如何使libusb库对另一个程序可见？

问题描述

我正在尝试编译库。为了编译，我需要。我已经下载，配置，制作和安装到 / usr / local / lib 。但是当我尝试编译 hidapi 时，它看不到 libusb-1.0 ：

（在Synology NAS上进行编译）

解决方案

$ c> / usr / local / lib ， pkg-config 将找不到您的安装，除非您设置 PKG_CONFIG_PATH 正确

尝试执行：

  export PKG_CONFIG_PATH =$ PKG_CONFIG_PATH：/ usr / local / lib / pkgconfig
  

尝试构建您的代码

I am trying to compile hidapi library. In order to compile that, I need libusb-1.0. I've downloaded that, configured, made and installed to /usr/local/lib. But when I try to compile hidapi, it doesn't see libusb-1.0:

How can I fix that?

(compilation happens on Synology NAS)

解决方案

Since you installed to /usr/local/lib, pkg-config will not find your installation unless you set PKG_CONFIG_PATH appropriately

Try running:

export PKG_CONFIG_PATH="$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig"

in your shell and then re-attempting to build your code
