独立的Rmath。h在本机C/ c++程序[2]

According to R-admin.pdf, I built the standalone Rmath library on my Mac. The first test program seemed compiled and linked well, but generated an error message. The followings are my procedures:

根据R-admin。我在我的Mac上建立了一个独立的Rmath库。第一个测试程序似乎被编译并链接得很好，但是产生了一个错误消息。以下是我的流程:

$ cc -o test test.c -I /library/frameworks/r.framework/headers 
-L/users/ed/downloads/r-2.13.1/src/nmath/standalone/ -lRmath -lm
$ ./test
dyld: Library not loaded: libRmath.dylib
  Referenced from: .....
  Reason: image not found
Trace/BPT trap
$

Thanks in advance.

提前谢谢。

I found a way to compile and link C code including Rmath.h. When you choose default installation, the path for the header is /library/frameworks/r.framework/headers, and the path for the library is /library/frameworks/r.framework/libraries.

我找到了一种方法来编译和链接C代码，包括Rmath.h。当您选择默认安装时，头文件的路径是/library/framework /r.framework/header，而库文件的路径是/library/framework /r.framework/libraries。

$ gcc -I/library/frameworks/r.framework/headers -c test.c

$ gcc -L/library/frameworks/r.framework/libraries test.o -lRmath -o progname

Single line implementation is also convenient:

单行实现也很方便:

$ gcc -I/library/frameworks/r.framework/headers test.c \
-L/library/frameworks/r.framework/libraries -lRmath -o progname

I found that Objective-C program can include standalone Rmath.h as well. Implementation is as follows: (name of the objective-c program is 'test.m.')

我发现Objective-C程序可以包含独立的Rmath。h。实现如下:(objective-c程序的名称是'test.m.')

$ gcc -framework Foundation -I/library/frameworks/r.framework/headers test.m 
-L/library/frameworks/r.framework/libraries -lRmath -o progname

I'm not a mac guy, but you need to ensure your program finds libRmath.dylib. On Linux you would set LD_LIBRARY_PATH...
