Boy, I should have just tried the development code from the start! However, I
tried it out this morning and I do encounter a problem when running
makeall. It boils down to this:
TCLocalStrings.cpp: In member function 'void TCLocalStrings::mbstowstring(std::wstring&, const char*, int)':
TCLocalStrings.cpp:1180: error: invalid cast from type 'QChar' to type 'wchar_t'
lipo: can't figure out the architecture type of: /var/tmp//cc960xuw.out

Looks like a string conversion issue, but I’m not sure if the architecture
reference implies something else. I’m not familiar with the QT APIs or many
C++ classes, so I haven’t really tried to figure it out.
|
I have to wonder what QChar is defined as in QT4. In QT3, it’s just an integer
type, as far as I can tell. The wchar_t type is just an integer type (4-byte
integer in Linux, 2-byte integer in Windows, not sure about OSX). I suspect
this error will go away if you compile against QT 3.3.7. However, at some point
LDView will be compiled under QT 4, so I’ll investigate to see if I can figure
out what’s up.
| |
Yes, I built my version with QT 4.2.2, which was simply the current version
being distributed by Trolltech. What problems, specifically, should I be looking for with QT 4?
I’ve found ftp//ftp.trolltech.com/qt/source/qt-mac-free-3.3.7.tar.gz, but
unlike QT 4, it’s not building successfully on the first try. Nevertheless,
could the casting error noted above be related to which version of QT I’m
using? At any rate, the border does look nicer - more compact - in the
screenshot you posted.
|
Take a look at todo.txt in the QT source directory of the cvs source. It lists
the QT 4 problems. As for the border, while the QT 4 border looks more
Mac-like, I definitely think the more compact border is more appropriate. Once
LDView itself is targeted more directly at QT 4, that will be one of the things
that get investigated.
| |
Anyway, as for my LDView 3.1 first impressions:
- Cutaway mode is cool.
- POV-Ray camera info export is going to be really handy.
- Automatic download of missing parts is also cool and very handy. I tested it with the example 8464.mpd model, and I was particularly pleased to find that Bricksmith can access the Unofficial parts too.
|
I’m glad that Bricksmith can make use of them. Does it have a UI to add new
directories to the part search path?
| |
- The variety of display options are fun.
- Snapshots are nice.
On the down side,
- The clunkier border and toolbar area you noticed with my QT version remain visible in full screen mode. (The strip between the toolbar and display is really part of the display border, as it remains visible when the toolbar is hidden.)
|
Full-screen mode in general isn’t optimal on the Mac (after all the menu bar
across the top of the screen and the Dock both stay visible as well). That’s
something that will be investigated, but I’m not sure if anything will be done
for true full-screen support. (There’s hope that I’ll eventually have a
Cocoa-native version of LDView. That one would have better full-screen support,
but it’s a long ways off.)
| |
- I can’t seem to invoke “Fly Through” mode - the menu item becomes checked appropriately, but the status bar continues to read “Examine” and none of the fly through controls seem to be active. (In other words, except for the menu indicator, it remains in “Examine” mode.)
|
That’s very odd. It works fine in the version I compiled.
| |
- Very minor - modifier key/mouse controls noted in help text are somewhat different on Mac OS X. Command instead of control, etc.
|
I plan to update the help file to state that anywhere you see the word Control
used, it actually means Command on the Mac. Additionally, Ctrl+click equals
right mouse button (as is standard on the Mac). If you see any other
differences in the modifers, let me know.
| |
It’s exciting to have a new tool in the Mac LDraw arsenal. Please let me know
of any way I can help bring 3.2 to fruition, from testing to simply sharing
more specific information about the problems I’ve noted. Also, given the
presumed Boost/QT dependency of the version I’ve built, and the fact that you
are incorporating more Mac OS X support in the next official release, I’m
thinking it might not be worthwhile to post the version I compiled (as users
will still have to install Boost/QT - something I hadn’t thought of last
night). What do you think?
|
That’s a tough call. On the one hand, only power users are likely to go to the
hassle necessary to get the QT and Boost shared libraries installed onto their
computers. On the other hand, as I mentioned, I don’t currently have an
estimated release date for LDView 3.2. Also, you should have static libs for
Boost already. If you just delete the shared ones and rebuild LDView, it should
remove that particular dependency. If you want, you can try building QT 3.3.
Here are my build command lines:
echo yes./configure -release -static -thread -fast -no-largefile
make symlinks src-qmake src-moc sub-src sub-tools
Before you build it, you have to edit mkspecs/macx-g++/qmake.conf, and update
the QMAKECFLAGS line to look like so:
QMAKECFLAGS = -pipe -arch i386 -arch ppc -isysroot
/Developer/SDKs/MacOSX10.4u.sdk -DQTQLOCALEUSESFCVT
(Specifically, add the -DQTQLOCALEUSESFCVT to the end of the existing line.)
