Summary Solaris: linker flag "--gc-sections" not supported

Reported 2010-03-23 14:55:42 PDT
When WebKit is being compiled in KDE's kde-qt (qt.gitorious.org/qt/kde-qt), there's a long, long command at the end that calls the linker. The command starts like this: g++ -Wl,--gc-sections -Wl,-R,/export/home/torti/qt/lib -Wl,-R,/export/home/torti/qt/lib -shared -h libQtWebKit.so.4 -o libQtWebKit.so.4.6.0 obj/release/pcre_compile.o obj/release/pcre_exec.o obj/release/pcre_tables.o [...] And linking fails. After removing "--gc-sections" out of the parameter list, the command succeeds. So I guess it's not supported. This issue might be specific to openSolaris/x86 (32bit) with gcc 3.4.3. $ ld --version GNU ld (GNU Binutils) 2.19 Copyright 2007 Free Software Foundation, Inc.

The bug is still present. It's caused by the following line... unix:!mac:*-g++*:QMAKE_LFLAGS += -Wl,--gc-sections ...in the file WebCore/WebCore.pro. Please fix or remove it like in the attached patch file.

As suggested by Konstantin Tokarev on the qt-interest list, -ffunction-sections and -fdata-sections are not relevant anymore without --gc-sections Hence, the following patch might be better --- src/3rdparty/webkit/WebCore/WebCore.pro.orig Thu Sep 15 16:24:13 2011 +++ src/3rdparty/webkit/WebCore/WebCore.pro Thu Sep 15 16:24:44 2011 @@ -88,8 +88,8 @@ QMAKE_PKGCONFIG_REQUIRES = QtCore QtGui QtNetwork } -unix:!mac:*-g++*:QMAKE_CXXFLAGS += -ffunction-sections -fdata-sections -unix:!mac:*-g++*:QMAKE_LFLAGS += -Wl,--gc-sections +unix:!mac:*-g++*:!solaris*:QMAKE_CXXFLAGS += -ffunction-sections -fdata-sections +unix:!mac:*-g++*:!solaris*:QMAKE_LFLAGS += -Wl,--gc-sections linux*-g++*:QMAKE_LFLAGS += $$QMAKE_LFLAGS_NOUNDEF CONFIG(release):!CONFIG(standalone_package) {
