Question

我正在尝试在Snow Leopard上编译Macports，特别是文件src/macports1.0/get_systemconfiguration_proxies.c。这#include CoreFoundation/CoreFoundation.h #include CoreFoundation/CFBase.h，其中尝试到#include CoreServices/../Frameworks/CarbonCore.framework/Headers/MacTypes.h。现在，CoreServices是一个符号链接：

$ ls -l CoreServices
lrwxr-xr-x  1 root  wheel  62 Mar 25 17:15 CoreServices -> ../../System/Library/Frameworks/CoreServices.framework/Headers

所以我怀疑目标是到达../../System/Library/Frameworks/CoreServices.framework/Frameworks/CarbonCore.framework/Headers/MacTypes.h，这是一件非常好的事情：

$ ls -l ../../System/Library/Frameworks/CoreServices.framework/Frameworks/CarbonCore.framework/Headers/MacTypes.h 
-rw-r--r--  1 root  wheel  30291 Jun 24  2010 ../../System/Library/Frameworks/CoreServices.framework/Frameworks/CarbonCore.framework/Headers/MacTypes.h

但是，gcc不喜欢它：

In file included from $INCLUDE/CoreFoundation/CFBase.h:48,
                 from $INCLUDE/CoreFoundation/CoreFoundation.h:38,
                 from get_systemconfiguration_proxies.c:42:
$INCLUDE/CoreServices/../Frameworks/CarbonCore.framework/Headers/MacTypes.h:20:42: error: CarbonCore/ConditionalMacros.h: No such file or directory

这让我怀疑

（编辑：但是Tom Zych指出我怀疑是错误的，因为我没有读完错误消息。叹息。）

gcc可能无法解析符号链接，而是过分巧妙地将CoreServices/../Frameworks/CarbonCore.framework/Headers/MacTypes.h折叠为Frameworks/CarbonCore.framework/Headers/MacTypes.h，这肯定不存在：

$ ls -l Frameworks/CarbonCore.framework/Headers/MacTypes.h
ls: Frameworks/CarbonCore.framework/Headers/MacTypes.h: No such file or directory

我是否有可能正确解释错误？如果是这样，有没有办法在gcc到cd之前跟踪符号链接..？

Answer 1

错误消息以：

结尾

$INCLUDE/CoreServices/../Frameworks/CarbonCore.framework/Headers/MacTypes.h:20:42: \
error: CarbonCore/ConditionalMacros.h: No such file or directory

它似乎能够读取并开始处理MacTypes.h，因为它指的是其中的行号。它找不到的文件是CarbonCore/ConditionalMacros.h。

我猜CarbonCore应为CarbonCore.framework。为什么这个问题不久就出现了，我不知道。也许这是最近的改变。

gcc包括路径和符号链接
