我在用C语言写我的第一个应用程序,但是它似乎找不到头文件(我按照自述文件中的说明进行了安装):
#include <stdio.h>
#include <stdlib.h>
#include <ftdi.h>
int main (int argc, char *argv[])
{
int ret;
struct ftdi_context = *ftdi;
struct ftdi_version_info version;
if ((ftdi = ftdi_new()) == 0)
{
fprintf(stderr, "ftdi_new failed\n");
}
else {
fprintf(stderr, "Success\n");
}
return 0;
}
但它在这里找到了它:
ollieb@ursus ~/Documents/BitBang $ locate ftdi.h
/home/ollieb/.local/share/Trash/files/libftdi/libftdi/ftdipp/ftdi.hpp
/home/ollieb/.local/share/Trash/files/libftdi/libftdi/src/ftdi.h
/home/ollieb/Applications/libftdi1-1.3/build/doc/html/group__libftdi.html
/home/ollieb/Applications/libftdi1-1.3/build/doc/man/man3/ftdi.h.3
/home/ollieb/Applications/libftdi1-1.3/build/doc/man/man3/ftdi.hpp.3
/home/ollieb/Applications/libftdi1-1.3/ftdipp/ftdi.hpp
/home/ollieb/Applications/libftdi1-1.3/src/ftdi.h
/usr/include/libftdi1/ftdi.h
/usr/include/libftdi1/ftdi.hpp
当我尝试编译时,出现了文件找不到的错误(当我在代码库文件夹中运行示例时,它们可以正常运行):
ollieb@ursus ~/Documents/BitBang $ make
make bitbang
make[1]: Entering directory '/home/ollieb/Documents/BitBang'
cc -Wall -g bitbang.c -o bitbang
bitbang.c:3:18: fatal error: ftdi.h: No such file or directory
compilation terminated.

make[1]: Leaving directory '/home/ollieb/Documents/BitBang'

ftdi.h
副本(有很多个)位于非标准位置,编译器只在某些地方搜索头文件。你需要在编译器命令中添加路径,最可能的是-I/usr/include/libftdi1
