Hi, I'm also getting exactly the same error in Ubuntu 8.10 after upgrading to kernel 2.6.27-9.
Steps to reproduce: sudo apt-get install exmap exmap-modules-source cd /usr/src sudo tar xvzf exmap.tar.gz cd modules/exmap sudo make make -C /lib/modules/2.6.27-9-generic/build M=/usr/src/modules/exmap modules make[1]: Entering directory `/usr/src/linux-headers-2.6.27-9-generic' CC [M] /usr/src/modules/exmap/exmap.o /usr/src/modules/exmap/exmap.c: In function ‘setup_from_pid’: /usr/src/modules/exmap/exmap.c:395: error: implicit declaration of function ‘find_task_by_pid’ /usr/src/modules/exmap/exmap.c:395: warning: assignment makes pointer from integer without a cast /usr/src/modules/exmap/exmap.c: In function ‘init_module’: /usr/src/modules/exmap/exmap.c:510: error: ‘proc_root’ undeclared (first use in this function) /usr/src/modules/exmap/exmap.c:510: error: (Each undeclared identifier is reported only once /usr/src/modules/exmap/exmap.c:510: error: for each function it appears in.) /usr/src/modules/exmap/exmap.c: In function ‘cleanup_module’: /usr/src/modules/exmap/exmap.c:535: error: ‘proc_root’ undeclared (first use in this function) make[2]: *** [/usr/src/modules/exmap/exmap.o] Error 1 make[1]: *** [_module_/usr/src/modules/exmap] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-2.6.27-9-generic' make: *** [kernel_modules] Error 2 -- cannot build exmap module in intrepid ibex https://bugs.launchpad.net/bugs/284863 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
