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:

很多与 R 相关的错误...

Qt 示例不同,因为它使用 Qt。您总是需要从 .pro 文件创建 Makefile 本身开始。见证:

edd@max:~/git/rinside/inst/examples/qt$ ls -l        ## no Makefile
total 28
drwxrwxr-x 2 edd edd 4096 Dec 27 18:38 cmake
-rw-rw-r-- 1 edd edd  518 Dec 27 18:38 main.cpp
-rw-rw-r-- 1 edd edd 5953 Dec 27 18:38 qtdensity.cpp

-rwxrwxr-x 1 edd edd 76666 Feb 14 15:02 qtdensity

这当然也在这个目录的自述文件中描述......
