Hello, Rob.

Thank you for your kind explanation. I tried as you suggested, but the result was disappointing. Please, refer to the following console message and give me direction.

./configure --enable-speed --disable-debugging --enable-fpm=arm --enable-aso --host=arm CC=/opt/uClinux/bin/arm-elf-gcc RANLIB=/opt/uClinux/bin/arm-elf-ranlib LD=/opt/uClinux/bin/arm-elf-ld configure: warning: CC=/opt/uClinux/bin/arm-elf-gcc: invalid host type configure: warning: RANLIB=/opt/uClinux/bin/arm-elf-ranlib: invalid host type configure: error: can only configure for one host and one target at a time

I am trying to run MAD on ARM7TDMI based machine. I use uClinux.

When I execute ./configure as recommended in this mailing list, I faced a followinf error message:

[yslee@romeo mad-old]$ rm config.cache [yslee@romeo mad-old]$ CC=/opt/uClinux/bin/arm-elf-gcc RANLIB=/opt/uClinux/bin/arm-elf-ranlib LD=/opt/uClinux/bin/arm-elf-ld ./configure --enable-speed --disable-debugging --enable-fpm=arm --enable-aso --target=arm [...] checking for gcc... /opt/uClinux/bin/arm-elf-gcc checking whether the C compiler (/opt/uClinux/bin/arm-elf-gcc ) works... no configure: error: installation or configuration problem: C compiler cannot create executables.

How can I solve this problem?

Try invoking 'configure' like this:

./configure --enable-speed --disable-debugging --enable-fpm=arm \ --enable-aso --host=arm \ CC=/opt/uClinux/bin/arm-elf-gcc \ RANLIB=/opt/uClinux/bin/arm-elf-ranlib \ LD=/opt/uClinux/bin/arm-elf-ld

The reason:

1. --target is for building cross-compilers only. Use --host to specify the system that will run the code you are compiling now.

2. The autoconf suite prefers that you pass environment variables on the command line rather than through the environment, to overcome certain problems propagating the values.
