编译 C++使用 cygwin 不会搜索提供的包含路径
我正在一棵树中工作，该树在我扔给它的任何 Unix 机器上都可以正常编译，但是 Cygwin 很困难，我不太确定从哪里开始。我有以下目录结构：
buildwin/
|-- main.cpp
|-- other project files
|-- include/
|-- tclap
|-- CmdLine.h
|-- other files (including CmdLine.cpp)
|-- eigen
|-- (appropriate files)
|-- rapidxml
|-- (appropriate files)
当我尝试编译它时，我从 g++ 中收到以下错误：
$ g++ main.cpp -lglut32 -lglu32 -lopengl32 -Iinclude/eigen -Iinclude/rapidxml -Iinclude/tclap
main.cpp:6:27: fatal error: tclap/CmdLine.h: No such file or directory
compilation terminated.
我知道它找到其他库（eigen 和 rapidxml）很好，因为如果我删除相应的包含标志，它会抛出一个错误，指出它找不到eigen或你有什么。
有问题的包含语句是：
// snip
#include <Eigen/StdVector>
#include <cmath>
#include <iostream>
#include <fstream>
#include <tclap/CmdLine.h>
// snip
想法？谢谢！
I am working within a tree that compiles fine on any Unix machine I throw it at, but Cygwin is being difficult and I'm not really sure where to start. I have the following directory structure:
buildwin/
|-- main.cpp
|-- other project files
|-- include/
|-- tclap
|-- CmdLine.h
|-- other files (including CmdLine.cpp)
|-- eigen
|-- (appropriate files)
|-- rapidxml
|-- (appropriate files)
When I try to compile this, I get the following error from g++:
$ g++ main.cpp -lglut32 -lglu32 -lopengl32 -Iinclude/eigen -Iinclude/rapidxml -Iinclude/tclap
main.cpp:6:27: fatal error: tclap/CmdLine.h: No such file or directory
compilation terminated.
I know it's finding the other libraries (eigen and rapidxml) fine because if I remove the respective include flags, it throws an error saying that it can't find eigen or what have you.
The include statement in question is:
// snip
#include <Eigen/StdVector>
#include <cmath>
#include <iostream>
#include <fstream>
#include <tclap/CmdLine.h>
// snip
Ideas? Thanks!

您指定 -Iinclude/tclap，然后包含
tclap/CmdLine.h，因此编译器会寻找include/tclap/tclap/CmdLine.h< /代码>。使用
-Iinclude，或包含不带路径的CmdLine.h。You're specifying
-Iinclude/tclap, then includetclap/CmdLine.h, so the compiler goes hunting forinclude/tclap/tclap/CmdLine.h.Either use
-Iinclude, or includeCmdLine.hwithout the path.使用
-Iinclude有效吗？您可能不需要显式添加include的子目录，因为您在#include语句的名称中引用了它们。Does using
-Iincludework? You probably don't need to be explicitly adding the subdirs ofincludebecause you refer to them in the names in the#includestatements.
