<u>Creating new GEM objects</u></h2></center>
|
|
Look at the source code :-) GEM is written in C++, which means that
|
|
you have to jump through some hopes to interact properly with Pd, which
|
|
is written in C. If you look in Base/CPPExtern.h, you will see a
|
|
collection of macros which you can use to help you create new objects.
|
|
Use one of the GEM objects which is closest to what you want to do as a
|
|
template.
|
|
<p>One problem on SGI...you will need to
|
|
<p>setenv LD_LIBRARY_PATH "/where/ever/pd/gem"
|
|
<p>so that rld (the run-time linker) can find the GEM dso. Because
|
|
you are linking with GEM, Pd isn't involved with the run time linking process;
|
|
it is all done when Pd calls dlopen.
|
|
<p>On NT, there is much the same problem...
|
|
<p>set your PATH environment variable to \where\ever\pd\gem
|
|
<p>or
|
|
<p>make sure that your new .dll is located in the same directory where
|
|
GEM is.
|
|
<p>On NT, all of the classes and functions are exported through declexport/declimport.
|
|
You shouldn't have to do anything to call the functions. I have not
|
|
had any problems making other dll's which are loaded into Pd at runtime.
|
|
You need to make certain that you are exporting the correct functions.
|
|
If your dll cannot find the gem.dll, then it will silently fail.
|
|
<p>And of course, e-mail IOhannes m zmölnig (<a href="mailto:zmoelnig@iem.at">zmoelnig@iem.at</a>) if you have any problems,
