Auto increment build number for all platform (windows, linux and android)

liewjls

Hi,

I have a piece of code which will compile for all 3 platforms (windows, linux and android). I'm trying to keep track all the changes have gone into the each of the platforms. I did google, there's quite a few suggestion using the batch script for windows and bash script for linux. But now i'm stuck for Android version.

I have a script for window and linux and configured .pro file of the project,

#This is to auto generate the build number and build timestamp
build_nr.target = $$PWD/build_number.h
linux-g++-32{
build_nr.commands = cd $$PWD; chmod +x build_number.sh; $$PWD/build_number.sh
}
win32{
build_nr.commands = $$PWD/build_number.bat
}

build_nr.depends = FORCE
QMAKE_EXTRA_TARGETS += build_nr
PRE_TARGETDEPS += $$PWD/build_number.h
}

they are working but either on of it doesn't work when i tried to compile and generate APK (for android) no matter i build on windows or linux. Anyone have any idea how can i do the same thing for the Android platform?

Thanks.

Regards,
jenny

Unfortunately I'm unable to help, in fact, I'd like to ask you to share the contents of build_number.bat and build_number.sh

Hi @liewjls,

I haven't done any Qt Android development myself (yet), but looking at qmake's spec files, there's a separate android platform value which you should be able to use scope an Android-specific build-number script, such as:

android {
    build_nr.commands = <whatever you do to update Android resources>
}

I hope that helps.

Cheers.

what is the content of the whole pro file?
I guess you are sharing some output/intermediate folders among the different target build platforms?

Hi all,
Thanks for all suggestion.

@raven-worx I actually found out when I use the contains(QMAKE_HOST.os,Windows) in my pro file, it works on all platforms (no matter i build Android on Windows or Linux).

QT += core
QT -= gui

CONFIG += c++11
VER_MAJ=1
VER_MIN=0


QT_varfile = ""
for(var, $$list($$find($$list($$enumerate_vars()), ^(VERSION*|VER_MAJ*|VER_MIN*|DEFINES*).*$))) {
    line = $$var "$$eval($$var)"
    QT_varfile += $$join(line, "=")
}

write_file($$absolute_path("VARIABLES.txt", $$OUT_PWD), QT_varfile)


contains(QMAKE_HOST.os,Windows) {
    message("Host is windows")
    build_nr.target = extra
    build_nr.commands = $$PWD/build_number.bat $$VER_MAJ $$VER_MIN "$$cat($$OUT_PWD/build.txt)"
    build_nr.depends = FORCE
    QMAKE_EXTRA_TARGETS += build_nr
    PRE_TARGETDEPS += extra
}
else {
    message("Host is linux")
    build_nr.target = extra
    build_nr.commands = chmod +x $$PWD/build_version.sh; $$PWD/build_version.sh $$VER_MAJ $$VER_MIN
    build_nr.depends = FORCE
    QMAKE_EXTRA_TARGETS += build_nr
    PRE_TARGETDEPS += extra
    build_nr.target = $$OUT_PWD/version.h
}


TARGET = qtConsole
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

SOURCES += main.cpp

HEADERS += $$OUT_PWD/build_number.h

But I got a problem now. When i build my APK, the script will run twice. Anyone can help me to resolve this please?

@VRonin yes, not a problem. I did google around (sorry, i lost track with the links), come out with this

build_number.sh

@echo off
cd /d %dirPath%
set /a VERSION_BUILD=0

REM Read values from file
for /f "tokens=*" %%S in (VARIABLES.txt) do set %%S
echo Script has been run %VERSION_BUILD% time(s)

set /a VERSION_MAJOR=%1
set /a VERSION_MINOR=%2
set /a VERSION_BUILD+=1

set VERSION_STR=%VERSION_MAJOR%.%VERSION_MINOR%.%VERSION_BUILD%

REM Write new values to file
break > VARIABLES.txt
set VERSION >> VARIABLES.txt

for /F "usebackq tokens=1,2 delims==" %%i in (`wmic os get LocalDateTime /VALUE 2^>NUL`) do if '.%%i.'=='.LocalDateTime.' set ldt=%%j
set ldt=%ldt:~0,4%-%ldt:~4,2%-%ldt:~6,2% %ldt:~8,2%:%ldt:~10,2%:%ldt:~12,6%

echo #define TIMESTAMP  "%ldt%" > version.h
echo #define VER_STR "%VERSION_STR%">> version.h

build_number.sh

#!/bin/bash
dir="$PWD"
versionFile=$dir"/VARIABLES.txt"

. $versionFile

echo "VERSION"$VERSION
echo "VERSION_BUILD:"$VERSION_BUILD
echo "VERSION_MAJOR:"$VERSION_MAJOR
echo "VERSION_MINOR:"$VERSION_MINOR
echo "VERSION_STR:"$VERSION_STR

VERSION_BUILD=$((VERSION_BUILD+1))

VERSION_MAJOR=$1
VERSION_MINOR=$2
VERSION_STR=$VERSION_MAJOR"."$VERSION_MINOR"."$VERSION_BUILD

#Update the new value to the file.
echo -e "VERSION="$VERSION"\nVERSION_MAJOR="$VERSION_MAJOR"\nVERSION_MINOR="$VERSION_MINOR"\nVERSION_BUILD="$VERSION_BUILD"\nVERSION_STR="$VERSION_STR | tee $versionFile

today=`date +%Y-%m-%d" "%H:%M:%S`

echo -e "#define VERS_STR "\"$VERSION_STR\" "\n#define TIMESTAMP  "\"$today\" | tee version.h

My scripting skills isn't great, any comments to help me improve these 2 scripts that would be great.

thanks.
