Xcode Plugin for Win32 c/c++ compiler

Win32Plugin gives Xcode, Apple's development environment, the possibility to fully drive a GNU c/c++ cross-compiler for MSWindows (95 and above). Win32Plugin works with versions 2.5, 3.1.*, and 3.2 of Xcode.

Win32Plugin allows a single Xcode project to build executables for MacOS X and MSWindows platforms.

Installation

Download file Developer.zip that contains the plugin and install its content, folder Developer, in "$HOME/Library/Application Support" on your computer. Your plugin should sit in your computer as:
$HOME/Library/Application Support/Developer/3.1/Xcode/Plug-ins/Win32Plugin.pbplugin
replacing 3.1 by 3.2 if using Xcode 3.2, or by 2.5 if using Xcode 2.5.
Install a cross-compiler or use your own:
- In the likely case that you don't have already on your Mac a GNU c/c++ Win32 cross-compiler, download files cross.zip and libintl.zip. Move the content of cross.zip, folder cross, to /usr/local on your computer. This compiler must be in /usr/local/cross to run properly. It is gcc/g++ 3.4.6, and is for Intel Macs only. Move the content of libintl.zip, three files, to /usr/local/lib on your computer (unless you already have these files).
- If you already have a working GNU Win32 c/c++ cross-compiler, adapt and enter these commands in a Terminal window to reflect its name and location:
```
defaults write com.apple.Xcode win32gxxpath  /full/path/to/mingw32-g++
defaults write com.apple.Xcode win32gccpath  /full/path/to/mingw32-gcc
defaults write com.apple.Xcode win32arpath  /full/path/to/mingw32-ar
```
Optionally, for the curious, the full source code of Win32Plugin is available as an Xcode project with two targets, Win32Plugin25 to be used only with Xcode 2.5, and Win32Plugin31 only with Xcode 3.1 or 3.2.

Usage

For your first use of Win32Plugin, download this Xcode project hello that contains 4 targets for MacOS X, Darwin + X11, and MSWindows, with the same source file. Targets 25helloWin32 and 3.xhelloWin32 are to be used with Xcode 2.5 and 3 respectively. Quit and restart Xcode for it to load the plugin. If using Xcode 3, delete target 25helloWin32, and conversely for Xcode 2.5. You should be able to build each of the 3 remaining targets. The xxhelloWin32 target will produce a working MSWindows executable program.

The easiest would be to modify the hello Xcode project by adding more elaborate source files, and possibly pre-compiled libraries. This project contains FLTK 1.1.8 header files and libraries for MacOS X, Darwin+X11, MSWindows. You can replace them by your own, or by other FLTK versions.

Alternatively, add a Win32 target to an existing project of yours by the "New target..." command, or create a new Win32 project by the "New project..." command. The Assistant window allows to choose Win32 program or library. Add the relevant c/c++ source files to the newly created win32 target. After that, open the Info window of this target, go to the Rules view, and modify the System C rule: change "using: GCC System Version (4.0)" into "using: Win32 C/C++". Next, go to the Build view, and set the compiler & linker settings, namely header and library search paths and Win32Plugin's own ones (see table below).

MSWindows system libraries (e.g., ole32.dll) can be added to your target as follows:

with Xcode 3.1/3.2: set option WIN32_SYSTEMLIBS to -Wl,-lname1,-lname2
with Xcode 2.5: set option OTHER_WIN32LD_FLAGS to -lname1 -lname2

Win32Plugin can produce and use libraries as well as executables.

Win32Plugin's compiler and linker settings (for Xcode 3.1/3.2)

Use HEADER_SEARCH_PATHS and LIBRARY_SEARCH_PATHS as with Mac OS X targets.
Setting "Base SDK" from section "Architectures" must be set to "Current Mac OS".

Win32Plugin-specific settings	Usage
GCC_GENERATE_DEBUGGING_SYMBOLS	when on, adds "-g" to compilation and link operations
OPTIMIZE	to add "-O1", "-O2", or "-O3" to compilations
WARNING_AS_ERROR	when on, adds "-Werror" to compilations
ALL_WARNINGS	when on, adds "-Wall" to compilations
OTHER_WIN32_FLAGS	to add any additional options to compilations
USE_WIN32_GUI	when on, adds "-mwindows" to the link command
WIN32_SYSTEMLIBS	set this to "-Wl,-lname1,-lname2,..." to link with named system libraries
OTHER_WIN32_LDFLAGS	to add any additional options to the link command
