如何在MakeFile（Eclipse）中添加库（header + .c）编译？

我正在开发一个项目，使用C++进行编码，以开发覆盖Raspberry Pi和Arduino之间的TCP/IP通信Modbus。如何在MakeFile（Eclipse）中添加库（header + .c）编译？

我有一个基本的例子，在树莓里工作的“hello world”。我想在我的Eclipse Project中添加libmodbus库（.h和.c文件），并测试提供的服务器单元测试。我已经在“路径和符号”（GNU C和GNU C++）和“包含”中添加了目录。

在MakeFile中，我添加了libmodbus文件部分的目录（#Include paths）。当我构建项目时，只有.h文件被编译，没有.c文件。该“modbus.h”是公认的，但它们就像“未定义的引用错误... ...（MODBUS fonctions）。

我已经测试了许多解决方案，但它并没有正常工作。

在感谢。提前

你可能需要添加-lmodbus您LDADDLIBS变量：

LDADDLIBS += -lmodbus -lpthread -lrt -lm -lstdc++

谢谢，我加了这条线，但它不工作'找不到-lmodbus' –

检查'/ usr/lib'中是否有'libmodbus.so' – igagis

不，我没有'libmodbus.so'任何地方。我刚刚在官方网站上下载了libmodbus文件 –

如何在MakeFile（Eclipse）中添加库（header + .c）编译？
