ExternalProject_Add 初始 svn co 未执行

Question

更新最小工作示例

我在 public 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（代码在 posted 下面）。在主干中我还有 lib 文件夹，它是实现 class 的静态库。这个class在我的main中使用。我在代理后面，所以我在 ~/.subversion/server 添加了全局代理设置。

预期行为：在检出 proj 后执行 cmake .，同时检出 lib 并执行 make 以在构建我的 main 之前创建 libmylib.a。最后 make 我的主要项目。

实际行为：不签出 lib，因此未构建 libmylib.a。错误信息：

原版post

我有一个 ROS 包 (pomdp_planner) 链接到一个 Makefiel 项目 (project_appl)。我在 SVN 上有两个项目，但位置不同（我在代理后面）。如果我重新签出 ROS 节点并构建它，它无法下载 Makefile 项目，因此构建在链接阶段失败。如果我在所需位置手动签出 Makefile 项目，则会构建 ROS PKG

我的问题是 externalproject_add() 中的 Makefile 项目没有更新到 SVN 上的当前版本，甚至一开始都没有签出。为了构建 ROS pkg，我使用 catkin_tools.

我正在研究 Ubuntu 14.04、cmake 2.8.12.2（和 ROS Indigo）。

我的 ROS pkg CMakeList：

您的配置看起来不错，您的 CMakeLists.txt 中似乎出现了一个小错误：project(main) 应该出现在外部项目包含部分之前。希望这有帮助。
