From 57b134349f8c8e27117525f220122eea2edbc834 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Mon, 28 Feb 2011 16:17:04 +0000 Subject: 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 git-svn-id: svn://svn.openwrt.org/openwrt/trunk@25793 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- tools/mklibs/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 d5e94068d3..d201821fc6 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 -- cgit v1.2.3
