[SOLVED] How can I test whether a .pri file has already been included
-
I have multiple subfolders of a project. Each of these subfolders contains a .pri file describing what files need to be included. There is some cross-referencing when a subfolder needs a component from another. A simple and silly description of this problem is as follows:
in /root/sub0/sub0.pri:
include( /root/sub1/sub1.pri )in /root/sub1/sub1.pri:
include( /root/sub0/sub0.pri )in /root/root.pri
include( /root/sub0/sub0.pri )
include( /root/sub1/sub1.pri )When I compile this after running qmake, I get problems with:
"overriding commands for target ------"
and warnings about multiple definitions.
Is there a way in a qmake project file to test if a .pri file has already been included somewhere else??

You can use same approach as in c/c++ headers. Defines. Just test for define and if not defined then define it and do stuff.
-
what is the syntax for that in a .pri file?

I think "isEmpty":http://developer.qt.nokia.com/doc/qt-4.7/qmake-function-reference.html#id-141c6ec1-7a4a-42f2-bd82-1e8a7ea79bdb will help you

Thank you Denis. I took your advice and expanded it a bit. Here's the template that I used for protecting my .pri files from multiple inclusion:
@
!contains( included_modules, $$PWD ) {
included_modules += $$PWD
message( "Including $$PWD" ).pri body
HEADERS, SOURCES, QT *=, include(), etc...
} else {
message( "Skipping $$PWD: already included" )
}
@Thanks for the help
