Hello, I am trying to install the spice client on LFS-based machine. I resolved all the dependencies as stated by the "spice_user_manual.pdf" file. But while doing make in spice/client directory, an error is occuring as: /mnt/hdb1/SPICE/spice-0.5.2/client/x11/./atomic_count.h:32: undefined reference to `__sync_sub_and_fetch_4' /mnt/hdb1/SPICE/spice-0.5.2/client/x11/./atomic_count.h:32: undefined reference to `__sync_sub_and_fetch_4' /mnt/hdb1/SPICE/spice-0.5.2/client/x11/./atomic_count.h:32: undefined reference to `__sync_sub_and_fetch_4' /mnt/hdb1/SPICE/spice-0.5.2/client/x11/./atomic_count.h:32: undefined reference to `__sync_sub_and_fetch_4' application.o: In function `AtomicCount::operator--()': /mnt/hdb1/SPICE/spice-0.5.2/client/x11/./atomic_count.h:32: undefined reference to `__sync_sub_and_fetch_4' application.o:/mnt/hdb1/SPICE/spice-0.5.2/client/x11/./atomic_count.h:32: more undefined references to `__sync_sub_and_fetch_4' follow collect2: ld returned 1 exit status make[5]: *** [spicec] Error 1 make[5]: Leaving directory `/mnt/hdb1/SPICE/spice-0.5.2/client/x11' make[4]: *** [all-recursive] Error 1 make[4]: Leaving directory `/mnt/hdb1/SPICE/spice-0.5.2/client/x11' make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory `/mnt/hdb1/SPICE/spice-0.5.2/client' make[2]: *** [all] Error 2 I do not find any reference to the "__sync_sub_and_fetch_4". I installed the Spice server on Fedora-12, and The installation was fine as per the expectation. I tried the version 0.4.0 and 0.5.2, for both I stuck at the same place. Please guide me for further installation process. Thanks and Regards, Satish
