MCPP does not support UNC paths in includes

[Dwayne Boone]

It appears that mcpp does not support UNC paths for include directives. For example I have a file Test.h that is accesable via a UNC path:

E:\src\test>dir "\\BEAST\Beast Documents\Test.h"
Volume in drive \\BEAST\Beast Documents has no label.
Volume Serial Number is 6462-6FF5

Directory of \\BEAST\Beast Documents

03/12/2009  11:52 AM                 0 Test.h
               1 File(s)              0 bytes
               0 Dir(s)     289,890,304 bytes free

Now when I run mcpp on a file that just does "#include <Test.h>" I get the following:

E:\src\test>mcpp -I"\\BEAST\Beast Documents" Test.cpp
#line 1 "E:/src/test/Test.cpp"
E:/src/test/Test.cpp:1: error: Can't open include file "Test.h"
    #include <Test.h>
1 error in preprocessor.

But as I showed above Test.h is present in "\\BEAST\Beast Documents"

On my Windows systems, mcpp seems to work fine with UNC.

Would you inform me what type of mcpp you tested, such as version, compiler and build-type?

Any other user's informations on this problem are welcome too.

However, I'm now busy, sorry.  I'm going to move my dwelling, and can't connect to the Internet for a week from now on.  I'll check your informations when I get settled.

I am using v2.7.2 on Windows XP compiled with VS2005. I am not doing anything special wrt build just

cd mcpp-2.7.2/src
patch -p0 < ../noconfig/vc2005.dif
nmake /f ../noconfig/visualc.mak

I can then run mcpp on a file that is using a UNC path. IE the following works

E:\src\test>mcpp "\\BEAST\Beast Documents\Test.h"
#line 1 "//BEAST/Beast Documents/Test.h"
class Test
{
};

But I cannot use the UNC path in an include directive. This fails

E:\src\test>mcpp -I"\\BEAST\Beast Documents" Test.cpp
#line 1 "E:/src/test/Test.cpp"
E:/src/test/Test.cpp:1: error: Can't open include file "Test.h"
    #include <Test.h>
1 error in preprocessor.

Test.h is definitely present in "\\BEAST\Beast Documents" as is shown by the fact that running mcpp directly on it works.

Looked into this some more and the issue is that _stat call is failing for "\\BEAST\Beast Documents". It turns out that _stat does work not for for UNC paths if the path is just the share folder. If I use a extra dir, ie "\\BEAST\Beast Documents\include" then it works. I am not sure if there is anything that can be done about this.
