Compiling libcurl for mingw32 (Windows) on mac os x 10.6

Question

I'm compiling libcurl for mingw32 as follows:

./configure --prefix=/Users/daniel/mingw32 "CFLAGS= -ABI=32"
make
make install

But when compiling a program using mingw32-gcc:

i386-mingw32-gcc -lcurl -o bin/remote-win.exe remote.c

i get:

In file included from /Users/daniel/mingw32/usr/local/include/curl/curl.h:34,
                 from remote.c:6:

/Users/daniel/mingw32/usr/local/include/curl/curlrules.h:153: error: size of array `__curl_rule_02__' is negative

I'm pretty sure the error is because curl_socklen_t does not exist on windows. I've tried --target=--mingw32 but still no success.

Please help

What is your configure output? Only at the end, from the line "configure: Configured to build curl/libcurl: " — osgx
@osgx i also get checking for sys/socket.h... (cached) yes the end line is above — Daniel
@Daniel, your configure done for MacOS, not for mingw. "--prefix" sets only install directory, but configure knows nothing about your mingw compiler and environment. Updated the answer. — osgx
@osgx Ok thanks for the answer. i'll try it and tell you if it worked or not — Daniel
Daniel, try a ' i386-pc-mingw32 ' for target and specify a CC parameter. Compiler line from configure output must begin with "Compiler: i386-mingw32-gcc " — osgx

Seems like mingw have no sys/socket.h. Just checked on my fresh mingw native install.

So, your application is not portable to mingw (or configure run was wrong). May be you should search or ask in Mailing List at http://curl.haxx.se

Thanks for your configure output. You did configed the curl for MacOSX itself, not for a cross-build for mingw. Your should force configure to use mingw's gcc, also you should to add cross-compilation options (at least '--target' option).
