Hello,
I just write to signal a bug and its solution. I installed the 14.04 LTS
ubuntu version and installed the xen version through synaptic. As I'm
developping modules for Xen I also installed the xen dev package. The
installed Xen version is 4.4.2.
I tried to compile one of my C files including xenctrl.h but I got the
following errors :
In file included from ../modules/gntring/libgntring4.c:12:0:
/usr/include/xenctrl.h:122:14: error: use of enum ‘xc_error_code’ without
previous declaration
typedef enum xc_error_code xc_error_code;
^
/usr/include/xenctrl.h:122:41: error: invalid type in declaration before
‘;’ token
typedef enum xc_error_code xc_error_code;
^
/usr/include/xenctrl.h:1759:6: error: using typedef-name ‘xc_error_code’

enum xc_error_code {

/usr/include/xenctrl.h:122:28: note: ‘xc_error_code’ has a previous

typedef enum xc_error_code xc_error_code;
^
/usr/include/xenctrl.h:1770:8: error: using typedef-name ‘xc_error_code’

enum xc_error_code code;

/usr/include/xenctrl.h:122:28: note: ‘xc_error_code’ has a previous
declaration here
typedef enum xc_error_code xc_error_code;
I looked at xenctrl.h and the typedef is put before the declaration of the
enum :
typedef enum xc_error_code xc_error_code;
...
enum xc_error_code {
XC_ERROR_NONE = 0,
XC_INTERNAL_ERROR = 1,
XC_INVALID_KERNEL = 2,
XC_INVALID_PARAM = 3,
XC_OUT_OF_MEMORY = 4,
/* new codes need to be added to xc_error_level_to_desc too */
};
I swapped the two declarations and that works just fine :
enum xc_error_code {
XC_ERROR_NONE = 0,
XC_INTERNAL_ERROR = 1,
XC_INVALID_KERNEL = 2,
XC_INVALID_PARAM = 3,
XC_OUT_OF_MEMORY = 4,
/* new codes need to be added to xc_error_level_to_desc too */
};
typedef enum xc_error_code xc_error_code;
Best regards,
