我有一个内置的C静态库（Antlr 3 C库）。它已正确安装并正常工作（即，我可以正常运行gcc -o parser lexer.c parser.c -lantlr3c）。
然而，在Xcode中，我收到错误。我在“其他链接器标志”构建设置中添加了-lantlr3c。
ld: library not found for -lantlr3c
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-gcc-4.2 failed with exit code 1
我在此处找到的其他几个问题（1，2，3，4）通常都有针对Xcode 3的答案。我正在使用Xcode 4.1，在iOS静态库项目中。我正在构建单元测试。
编辑：根据@LaceySnr的要求，来自详细gcc和Xcode错误的输出。
gcc的输出：
$ gcc -v -o parser.o BFMathParser.c BFMathLexer.c -lantlr3c -arch i386

答案 0 :(得分：0)
在导航器中单击您的项目，选择适当的目标，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。
您还必须删除-lantlr3c标记。
答案 1 :(得分：0)
您可以在其他链接器标志中使用它，但您还需要确保该路径也在库搜索路径中。
还要确保使用正确的配置构建（调试/发布/无论如何） - 您可以指定不同的库来链接每个库，因此如果您将其设置为调试但是您正在构建发布它显然不会链接。
答案 2 :(得分：0)
当您在Mac上使用gcc测试此lib时，您使用的是x86版本。 iOS链接器找不到它，因为您可能没有构建库的arm版本。
