Thank you!

I installed Konstruktor beta from openSUSE KDE 4.6 playground. It asked me for the library, so I downloaded the .zip and unzipped it to /home/user/.LDraw/ldraw. I also added the updated parts file. Now Konstruktor crashes at startup after I selected that path. After I click away Dr.Konqui, I get a popup saying "Could not scan LDraw part library."

Here's the backtrace:
Application: Part database updater for Konstruktor (konstruktor_db_updater), signal: Segmentation fault

Hello, I came across this program today while looking for a digital LEGO building app. Editing a LEGO structure is great... except I can't save anything. It crashes every time.

Eh, sorry. I didn't realize I was on comments page 2. Just saw the previous page. Reinstalled kdelibs and that seems to have fixed it.

I have a problem. When I'm run cmake, I see the next message:

CMake Error at /usr/share/cmake/Modules/FindKDE4.cmake:98 (MESSAGE):
ERROR: cmake/modules/FindKDE4Internal.cmake not found in
/home/al_exe/.kde4/share/apps;/usr/share/kde4/apps;/etc/kde4/share/apps
Call Stack (most recent call first):

OS is openSUSE 11.3. The cmake is 2.8.1. Help please, what packages I'm need?

I created a small model and Konstruktor crashed after confirmation of save dialog.

And it is always crashing. So I'm not able to save any model.

Konstruktor looks great, but without save is not usable :-(

Now looking to it. Which distro do you using? This problem seems likely to be caused by shared-mime-info, not the application itself.

mkyral

Thanks.

It is on Gentoo.

Thanks. A couple of days ago I couldn't download it using Opera, but now it worked with Konqueror+WebKit.

mkyral

So I rebuilded all mime related packages and not it works correctly.

Thanks for hint.

Where did you get "ldraw" package for Gentoo?

Hi! Thank you very much for this app!
I've created a PKGBUILD for Arch Linux users:

Builds fine on Fedora 14. Please add an INSTALL file with building instructions.

drkonqui-backtrace here:
http://pastebin.com/CJfJ6RDk
i started konsructor directly from its build-directory with
$ PATH=$PWD:$PATH ./konstruktor

qwertzuiop

fixed the crash by changing
line 27 of renderer/opengl_extension.cpp
from:
if (std::strstr((const char *)str, name) != NULL)
to:
if (str && std::strstr((const char *)str, name) != NULL)

cheers,

i might add that i am using F14 64bit on an intel i7 with an nvidia card using nouveau driver...
maybe this explains that glGetString(GL_EXTENSIONS) returns an empty string

I could not build Konstruktor from sources, log: http://ompldr.org/vNzkxdQ

Which distro and gcc version you use?

qwertzuiop
10 years ago

that's strange, it builds on my machine.
but looking at the header it really seems that there needs to be a forward-definition for ldraw::model for it to compile.
so do the following:
add "namespace ldraw { class model; }" (without quotes)
in line 10 of src/app/submodelwidget.h

this should make it work.
btw, what version of gcc is installed on your system? (gcc -v will tell you)

qwertzuiop

forgot something:
add #include <libldr/math.h>
at line 13 of src/app/editor.h

aspotashev
10 years ago

gcc version: 4.4.5
Distro: Gentoo

Adding the 2 lines (forward definition and an #include) helped, thanks! Now it compiles and runs. But I haven't yet found out how to install the ldraw library on Gentoo.
