Multiple include paths in mex

Question

I have a source file with headers in multiple directories that I'm compiling.

mex -v -IC:\working\tempInclude1 -IC:\working\tempInclude2 mexTest.cpp

returns

arguments = -IC:\working\tempInclude1 -IC:\working\tempInclude2

and works fine. But if I try to use the syntax below,

srcFile = 'mexTest.cpp';
ipath = ['-I' fullfile(pwd,'tempInclude1') ' -I' fullfile(pwd,'tempInclude2')];
mex('-v',ipath,srcFile)

it returns

arguments = -I"C:\working\tempInclude1 -IC:\working\tempInclude2"

and that double quote causes the command to fail. Any ideas? When I look at ipath, there is no quote in it.

You need to use two different variables or a cell array of paths:

path1 = ['-I' fullfile(pwd,'tempInclude1')];
path2 = ['-I' fullfile(pwd,'tempInclude2')];
mex('-v',path1,path2,srcFile)

or

 ipaths = {['-I' fullfile(pwd,'tempInclude1')], ['-I' fullfile(pwd,'tempInclude2')];}
 mex('-v',ipaths{:}, srcFile)

I suggest reading up on how command mode differs from function calling mode. matlab command syntax vs function syntax
