[MINC-users] ON Building the ezminc examples

[Vladimir S. FONOV]

Hello Everybody,


I found the source of this problem in minc.h header (part of minc
distribution). Inside there are some definitions of functions
surrounded by usual.

#ifdef __cplusplus
extern "C" {
#endif /* __cplusplus */

... blah ...

#ifdef __cplusplus
}
#endif /* __cplusplus */


but, some functions are defined in minc_compat.h which doesn't have
this preprocessor macros.

The quick fix for ezminc to compile is to edit file
minc_io/minc_1_rw.h and replace #include <minc.h> with

extern "C" {
#include <minc.h>
}


But Ideally minc.h should be fixed instead.


P.S. Strangely enough problem doesn't seem to manifest itself with gcc
4.3 and older.
