QtChooser allows you to select your version of Qt among those installed.
However, this tool is no longer supported upstream and will not be
available for Qt6.
By default, our Qt installations are done in
${LOCALBASE}/lib/qt${QT_VERSION} as recommended.
We have added symbolic linking for the main binaries to
${LOCALBASE}/bin with the suffix -qt5.

## ### PROCESSING
|
|
##
|
|
## This file is processed three ways:
|
|
## - to replace %%variables%% with the intended values
|
|
## - to replace @tag with ## or blank as appropriate
|
|
## - to filter out lines containing ##
|
|
##
|
|
## The resulting "minified" script is used as pkg-install or pkg-deinstall
|
|
## script in the package.
|
|
##
|
|
## Lines with @tag at the beginning should be read as conditional;
|
|
## multiple @tags are read as "and", so the **rest** of the line
|
|
## only ends up in the resulting script when all the @tags are true.
|
|
##
|
|
## The file is formatted with lots of spaces between the @tags and script
|
|
## so that the shell-script itself can be read in column 24,
|
|
## e.g. v--- here
|
|
##
|
|
## To read the script, try `grep -v '##' pkg-change.in | cut -c 25-`
|
|
##
|
|

|
|
## ### ABOUT
|
|
##
|
|
## A Qt module should be listed in QtCore/qconfig-modules.h only once,
|
|
## and only if that is needed (e.g. if it has a qconfig-*.h of its own).
|
|
## In case 1 (listed), update the target file by appending and sorting:
|
|
## - echo the new line and existing contents if any
|
|
## - .. pipe to sort -u
|
|
## - .. then move the sorted-uniqued output to the config-modules.h
|
|
## In case 2 (unlisted), update the target file by deleting a line
|
|
##
|
|
## Removing QtCore *may* leave behind an empty file, and in that case
|
|
## clean up the config file and directories entirely.
|
|
##
|
|
## A module with versionable binaries (like "designer" which might have
|
|
## a Qt4, Qt5 and Qt6 version).
|
|
##
|
|
##
|
|
## On deinstall, we need QT_INCDIR separately, so define variables $qi and $qc
|
|
## differently from install (which needs only $qc).
|
|
@deinstall qi="%%QT_INCDIR%%"
|
|
@deinstall qc="$qi/QtCore/qconfig-modules.h"
|
|
@install qc="%%QT_INCDIR%%/QtCore/qconfig-modules.h"
|
|
qm="%%QT_MODNAME%%"
|
|
##
|
|
## Distinguish the pkg step and call the relevant shell functions defined above.

|
|
