    Problems installing GlScene :(

    Hi, im having some problems installing glscene for lazarus, and hope someone can help me.
    I downloaded GlScene, and opened the glScene_designtime package for lazarus, and tried to install it, and compiled the IDE. I got these errormessages:
    C:\Data\Pascal\GLScene\Source\Base\VectorGeometry. pas(1257,11) Error: Function is already declared Public/Forward "SinCos(const Double,out Double,out Double);"
    C:\Data\Pascal\GLScene\Source\Base\VectorGeometry. pas(1265,11) Error: Function is already declared Public/Forward "SinCos(const Double,const Double,out Double,out Double);"
    C:\Data\Pascal\GLScene\Source\Base\VectorGeometry. pas(1369,10) Error: Function is already declared Public/Forward "MinFloat(const Double,const Double)ouble;"
    C:\Data\Pascal\GLScene\Source\Base\VectorGeometry. pas(1372,10) Error: Function is already declared Public/Forward "MinFloat(const Double,const Double,const Double)ouble;"
    C:\Data\Pascal\GLScene\Source\Base\VectorGeometry. pas(1381,10) Error: Function is already declared Public/Forward "MaxFloat(const Double,const Double)ouble;"
    C:\Data\Pascal\GLScene\Source\Base\VectorGeometry. pas(1384,10) Error: Function is already declared Public/Forward "MaxFloat(const Double,const Double,const Double)ouble;"
    Could someone please have a look at what im doing wrong / what is wrong? Thanks in advance!

    Hmm... looks like you should put your error messages in a textbox so they don't get all messed up like that.

    Have you found a solution or are you still having trouble with installing GLScene?

    Similar issues with other libraries have taught me that you might not have all the proper paths entered into your includes path for your project. Have a look under Project -> Compiler Options... and give them a look over.

    @WILL:
    No it still doent work. Do you know how i have to configure the paths?

    Is it possible that there is something wrong with the code?

    Hi T-Bear,
    I guess you are using FPC 2.6.0. There is something problematic with that and GLScene. I installed FPC 2.4.4 and the Lazarus version with that (0.9.30.2 I guess) and GLScene was compiled and installed. Also, just today I have found this thread and this may hold the key for a successful FPC 2.6 based installation. I did not try it yet, but it was the errors I encountered if I recall correctly. (Go down on the thread though.)

    Hope this helps.
