[PATCH] ARC: Enable getpt() support in ARC defconfigs
by Vlad Zakharov 01 Mar '17

01 Mar '17

This commit enables getpt() support in ARC defconfigs as some packages need it. E.g. we need this to be able to build xterm package as it uses getpt(). As an example I can refer to buildroot autobuilds where xterm build is failing when using prebuilt ARC toolchain (which in its turn uses uClibc without getpt() support): http://autobuild.buildroot.net/results/28a/28a92049a6ceef005787c5779f77ecf3… Signed-off-by: Vlad Zakharov <vzakhar(a)synopsys.com> --- extra/Configs/defconfigs/arc/arcv2_defconfig | 1 + extra/Configs/defconfigs/arc/defconfig | 1 + 2 files changed, 2 insertions(+) diff --git a/extra/Configs/defconfigs/arc/arcv2_defconfig b/extra/Configs/defconfigs/arc/arcv2_defconfig index 383861f..a9d9891 100644 --- a/extra/Configs/defconfigs/arc/arcv2_defconfig +++ b/extra/Configs/defconfigs/arc/arcv2_defconfig @@ -16,6 +16,7 @@ UCLIBC_SUSV2_LEGACY=y UCLIBC_SUSV3_LEGACY=y UCLIBC_SUSV4_LEGACY=y UCLIBC_HAS_PROGRAM_INVOCATION_NAME=y +UCLIBC_HAS_GETPT=y UCLIBC_HAS_LIBUTIL=y UCLIBC_HAS_OBSOLETE_BSD_SIGNAL=y UCLIBC_SV4_DEPRECATED=y diff --git a/extra/Configs/defconfigs/arc/defconfig b/extra/Configs/defconfigs/arc/defconfig index d3773aa..9a76e7d 100644 --- a/extra/Configs/defconfigs/arc/defconfig +++ b/extra/Configs/defconfigs/arc/defconfig @@ -15,6 +15,7 @@ UCLIBC_SUSV2_LEGACY=y UCLIBC_SUSV3_LEGACY=y UCLIBC_SUSV4_LEGACY=y UCLIBC_HAS_PROGRAM_INVOCATION_NAME=y +UCLIBC_HAS_GETPT=y UCLIBC_HAS_LIBUTIL=y UCLIBC_HAS_OBSOLETE_BSD_SIGNAL=y UCLIBC_SV4_DEPRECATED=y -- 2.7.4

[PATCH] ARC: Enable XSI math extensions in ARC defconfigs
by Vlad Zakharov 28 Feb '17

28 Feb '17

This commit enables XSI math extensions to the ISO C standard (bessel). We need this to be able to build mpv package as it uses functions from this extensions. As an example I can refer to buildroot autobuilds where mpv build is failing when using prebuilt ARC toolchain (which in its turn uses uClibc without XSI math extensions): http://autobuild.buildroot.net/results/fb6/fb677a917545adee321bdcd2c2519c81… Signed-off-by: Vlad Zakharov <vzakhar(a)synopsys.com> --- extra/Configs/defconfigs/arc/arcv2_defconfig | 1 + extra/Configs/defconfigs/arc/defconfig | 1 + 2 files changed, 2 insertions(+) diff --git a/extra/Configs/defconfigs/arc/arcv2_defconfig b/extra/Configs/defconfigs/arc/arcv2_defconfig index 2d12358..383861f 100644 --- a/extra/Configs/defconfigs/arc/arcv2_defconfig +++ b/extra/Configs/defconfigs/arc/arcv2_defconfig @@ -2,6 +2,7 @@ CONFIG_ARC_CPU_HS=y ARCH_WANTS_LITTLE_ENDIAN=y # UCLIBC_HAS_FPU is not set DO_C99_MATH=y +DO_XSI_MATH=y KERNEL_HEADERS="%KERNEL_HEADERS%" # DOPIC is not set # LDSO_CACHE_SUPPORT is not set diff --git a/extra/Configs/defconfigs/arc/defconfig b/extra/Configs/defconfigs/arc/defconfig index f582eb5..d3773aa 100644 --- a/extra/Configs/defconfigs/arc/defconfig +++ b/extra/Configs/defconfigs/arc/defconfig @@ -1,6 +1,7 @@ ARCH_WANTS_LITTLE_ENDIAN=y # UCLIBC_HAS_FPU is not set DO_C99_MATH=y +DO_XSI_MATH=y KERNEL_HEADERS="%KERNEL_HEADERS%" # DOPIC is not set # LDSO_CACHE_SUPPORT is not set -- 2.7.4

