uClibc-ng tries to be compatible with GNU libc and defines __GLIBC__ and pretend to be version 2.2. We once changed it to 2.10, but then some hard to fix problems in different software packages (gcc) occured. It would be better if we disable the special GNU libc checks for uClibc-ng here. uClibc-ng implements the required scanf functionality.

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 c0f118c8869b9095612dfcc4a279e957b67a8efa (commit) from 493d0cc28b0d0fa1dc571ffc876b554376ccdd47 (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 c0f118c8869b9095612dfcc4a279e957b67a8efa Author: Waldemar Brodkorb <wbx(a)uclibc-ng.org> Date: Fri Jun 3 17:24:03 2016 +0200 ppc: cleanup unsupported ppc64 code Remove ppc64 bits and bytes, as we don't support ppc64 and it makes the code more readable without the dead code. ----------------------------------------------------------------------- Summary of changes: libc/sysdeps/linux/powerpc/README.bits | 14 -- libc/sysdeps/linux/powerpc/bits/atomic.h | 252 -------------------------- libc/sysdeps/linux/powerpc/bits/mathinline.h | 76 -------- libc/sysdeps/linux/powerpc/bits/setjmp.h | 7 +- libc/sysdeps/linux/powerpc/bits/stat.h | 108 +---------- libc/sysdeps/linux/powerpc/bits/wordsize.h | 7 +- libc/sysdeps/linux/powerpc/jmpbuf-offsets.h | 25 +-- libc/sysdeps/linux/powerpc/powerpc32/sysdep.h | 151 --------------- libc/sysdeps/linux/powerpc/powerpc64/sysdep.h | 243 ------------------------- libc/sysdeps/linux/powerpc/sys/ucontext.h | 78 -------- libc/sysdeps/linux/powerpc/sysdep.h | 104 +++++++++-- 11 files changed, 102 insertions(+), 963 deletions(-) delete mode 100644 libc/sysdeps/linux/powerpc/README.bits delete mode 100644 libc/sysdeps/linux/powerpc/powerpc32/sysdep.h delete mode 100644 libc/sysdeps/linux/powerpc/powerpc64/sysdep.h diff --git a/libc/sysdeps/linux/powerpc/README.bits b/libc/sysdeps/linux/powerpc/README.bits deleted file mode 100644 index c0542e5..0000000 --- a/libc/sysdeps/linux/powerpc/README.bits +++ /dev/null @@ -1,14 +0,0 @@ - -include/bits is mostly the same as glibc-2.2.4.

[PATCH] [v3] linuxthreads.old: Fix segfault when pthread_mutex_unlock() called against unlocked NORMAL mutex.

Currently, targets dependancy list don't include Makefile.in, this leads to incomplete rebuild after target's compiler/linker flags was changed.

[PATCH] ldso/ARC: fix DT_RELACOUNT handling

by Vineet Gupta

From: Cupertino Miranda <cmiranda(a)synopsys.com> Wih new bintuils supporting DT_RELACOUNT, ldso was crashing as it was parsing relocs incorrectly. Apparently that code ran for first time and was never tested.

problem in sscanf with different data type, uint8_t, uint16_t, uint32_t

by ayaka

Hi I meet a problem with sscanf(), I want to use this function to parse string into number. But I found the neither uint16_t nor uint8_t could work with %d. Here is the sample code: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <stdint.h> int main(int argc, char **argv) { uint8_t num1; uint16_t num2; uint32_t num3; sscanf("10", "%d", &num1); sscanf("10", "%d", &num2); sscanf("10", "%d", &num3); printf("input number is %d %d %d\n", num1, num2, num3); return 0; } input number is 0 0 10 But if it is built with glibc at x86_64, the result would be: input number is 0 10 10 I have no idea why the uint8_t doesn't work, but why the uint16_t doesn't work?
