Building libcurl static library for DMD32 Windows

Please note that these instructions will compile libcurl static library without SSL support.

Required tools

• MinGW-make (http://www.mingw.org)
• Digital Mars Compiler (http://ftp.digitalmars.com/Digital_Mars_C++/Patch/dm857c.zip)

Building curl_static_dmc.lib

1. Create directory C:\BUILD
2. Download http://curl.haxx.se/download/curl-7.37.0.zip and extract it into C:\BUILD
3. cd C:\BUILD\curl-7.37.0

Open include\curl\curlbuild.h in your favorite editor and add the following to line 188:

#elif defined(__DMC__)
#  define CURL_SIZEOF_LONG           4
#  define CURL_TYPEOF_CURL_OFF_T     long long
#  define CURL_FORMAT_CURL_OFF_T     "lld"
#  define CURL_FORMAT_CURL_OFF_TU    "llu"
#  define CURL_FORMAT_OFF_T          "%lld"
#  define CURL_SIZEOF_CURL_OFF_T     8
#  define CURL_SUFFIX_CURL_OFF_T     LL
#  define CURL_SUFFIX_CURL_OFF_TU    ULL
#  define CURL_TYPEOF_CURL_SOCKLEN_T int
#  define CURL_SIZEOF_CURL_SOCKLEN_T 4

Open include\curl\curlrules.h and add || defined(__DMC__) to line 207:

#if defined(__STDC__) || defined(_MSC_VER) || defined(__cplusplus) || \
  defined(__HP_aCC) || defined(__BORLANDC__) || defined(__LCC__) || \
  defined(__POCC__) || defined(__SALFORDC__) || defined(__HIGHC__) || \
  defined(__ILEC400__) || defined(__DMC__)

Open lib\config-win32.h and add && !defined(__DMC__) to line 566

#if !defined(__SALFORDC__) && !defined(__BORLANDC__) && !defined(__DMC__)
#define HAVE_STRUCT_SOCKADDR_STORAGE 1
#endif

Open lib\curl_setup.h and add the following to line 504

#if defined(__DMC__)
#  undef USE_THREADS_POSIX
#  undef USE_THREADS_WIN32
#endif

Save the following as C:\BUILD\curl-7.37.0\lib\Makefile.dmc
