[Kde-bindings] Fwd: Qyoto/Kimono: A 64 bit unsafe function, build trouble on Debian unstable

[Richard Dale]

Hi Kaare

Thanks for the bug report - I'll forward it to the kde-bindings at kde.org 
mailing list. I'm not sure what the problem with the forum on the qyoto site 
is about, but once we've done a release it will be nice to use the forum to 
discuss programming issues.

Hi Richard

This mail is regarding the Qyoto/Kimono Project.

First I wanted to post in the forums on http://cougarpc.net/qyoto, but got an 
error about not having a referencing post.  Instead I used the contact form, 
but the mail bounced:

Finally I found your e-mail address on lists.kde.org.  I hope it works. :-)

Now to my reason for writing:  I tried compiling Qyoto (checked out from svn 
on 21 May) on my EM64T based Debian unstable system, and ran into the 
following problem when running make (after running "cmake ."):

[  2%] Building CXX object CMakeFiles/qyoto.dir/src/qyoto.o
/home/kaare/source/qyoto/src/qyoto.cpp: In function 'long int 
QyotoHash(void*)':
/home/kaare/source/qyoto/src/qyoto.cpp:1706: error: cast from 'void*' to 'int' 
loses precision
make[2]: *** [CMakeFiles/qyoto.dir/src/qyoto.o] Error 1
make[1]: *** [CMakeFiles/qyoto.dir/all] Error 2
make: *** [all] Error 2

To solve the above problem, I changed the two instances of "return (int)" 
to "return (long)" in the QyotoHash() function.  However, I haven't examined 
whether this change is correct, as I have next to no C++ experience.

Also, in Debian the Smoke library is named "smokeqt4", so I had to change 
CMakeLists.txt in the Qyoto root folder accordingly.

On to the next problem.

I ran make again, a got the following error:

[  4%] Built target qyoto
[  4%] Building qt-dotnet.dll
/bin/sh: debug: command not found
[  6%] Built target qt-dotnet

A snippet from the offending file ( CMakeFiles/qt.dotnet.dir/build.make ):

CMakeFiles/qt-dotnet:
        $(CMAKE_COMMAND) -E 
cmake_progress_report /home/kaare/source/qyoto/CMakeFiles $(CMAKE_PROGRESS_1)
        @$(CMAKE_COMMAND) -E 
cmake_echo_color --switch=$(COLOR) --blue --bold "Building qt-dotnet.dll"
        -debug -define:DEBUG -unsafe -warn:0 -out:qt-dotnet.dll -target:library /home/kaare/source/qyoto/src/SmokeInvocation.cs /home/kaare/source/qyoto/src/SmokeMarshallers.cs /home/kaare/source/qyoto/src/Qyoto.cs /home/kaare/source/qyoto/src/QyotoMetaData.cs /home/kaare/source/qyoto/core/*.cs /home/kaare/source/qyoto/gui/*.cs /home/kaare/source/qyoto/network/*.cs /home/kaare/source/qyoto/sql/*.cs /home/kaare/source/qyoto/xml/*.cs /home/kaare/source/qyoto/svg/*.cs /home/kaare/source/qyoto/opengl/*.cs /home/kaare/source/qyoto/qdbus/*.cs

I guess the "-debug[...]" line should have been on the previous line.  A 
smiliar problem occurs when compiling most of the examples, etc.:

[ 40%] Building collidingmice.exe
/bin/sh: -unsafe: command not found
make[2]: *** 
[examples/graphicsview/collidingmice/CMakeFiles/collidingmice.exe] Error 127
make[1]: *** 
[examples/graphicsview/collidingmice/CMakeFiles/collidingmice.exe.dir/all] 
Error 2
make: *** [all] Error 2

From the offending file ( 
examples/graphicsview/colldingmice/CMakeFiles/collidingmice.exe.dir/build.make ):

examples/graphicsview/collidingmice/CMakeFiles/collidingmice.exe:
        $(CMAKE_COMMAND) -E 
cmake_progress_report /home/kaare/source/qyoto/CMakeFiles $(CMAKE_PROGRESS_1)
        @$(CMAKE_COMMAND) -E 
cmake_echo_color --switch=$(COLOR) --blue --bold "Building collidingmice.exe"
        cd /home/kaare/source/qyoto/examples/graphicsview/collidingmice 
&& -unsafe -warn:0 -out:collidingmice.exe -r:../../../qt-dotnet.dll /home/kaare/source/qyoto/examples/graphicsview/collidingmice/main.cs /home/kaare/source/qyoto/examples/graphicsview/collidingmice/mouse.cs /home/kaare/source/qyoto/examples/graphicsview/collidingmice/qrc_mouse.cs

Notice the line beginning with "cd /home/kaare/source/qyoto[...]"; this seems 
to be a mix of a cd command and arguments for gmcs.

Apparently, CMake version 2.4-patch 5 in Debian unstable created the files 
incorrectly or is working differently from the version of CMake you're using.

When "collecting" the assumed improperly split lines and removing the "cd 
<path> &&" bit from the build.make files, the build finishes successfully, 
but only creating libqyoto.so, not the qt-dotnet.dll.  My fixes to the 
build.make files may be inadequate; I really have no idea what the files are 
supposed to look like when having been generated properly.

If you can point me to a better place to post about these problems, or if you 
need my assistance in testing any changes, please let me know.
