Question

更新最小工作示例

我在公共svn repo中创建了一个最小的工作示例。 Checkout来自trunk的proj文件夹，它有一个CMakeLists.txt和main.cpp（下面的代码已发布）。在trunk中我还有lib文件夹，它是实现类的静态库。这个类在我的主要使用。我在代理服务器后面，所以我在~/.subversion/server添加了全局代理设置。

预期行为：结帐项目后，执行cmake .并执行结帐 lib 并执行{{1}在构建我的make之前创建libmylib.a。最后main我的主要项目。

实际行为：不结帐 lib ，因此未构建make。错误讯息：

libmylib.a

我的问题是Makefile中的Makefile项目没有更新到SVN上的当前版本，甚至在开始时都没有检出。要构建ROS pkg，我使用externalproject_add()。

我正在研究catkin_tools 14.04，Ubuntu 2.8.12.2（以及ROS Indigo）。

My ROS pkg CMakeList：

您的配置看起来很好，CMakeLists.txt中似乎出现了一个小错误：项目（主要）应该出现在外部项目包含部分之前。希望这会有所帮助。

ExternalProject_Add初始svn co未执行
