Hi,

I am trying to compile freeciv 2.5.10 from source, with Qt gui, like:

./configure --enable-aimodules=yes --enable-client=qt --enable-shared --disable-nls

It stops with:
> configure: error: selected client 'qt' cannot be built: Missing Qt5 development files

I've got qt5 from homebrew, it is linked by "brew link --force qt", I've got qtpath, qmake and other qt binnaries in my PATH (because of the linking), I did "export PKG_CONFIG_PATH=/usr/local/Cellar/qt/5.10.1/lib/pkgconfig/", but the configure script stops with the message above.

I've tried also:
./configure --enable-aimodules=yes --enable-client=qt --enable-shared --disable-nls --with-qt5-includes=/usr/local/Cellar/qt/5.10.1/include/ --with-qt5-libs=/usr/local/Cellar/qt/5.10.1/lib, again, with no success.

I did not manage to google the answer, and here is this post.

Please help.
Thank you in advance.

Can I see config.log produced by the configure attempt?

Please consider the attachement.
I've grepped it for qt and QT, there are apparently many errors.

Dear cazfi,

Thank you for inspiring me.

The very first error in the log was, "error: Qt requires a C++11 compiler and yours does not seem to be that."

I googled it, and got this:
https://stackoverflow.com/questions/378 ... make-error

Solved by:
export CXXFLAGS=-std=c++11

Configure completed, see the second log.

However, make failed at freeciv-qt:

This topic, https://stackoverflow.com/questions/189 ... or-project, says about origings of a similar problem, "can't split a templated class into a .cpp and a .h file".
However, my level in c is helloworld tops, and I'd rather not try fixing it myself.

Can you report this to the bugtracker at http://www.hostedredmine.com/projects/f ... issues/new ?

Meanwhile, you can test if it goes through if you disable audio support at configure time with '--disable-sdl-mixer' option.

Opened the ticket myself, so I can attack the fix I'm making there. http://www.hostedredmine.com/issues/734798

Thank you.

I've disabled SDL and got another error, apparently at the very final linking:

I've tried googling it, the answers are quite different, too much of a dark magic for me.

I've managed to compile freeciv 2.5.8, with
./configure --enable-aimodules=yes --enable-client=qt --enable-shared --disable-nls --disable-sdl-mixer

It works. However, the problem that initially brought me to the qt client is still present.
http://forum.freeciv.org/f/viewtopic.ph ... 99&p=97418

Namely, units do not move smoothly, they teleport after waiting for animation delay times number of steps. Apparently, this is not a gtk bug, its something else. Noteworthy, the problem is not present in linux.

Can you test if the patch there fixes the build problem with audio enabled for you?
