Qt 5.8交叉編譯通過arm-none-linux-gnueabi faild？

Question

我下載臂無-Linux的gnueabi從2011年CodeSourcery的版本，設置後的路徑和配置與此命令

須藤的./configure \ -opengl ES2 -no-XCB \ - 釋放-silent \ - 繼續\ -opensource -confirm許可證\ -prefix $ DEVICE_PREFIX \ -hostprefix $ HOST_PREFIX \ -sysroot $系統根目錄\ -device $ TARGET_DEVICE \ -device選項CROSS_COMPILE = $ {CC} \ -qt- libpng \ -qt-libjpeg \ -nomake examples \ 個-nomake測試

得到這個錯誤：

Answer 1

你的編譯日誌表明，它試圖用gold鏈接，但該命令沒有被發現。錯過的庫和對象文件後來的錯誤大概源於這個錯誤。

gold是GNU工具鏈中相對較新的一個，並且您使用的是相當舊的版本（gcc 4.6.1），所以我建議您將工具鏈升級到最新版本，除非您有非常好的理由這樣做。

Answer 2

Qt對於工具鏈選擇頗有見地。有一個list of supported compilers它不包括基於GCC 4.6的東西。鑑於Qt現在需要C++ 11支持，所以使用古代編譯器工作的機會受到嚴重限制。

Linaro提供nice toolchains供下載。你有沒有任何理由不使用它？另外，您也可能需要在您的BBB上額外使用一些軟件，因此您可能會使用像Debian這樣的發行版或Buildroot或Yocto等構建工具來生成圖像。 BeagleBone Black是一款主流平臺，提供基本上針對嵌入式平臺的任何支持。

TL; DR版本：更新您的工具鏈或您的構建環境。 Qt不是簡單的庫。
