c++ - 安装自己的 block 后 Gnuradio 崩溃

Question

我正在尝试为 gnuradio 安装自己的 Block。我完成了这个(http://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorial_GNU_Radio_in_C++)教程。但是在第 5 步安装时，我遇到了一些问题。

我安装了它，但我没有在 gnuradio-companion 中看到 Block。 我添加了路径:

export PYTHONPATH=/usr/local/lib/python2.7/site-packages/

export GRC_BLOCKS_PATH=/usr/local/share/gnuradio/grc/blocks/

现在我可以看到 block 了:但是如果我想使用它，gnuradio-companion 就会崩溃。

^[[A^[[BFatal Python error: PyThreadState_Get: no current thread
Abort trap: 6

Gnuradio 版本:3.7.10.1

操作系统:OS X El Capitan

可能是什么问题？错误/缺少路径？程序有误？

/edit2:要添加一个 block ，用 python 编写可以正常工作(使用教程:http://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorial_GNU_Radio_in_Python)

/edit: 当我安装它时，我在使用 cmake 时收到很多警告:

当 GNU Radio 和您的模块链接到不同的 Python 库时，就会发生这种情况。

在 OSX 上，通常有一个系统安装和另一个来自 Homebrew 或 MacPorts 的安装。尝试将所有内容链接到 Homebrew/MacPorts 库。

您似乎在 /opt/local 中安装了 Python。使用 cmake 重新配置您的模块并将 PYTHON_LIBRARY 和 PYTHON_INCLUDE_DIR 指向/opt 中的安装。
