Hi All, I want to build a cross gcc toolchain without hardware float point unit. My configuration for building gcc is: ================================================================ Using built-in specs. Target: arm-elf Configured with: ../gcc-4.4.3/configure --prefix=/home/panruochen/gcc-4.4.3 --program-prefix=arm-elf- --target=arm-elf --with-gmp=/home/panruochen/gmp-5.0.2 --with-mpfr=/home/panruochen/mpfr-3.0.1 --with-gnu-as --with-gnu-ld --enable-languages=c --with-cache=config.cache --disable-libada --disable-libssp --with-float=soft --disable-fpu Thread model: single gcc version 4.4.3 (GCC) ================================================================ When I compile and link against the toolchain, I get the following errors: ================================================================ arm-elf-ld: error: /cygdrive/c/gcc-4.4.3/bin/../lib/gcc/arm-elf/4.4.3/libgcc.a(_udivsi3.o) uses FPA instructions, whereas a.elf does not arm-elf-ld: failed to merge target specific data of file /cygdrive/c/gcc-4.4.3/bin/../lib/gcc/arm-elf/4.4.3/libgcc.a(_udivsi3.o) arm-elf-ld: error: /cygdrive/c/gcc-4.4.3/bin/../lib/gcc/arm-elf/4.4.3/libgcc.a(_divsi3.o) uses FPA instructions, whereas a.elf does not arm-elf-ld: failed to merge target specific data of file /cygdrive/c/gcc-4.4.3/bin/../lib/gcc/arm-elf/4.4.3/libgcc.a(_divsi3.o) arm-elf-ld: error: /cygdrive/c/gcc-4.4.3/bin/../lib/gcc/arm-elf/4.4.3/libgcc.a(_umodsi3.o) uses FPA instructions, whereas a.elf does not arm-elf-ld: failed to merge target specific data of file /cygdrive/c/gcc-4.4.3/bin/../lib/gcc/arm-elf/4.4.3/libgcc.a(_umodsi3.o) arm-elf-ld: error: /cygdrive/c/gcc-4.4.3/bin/../lib/gcc/arm-elf/4.4.3/libgcc.a(_dvmd_tls.o) uses FPA instructions, whereas a.elf does not arm-elf-ld: failed to merge target specific data of file /cygdrive/c/gcc-4.4.3/bin/../lib/gcc/arm-elf/4.4.3/libgcc.a(_dvmd_tls.o) arm-elf-ld: error: /cygdrive/c/gcc-4.4.3/bin/../lib/gcc/arm-elf/4.4.3/libgcc.a(_lshrdi3.o) uses FPA instructions, whereas a.elf does not arm-elf-ld: failed to merge target specific data of file /cygdrive/c/gcc-4.4.3/bin/../lib/gcc/arm-elf/4.4.3/libgcc.a(_lshrdi3.o) ================================================================ These messages shall mean libgcc is compiled with hardware float supported. The configuration options `--with-float=soft --disable-fpu' donot work. So, what is the appropriate configuration option? -- Best Regards, Pan Ruochen
