Problem when compiling gcc 4.6.2: checking for avr-gcc... /data/data6/soft/src_build/gcc-4.6.2/host-x86_64-unknown-linux-gnu/gcc/xgcc -B/data/data6/soft/src_build/gcc-4.6.2/host-x86_64-unknown-linux-gnu/gcc/ -B/data/data6/soft/programming/gcc-avr/avr/bin/ -B/data/data6/soft/programming/gcc-avr/avr/lib/ -isystem /data/data6/soft/programming/gcc-avr/avr/include -isystem /data/data6/soft/programming/gcc-avr/avr/sys-include checking for suffix of object files... configure: error: in `/data/data6/soft/src_build/gcc-4.6.2/avr/libgcc': configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. In my gcc-4.6.2/avr/libgcc/config.log I found: configure:3268: /data/data6/soft/src_build/gcc-4.6.2/host-x86_64-unknown-linux-gnu/gcc/xgcc -B/data/data6/soft/src_build/gcc-4.6.2/host-x86_64-unknown-linux-gnu/gcc/ -B/data/data6/soft/programming/gcc-avr/avr/bin/ -B/data/data6/soft/programming/gcc-avr/avr/lib/ -isystem /data/data6/soft/programming/gcc-avr/avr/include -isystem /data/data6/soft/programming/gcc-avr/avr/sys-include -c -g -O2 conftest.c >&5 exec: 89: -o: not found configure:3272: $? = 1 configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "GNU C Runtime Library" | #define PACKAGE_TARNAME "libgcc" | #define PACKAGE_VERSION "1.0" | #define PACKAGE_STRING "GNU C Runtime Library 1.0" | #define PACKAGE_BUGREPORT "" | /* end confdefs.h. */ | | int | main () | { | | ; | return 0; | } configure:3286: error: in `/data/data6/soft/src_build/gcc-4.6.2/avr/libgcc': configure:3289: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. If this command run directly (after creating conftest.c) output will be same. What is exec: 89: -o: not found? Which program write it? Where is 89 line? Solutions like exporting LD_CONFIG_PATH or adding lines in /etc/ld.so.conf with path to GMP, MPFR, MPC