Do not set *memptr to NULL for posix_memalign when fail
by Kito Cheng 26 Feb '17

26 Feb '17

Hi all: uclibc seem will set argument *memptr to NULL when posix_memalign[1] fail, I know it's not specify in most document[1-3], but other libc (newlib, glibc, musl) implementations are not set it to NULL if fail and gcc testsuite have 1 test case for that[7], so how about make uclib consistent to other libc? the patch attached. newlib[4]: int __posix_memalign (void **memptr, size_t alignment, size_t size) { void *mem; /* Test whether the ALIGNMENT argument is valid. It must be a power of two multiple of sizeof (void *). */ if (alignment % sizeof (void *) != 0 || (alignment & (alignment - 1)) != 0) return EINVAL; mem = __libc_memalign (alignment, size); if (mem != NULL) // only set when success { *memptr = mem; return 0; } return ENOMEM; } glibc [5]: int __posix_memalign (void **memptr, size_t alignment, size_t size) { void *mem; /* Test whether the SIZE argument is valid. It must be a power of two multiple of sizeof (void *). */ if (alignment % sizeof (void *) != 0 || !powerof2 (alignment / sizeof (void *)) != 0 || alignment == 0) return EINVAL; /* Call the hook here, so that caller is posix_memalign's caller and not posix_memalign itself. */ void *(*hook) (size_t, size_t, const void *) = force_reg (__memalign_hook); if (__builtin_expect (hook != NULL, 0)) mem = (*hook)(alignment, size, RETURN_ADDRESS (0)); else mem = __libc_memalign (alignment, size); if (mem != NULL) { // only set when success *memptr = mem; return 0; } return ENOMEM; } musl [6]: int posix_memalign(void **res, size_t align, size_t len) { if (align < sizeof(void *)) return EINVAL; void *mem = __memalign(align, len); if (!mem) return errno; *res = mem; // only set when success return 0; } [1] http://man7.org/linux/man-pages/man3/posix_memalign.3.html [2] http://pubs.opengroup.org/onlinepubs/009695399/functions/posix_memalign.html [3] https://linux.die.net/man/3/posix_memalign [4] https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;a=blob;f=newlib/l… [5] https://sourceware.org/git/?p=glibc.git;a=blob;f=malloc/malloc.c;h=48857939… [6] http://git.musl-libc.org/cgit/musl/tree/src/malloc/posix_memalign.c [7] https://github.com/gcc-mirror/gcc/blob/master/gcc/testsuite/gcc.dg/torture/…

1.0.22 + mipsel + 2.6.22.19
by Lance Fredrickson 23 Feb '17

23 Feb '17

I'm experiencing an issue where compiling uclibc-ng-1.0.22 (+latest patches) for mipsel with kernel 2.6.22.19 gives the following error below. I've tried with newer kernel (4.9 using buildroot-2017.02-rc2) which does compile without issue. I also compile armel with kernel 2.6.36.4. Slightly newer kernel, but this configuration is compiling fine too. This issue arises somewhere between 1.0.21 and current HEAD. thanks, Lance CC libc/sysdeps/linux/common/pwritev.os In file included from ./include/sys/syscall.h:33:0, from libc/sysdeps/linux/common/pwritev.c:19: libc/sysdeps/linux/common/pwritev.c: In function 'pwritev': ./include/bits/syscalls-common.h:15:33: error: '__NR_pwritev' undeclared (first use in this function ) # define SYS_ify(syscall_name) (__NR_##syscall_name) ^ ./include/bits/syscalls.h:157:4: note: in definition of macro 'internal_syscall4' : input, "r" (__a0), "r" (__a1), "r" (__a2) \ ^~~~~ ./include/bits/syscalls.h:40:15: note: in expansion of macro 'SYS_ify' "i" (SYS_ify (name)), err, args) ^~~~~~~ ./include/bits/syscalls.h:24:24: note: in expansion of macro 'INTERNAL_SYSCALL' long result_var = INTERNAL_SYSCALL(name, err, nr, args); \ ^~~~~~~~~~~~~~~~ libc/sysdeps/linux/common/pwritev.c:25:10: note: in expansion of macro 'INLINE_SYSCALL' return INLINE_SYSCALL (pwritev, 4, fd, vector, count, offset); ^~~~~~~~~~~~~~ ./include/bits/syscalls-common.h:15:33: note: each undeclared identifier is reported only once for e ach function it appears in # define SYS_ify(syscall_name) (__NR_##syscall_name) ^ ./include/bits/syscalls.h:157:4: note: in definition of macro 'internal_syscall4' : input, "r" (__a0), "r" (__a1), "r" (__a2) \ ^~~~~ ./include/bits/syscalls.h:40:15: note: in expansion of macro 'SYS_ify' "i" (SYS_ify (name)), err, args) ^~~~~~~ ./include/bits/syscalls.h:24:24: note: in expansion of macro 'INTERNAL_SYSCALL' long result_var = INTERNAL_SYSCALL(name, err, nr, args); \ ^~~~~~~~~~~~~~~~ libc/sysdeps/linux/common/pwritev.c:25:10: note: in expansion of macro 'INLINE_SYSCALL' return INLINE_SYSCALL (pwritev, 4, fd, vector, count, offset); ^~~~~~~~~~~~~~ Makerules:369: recipe for target 'libc/sysdeps/linux/common/pwritev.os' failed make[1]: *** [libc/sysdeps/linux/common/pwritev.os] Error 1

new website
by Waldemar Brodkorb 12 Feb '17

12 Feb '17

Hi, I updated the websites for my embedded linux projects today. If you have any issues to access anything, please sent me an email. I got bored by Trac and now static websites generated with hugo, and gogs for wiki/issue/git is in use. The cgit interface and mailman are still the same. I switched to the faster git http backend for cloning via http/https. I moved on to new certbot and all websites are forced to https. Some minor content (C library matric/ Debugging hints will be added soon). Thanks to Simone for my new black labrador logo abstracted from a real photo of my dog. best regards Waldemar

[PATCH] 1.0.{20, 21} cannot be used in external toolchain in buildroot
by Alexey Neyman 05 Feb '17

05 Feb '17

Hi, Buildroot checks for UCLIBC_HAS_LFS feature macro, which was removed in 1.0.20 (making uClibc-ng always support large files). Patch restores this symbol as "always-enabled". Regards, Alexey.
