Question

我正在使用

$ g ++ --version g ++（Ubuntu 4.8.4-2ubuntu1~14.04.3）4.8.4

在LinuxMint 17.2框上

尝试从https://github.com/briand/gr-scan.git

构建gr-scan

与

gnuradio 3.7.10.1-1~ubuntu14.04.1myriadr amd64 GNU Radio Software Radio Toolkit

我发现人们处理g ++类似的破坏各种包，或者在他们自己的代码中谜题。但是，我还没有找到一个适用的明确解决方案。

似乎有一些内在的伏都教是罪魁祸首。

在我的情况下，错误是这样的：

g++ -DVERSION="\"gr-scan 2012082301\"" -std=c++11 -Wall -I/usr/local/include -largp -lgnuradio-pmt -lgnuradio-runtime -lgnuradio-blocks -lgnuradio-fft -lgnuradio-filter -lgnuradio-osmosdr -lboost_system -O2 -Wno-unused-function -o gr-scan main.cpp

有一个简单的解决方案吗？

Answer 1

这绝对不像GNU Radio问题，更像是GCC / g ++ / stdlibc ++安装的根本错误。确保您没有安装冲突，或者在构建gnuradio软件包时使用的标志与您现在使用的标签不兼容。

事实上，std=c++11似乎确实存在疑问。

g ++内在无法转换
