Mkbundle未能在OS上编译C#应用程序

Question

我已经干了几天了，虽然我很快就让Mono的mkbundle在Windows和Linux上创建了一个本机可执行文件，但我在OS上却没有这样做。

我使用Mono3.4.0，因为我需要.NET 4.5的支持，能够在OS上编译x86_64也很好。

目前，我使用以下简单的bash脚本来尝试mkbundle构建：

#!/bin/bash
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/lib/pkgconfig:/Library/Frameworks/Mono.framework/Versions/3.4.0/lib/pkgconfig
#PKG_CONFIG_PATH=/Library/Frameworks/Mono.framework/Versions/3.4.0/lib/pkgconfig

mkbundle bin/Release/Launcher.exe --static --deps -o bin/Release/OSXNative/Launcher.exe

我得到了下面的输出：

$ ./OSXNativeBuild.sh 
OS is: Darwin

我尝试过的事情：

• 我发现删除--静态参数允许mkbundle构建成功。但是，这只是转移到上面的问题到运行时，我希望它无论如何静态编译。
• Mono3.4.0发行说明提到现在Mac上的mkbundle必须始终链接到目标-C运行时。然而，我不知道如何做到这一点，这对我来说没有任何意义，因为我为什么要这样做。

我最终解决了问题所在--我看到了新的mkbundle属性需求和一些不匹配的体系结构设置。下面的脚本适用于我：

#!/bin/bash

# Notes:
# You will need the Mono SDK 3.x series as the 2.x SDK cannot build for 64bit architectures.
# It appears that Mono 3.x still cannot compile for 64bit without having to manually compile Mono yourself.
# Since we don't strictly need 64bit support the below forces a 32bit build.

# Ensure it can find pkg-config:
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/lib/pkgconfig:/Library/Frameworks/Mono.framework/Versions/3.4.0/lib/pkgconfig

# Force 32bit build and manually set some clang linker properties:
export AS="as -arch i386"
export CC="cc -arch i386 -lobjc -liconv -framework Foundation"

# Build:
mkbundle bin/Release/Launcher.exe --static --deps -o bin/Release/OSXNative/Launcher.exe
