cygwin中的gcc编译器找不到X窗口目录

Question

我正在尝试编译一个项目，该项目在我的 /usr/include 目录中包含来自 X11 的各种文件。它可以在远程 linux 机器上正常编译，但是当我尝试运行 make 文件时出现以下错误：

$ make clean; make
rm -f xrobot.o mobile_base.o arm.o eye.o object.o 4D_math.o Xkw/Canvas.o Xkw/Sli
der.o Xkw/Xkw.o lib/simulator.a *~
cd ./Xkw; make; cd ..; \

make[1]: Entering directory `C:/cygwin/home/Gene/roger/mmRogerSpring2014/RogerSi
mulator/Xkw'
gcc -c -g  -I. -I/usr/include/X11 -I/usr/X11R6/include Canvas.c
Canvas.c:9:22: fatal error: X11/Xos.h: No such file or directory
compilation terminated.
make[1]: *** [Canvas.o] Error 1
make[1]: Leaving directory `C:/cygwin/home/Gene/roger/mmRogerSpring2014/RogerSim
ulator/Xkw'
gcc -c -g -I. -I/usr/X11R6/include -I/usr/include/X11 -I./include  xrobot.c
In file included from xrobot.c:11:0:
Xkw/Xkw.h:12:27: fatal error: X11/Intrinsic.h: No such file or directory
compilation terminated.
make: *** [xrobot.o] Error 1

但是，我知道文件在那里，我可以做到

$ cat /usr/include/X11/Xos.h

然后读取文件。

这是我的制作文件：

# replace this with the top of your X11 tree
# X11 = /exp/rcf/share/X11R5
X11 = /usr/X11R6

ROGERINCDIR = ./include

    ar r $(ROGERLIB) $(OFILES1) $(XKWOFILES)

编辑：我已将 make 文件顶部的 X11 变量更改为 /usr/include 而不是 /usr/X11R6。没什么区别。

编辑 2：这是上述替代包含路径的错误。

$ make clean; make
rm -f xrobot.o mobile_base.o arm.o eye.o object.o 4D_math.o Xkw/Canvas.o Xkw/Sli
der.o Xkw/Xkw.o lib/simulator.a *~

Answer 1

您应该将 X11/Xos.h 包含为：

#include

如果您将其包含为：

#include "X11/Xos.h"

它将相对于源文件进行搜索，而不是在 -I 目录中。

这可能是问题所在。
