Installation on Gentoo: QT3, QT4 and moc

Asked by kwaito

Hi,

I am using Gentoo Linux, and I have both QT3 and QT4 installed. The tagaini install script goes well, until it uses the 'moc' command. It gives this result:

/usr/qt/3/bin/moc -Isrc -I/usr/include/qt4 -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4/QtSql -I/usr/include/qt4/QtNetwork -o src/sqlite/moc_qsql_sqlite.cc src/sqlite/qsql_sqlite.h
Qt meta object compiler
moc: Invalid argument
Usage: moc [options] <header-file>
        -o file Write output to file rather than stdout
        -f[file] Force #include, optional file name
        -p path Path prefix for included file
        -i Do not generate an #include statement
        -k Do not stop on errors
        -nw Do not display warnings
        -v Display version of moc

The problem is that the used 'moc' command is the QT3 one, not the QT4. It is strange, because the '/usr/bin/moc' is the correct version (QT4), so the script uses instead '/usr/qt/3/bin/moc'.

I solved the problem by doing a temporary symlink from '/usr/qt/3/bin/moc' to '/usr/bin/moc' but it is not a very pretty solution.

It is the first time I use scons, so I do not know if the problem comes from Gentoo, scons, QT or tagaini, maybe you can help me ;-)

Hello, and thanks for your report!

It looks like the problem comes from the scons detection of Qt. I suspect that maybe you have a QTDIR environment variable that points to your Qt3 directory, which may confuse scons. In any way, I think setting the QTDIR environment variable to your Qt4 installation would solve your problem.

 Actually the current build process is not really pretty, I'd like to replace it by something cleaner but there is no better candidate than scons at the moment I'm afraid.

Apart from this problem, did the compilation complete successfully, and were you able to use the software as expected? I have never tried to build it on Gentoo so far.

I tried your way: I typed 'export QTDIR=/usr' and it worked. Thanks !

The compilation went fine, but I had these warnings:

- when I type 'scons release=yes lang=fr'
scons: warning: Two different environments were specified for target sqlite/moc_qsql_sqlite.cc,
        but they appear to have the same action: $QT4_MOC $QT4_MOCFROMHFLAGS $QT4_MOCINCFLAGS -o $TARGET $SOURCE

- and when tagaini builds the JMDict, sometimes 2 or 0 results are found:

I can execute the program without problems, but when I want to print some cards in a PDF file, the font for the English/French translations is really ugly. Does tagaini use a default system font ?

This is "normal", and due to my lack of understanding of scons. Not a
problem for building though.

This is nothing to worry neither - these issues come from the JMdict
and do not interfere with Tagaini. They are here as a reminder for me
to signal them upstream, I should just remove them from regular
builds.

This is weird however - the font should actually be the same as the
one on-screen. Tagaini uses the default system font for both display
and printing. Be aware that some PDF renderers behave strangely
sometimes. I suggest you try to print directly on a printer and check
if the result is still ugly - if the printed result is conform to what
you seen on the PDF screen rendering, would you mind sending me a
screenshot of it?

Unfortunately, I do not have access to a printer directly, so I have to generate PDFs and then send them to someone, but as soon as I can use a printer without the PDF step, I will tell you.
