From 04e3dae4adbfd5a69595e17d9f437a60c64a7811 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Mon, 28 Feb 2011 16:17:04 +0000 Subject: [PATCH] mklibs: properly fix library linking - the relinking in some instances used static libraries instead of shared ones with the same name, that led to some nasty symbol conflicts and pic issues. fix this by always using the full path to the libraries and also fix the libc vs libpthread linking order SVN-Revision: 25793 --- .../patches/009-uclibc_libgcc_link.patch | 40 +++++++++++-------- 1 file changed, 24 insertions(+), 16 deletions(-) diff --git a/tools/mklibs/patches/009-uclibc_libgcc_link.patch b/tools/mklibs/patches/009-uclibc_libgcc_link.patch index d5e94068d38..d201821fc6b 100644 --- a/tools/mklibs/patches/009-uclibc_libgcc_link.patch +++ b/tools/mklibs/patches/009-uclibc_libgcc_link.patch @@ -1,30 +1,38 @@ --- a/src/mklibs.py +++ b/src/mklibs.py -@@ -560,6 +560,7 @@ while 1: +@@ -112,11 +112,8 @@ def library_depends_gcc_libnames(obj, so + ret = [] + for i in libs: + match = re.match("^(((?Pld\S*)|(lib(?P\S+))))\.so.*$", i) +- if match and not soname in ("libpthread.so.0"): +- if match.group('ld'): +- ret.append(find_lib(match.group(0))) +- elif match.group('lib'): +- ret.append('-l%s' % match.group('lib')) ++ if match: ++ ret.append(find_lib(match.group(0))) + return ' '.join(ret) + + class Symbol(object): +@@ -560,6 +557,7 @@ while 1: extra_flags = [] extra_pre_obj = [] extra_post_obj = [] -+ libgcc_link = "-lgcc" ++ libgcc_link = find_lib("libgcc_s.so.1") symbols.update(library_symbols_used[library]) -@@ -575,6 +576,10 @@ while 1: - symbols.add(ProvidedSymbol('__uClibc_init', None, None, True)) - symbols.add(ProvidedSymbol('__uClibc_fini', None, None, True)) - extra_flags.append("-Wl,-init,__uClibc_init") -+ libgcc_link = "-lgcc_s_pic" -+ -+ if soname in ("libm.so.0"): -+ libgcc_link = "-lgcc_s_pic" - - map_file = find_pic_map(library) - if map_file: -@@ -590,7 +595,7 @@ while 1: +@@ -590,9 +588,11 @@ while 1: cmd.append(pic_file) cmd.extend(extra_post_obj) cmd.extend(extra_flags) - cmd.append("-lgcc") -+ cmd.append(libgcc_link) cmd.extend(["-L%s" % a for a in [dest_path] + [sysroot + b for b in lib_path if sysroot == "" or b not in ("/" + libdir + "/", "/usr/" + libdir + "/")]]) - cmd.append(library_depends_gcc_libnames(so_file, soname)) +- cmd.append(library_depends_gcc_libnames(so_file, soname)) ++ if soname != "libgcc_s.so.1" and soname != "libc.so.0": ++ cmd.append(library_depends_gcc_libnames(so_file, soname)) ++ if soname != "libgcc_s.so.1": ++ cmd.append(libgcc_link) command(target + "gcc", *cmd) + + ## DEBUG -- 2.30.2
