Summary:                    curl does not seem to work when cross-compiling
Description: 
I am trying to get curl available under astlinux - but there seems to be a
problem when cross-compiling curl_lib. 

the error is :

[LD] func_curl.o -> func_curl.so
/usr/src/astlinux/build_i586/staging_dir/bin-ccache/../lib/gcc/i586-linux-uclibc/4.1.2/../../../../i586-linux-uclibc/bin/ld:
cannot find -lcurl
collect2: ld returned 1 exit status
make[2]: *** [func_curl.so] Error 1

I would be that unnamed developer above.

The issue is the following.  When you're cross-compiling, the whole notion
of something like "curl-config" is just plain wrong.

The host system's curl-config can give correct results when *not*
cross-compiling (i.e. for a local build).

The target system's curl-config will give correct results *when run on the
target system*, and they will be correct relative to the target system's
root filesystem.

However, you simply can't run "curl-config" (host or target) because
neither versus is appropriate in a cross-compilation setting.

So, the only way about this is to allow passing in explicit paths via
ac_cv_* variables, or else add a few more --with-curl-* arguments
(--with-curl-include, --with-curl-libs, --with-curl-libdir, etc).

These options should work both in native compilation and cross-compilation
modes.

But under no circumstances should curl-config ever be used in
cross-compilation.

Period.
