GLScene Installation

[Felipe Alvares de Azevedo Macedo]

Hello friends, I've been using GLScene for a while on RAD Studio, however because of the high cost, and I'm moving to Lazarus!

I've tried to find tutorials to install GLScene on Lazarus 1.8.4 but I couldn't find any! the only version I found was the 1.6 using the GLS 1.4.

Is there a way to install it on newer Lazarus versions? and how?

Hi Felipe!
In the Installation folder there is a file called Installation_lazarus_en.htm.
It works well in Lazarus 1.8 with the latest GLScene aswell.

Cheers!

Hello Daniel! thanks for your reply!

I couldn't find this file... in which version of GLScene I can find it?

Thanks,
Felipe

Hi Felipe!
I assume it's in all the versions.
Here is the repo link: https://sourceforge.net/p/glscene/code/HEAD/tree/branches/GLSceneLCL/installation/

Hi Felipe if you don't want to use Lazarus you can now also download the Delphi Community Edition https://www.embarcadero.com/products/delphi/starter

Hi,
I have problem to install GLScene ver 1.4 to new Lazarus version 2.0.
I change Lazarus version from 1.8.4 to 2.0.

Any help, how can i resolve this problem?

Thank you,

Hi Tambok, i've just tried to install GLScene on Lazarus 2.0 and i haven't got any problem.
Make sure to take source from SVN and place it under the Lazarus/Component/GLSceneLCL folder. If the source of GLScene it's the same as Lazarus 1.8.4 please clean folders of any ppu and others before

Are you on Windows or Linux ?

Hi Jerome,
I use Windows 10 64Bit.
Do you mean the remaining files when lazarus is uninstaled? I have cleaned that.
Yes, i did it, i tried as instructed by https://sourceforge.net/p/glscene/wiki/Lazarus%20Installation/

Are you using GLScene version 1.4 too? because i get several error messages like:

Identifier not found"ParamStrUTF8", in line 656, 29, path := ExtractFilePath(ParamStrUTF8(0));
or
Conversion between ordinals and pointers is not portable, in line 845, 32.

could you explain your intructions/steps, that can i follow it? i tried and failed it again.

thank you

I am back again,
i have tried to go back to the previous version 1.8.4, the problems are same.
Posibility, you are right, there arent problems with the two versions.
Maybe, because of Windows Updates. I already remember there are no changes that i used before in OS except just updating and only uses antivirus and firewall from Windows.

the OS is now Win 10 x64, ver 1803, build 17134.590.
Is there a same problem, maybe something similar?

thank you

Hi perhaps some units are in conflicts between your two version of Lazarus or something was changed in commons paths.

For news, i prepare a new update of GLScene for Lazarus. Coming soon.....

Cheers
