Posted 05-29-2012 at 10:31 AM by rainbowsally
Updated 06-01-2012 at 01:12 PM by rainbowsally (correction in error msg)

CHANGELOG: 6/1/2001
Corrected argv[<value>] in error msg at line 102 of file: src/qt4-info.cpp.

[If you work with qt4, this is well worth the exercise. You might be surprised at how much we do with so little code. -rs]

Care for a bit of Ye Olde Computer Mad Science? This one is kind of fun.

Todays Features:
  • Look up all QT4 classes and list properties or meta object method calls.

If you have mc2, 'mc2 -fetch qt4' for the Makefile, otherwise, do whatever you do to get this rolling.

Here are the files for this demo/test.

// generic C++ source template created by new.main

qt type id test/demo

Posted 05-27-2012 at 10:38 PM by rainbowsally
Updated 05-27-2012 at 10:40 PM by rainbowsally

Today's features:
  • Use C++ typeid's to compare or check types.
  • Share base64 encoded compressed file/dir data in message forums (example).

The typeid(obj) doesn't require QT, but it also works with it. Here's a simple makefile and a widget to show some type ids and how to compare
them.

After running this you should have a folder named typeid-test. Type 'make' inside that folder to create the 'main' executable.

Requires base64, QT4, make, gcc, and all that...

libLQ-qt-mc2 with qt4 support

Posted 05-27-2012 at 10:22 PM by rainbowsally
Updated 08-06-2014 at 08:06 AM by rainbowsally (new version)

[See note at the bottom IF you have a problem such as:
Code:
  libLQ-qt.so: undefined reference to `obj_copy_op(char**, char*, char*)'
  libLQ-qt.so: undefined reference to `obj_delete_op(char*, char*)'
which you probably won't.
]

This is libLQ with qt support and mc2 (the makefile creator, second generation).

Precompiled cint dlls for linux (ix86) here

Posted 05-26-2012 at 04:49 AM by rainbowsally
Updated 08-06-2014 at 11:09 AM by rainbowsally (arch note)
Tags cint, compiling

These go into
Code:
/usr/local/share/cint/cint/include
by default.

If you have relocated your cint installation, I'm not sure they'll work.

Also I haven't gotten the gl stuff working yet, but if you've had trouble getting these to compile, here's what we have.

They are named '*.dll' but they are linux ELF binaries, and they go into the include folder with the header files so that cint can find them.
