gcc: symbol lookup error: ...libgendep.so: undefined symbol: dlsym
Hi, I saw someone ran into this same problem a couple of years ago but I didn't see a solution posted. I just updated my OS to Ubuntu 11 and all of a sudden I am hitting this error when I run make setup and target either x86 or ARM. gcc: symbol lookup error: ...libgendep.so: undefined symbol: dlsym I see -ldl on the gcc line when building libgendep.so, but when I ldd libgendep.so it only prints linux-gate.so.1, libc.so.6, and /lib/ld-linux.so.2. libdl.so.2 exists and is in my ld cache. I am using gcc (Ubuntu/Linaro) 4.6.1. Thanks, -- Wesley Miaw wesley@wesman.net

In 11.10 Ubuntu changed the default behaviour of ld. Add -Wl,--no-as-needed after -shared in l4/tool/gendep/Makefile. Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/
