Hello, Sorry for the bother but I’ve been struggling with compiling uclibc-ng. All I did was clone; make defconfig; make. I get the following error: CC ldso/ldso/ldso.oS In file included from ./include/bits/posix1_lim.h:152:0, from ./include/limits.h:144, from ./include/sys/param.h:25, from ./ldso/include/ldso.h:43, from ldso/ldso/ldso.c:32: ./include/bits/local_lim.h:38:26: fatal error: linux/limits.h: No such file or directory compilation terminated. Makerules:370: recipe for target 'ldso/ldso/ldso.oS' failed make: *** [ldso/ldso/ldso.oS] Error 1 I’ve tried to remove -nostdinc, the compilation then proceeds but with no success. I also tried to install the following packages: kernel-package, linux-libc-dev, binutils, libc-dev-bin, linux-headers-4.10.0-35 and linux-headers-generic. Can anyone help? Best regards, Daniel Dubinsky

[PATCH 0/4] Use varargs for common syscall() implementation

by Stafford Horne

Hello, This is a followup to the ("f764bcffe" or1k: syscall: Pass arguments on the stack) patch which fixes the issue where the definition of syscall() in unistd.h and the common implementation in uclibc-ng don't match. This series allows the implementation to match the definition and then goes on to remove generic implementations used by or1k, nds32 and arc. -Stafford Stafford Horne (4): syscall: Make common implementation match unistd.h or1k: Use new common syscall() implementation nds32: Use new common syscall() implementation arc: Use new common syscall() implementation libc/sysdeps/linux/arc/Makefile.arch | 2 +- libc/sysdeps/linux/arc/syscall.c | 17 ----------------- libc/sysdeps/linux/common/syscall.c | 18 +++++++++++++++++- libc/sysdeps/linux/nds32/Makefile.arch | 4 ++-- libc/sysdeps/linux/nds32/syscall.c | 28 ---------------------------- libc/sysdeps/linux/or1k/Makefile.arch | 2 +- libc/sysdeps/linux/or1k/syscall.c | 32 -------------------------------- 7 files changed, 21 insertions(+), 82 deletions(-) delete mode 100644 libc/sysdeps/linux/arc/syscall.c delete mode 100644 libc/sysdeps/linux/nds32/syscall.c delete mode 100644 libc/sysdeps/linux/or1k/syscall.c -- 2.13.6

[PATCH] Fix subtle race in tst-cancel2 / tst-cancelx2

by Vineet Gupta

When ran on ARC, these tests would ocassionally fail | [ARCLinux]# for i in 1 2 3 4 5 ; do ./tst-cancel2; echo $?; done | write succeeded | result is wrong: expected 0xffffffff, got 0x1 | 1 <-- fail | 0 <-- pass | 0 <--- pass | 0 <-- pass | write succeeded | result is wrong: expected 0xffffffff, got 0x1 | 1 <-- fail Same test (which originated form glibc) doesn't fail in glibc builds. Turns out there's a subtle race in uclibc version The test creates a new thread, makes it do a looong write call, and parent then cancels the thread, expecting it to unwind out of write call cleanly. However the write (even for 10k bytes) could fnish befor eparent gets a chance ti run and/or cancel - causing the occasional failire.

[PATCH] tst-syscall*: Add tests for syscall() with varargs

by Stafford Horne

Add tests in preparation for genericizing some of the architecture syscall() implementations. This was noticed when testing OR1K and found it had a broken syscall implementation. These tests try to cover the libc syscall() lqyer which has the purpose of passing the syscall number and arguments to the kernel. The actual kernel syscalls chosen have been selected for ease of testing.

Proper test for broken posix_spawn

by Alex Potapenko

Hi Waldemar, I've recently encountered an issue with broken posix_spawn in uClibc-ng 1.0.26, which made cups 2.2.[46] unusable. Looking at commit 71b3a63b641716165f664cf112be0673a122cea0, I see that it should be fixed in 1.0.27. I have a small test code that illustrates the problem with posix_spawn, which works fine with GNU lib C, but fails with uClibc-ng 1.0.26 (see posix_spawn.c attached). If I remove POSIX_SPAWN_SETSIGDEF flag, it works OK. I can't test it with 1.0.27 yet, could you please verify that it works? Also, if it works fine, another question. What is the proper macro test for working posix_spawn (uClibc-ng version 1.0.27+)? Thank you, Alex

uclibc-ng-1.0.27 commit ea38f4d89c96 breaks native build on fenv* bits

by Joshua Kinard

Similar to the thread regarding build failures w/ DO_XSI_MATH disabled, I think there is another breakage with the new FENV bits that were added by commit ea38f4d89c96, which when built natively on an existing uclibc-ng-1.0.26 chroot yield these failures: LD libuClibc-0.1.0.27.so libc/libc_so.a(w_acos.os): In function `__GI_acos': w_acos.c:(.text+0x74): undefined reference to `feraiseexcept' libc/libc_so.a(k_standardl.os): In function `__kernel_standard_l': k_standardl.c:(.text+0x10): undefined reference to `feholdexcept' k_standardl.c:(.text+0x70): undefined reference to `fesetenv' collect2: error: ld returned 1 exit status make: *** [libc/Makefile.in:77: lib/libc.so] Error 1 I am not sure why these symbols go missing. Possibly something related to kernel headers? My chroot environment has kernel headers from 4.13 installed, so I am thinking this isn't the issue. I have both DO_C99_MATH and DO_XSI_MATH enabled, using legacy NAN (not 2008), and various other glibc-compatibility tweaks enabled. uclibc-ng-1.0.26 built fine -- the only real issue there was my previously-reported xfsprogs build failure. I also read earlier that it is considered uncommon to build uclibc-ng natively. I'd like to call that into question and recommend that native builds be tested in some capacity before new releases are made. An existing environment should be capable of upgrading itself. -- Joshua Kinard Gentoo/MIPS kumba(a)gentoo.org 6144R/F5C6C943 2015-04-27 177C 1972 1FB8 F254 BAD0 3E72 5C63 F4E3 F5C6 C943 "The past tempts us, the present confuses us, the future frightens us.
