G ++固有不能轉換

Question

我使用

$ G ++ --version G ++（Ubuntu的4.8.4-2ubuntu1〜14.04.3）4.8.4

在LinuxMint 17.2箱

試圖建立從https://github.com/briand/gr-scan.git

GR-掃描與

中的gnuradio 3.7.10.1-1〜ubuntu14.04.1myriadr AMD64的GNU Radio軟件無線電工具包

我發現人們處理g ++類似破損的各種軟件包，或在他們自己的代碼中的謎題。但是，我還沒有找到適用的明確解決方案。

看來，一些與內在的巫術是巫術的罪魁禍首。

在我的情況下，錯誤是這樣的：

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

有一個簡單的解決方案嗎？

Answer 1

這絕對看起來不像GNU無線電問題，更像是你的GCC/g ++/stdlibC++安裝有根本錯誤。確保你沒有衝突的安裝，或者當構建gnuradio軟件包時使用的標誌與你現在使用的軟件不兼容。

事實上，std=c++11似乎確實可疑。
