[Insight-developers] itk/gdcm build errors on Fedora 12

[kent williams]

I don't know what you mean by 'fixing the path' -- where did you fix it? In
the source file? The CMakeLists.txt? Somewhere else?

The compiler errors come from these declarations in uuid.h:

/* UUID abstract data type */
struct uuid_st;
typedef struct uuid_st uuid_t;

this decares uuid_t as an structure that hasn't been defined.  It's an
opaque type.  You can't declare a variable of the type because the compiler
knows nothing about its structure.

More baffling is that if we're at a similar code revision, the errors are in
the HAVE_UUID_GENERATE block, and if I look at the header you attached, it
doesn't define uuid_generate.

I don't have access to Fedora 12, but what you probably need to do is find
out where uuid_st is defined -- it would need to be defined before calling
any declaration of a variable of type uuid_t.
