Sorry I visited ELCE 2016 in Berlin, so I had no time to give you the required information. I will sent you buildroot instructions later. If you want you can try it with my embedded-test script (you need mksh and qemu installed): git clone git://git.embedded-test.org/git/embedded-test cd embedded-test git clone git://git.uclibc-ng.org/git/uclibc-ng mksh embedded-test.sh --arch=mipsel --libc=uclibc-ng \ --libc-source=uclibc-ng --test=libc Only 3 tests should fail. Then apply your patch and run it again, it will automatically do a complete clean build. best regards Waldemar _______________________________________________ devel mailing list devel@uclibc-ng.org http://mailman.uclibc-ng.org/cgi-bin/mailman/listinfo/devel
