I am trying to implement a project file to build my project conditionally. In
my case the condition is the host architecture, either 32 bit linux or 64 bit
linux. I tried something like this:
message($$QMAKESPEC)
linux-g++-32 {
message( "have 32 bit linux")
}
linux-g++-64 {
message("have 64 bit linux")
}
I took this from qmake Advanced Usage available in assistant.
That fragment does not work. In fact only the first call to message prints
Project MESSAGE:
which seems to mean that the variable QMAKESPEC has null value and the two
conditions are not met.
I am using qt-4.8.0.
How can I implement such conditional building based on the host architecture?
Thanks for any help,
Zen
