为MATLAB编译jpeg_read.c作为mexmaci64 [英] Compile jpeg_read.c as mexmaci64 for MATLAB

问题描述

我从下载了MATLAB的jpeg_toolbox此站点，然后从此处下载JPEG编译器工具.我按照说明在Mac(UNIX *)上进行了整体配置.

I downloaded the jpeg_toolbox for MATLAB from this site, then downloaded the JPEG compiler tools from here. I followed the instruction to configure the whole for Mac (UNIX*).

现在，我将需要编译包含在MATLAB的第一个链接中的jpeg_read.c和jpeg_write.c，因为该工具箱不提供mexmaci64文件.但是，当我尝试:

Now, I would need to compile the jpeg_read.c and jpeg_write.c contained into the first link for MATLAB, because the toolbox does not provide the mexmaci64 files. However when I try to:

mex jpeg_read.c

MATLAB返回以下错误:

MATLAB returns the following error:

Error using mex
Undefined symbols for architecture x86_64:

      _mexFunction in jpeg_read.o

      _mexFunction in jpeg_read.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

如何编译程序?否则，你们中有人已经得到了我需要的mexmaci64吗?

How can I compile the program? Otherwise, does any of you have already got the mexmaci64 I would need?

推荐答案

我这样解决:

brew install libjpeg

我在/usr/local/lib中找到了库，因此在MATLAB上，我移到了包含必须编译的.c文件的文件夹，然后运行了:

I found the libraries in /usr/local/lib so on MATLAB I moved into the folder that contained the .c files that had to be compiled and I ran:

mex jpeg_read.c "/usr/local/lib/libjpeg.a"
mex jpeg_write.c "/usr/local/lib/libjpeg.a"
