cross compile with ./configure

did you try ./configure --help ?

f there was a CROSS_COMPILE option, it would be preceded with --, for example: --host=HOST cross-compile to build programs to run on HOST [BUILD]

Typically you can use the following environmental variables CC C compiler command CFLAGS C compiler flags LDFLAGS linker flags, e.g. -L if you have libraries in a nonstandard directory LIBS libraries to pass to the linker, e.g. -l CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I if you have headers in a nonstandard directory CPP C preprocessor CXX C++ compiler command CXXFLAGS C++ compiler flags CXXCPP C++ preprocessor

--host=HOST cross-compile to build programs to run on HOST [BUILD]

did you install a toolchain for cross compiling (the appropriate gcc etc) ?

$./configure CC=arm-unknown-linux-gnu-gcc configure: warning: CC=arm-unknown-linux-gnu-gcc: invalid host type

$ CROSS_COMPILE=arm-unknown-linux-gnu- $ ./configure --host=i686-linux --target=arm-linux (script runs but make terminates with error)

$ CC=arm-unknown-linux-gnu- $ ./configure

... checking for gcc... (cached) gcc checking whether the C compiler (gcc ) works... yes checking whether the C compiler (gcc ) is a cross-compiler... no ...

So, each of these tries resulted in non working settings. My cross toolchain is installed and in my PATH.

You ought to post the error

It doesn't seem to work.

Configure is trying to tell you that your c compiler isn't capable of cross compilation.

Look into the configure script to see how it is performing it's test.

OK, I got it working. Instead of "apt-get source", I downloaded the original source from freshmeat. Then issued:

$ CC=arm-unknown-linux-gnu-gcc ./configure --host=arm-unknown-linux-gnu

It configured and cross-compiled successfully.

Try $ CC=arm-unknown-linux-gnu-gcc ./configure --host=arm-unknown-linux-gnu

That setting of a variable won't be seen by teh configure script. Either export it as an environmental variable to be exported to spawned processes, or include it in the ./configure line thus:

$ CROSS_COMPILE=arm-unknown-linux-gnu- ./configure --host=i686-linux

--target=arm-linux

Ditto. Look up 'export' in your bash manpage.
