包括X code外部C库 [英] Including external C library with Xcode
本文介绍了包括X code外部C库的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个内置C固定库（在ANTLR的3 C库）。这是正确的安装和工作（即我可以运行的gcc -o解析器lexer.c parser.c -lantlr3c 就好了）。
在X code，但是，我得到一个错误。我在其他连接标志构建设置添加 -lantlr3c 。
LD
命令/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-gcc-4.2失败，退出code 1
我在这里找到（<一个其他几个问题href=\"http://stackoverflow.com/questions/3344120/including-a-static-library-in-a-x$c$c-project\">1, 2 ，的3 ，<一个href=\"http://stackoverflow.com/questions/1471968/x$c$c-linker-error-library-not-found-for-ladmobdevice\">4)一般有答案瞄准X code三级。我用X code 4.1，在iOS的静态库项目。我目前正在建设的单元测试的东西。
编辑：作为的要求@LaceySnr，从冗长的gcc和X code的错误输出
从GCC的输出：
$ gcc的-v -o parser.o BFMathParser.c BFMathLexer.c -lantlr3c -arch i386的
使用内置的规格。

解决方案
在测试这个lib目录与海湾合作委员会在Mac上使用的是它的的x86版本。 iOS的链接器没有找到它，因为你可能没有建库的ARM版。
I have a built C static library (the Antlr 3 C library). It is installed properly and works (i.e., I can run gcc -o parser lexer.c parser.c -lantlr3c just fine).
In Xcode, however, I get an error. I've added -lantlr3c in the "other linker flags" build setting.
ld: library not found for -lantlr3c
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-gcc-4.2 failed with exit code 1
Several other questions I've found here (1, 2, 3, 4) generally have answers targeting Xcode 3. I'm using Xcode 4.1, in an iOS static library project. I'm currently building the unit test stuff.
EDIT: As requested by @LaceySnr, the output from verbose gcc and Xcode's error.
The output from gcc:
$ gcc -v -o parser.o BFMathParser.c BFMathLexer.c -lantlr3c -arch i386
Using built-in specs.

解决方案
When you test this lib with gcc on your Mac you are using the x86 version of it. The iOS linker does not find it because you probably did not build the arm version of the library.
