how I "set the BUILD_CC environment variable "?

hi hippo:

Thanks for you reply.

Frist I have successed make ncurese by you guide.

Then I must cross compile cdk(curses d k).It is a devlope tool for ncurses.

I still edit configure.sub and use configure option as your post.

but not select crosscompile option in configure process.

[alex@localhost cdk-5.0-20060220]$ ./configure --host=nios2-linux-uclibc --with-build-cc=gcc --disable-shared

loading cache ./config.cache

checking for X... (cached) libraries /usr/X11R6/lib, headers /usr/X11R6/include

checking host system type... nios2-altera-linux-gnu

(cached) Configuring for linux-gnu

checking for package version... 5.0

checking for package patch date... 20060220

checking for gcc... (cached) gcc

checking whether the C compiler (gcc ) works... yes

checking whether the C compiler (gcc ) is a cross-compiler... no

checking whether we are using GNU C... (cached) yes

I try another ./configure option, for example:

[alex@localhost cdk-5.0-20060220]$ ./configure --build=nios2 --host--nios2-linux-uclibc --with-build-cc=gcc --disable-shared

[alex@localhost cdk-5.0-20060220]$ ./configure --host--nios2-linux-uclibc --with-build-cc=nios2-linux-uclibc-gcc --disable-shared

etc....

but I still fail.

Please help me.

If I make success, I will test the ncurses in my dvb. Then post porting method

to forum.The ncurses is a very helpful terminal tool for us.It can make tab,menu,

....in a terminal like a Kernel make menuconfig windows.
