I compiled dia with clang and the gold linker (binutils-config --linker ld.gold), which failed. After setting the binutils back to the bfd linker (binutils-config --linker ld.bfd), it was able to link dia. I did not use any special sort of compiler/linker flags like lto, just march and O2. Here is the last output of the emerge window: /bin/bash ../libtool --tag=CC --mode=link clang -I/usr/include/libxml2 -I/usr/include/freetype2 -march=athlon64-sse3 -O2 -Wall --std=c89 -Wdeclaration-after-statement -Wmissing-prototypes -Wmissing-declarations -finline-functions -fstrict-aliasing -Wpointer-arith -Winit-self -Wformat-nonliteral -export-dynamic -Wl,-O1 -Wl,--as-needed -o dia confirm.o exit_dialog.o diagram.o preferences.o load_save.o properties-dialog.o defaults.o undo.o object_ops.o layer_dialog.o commands.o app_procs.o connectionpoint_ops.o disp_callbacks.o display.o select.o color_area.o linewidth_area.o grid.o handle_ops.o interface.o modify_tool.o scroll_tool.o create_object.o magnify.o menus.o cut_n_paste.o render_gdk.o tool.o diapagelayout.o pagesetup.o filedlg.o find-and-replace.o plugin-manager.o dia-props.o gtkwrapbox.o gtkhwrapbox.o gtkvwrapbox.o cursor.o splash.o recent_files.o diagram_tree.o diagram_tree_window.o diagram_tree_menu.o diagram_tree_menu_callbacks.o sheets.o sheets_dialog.o sheets_dialog_callbacks.o autosave.o dynamic_refresh.o navigation.o diacanvas.o highlight.o textedit.o textedit_tool.o main.o ../lib/libdia.la -lz -lfreetype -lz -lbz2 -pthread -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgio-2.0 -lpangocairo-1.0 -lcairo -lxml2 -lgdk_pixbuf-2.0 -lgthread-2.0 -lrt -lpangoft2-1.0 -lpango-1.0 -lfreetype -lfontconfig -lgobject-2.0 -lglib-2.0 -lart_lgpl_2 -lpng -lz -lm -lxml2 -lz -lpthread -lm -lart_lgpl_2 -lpng -lz -lm -lz libtool: link: clang -I/usr/include/libxml2 -I/usr/include/freetype2 -march=athlon64-sse3 -O2 -Wall --std=c89 -Wdeclaration-after-statement -Wmissing-prototypes -Wmissing-declarations -finline-functions -fstrict-aliasing -Wpointer-arith -Winit-self -Wformat-nonliteral -Wl,-O1 -Wl,--as-needed -o .libs/dia confirm.o exit_dialog.o diagram.o preferences.o load_save.o properties-dialog.o defaults.o undo.o object_ops.o layer_dialog.o commands.o app_procs.o connectionpoint_ops.o disp_callbacks.o display.o select.o color_area.o linewidth_area.o grid.o handle_ops.o interface.o modify_tool.o scroll_tool.o create_object.o magnify.o menus.o cut_n_paste.o render_gdk.o tool.o diapagelayout.o pagesetup.o filedlg.o find-and-replace.o plugin-manager.o dia-props.o gtkwrapbox.o gtkhwrapbox.o gtkvwrapbox.o cursor.o splash.o recent_files.o diagram_tree.o diagram_tree_window.o diagram_tree_menu.o diagram_tree_menu_callbacks.o sheets.o sheets_dialog.o sheets_dialog_callbacks.o autosave.o dynamic_refresh.o navigation.o diacanvas.o highlight.o textedit.o textedit_tool.o main.o -pthread -Wl,--export-dynamic ../lib/.libs/libdia.so -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgio-2.0 -lpangocairo-1.0 -lcairo -lgdk_pixbuf-2.0 -lgthread-2.0 -lrt -lpangoft2-1.0 -lpango-1.0 /usr/lib64/libfreetype.so -lbz2 -lfontconfig -lgobject-2.0 -lglib-2.0 -lxml2 -lpthread /usr/lib64/libart_lgpl_2.so -lpng -lm -lz -pthread -Wl,-rpath -Wl,/usr/lib64/dia ../lib/.libs/libdia.so: error: undefined reference to 'g_module_close' ../lib/.libs/libdia.so: error: undefined reference to 'g_module_error' ../lib/.libs/libdia.so: error: undefined reference to 'g_module_open' ../lib/.libs/libdia.so: error: undefined reference to 'g_module_symbol' clang: error: linker command failed with exit code 1 (use -v to see invocation) Reproducible: Always I additionally set CC="clang" CXX="clang++" which is clang 3.1.
