在C中编写我的第一个应用程序,它似乎无法找到头文件(我按照自述文件中的说明安装):

#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

这是当我尝试编译时发生的事情,它说无法找到该文件(当我在代码库文件夹中运行示例时,它们运行正常):

ollieb@ursus ~/Documents/BitBang $ make
make bitbang
