mex 无法识别内联答案

【问题标题】：mex doesn't recognize inlinemex 无法识别内联

【问题描述】：

我正在尝试编译a matlab wrapper for libdc1394，这是一个用于火线相机的库。我收到一个奇怪的错误，涉及头文件中的一些内联函数。我正在使用 gcc-4.6 开发 ubuntu 12.04。我已经成功编译了其他 mex 文件。这个包装器在 mac 中也很难编译。

/usr/local/MATLAB/R2012b//bin/mex dc1394mex.c  `pkg-config --libs --cflags libdc1394-2` -o dc1394.mexa64

Warning: You are using gcc version "4.6.3-1ubuntu5)".  The version
         currently supported with MEX is "4.4.6".
         For a list of currently supported compilers see:

有什么想法吗？

【问题讨论】：

尝试添加-std=c99
mex: -std=c99 不是有效选项。

标签： c matlab gcc mex

【解决方案1】：

Simons 的提议是正确的。我不知道的唯一问题是您不能将 cflags 直接提供给 mex。您必须更改您的 mexopts.sh 文件。我还必须删除 -ansi 标志，因为它与 c99 相矛盾。

【讨论】：

非常有用！你救了我的早晨！我只需要弄清楚如何将 mex 指向我的 mexopts.sh 文件。 mex 选项 -f 成功了。

【解决方案2】：

如何在命令行通过CFLAGS修改指定C99：

mex -v -largeArrayDims CFLAGS="\$CFLAGS -std=C99" dc1394mex.c
