我是使用 make 的新手,我正在尝试运行此处给出的 Qt 密度演示的 RInside 示例:http: //dirk.eddelbuettel.com/blog/2011/03/25/。我已将代码保存到以下文件中:
main.cpp Makefile qtdensity.cpp 包含/qtdensity.h
我正在运行 Ubuntu 13.10,我安装了 R、Rcpp 和 Inside。当我去终端并运行
> make -f Makefile
我得到错误
make: *** No targets. Stop.
请让我知道如何进行。
谢谢
我看不到如何对第一个答案提出跟进,所以我必须扩展我的问题:
我刚刚创建了这些文件,并且能够在 main.cpp、qtdensity.cpp、qtdensity.h 和 qtdensity.pro 上运行 qmake,但是当我尝试运行 make 时,出现以下错误:
