Hello,

        I'm trying to cross-compile an application for uClinux that relies
on Libcurl, but it fails compiling.

First, I add the right toolchain in the PATH, and ran the following:
================
./configure --disable-gpg ac_cv_func_malloc_0_nonnull=yes
--build=i686-pc-linux --host=bfin-linux-uclibc
target=bfin-linux-uclibc CC=bfin-linux-uclibc-gcc
AR=bfin-linux-uclibc-ar RANLIB=bfin-linux-uclibc-ranlib CFLAGS="-O2
-Wall -I/usr/src/uClinux-dist-2010R1-RC5/linux-2.6.x/include
-I/usr/src/uClinux-dist-2010R1-RC5/lib/libcurl/curl-7.19.6/include"
LDFLAGS="-static
-L/usr/src/uClinux-dist-2010R1-RC5/lib/libcurl/build-curl-7.19.6/lib/.libs"
================

Next, I ran "make", which fails thusly:
================
  CC opkg_download.o

Does someone know what to do?

Thank you.
