      Stay away from Cygwin.

      If you cannot use MSVS.. at least use MingGW.

      Here's the link to download the source (which comes with precompiled binaries for curl.exe)
      http://curl.haxx.se/gknw.net/7.26.0/dist-w32/curl-7.26.0-devel-mingw32.zip

      OR.. if you just simply want the precompiled binaries (without source):
      http://curl.haxx.se/gknw.net/7.26.0/dist-w32/curl-7.26.0-rtmp-ssh2-ssl-sspi-zlib-idn-static-bin-w32.zip
      Has both pre-compiled curl.exe and libcurl.dll, as well as a few more dll files.


      And how to build on various platforms:

        I would assume this would mean the end user would need to install the gem for it to work?

              Well, no... gems do not work with Sketchup embedded Ruby.

              Actually want is probably needed is to look at the handfull of gems and write a Sketchup friendly "clone".

                My advice. (From what I have read.)

                If you want expert advice, ask Luis Lavena over at the Ruby Installer project forum.

                    Hey guys, so I finally got a Ruby C extension to compile on both os x and windows and link curllib. I got a lot of help from Luis at the RubyInstaller group and ended up using RubyInstaller and DevKit to link curl and build using the gcc compiler included with devkit.
                    Here is the extension. Its a modified version of Dana's sketchup downloader, but also included uploading, basic http authentication and ssl certificate checking(all through curl). I provided instructions on how to build on both os x and windows.

                    https://github.com/sunglass/SunglassPlugins/tree/master/SG-SketchupHook/src/Connection%20Manager

                    Thanks for all your help guys.

                    Dana - Lets get your Sketchup downloader plugin working.

                            I would think it would depend upon which MSVC runtime you use.

                            Which ever you use, the user(s) will need to have that version installed on their machine(s), regardless of whether they are running Win5.1 (XP,) Win6.0 (Vista) or Win6.1 (Win7.)

                            SketchUp itself lists MSVC ver 8.x (2005) as a dependent assembly in it's manifest.

                            There ARE some programmers that have compiled extensions and linked to ver 10 (2010), but they must give the Microsoft download link to install that runtime version, and list it as a dependancy.

                            Reference:
                            http://en.wikipedia.org/wiki/Visual_C++

                              Hmm, I have win7 and windowns XP mode virtual pc, on the same comp.

                              Under Win6.1(win7), I recompiled win32/api.so to my own namespace with a name changed to win32/msp_api.so. ( MSPhysics::Win32::API)
                              It worked pretty well, until I've desided test it on WinXP mode virtual pc. WinXPmode had ruby-186-27, SU8, and some more raw programs, though it did not have MSVC.
                              Then, I started SU 8 and got this error:
                              msp_api.so without msft visual c++

                              Before I installed msvc 2010, I desided to test the native win32/api.so and seeing it working wasn't expected; Apperently the native win32/api.so worked pretty well, without showing any errors, and without msvc.

                              Being a little confused I desided to download msvc 2010 Redistributable Package (x86), to test whether my win32/msp_api.so would actually work on XPmode. After downloading, it worked now, but there was one question left: How did native win32/api.somanaged to work without msvc? ❓

                                No - you don't have to link to the runtime.

                                After a simple change in a compiler flag I could use the .so without the runtime installed.

                                  Because the SketchUp Installer installs MSVC 8.x (2005) runtime if it is not installed. The MSVC runtime install, might seem transparent to the user installing SketchUp, if they do not pay close attention.

                                  Most XP machines will likely already have this older MSVC ".NET" runtime version installed if Automatic Windows Updates are turned ON.

                                  I'm not here much anymore.

                                      I am trying to build the Basic sample under Xcode 4.4, but I am probably doing something wrong, because the resulting bundle fails to load into SU. I get "#<LoadError: myplugin.bundle Failed to load myplugin.bundle". I do not even get the "Failed to find init.. " error.

                                      When compiling with extconf.rb and make the plugin loads just fine.

                                      What project type should I start with to get the extension running? I have already tied /Framework/Bundle, Generic C++ Plug-in. How can I force the -flat_namespace in Xcode?

                                        But if you find out, could you post back here? It'd be nice to include alternative setups.

                                          I am sure that I remember an old thread where someone explained how to do a OSX extension. I think they said you had to link it to the framworkized Ruby that is under the SketchUp app directory (not the system Ruby that Apple installs.) .. If I recall correctly, that is.

                                          I'm not here much anymore.

                                            I didn't have to relink anything. But I'm not familiar with his scenario of XCode 4.4.
