Qtlua for Qt5.4.0 on Windows [Solved]

[MTCA]

I have to work on project based on QtLua. Currently, I am using Qt5.4.0 on Windows 7 OS. As I am naive to this environment and as there are very few reference sites available for QtLua on Win platform, I am unable to integrate both Qt5.4.0 and QtLua. I tried using libqtlua-2.0, but couldn't succeed. If anyone has tried doing so, please state the steps you have followed.

Hi and welcome to devnet,

I haven't used that library yet but if you explain what problems you are currently encountering (error message etc.) more forum users might be able to provide some help

[MTCA]

I am currently having Qt5.4.0 in my system. Following are the steps which I followed:

1. download the libqtlua-2.0 from http://download.savannah.gnu.org/releases/libqtlua/
2. Extract and cmake the file.
3. (Step where I am facing the problem):

C:\libqtlua-2.0\bld>make
[ 1%] Generating moc_qtluaqtlib.cpp
moc: Cannot open options file specified with @
QCommandLineParser: argument list cannot be empty, it should contain at least th
e executable name

make[2]: *** [src/moc_qtluaqtlib.cpp] Error 1
make[1]: *** [src/CMakeFiles/qtlua.dir/all] Error 2
make: *** [all] Error 2

C:\libqtlua-2.0\bld>

My Question is: Am I doing it correctly? Or missing some steps?

[MTCA]

Now, I have tried doing the same with Qt 5.0.2 and the error report generated is as follows:

Looks like in on one place there's a return statement where it shouldn't and a call to a function that doesn't seem to exists in the version of lua you are building against

[MTCA]

Thank you. This time, I have tried it with Lua 5.2(in earlier case it was Lua 5.3). The build which was getting stuck at 59% is now completed but now it is showing some new issues:

While doing cmake of libqtlua 2.0, it doesn't generate any error message, neither there is any failure in configuration and generation. But it does generate warning message :
"Looking for include file dlfcn.h
Looking for include file dlfcn.h - not found". Can this be the main cause of above errors?

[SGaist]

Looks like it's not linking to the QtWidget module

[MTCA]

Yes. I think you are right. Not only QtWidget module, but I think it is not linking to QtCore and QtXml modules as well (because while cmaking, I need to explicitly give the path of this 3 modules). But I do not understand what can be the problem! Am I doing cmake incorrectly or is it because of the compiler which I am using?

[MTCA]

Solved!!!

1. Qt 5.4.1-mingw-open source.
2. Libqtlua 2.0
3. Lua 5.1
   Earlier, I was trying to compile lbqtlua using mingw which I installed explicitly in the system, as , I was unaware about the existence of mingw in the tools provided by Qt. It was the reason of above errors.

[SGaist]

Great !

I forgot that usual suspect… It's a tricky one…

Thanks for sharing !

Since you have it working now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)
