在取消生成"gr-ais“的CMake时找不到模块"mpir”

Question

我试图安装"gr-ais“，在使用CMake时遇到了一个错误：”无法找到MPIR (缺失: MPIRXX_LIBRARY MPIR_INCLUDE_DIR)"：

mavo@mavo:~/Dokumente/ais$ cmake gr-ais/
-- Build type not specified: defaulting to release.
-- Checking for module 'mpir >= 3.0'
--   No package 'mpir' found
-- Could NOT find MPIR (missing: MPIRXX_LIBRARY MPIR_INCLUDE_DIR) 
-- User set python executable /usr/bin/python3
-- Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython3.8.so (found suitable exact version "3.8.5") 
-- Extracting version information from git describe...

-- Configuring done
-- Generating done
-- Build files have been written to: /home/mavo/Dokumente/ais

因此，gr_ais无法工作：

mavo@mavo:~/Dokumente/ais$ ais_rx 
Traceback (most recent call last):
  File "/usr/local/bin/ais_rx", line 6, in <module>
    import ais
ModuleNotFoundError: No module named 'ais'

我也安装了mpir3.0 (https://github.com/wbhart/mpir/releases)、gnuradio同伴(3.8.1.0)、GMP 6.2.1和libgmp-dev (2:6.2.0+dfsg-4)。还有其他想法吗？

这解决了我的问题:我需要在/usr上安装gr-ais，而不是/usr/local。所以，只需键入cmake -DCMAKE_INSTALL_PREFIX=/usr gr-ais/，我认为在/use/本地python中找不到库.别忘了以前做make clean。

我也安装了更多的软件包：

sudo apt install -y cmake autoconf libtool pkg-config build-essential  libcppunit-dev swig doxygen liblog4cpp5-dev gnuradio-dev gr-osmosdr libosmogsm10  libosmocodec0 libosmogsm-doc libosmosdr0 libosmocodec-doc libosmosdr-dev libosmocoding0 libosmocoding-doc libosmocore libosmocore11 libosmocore-dev libosmocore-doc libosmocore-utils libosmoctrl0 libosmoctrl-doc

毕竟，只需做: make和sudo make ais_rx ist就可以用于sudo了。

，但这并没有解决缺少的mpir包。CMake还在抱怨，但是gr-ais似乎现在起作用了。
