2015-03-12buildsys: create linker script with proper flagsBernhard Reutner-Fischer
We were not passing the correct use-ld and -m{32,64,...} when creating the linker script. Revisit for gold later on anyway. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

41537a770b46f2376e74af58ba4885749339e81e erroneously stripped the top_builddir off the per-directory flag setting which works fine for in-tree builds but is not correct for O= Just use the full path of the target files to apply the flags to fix that thinko.

2012-05-21Revert "Makerules: respect HARDWIRED_ABSPATH in interp.c"Sedat Dilek
This reverts commit 5dffed7dd1a413f3965af702fa7ecd79809d1988. This breaks ldd when HARDWIRED_ABSPATH=n. [1] http://lists.uclibc.org/pipermail/uclibc/2011-March/045048.html From: Timo Teräs <timo.teras@iki.fi> Your commit 5dffed7dd1a413f3965af702fa7ecd79809d1988 removed absolute path from the interpreter binary name embedded in ELF files. This makes ldd seg.fault as it seems to assume absolute paths. gdb sayeth: (gdb) where #0 0x00111ae3 in find_elf_interpreter (ehdr=0xb7a74000) at ../utils/ldd.c:556 #1 0x00111f2a in find_dependencies (filename=0x114910 "/home/fabled/aports/main/libc0.9.32/src/uClibc-0.9.32-rc3/lib/librt.so.0.9.32") at ../utils/ldd.c:676 #2 0x0011228e in main (argc=1, argv=0xbffff6e8) at ../utils/ldd.c:777 (gdb) p tmp tmp = NULL (gdb) p interp_dir $1 = 0x116660 "ld-uClibc.so.0.9.32" [2] http://lists.uclibc.org/pipermail/uclibc/2011-March/045054.html From: Mike Frysinger <vapier@gentoo.org> On Wed, Mar 23, 2011 at 7:18 AM, Peter Mazinger wrote: >> Your commit 5dffed7dd1a413f3965af702fa7ecd79809d1988 removed absolute >> path from the interpreter binary name embedded in ELF files. > > do you consider my patch wrong? yes. the absolute path to the ldso must be encoded in binaries. the point of HARDWIRED_ABSPATH is purely for sysroot/non-sysroot toolchain, and the interp path isnt involved with that. are you sure this even works at runtime ? i'm pretty sure the kernel doesnt do any path lookups on the interp string.

2012-01-15buildsys: fix detection of silent makeMike Frysinger
The MAKEFLAGS variable contains all the flags without the leading dash. From the GNU make manual: This variable is set up automatically by make to contain the flag letters that make received. Thus, if you do ‘make -ks’ then MAKEFLAGS gets the value ‘ks’. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-01-14buildsys: cache build flags in varsMike Frysinger
Running `make clean` atm takes like 20 seconds because every subdir re-evaluates all the toolchain flags. Add some helpers to automate the process of setting up variables to cache the result of tests, as well as the checking of an already set flag. Now `make clean` takes like 2 seconds on my system.

This adds support for a new binary format, DSBT ELF, to the Makefiles.

2010-09-15libubacktrace: Provide uClibc with backtrace functionsSalvatore Cro
A new shared object, libubacktrace.so.0 is added to uClibc to provide backtrace functions to support application self-debugging. This set of functions requires to dynamically load libgcc_s.so so they need to call dlopen/dlsym that are provided by libdl. For this reason they cannot be included into libc.so.0 but are provided by a new library. User application that wants to use backtrace needs to be compiled with -fexceptions option and -rdynamic to get full symbols printed and must be linked against libubacktrace.so Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
