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<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  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]

$./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.

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