i think i'm confused about the support for device mapper in the 2.6 kernel. i'm aware that i need to install device-mapper for LVM2, and i know where to get the device-mapper tarball. but, in the configuration process for the 2.6 kernel, you can select device mapper support, so i did and built it into the kernel. i assumed (perhaps unwisely) that device mapper was now part of the 2.6 kernel source tree, and i now had it since i'd selected it as part of the configuration in the kernel build for my 2.6.0-test11 kernel. therefore, i didn't need to explicitly install device-mapper anymore. however, when i went to configure/make LVM2 on my FC1 system, the configure worked fine, but the make gave me: ... gcc -c -I. -I../include -DLVM1_INTERNAL -DDEVMAPPER_SUPPORT -DO_DIRECT_SUPPORT -DHAVE_LIBDL -DHAVE_GETOPTLONG -fPIC -Wall -Wundef -Wshadow -Wcast-align -Wwrite-strings -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline -O2 cache/lvmcache.c -o cache/lvmcache.o In file included from activate/activate.c:9: activate/activate.h:13:28: libdevmapper.h: No such file or directory activate/activate.c: In function `library_version': activate/activate.c:119: warning: implicit declaration of function `dm_get_library_version' activate/activate.c: In function `driver_version': activate/activate.c:133: warning: implicit declaration of function `dm_task_create' activate/activate.c:133: error: `DM_DEVICE_VERSION' undeclared (first use in this function) activate/activate.c:133: error: (Each undeclared identifier is reported only once activate/activate.c:133: error: for each function it appears in.) activate/activate.c:133: warning: assignment makes pointer from integer without a cast activate/activate.c:138: warning: implicit declaration of function `dm_task_run' activate/activate.c:141: warning: implicit declaration of function `dm_task_get_driver_version' activate/activate.c:147: warning: implicit declaration of function `dm_task_destroy' activate/activate.c: In function `_lv_info': activate/activate.c:160: error: storage size of `dminfo' isn't known activate/activate.c:160: warning: unused variable `dminfo' make[1]: *** [activate/activate.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make[1]: Leaving directory `/home/rpjday/SW/lvm/LVM2.2.00.08/lib' make: *** [lib] Error 2 note the reference to no libdevmapper.h file. so what's the proper recipe? what exactly was the effect of adding device-mapper support to my kernel? do i still have to explicitly configure/make and install device-mapper myself? am i just confused? rday _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
