Question

我在Windows，Linux和OSX上使用FreeType没有任何问题，现在我将我的技术移植到IOS ...... 而且我找不到为它编译FreeType的方法。

起初我尝试将每个FT文件放入我的项目中，但这显然不起作用。

然后我尝试在this tutorial here之后创建一个静态库。虽然我无法测试它是否适用于手臂目标，但它不适用于模拟器目标。

当试图将构建的库链接到XCode时，它说“libfreetype-simulator.a，文件是为存档而构建的，而不是被链接的架构（i386）” 这没关系，因为命令“lipo -info libfreetype-simulator.a”告诉我该文件是为x86_64构建的。我尝试使用“./configure --i386-apple-darwin”，here's the log进行配置。但是，最终的结果是x86_64。

我可以在世界上如何为i386，iphone模拟器构建freetype？我真的没有线索。

Answer 1

我使用了link in cxa's answer。但是它已经过时了，我的配置行不适合评论。对于armv7，使用6.1 SDK进行编译，最低版本为5.1，不使用bzip2，您需要以下内容：

./configure '--without-bzip2' '--prefix=/usr/local/iphone' '--host=arm-apple-darwin' '--enable-static=yes' '--enable-shared=no' 'CC=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' 'CFLAGS=-arch armv7 -pipe -std=c99 -Wno-trigraphs -fpascal-strings -O2 -Wreturn-type -Wunused-variable -fmessage-length=0 -fvisibility=hidden -miphoneos-version-min=5.1 -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/usr/include/libxml2/ -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/' 'AR=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar' 'LDFLAGS=-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/ -miphoneos-version-min=5.1'

请注意缺少-mdynamic-no-pic否则会产生链接器警告，以及来自Apple的警告电子邮件（如果留下）。另请注意，各种路径名已更改。

我在尝试为iOS编译FreeType时遇到了这个项目：https://github.com/cdave1/freetype2-ios

只需下载，在xcode中打开，然后编译即可。：）

希望这对尝试编译iOS的其他人有帮助。

我已使用此链接成功编译了FreeType for iOS：http://librocket.com/wiki/documentation/BuildingFreeTypeForiOS

Answer 4

对于Xcode 5，gcc已移动位置，因此配置应为：

./configure --without-zlib --without-png --without-bzip2 '--prefix=/usr/local/iPhone' '--host=arm-apple-darwin' '--enable-static=yes' '--enable-shared=no' 'CC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang' 'CFLAGS=-arch armv7 -pipe -std=c99 -Wno-trigraphs -fpascal-strings -O2 -Wreturn-type -Wunused-variable -fmessage-length=0 -fvisibility=hidden -miphoneos-version-min=6.1 -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/libxml2/ -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/' 'AR=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar' 'LDFLAGS=-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/ -miphoneos-version-min=6.1'

可以通过运行来找到CC的位置：

$ xcrun -find -sdk iphoneos clang

Answer 5

对于在Xcode 6.1上具有最小目标7.1的iOS SDK 8.1，这可以工作：

./configure --without-zlib --without-png --without-bzip2 '--prefix=/usr/local/iPhone' '--host=arm-apple-darwin' '--enable-static=yes' '--enable-shared=no' 'CC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang' 'CFLAGS=-arch armv7 -pipe -std=c99 -Wno-trigraphs -fpascal-strings -O2 -Wreturn-type -Wunused-variable -fmessage-length=0 -fvisibility=hidden -miphoneos-version-min=7.0 -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.1.sdk/usr/include/libxml2/ -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.1.sdk/' 'AR=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar' 'LDFLAGS=-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.1.sdk/ -miphoneos-version-min=7.0'

Answer 7

This shell script适用于我，x86_64。你可能需要看看。

我用它来编译freetype2.5.5，并得到了armv7，arm64，i386，x86_64。当然它也是一个胖胖的静态库。

Answer 8

为了使freetype能够顺利编译，传递变量＆＃39; CC＆＃39;，＆＃39; CFLAGS＆＃39; LDFLAGS＆＃39;和＆＃39; AR＆＃39;作为configure和不作为环境变量的参数。

在某些时候configure运行机器的本机gcc，如果你有LDFLAGS＆＃39;这指向iphone SDK会导致它失败。将变量传递给configure似乎解决了这个问题。
