Hi everybody,

I'm on ubuntu 14.04 64 bits, and I'm trying to cross compile libcurl as a
static library with OpenSSL to windows 64bits using mingw32, but I get an
error.

First I cross compile statically OpenSSL 1.0.1j :

cd openssl-1.0.1j/
export CROSS_COMPILE="x86_64-w64-mingw32-"
./Configure mingw64 no-asm no-shared
make depend
make && sudo make install

Then I try to cross compile statically libcurl :

cd curl-7.39.0/
export LDFLAGS="-L/usr/local/ssl/lib"
export CPPFLAGS="-I/usr/local/ssl/include"
./configure --host=x86_64-w64-mingw32 --disable-shared --disable-ldap
--without-librtmp --with-ssl=/usr/local/ssl
make

And then I get the error. It looks related to openssl and indeed if I
disable openssl then libcurl compiles correctly. The error:

Can anyone shed some light into this subject?
