包含外部C库和Xcode

我有一个内置的C静态库（Antlr 3 C库）。 它被正确安装和工作（即，我可以运行gcc -o parser lexer.c parser.c -lantlr3c就好）。

在Xcode中，但是，我得到一个错误。 我在“其他链接器标记”构build设置中添加了-lantlr3c 。

 ld: library not found for -lantlr3c Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-gcc-4.2 failed with exit code 1 

我在这里find的其他一些问题（ 1,2,3,4 ）通常有针对Xcode 3的答案。我在iOS静态库项目中使用Xcode 4.1。 我目前正在build立unit testing的东西。

编辑：按照@LaceySnr的要求，输出从详细的海湾合作委员会和Xcode的错误。

Answer 1

在导航器中单击您的项目，select适当的目标，然后展开“ 链接的框架和库”部分。 单击加号，单击添加其他… ，然后浏览到您的静态对象。

你也必须删除-lantlr3c标志。

Answer 2

您可以在其他链接器标志中使用它，但是也需要确保path在库searchpath中。

还要确保你正在构build正确的configuration（debugging/释放/无论） – 你可以指定不同的库链接每一个，所以如果你已经设置为debugging，但你正在build设释放它显然不会链接。

Answer 3

当你在你的Mac上用gcctesting这个库时，你正在使用它的x86版本。 iOS连接器没有find它，因为您可能没有构build库的arm版本。
