Problema com / usr / bin / ld: main.o: referência indefinida ao símbolo 'exp @@ GLIBC_2.2.5'

Question

Durante a instalação do Emerald no ubuntu 13.04 quando eu escrevo "sudo make" eu tenho problema:

libtool: link: gcc -g -O2 -pthread -I/usr/include/libwnck-1.0 -I/usr/include/compiz -I/usr/include/gtk-2.0 -I/usr/lib/x86_64-linux-gnu/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/pango-1.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng12 -I/usr/include/harfbuzz -I/usr/include/startup-notification-1.0 -o .libs/emerald main.o engine_loader.o  ../libengine/.libs/libemeraldengine.so -lwnck-1 -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgio-2.0 -lpangoft2-1.0 -lgdk_pixbuf-2.0 /usr/lib/x86_64-linux-gnu/libfreetype.so -lfontconfig -ldecoration -lXrender -lX11 -lpangocairo-1.0 -lpango-1.0 /usr/lib/x86_64-linux-gnu/libcairo.so -lgobject-2.0 -lglib-2.0 -pthread

Answer 1

Isso é um pouco complicado, mas funciona:

Edite o arquivo configure.ac encontrado na pasta de origem da esmeralda. Lá, de forma aproximada na linha 55, você encontrará a seguinte linha:

LIBS="$LIBS $EMERALD_LIBS"

Altere para

LIBS="$LIBS $EMERALD_LIBS -lm -ldl"

e refaça as etapas. Vai funcionar.
