我正在尝试将 libusb-1.0 库与Nsight Eclipse一起使用。我按照以下步骤进行操作：

  1. 下载 libusb-1.0 压缩包并安装在主机（Ubuntu）中。

  2. 按照 libusb 安装结束时给出的说明：

    Libraries have been installed in:
    /usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:

  - Add LIBDIR to the `LD_LIBRARY_PATH' environment variable

During execution:

  - Add LIBDIR to the `LD_RUN_PATH' environment variable

During linking:

  - Use the `-Wl,-rpath -Wl,LIBDIR' linker flag
  - Have your system administrator add LIBDIR to `/etc/ld.so.conf'

我添加了以下内容：

  • 'LIBDIR' 和 libusb.-1.0.so 菜单下的文件路径 Tool -> Settings -> NVCC Linker -> Libraries -> Library search path(-L)
  • LD_LIBRARY_PATH 和 LD_RUN_PATH 环境变量
  • NVCC编译器下的libusb.h路径->包含->包含路径(-l)
  • -lusb-1.0 在 NVCC Linker -> Miscellaneous -> Other flag 下

当我在 Nsight Eclipse 中构建项目时，控制台中出现以下错误。

make all

我该如何解决？

我能够在 libusb 开发邮件列表的帮助下解决我的问题。libusb 库应该为 64 位主机上的目标配置。

我必须为目标 arm-linux-gnueabihf 配置库，并且必须禁用 udev。所以，我使用了命令，

./configure --host=arm-linux-gnueabihf --prefix=/usr --disable-static --disable-udev && make && make install

我能够正确配置 libusb 并且现在可以编译。
