I'm having problems putting together a gcc toolchain for an xscale processor that doesn't have floating-point support. I used crosstool-0.29, setting the 'eval' line of demo-arm-xscale.sh to be: eval `cat arm-xscale.dat gcc-3.3.2-glibc-2.3.2.dat` sh all.sh --notest I changed arm-xscale.dat to read: KERNELCONFIG=`pwd`/arm.config TARGET=arm-linux TARGET_CFLAGS="-O" GCC_EXTRA_CONFIG="--with-float=soft --with-cpu=xscale --enable-cxx-flags=-mcpu=xscale" GLIBC_EXTRA_CONFIG="--without-fp" When it's all done typing 'arm-linux-gcc --verb' gives: Reading specs from /usr/local/arm-linux/bin/../lib/gcc-lib/arm-linux/3.3.2/specsConfigured with: /home/ali/olo/crosstool-0.29/build/arm-linux/gcc-3.3.2-glibc-2.3.2/gcc-3.3.2/configure --target=arm-linux --host=i686-host_pc-linux-gnu --prefix=/usr/local/crosstool/arm-linux/gcc-3.3.2-glibc-2.3.2 --with-float=soft --with-cpu=xscale --enable-cxx-flags=-mcpu=xscale --with-headers=/usr/local/crosstool/arm-linux/gcc-3.3.2-glibc-2.3.2/arm-linux/include --with-local-prefix=/usr/local/crosstool/arm-linux/gcc-3.3.2-glibc-2.3.2/arm-linux --disable-nls --enable-threads=posix --enable-symvers=gnu --enable-__cxa_atexit --enable-languages=c,c++ --enable-shared --enable-c99 --enable-long-long But when I try to compile and link my software, I get a bunch of errors of the form: /usr/local/arm-linux/bin/../lib/gcc-lib/arm-linux/3.3.2/../../../../arm-linux/bin/ld: ERROR: /usr/local/arm-linux/bin/../lib/gcc-lib/arm-linux/3.3.2/../../../../arm-linux/lib/libc_nonshared.a(elf-init.oST) uses hardware FP, whereas arm-linux-elf/vdc_basic_test.full uses software FP File format not recognized: failed to merge target specific data of file /usr/local/arm-linux/bin/../lib/gcc-lib/arm-linux/3.3.2/../../../../arm-linux/lib/libc_nonshared.a(elf-init.oST) / When I run 'arm-linux-objdump -p` on that .a file, I get: elf-init.oST: file format elf32-littlearm private flags = 0: [APCS-32] [FPA float format] Does that mean that it _didn't_ get built with software fp support? Can anyone see what I'm doing wrong? Ali ------ Want more information? See the CrossGCC FAQ, http://www.objsw.com/CrossGCC/ Want to unsubscribe? Send a note to crossgcc-unsubscribe@sources.redhat.com
