Hi, When I build gcc first time this which the configure parameter is like this:
../rice-gcc-4.3.0/configure --target=$TARGET --prefix=$PREFIX --enable-languages=c --without-headers --with-newlib --with-gnu-as --with-gnu-ld --disable-multilib --disable-libssp Binutils is ok and install in the $PREFIX path. Error information is like this: checking for /home/daniel.tian/gcc_rice_dev/rice-binutils/build-gcc/./gcc/xgcc -B/home/daniel.tian/gcc_rice_dev/rice-binutils/build-gcc/./gcc/ -B/usr/local/cross/rice-elf/rice-elf/bin/ -B/usr/local/cross/rice-elf/rice-elf/lib/ -isystem /usr/local/cross/rice-elf/rice-elf/include -isystem /usr/local/cross/rice-elf/rice-elf/sys-include option to accept ANSI C... none needed checking how to run the C preprocessor... /home/daniel.tian/gcc_rice_dev/rice-binutils/build-gcc/./gcc/xgcc -B/home/daniel.tian/gcc_rice_dev/rice-binutils/build-gcc/./gcc/ -B/usr/local/cross/rice-elf/rice-elf/bin/ -B/usr/local/cross/rice-elf/rice-elf/lib/ -isystem /usr/local/cross/rice-elf/rice-elf/include -isystem /usr/local/cross/rice-elf/rice-elf/sys-include -E checking whether decimal floating point is supported... no checking whether fixed-point is supported... no *** Configuration rice-mavrix-elf not supported make[1]: *** [configure-target-libgcc] Error 1 make[1]: Leaving directory `/home/daniel.tian/gcc_rice_dev/rice-binutils/build-gcc' make: *** [all] Error 2 rice-mavrix-elf : rice is my target name. I search the configure in libgcc, there is no target information. And I check the CRX port, it also didn't add more information than I did. Can anybody give me some clue to debug it? Any suggestion is appreciated. Thank you very much. Daniel.Tian
