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

Using the static lib

Since dmd 2.069.0 all the curl symbols need to be exported so that std.net.curl can load them from the executable. This can be achieved by additionally linking with export_curl.def.

EXETYPE NT
EXPORTS
curl_global_init
curl_global_cleanup
curl_version_info
curl_easy_init
curl_easy_setopt
curl_easy_perform
curl_easy_duphandle
curl_easy_strerror
curl_easy_pause
curl_easy_cleanup
curl_slist_append
curl_slist_free_all
