0.9.33.2 as the libc. These uClibc targets (especially mipsel) have some hard-to-debug issues that are quite possible due to uClibc-0.9.33.2 bugs (glibc target has no such problems), so I'm thinking to switch to uClibc-ng using the latest Buildroot. The question is whether Buildroot-2015-02's uClibc 0.9.33.2 and uClibc-ng 1.0.6 are compatible? Can I simply compile new toolchain and re-package the libc, or do I need to recompile the entire repos from scratch? -- Best regards, Alex Potapenko

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
