llvm dev - Sep 2004 - [LLVMdev] MAXPATHLEN' undeclared (first use this function)

Hi,

I get below error:
---------------------------------
In file included from /usr/local/build/llvm/lib/System/platform/Path.cpp:23,
                 from /usr/local/src/llvm/lib/System/Path.cpp:27:
/usr/local/build/llvm/lib/System/platform/../Unix/Path.cpp: In member 
function
   `bool llvm::sys::Path::create_directory(bool)':
/usr/local/build/llvm/lib/System/platform/../Unix/Path.cpp:343: error: `
   MAXPATHLEN' undeclared (first use this function)
---------------------------------

MAXPATHLEN is on Interix defined in <limits.h>.

However, it doesn't seem to have any effect including it before any other 
header files in the system specific Path.cpp for Interix as seen above:
---------------------------------
#include <limits.h>

// Include the generic Unix implementation
#include "../Unix/Path.cpp"

...
---------------------------------

Any suggestions?

Henrik

A few things.

1. There's probably a #define that controls the definition of
MAXPATHLEN. You'd need to set that before you #include limits.h. I don't
know what the #define is, but this is a very common thing in these kinds
of headers.

2. There might just be an alias for MAXPATHLEN such as PATHLEN or
MAXPATH that is always defined. Have a look at limits.h

3. Since Interix is like POSIX, you might want to you _POSIX_PATH_MAX
instead.
