HI ALL,

I want to cross compile GDB to ARM platform , the configure run is fine , but it occurred error when make file,

Here is my make script,

Code:

export PATH=/tools/arm-none-linux-gnueabi/bin:$PATH
export CC=arm-none-linux-gnueabi-gcc
export CXX=arm-none-linux-gnueabi-g++
export CXX=CC

./configure \
 --prefix=/root/Download/Packages/gdb-6.5/arm \
 --verbose \
 --host=arm-none-linux-gnueabi \
 --build=i686-pc-linux-gnu \
 --target=arm-none-linux-gnueabi \

make

It always return following error message when make,

Quote:

[root@localhost gdb-6.5]# make
make[1]: Entering directory `/root/Download/Packages/gdb-6.5'
Configuring in ./libiberty
configure: loading cache ./config.cache
configure: error: `CC' has changed since the previous run:
configure: former value: gcc
configure: current value: arm-none-linux-gnueabi-gcc
configure: error: changes in the environment can compromise the build
configure: error: run `make distclean' and/or `rm ./config.cache' and start over
make[1]: *** [configure-libiberty] Error 1
make[1]: Leaving directory `/root/Download/Packages/gdb-6.5'
make: *** [all] Error 2

Best Regards,
Ke Tao

Run make -e instead of just make. The -e flag tells make to give environment variables precedence over variables defined in the makefile.
