为iPhone编译FreeType？ [英] Compiling FreeType for iPhone?

问题描述

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。

I'm using FreeType on Windows, Linux and OSX without a single problem, and now I was to port my tech to IOS... And I can't find a way to have FreeType compiled for it.

起初我试图将每个FT文件放入我的项目中，但这显然不起作用。

At first I tried to drop every FT file into my project, but that clearly didn't work.

然后我尝试在此教程之后创建一个静态库。
虽然我无法测试它是否适用于arm目标，但它不适用于模拟器目标。

Then I tried to make a static library following this tutorial here. While I can't test if it worked for the arm target, it doesn't work for the simulator target.

尝试链接构​​建的库时进入XCode，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）
，这很好，因为命令lipo -info libfreetype-simulator.a告诉我该文件是为x86_64构建的。
我尝试用./configure --i386-apple-darwin配置它，这里是日志。
但是，最终的结果是x86_64。

When trying to link the built library into XCode it says "libfreetype-simulator.a, file was built for archive which is not the architecture being linked (i386)" and that's ok because the command "lipo -info libfreetype-simulator.a" tells me that the file was built for x86_64. I tried configuring it with "./configure --i386-apple-darwin", here's the log. But still, the resulting arch was 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。

How in the world can I build freetype for i386, iphone simulator? I really have no clues.

推荐答案

我用的是链接在cxa的答案中。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：

I used the link in cxa's answer. However it is very out of date, and my configure line did not fit in a comment. For armv7, compiling with the 6.1 SDK, with a minimum version of 5.1, without bzip2, you want something like:

./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，如果留下则会发出来自Apple的警告电子邮件。另请注意，各种路径名已更改。

Note the lack of -mdynamic-no-pic which would otherwise produce a linker warning, and a warning email from Apple, if left in. Also note that various pathnames have changed.
