RInside編譯：制定目標

Question

我是使用make的新手，我嘗試運行此處給出的Qt密度演示的RInside示例：http://dirk.eddelbuettel.com/blog/2011/03/25/。我已保存代碼到下列文件：

的main.cpp 的Makefile qtdensity.cpp 包括/ qtdensity.h

我運行Ubuntu 13.10，我已經安裝了R，RCPP和內部。當我去到終端，運行

> make -f Makefile 

我得到的錯誤

make: *** No targets. Stop. 

請讓我知道如何着手。

謝謝

我看不出怎麼問的後續行動的第一個答案，所以我不得不延長我的問題：

我剛纔創建的文件，並能在main.cpp中，qtdensity.cpp，qtdensity.h運行的qmake和qtdensity.pro其工作，但，當我試圖運行make，我得到以下錯誤：

大量的R - 相關錯誤...

Qt的例子不同，因爲它使用Qt。您需要通過.pro文件創建Makefile本身來始終始終。證人：

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 
-rw-rw-r-- 1 edd edd 1532 Dec 27 18:38 qtdensity.h 
-rw-rw-r-- 1 edd edd 2378 Feb 11 20:14 qtdensity.pro

edd@max:~/git/rinside/inst/examples/qt$ qmake  ## creates Makefile

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

這當然自述此目錄中還描述了 ...
