I was going through the config.log after installing R successfully on a Linux ppc64 machine. However, I could not install the MCMCpack and looked at the config.log file for gcc and g++ errors.I found some of them and have pasted them below. Please let me know if they can affect the installation of other packages on R. ------------------ configure:7479: checking whether we are using the GNU Objective C compiler configure:7508: gcc -c -I/usr/local/include conftest.m >&5 gcc: error trying to exec 'cc1obj': execvp: No such file or directory configure:7514: $? = 1 configure: failed program was: | /* confdefs.h. */ | #define PACKAGE_NAME "R" | #define PACKAGE_TARNAME "R" | #define PACKAGE_VERSION "2.5.0" | #define PACKAGE_STRING "R 2.5.0" | #define PACKAGE_BUGREPORT "r-bugs@R-project.org" | #define PACKAGE "R" | #define VERSION "2.5.0" | #define R_PLATFORM "powerpc64-unknown-linux-gnu" | #define R_CPU "powerpc64" | #define R_VENDOR "unknown" | #define R_OS "linux-gnu" | #define Unix 1 | #define R_ARCH "" | #define HAVE_VISIBILITY_ATTRIBUTE 1 | /* end confdefs.h. */ | | int | int | main () | { | #ifndef __GNUC__ | choke me | #endif | | ; | return 0; | } configure:7548: result: no configure:7553: checking whether gcc accepts -g configure:7583: gcc -c -g -I/usr/local/include conftest.m >&5 gcc: error trying to exec 'cc1obj': execvp: No such file or directory configure:7589: $? = 1 configure: failed program was: | /* confdefs.h. */ ......................... configure:7638: gcc -c -I/usr/local/include conftest.m >&5 gcc: error trying to exec 'cc1obj': execvp: No such file or directory configure:7644: $? = 1 configure: failed program was: | /* confdefs.h. */ ....................... configure:7694: gcc -c -g -I/usr/local/include conftest.m >&5 gcc: error trying to exec 'cc1obj': execvp: No such file or directory configure:7700: $? = 1 configure: failed program was: | /* confdefs.h. */ ....................... configure:7739: result: no configure:7792: gcc -c -I/usr/local/include conftest.m >&5 gcc: error trying to exec 'cc1obj': execvp: No such file or directory configure:7798: $? = 1 configure: failed program was: | /* confdefs.h. */ ...................... configure:41100: gcc -m64 -std=gnu99 -o conftest -mminimal-toc -fno-optimize-sibling-calls -g -O2 -I/usr/local/include -L/usr/local/lib conftest.c -framework vecLib -ldl -lm >&5 gcc: vecLib: No such file or directory cc1: error: unrecognized command line option "-framework" configure:41106: $? = 1 configure: failed program was: | /* confdefs.h. */ ........................ configure:46650: gcc -m64 -std=gnu99 -o conftest -mminimal-toc -fno-optimize-sibling-calls -g -O2 -I/usr/local/include -L/usr/local/lib conftest.c -framework CoreFoundation -ldl -lm >&5 gcc: CoreFoundation: No such file or directory cc1: error: unrecognized command line option "-framework" configure:46656: $? = 1 configure: failed program was: | /* confdefs.h. */ ........................ configure:56212: gcc -m64 -std=gnu99 -o conftest -mminimal-toc -fno-optimize-sibling-calls -g -O2 -I/usr/local/include -I/System/Library/Frameworks/CoreFoundation.framework/Headers -L/usr/local/lib conftest.c -ldl -lm -framework CoreFoundation >&5 gcc: CoreFoundation: No such file or directory cc1: error: unrecognized command line option "-framework" configure:56218: $? = 1 configure: failed program was: | /* confdefs.h. */ ....................... configure:56300: gcc -m64 -std=gnu99 -o conftest -mminimal-toc -fno-optimize-sibling-calls -g -O2 -I/usr/local/include -I/System/Library/Frameworks/CoreFoundation.framework/Headers -L/usr/local/lib conftest.c -ldl -lm -framework CoreFoundation >&5 gcc: CoreFoundation: No such file or directory cc1: error: unrecognized command line option "-framework" configure:56306: $? = 1 configure: failed program was: | /* confdefs.h. */ ......................

Should anything be done with respect to the other gcc errors?? Thanks, Vivek [[alternative HTML version deleted]]
