• 準備運行Hello_Triangle。

null@dev:~/opengles3/opengles3-book-master/build/Chapter_2$ cd Hello_Triangle/ null@dev:~/opengles3/opengles3-book-master/build/Chapter_2/Hello_Triangle$ ls CMakeFiles? cmake_install.cmake? Hello_Triangle? Makefile null@dev:~/opengles3/opengles3-book-master/build/Chapter_2/Hello_Triangle$ ./Hello_Triangle 段錯誤 (核心已轉儲)

• 設置環境變量也沒有解決。

null@dev:~/opengles3/opengles3-book-master/build/Chapter_2/Hello_Triangle$ export LD_LIBRARY_PATH=/opt/Imagination/PowerVR_Graphics/PowerVR_SDK/SDK_4.0/Builds/Linux/x86_64/Lib/

• 段錯誤 (核心已轉儲) 解決辦法：

Linux默認給一個進程分配的棧空間大小為8M。c++申請變量時，new操作申請的變量在堆中，其他變量一般在存儲在棧中。因此如果數組開的過大變會出現這種問題。可以用指令ulimit -s XXXX來申請更大的棧空間。 null@dev:/opengles3/opengles3-book-master/build/Chapter_2/Hello_Triangle$ ulimit -a null@dev:/opengles3/opengles3-book-master/build/Chapter_2/Hello_Triangle$ ulimit -s? 102400 null@dev:/opengles3/opengles3-book-master/build/Chapter_2/Hello_Triangle$ sudo ./Hello_Triangle
