我试图得到我砖的平板电脑cpuid，我有这个代码，当我通过terminal在ubuntu上执行它，它会给出以下错误：第5行：附近意外的令牌附近的语法错误'（'行5：'int主（无效）”
我该如何解决这个问题？
#include <libusb-1.0/libusb.h> #include <stdio.h> #include <stdint.h> int main(void) { unsigned char data[64]; int received_length; int r = 1; libusb_context* ctx = NULL; libusb_device_handle* dev_handle = NULL; libusb_init(&ctx); dev_handle = libusb_open_device_with_vid_pid(ctx, 0x0955, 0x7820); if(dev_handle) { r = libusb_bulk_transfer(dev_handle, 0x81, data, sizeof(data), &received_length, 10000); if (r == 0) { if(received_length == 8) { printf("uid: 0x%08X%08X\n", *((uint32_t*)data+1), *((uint32_t*)data+0)); } else { r = 1; printf("Error: We got %d bytes of data insetad of the 8 bytes we expected...\n", received_length); } } else { printf("Error: USB read failed!\n"); } libusb_release_interface(dev_handle, 0); } else { printf("Error: Failed to open device!\n"); } libusb_exit(ctx); return r; } 您需要编译该程序并运行可执行文件。 如果程序在foo.c ，则用下面的代码进行编译：
gcc foo.c -o foo
然后你执行它：
./foo
您不能直接运行C源文件 – C不是脚本语言。
