Question

我从this site下载了用于MATLAB的jpeg_toolbox，然后从here下载了JPEG编译器工具。我按照说明为Mac配置了整个（UNIX *）。

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

mex jpeg_read.c

MATLAB返回以下错误：

Error using mex
Undefined symbols for architecture x86_64:
  "_jpeg_CreateDecompress", referenced from:
      _mexFunction in jpeg_read.o
  "_jpeg_destroy_decompress", referenced from:
      _mexFunction in jpeg_read.o

      _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，你们中的任何人都已经得到了我需要的mexmaci64吗？

我这样解决了：

brew install libjpeg

我在/usr/local/lib找到了库，所以在MATLAB上我移动到包含必须编译的.c文件的文件夹中，我跑了：

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

将jpeg_read.c编译为mexmaci64 for MATLAB
