why does APP_BUILD_VERSION have different value on different platform?

[LongQi]

the same code base,

on Linux:

#ifndef _APP_VERSION_H_
#define _APP_VERSION_H_

/*  values come from cmake/version.cmake
 * BUILD_VERSION related  values will be 'git describe',
 * alternatively user defined BUILD_VERSION.
 */

/* #undef ZEPHYR_VERSION_CODE */
/* #undef ZEPHYR_VERSION */

#define APPVERSION                   0x20200
#define APP_VERSION_NUMBER           0x202
#define APP_VERSION_MAJOR            0
#define APP_VERSION_MINOR            2
#define APP_PATCHLEVEL               2
#define APP_TWEAK                    0
#define APP_VERSION_STRING           "0.2.2"
#define APP_VERSION_EXTENDED_STRING  "0.2.2+0"
#define APP_VERSION_TWEAK_STRING     "0.2.2+0"

#define APP_BUILD_VERSION 0.1.0+0-65-g0222c98b6b9f


#endif /* _APP_VERSION_H_ */

and on windows;

      
#ifndef _APP_VERSION_H_
#define _APP_VERSION_H_

/*  values come from cmake/version.cmake
 * BUILD_VERSION related  values will be 'git describe',
 * alternatively user defined BUILD_VERSION.
 */

/* #undef ZEPHYR_VERSION_CODE */
/* #undef ZEPHYR_VERSION */

#define APPVERSION                   0x20200
#define APP_VERSION_NUMBER           0x202
#define APP_VERSION_MAJOR            0
#define APP_VERSION_MINOR            2
#define APP_PATCHLEVEL               2
#define APP_TWEAK                    0
#define APP_VERSION_STRING           "0.2.2"
#define APP_VERSION_EXTENDED_STRING  "0.2.2+0"
#define APP_VERSION_TWEAK_STRING     "0.2.2+0"

#define APP_BUILD_VERSION 0222c98b6b9f


#endif /* _APP_VERSION_H_ */

    

this is very strange. How to fix this?

Hi,

This is generated by git and can differ. The main thing is that it uniquely identifies an app version and should be treated as a string, so the format is normally not relevant. See https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/build/version/index.html#use_in_code 

[LongQi]

I understand but you did not answer my question. how to make them consistent?

[Einar Thorsrud]

Hi,

As you see in the link I pasted, this comes from "git describe --abbrev=12 --always". The output of this depend on the repository that is checked out and the state of it. It depend on the state of the Git repo (tag, another commit, etc). This is a feature of Git and not our SDK, and I do not have any suggestinos for modifying it.

[LongQi]

then how to change the command from git describe --abbrev=12 --always to 

git rev-parse --short=12 HEAD

where is it?

[Einar Thorsrud]

This should come from git.cmake which is where the git_describe function is defined. (But it seems odd that you should see a difference between Windows and Linux in itself, I would think that there is a difference in the two repos that explains the idfference you are seeing).
