TBB link with C++
TBB link with C++
我正在尝试在HPCG基准测试中使用TBB进行一些测试。但是到目前为止,我没有成功编译该程序。我收到如下错误:

collect2: error: ld returned 1 exit status
make: *** [bin/xhpcg] Error 1
Compile instruction look like this:
make
/usr/bin/g++ -DHPCG_NOMPI -DHPCG_NOOPENMP -I./src -I./src/GCC_TBB -O3 -ltbb -std=c++11 -ffast-math -ftree-vectorize -ftree-vectorizer-verbose=0 -fopenmp testing/main.o src/CG.o src/CG_ref.o ....
我从英特尔下载并安装了最新的源代码。另外,我已经在编译时使用了 -ltbb 和 -std=c++11,并在代码中包含 tbb 文件。到目前为止,我无法弄清楚问题所在。以前有没有人遇到过这样的事情 英特尔 TBB?我假设这是图书馆链接的东西,但我无法弄清楚
尝试在 -o 之前插入 "-ltbb -std=c++11",它应该可以工作!
Patroklos Patroklou的回答没有帮助,所以我把-ltbb
放在命令的末尾,它起作用了。
