Using a string defined in project(.pro)
Is there a way to define build/version information in the project file and then use it in your application.
My application uses a version string as "1.23.4567" which i'm defining in my project file and using it to generate an opkg/ipk package (passing it to the CONTROL file).
I want to be able to use the same definition within my C code so that i can use it with qApp->setApplicationVersion()
currently i have the following information in my project(.pro) file
#added versioning information to project APPLICATION_VERSION="1.23.4567" DEFINES += APPLICATION_VERSION VERSION = $$APPLICATION_VERSION
But when I try to use the define i get the following
qDebug() << "APPLICATION_VERSION :" << QString( APPLICATION_VERSION ); APPLICATION_VERSION : "\u0001"
qDebug() << "APPLICATION_VERSION :" << APPLICATION_VERSION; APPLICATION_VERSION : 1
I've also tried
#added versioning information to project APP_BUILD=4567 APP_MINOR=23 APP_MAJOR=1 DEFINES += APP_MAJOR APP_MINOR APP_BUILD VERSION = $$APP_MAJOR"."$$APP_MINOR"."$$APP_BUILD
which results in the following:
qDebug() << "APPLICATION_VERSION :" << APP_MAJOR << "," << APP_MINOR << "," << APP_BUILD; APPLICATION_VERSION : 1 , 1 , 1
qDebug() << "APPLICATION_VERSION :" << QString("%1.%2.%3").arg( APP_MAJOR, 1, 10, QChar('0') ) .arg( APP_MINOR, 2, 10, QChar('0') ) .arg( APP_BUILD, 4, 10, QChar('0') ); APPLICATION_VERSION : "1.01.0001"
Is there a way to expose the version information that I've defined in my project file to use within my code?
Hi! The following thread has the solution: Use qmake variable in cpp file.
BTW, with Qbs it's as simple as:
.qbs - file:
cpp.defines: ["Something", "doStuff=1", 'WSS="something with whitespace"']
#ifdef Something qDebug() << "Something"; #endif qDebug() << QString("doStuff: %1").arg(doStuff); qDebug() << WSS;
@Wieland Thanks for the reference - that has worked for me.
Also, thanks for the Qbs information - i hadn't seen this before but will look into it
@SGaist - thanks for the info
I had previously tried something similar but I think it may have been the escaping of quotes which caught me out.
