This must be a very common problem, but I have not yet been able to Google up a solution. Many Open Source programs come with a "configure" script that creates all the Makefiles and possibly a config.h header file. My problem is how to use configure when I want to cross-compile. In my particular case the host is Ubuntu 8.10 i386 and the target is Google Android ARM. Presently I'm trying to build glib, but I have lots of other sources that I'll need to cross-compile the same way. The glib documentation says that when cross-compiling, one needs to set up a cache file that is used by the configure script. My android.cache has: glib_cv_long_long_format=ll glib_cv_stack_grows=no These indicate that Android's printf format for 64-bit integers is %ll, and that the runtime stack grows downward. The first item in my $PATH is the bin directory that contains Android's arm-eabi-4.4.0 build of the GNU toolchain. The LDFLAGS parameter given to configure supplies the directory where my Android system build places all the shared libraries: $ ./configure --cache-file=android.cache --host=arm-linux LDFLAGS=-L/path/to/android/out/target/product/foofone/system/lib ... configure: error: C compiler cannot create executables See `config.log' for more details. Unfortunately, config.log doesn't give me a clue as to what actually failed. I thought at first that the problem was that the built executable, being an ARM binary, wouldn't run on i386. But now I think the problem is actually that the executable that configure was trying to build could not be built at all. Have you a clue for me? Thanks!
