Hi guys I got the errors like this while compiling cluster glue: ./.libs/libplumb.so: undefined reference to `uuid_parse' ./.libs/libplumb.so: undefined reference to `uuid_generate' ./.libs/libplumb.so: undefined reference to `uuid_copy' ./.libs/libplumb.so: undefined reference to `uuid_is_null' ./.libs/libplumb.so: undefined reference to `uuid_unparse' ./.libs/libplumb.so: undefined reference to `uuid_clear' ./.libs/libplumb.so: undefined reference to `uuid_compare' collect2: ld returned 1 exit status gmake[2]: *** [ipctest] Error 1 gmake[2]: Leaving directory `/root/Reusable-Cluster-Components-glue-1.0.5/lib/clplumbing' gmake[1]: *** [all-recursive] Error 1 gmake[1]: Leaving directory `/root/Reusable-Cluster-Components-glue-1.0.5/lib' make: *** [all-recursive] Error 1 and here is the output when I run ./configure: configure: creating ./config.status config.status: creating Makefile config.status: creating config.h config.status: config.h is unchanged config.status: executing depfiles commands cluster-glue configuration: Version = 1.0.6 (Build: 1c87a0c58c59fc384b93ec11476cefdbb6ddc1e1) Features = Prefix = /usr Executables = /usr/sbin Man pages = /usr/man Libraries = /usr/lib Header files = /usr/include Arch-independent files = /usr/share Documentation = /usr/share/doc State information = /usr/var System configuration = /usr/etc Use system LTDL = no HA group name = haclient HA user name = hacluster CFLAGS = -g -O2 -ggdb3 -O0 -fgnu89-inline -fstack-protector-all -Wall -Waggregate-return -Wbad-function-cast -Wcast-qual -Wcast-align -Wdeclaration-after-statement -Wendif-labels -Wfloat-equal -Wformat=2 -Wformat-security -Wformat-nonliteral -Winline -Wmissing-prototypes -Wmissing-declarations -Wmissing-format-attribute -Wnested-externs -Wno-long-long -Wno-strict-aliasing -Wpointer-arith -Wstrict-prototypes -Wwrite-strings -ansi -D_GNU_SOURCE -DANSI_ONLY -Werror Libraries = -lbz2 -lxml2 -lc -lrt -ldl -L/lib -lglib-2.0 Stack Libraries = I found that some one said that maybe I need libuuid-devel. but when I tried to install libuuid-2.17.2-4.el6.i686.rpm and libuuid-devel-2.17.2-4.el6.i686.rpm I still got this: # rpm -ihv libuuid-2.17.2-4.el6.i686.rpm libuuid-devel-2.17.2-4.el6.i686.rpm warning: libuuid-2.17.2-4.el6.i686.rpm: Header V3 RSA/SHA256 signature: NOKEY, key ID f21541eb error: Failed dependencies: rpmlib(FileDigests) <= 4.6.0-1 is needed by libuuid-2.17.2-4.el6.i686 rpmlib(PayloadIsXz) <= 5.2-1 is needed by libuuid-2.17.2-4.el6.i686 rpmlib(FileDigests) <= 4.6.0-1 is needed by libuuid-devel-2.17.2-4.el6.i686 rpmlib(PayloadIsXz) <= 5.2-1 is needed by libuuid-devel-2.17.2-4.el6.i686 what should I do to fix those problems? you will be very appreciated for any suggestion. thank you -- Tang Jianwei
