Applications by linux-users

[Absum]

Is there anyone out there who has made applications in linux for the space navigator? It would be nice to hear from anyone who atleast have tried

Hi Absum,

have you had a look to our SDK for Unix/Linux? If you want to work with it I can send you some documentation for it.

Thanks some documentation would really be helpfull, I seem to be stuck at the moment trying to initialize the SDK/driver.

Code: Select all

include/xdrvlib.h:68: error: too many arguments to function 'int MagellanInit()'
include/BaseFrameListener.h:145: error: at this point in file

even tho the call is MagellanInit(xd, xw)

[UtaSH]

Please try this:

add the following lines to xdrvlib.h

Code: Select all

#ifdef LINUX
#define ParameterCheck
#endif

or in case you did not #define LINUX only this

Code: Select all

#define ParameterCheck

Code: Select all

g++ -o bin/release/main src/main.o include/xdrvlib.o -L. -lOgreMain -lOIS -lX11
src/main.o: In function `BaseFrameListener::setupSpaceNav(_XDisplay*, unsigned long)':
main.cpp:(.text._ZN17BaseFrameListener13setupSpaceNavEP9_XDisplaym[BaseFrameListener::setupSpaceNav(_XDisplay*, unsigned long)]+0x15): undefined reference to `MagellanInit(_XDisplay*, unsigned long)'

Still get basically the same error as i've gotten the last couple of hours i've tried getting this to work with ogre3d. The function is there and it takes the right parameters but me thinks it looks like its the linking thats the error.

[UtaSH]

The message looks af if xdrvlib.c was not compiled and the linker can't find the xdrvlib.o ??

Are there any other warnings or errors before the linker message?

[Absum]

No thats the only one... im using scons building system and im pretty sure it builds and links in the xdrvlib.o. But i do get the same error when not linking in xdrvlib.o :O

Here is the whole output with -Wall specified.

[UtaSH]

I can not see from the messages when the xdrvlib.c is compiled.
Can you find it in your directory src?

There, i've modified the buildscript so that xdrvlib is compiled as a static library, don't know if that is correct but i get the same error and you can see that it compiles.
I've also created a new thread about this in the linux development forum... thought it would be more appropriate

[UtaSH]

True. This thread makes more sense in the Developer's Forum for UNIX/Linux. See here.
