Revert "Makerules: respect HARDWIRED_ABSPATH in interp.c"
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.
