[Scons-users] qt5 question: how to handle header files in separate directories?

[B.W.H. van Beest]

Hello Dirk,

Thanks for your response. It pointed me to how to approach the problem,
although I ended up with a completely different solution.
As it turned out, the solution seems to be quite simple, and no
additional functions need to be available.
To share my solution, have a look below the ==== line.

It would be even simpler, and very natural,  if the function Moc5(...)
could take a list of files ...
Would that be possible?


Kind Regards,
Bertwim


================
The source tree of the library I'm building looks like:

..../MYPROJECT/include/<dir>/*.h             // header files exposing API
..../MYPROJECT/src/<dir>/*.cpp , *.h        // sources files + internal
headers.

where <dir> is one of a set of directories, together containing the
source files for the library to built.
 
The scons files are:

..../MYPROJECT/src/SConstruct
..../MYPROJECT/src/<dir>/SConscript

The SConstruct file has the qt5 tool initialisation code, as described
in the qtt tool guidel.
The SConscript files have a code snippet like:' ('gexplorer' is just one
of the directories <dir>)

#-----------------------------------------------------------------------------
# Source files
cppsources = Glob( '*.cpp' )
qrcsources = Glob( '*.qrc' )

# Assume all header files in "../../include to be moc-ed ...
mocsources = Glob( '../../include/gexplorer/*.h' )
mocresults = ""
for sss in mocsources:
    mocresults += localenv.Moc5( sss )

# Targets: link and install
lib = localenv.SharedLibrary( target='gexplorer', source = cppsources +
qrcsources + mocresults )
dir = localenv.Install( localenv['DESTLIB'], source = lib )

localenv.Default( dir )
-----------------------------------------------------------------------------------
