thanks for the help-patch.

do you have a screenshot of the expected result (the lower left quad is always empty for me)

hmm, my result differs:

i had to fix a number of things in your code to get the correct glsl program-id (just adding 0.5 is the wrong way to do it), and to prevent crashes. i also moved your example from the help-file into examples/10.glsl/16.vertexbuffer_attributes.pd.

could you please try an updated version of Gem (2c4a280) to see whether i accidentally broke something?

and this is what i get on OSX-10.9

i tried earlier today with the latest gemvertex cpp/h and Gem src but got these errors:

"no need to run autogen.sh again.
though i really wonder how you managed to build before.
were you using the Xcode-project (which is not recommended, before you
start doing that)?"

you mean to get it up and running to begin with? no x-code. just a makefile with paths to gem-0.93.3 src

[jptrkz]

no luck with autogen.sh after gettext install (brew and manually from site with latest version)
still get "configure.ac: not using Gettext"

so the problems we're experiencing are probably rooted in the fact that i modded the files while using 0.93.3?

any other options to make the darwin (gem)?

ok finally got through ftgl/freetype swamp with the aid of this:
#28

edit
** i've compiled the latest Gem commit w/ pd-0.45-4 ** - i run the help patch and shader output is perfect - i can confirm it's the one you've made changes to because of the different output with a "print_attributes" msg

(on a side note - i can't create a 'gemwin' object - i ended up using the 'modular' abstraction version)

Hi,
glGetActiveAttrib at line 594 in gemvertexbuffer.cpp is returning incorrect GLenums for the attributes. I have two machines running the same version(latest) of gemvertexbuffer, Gem, Pd-Vanilla, and the help file. On the 32 bit machine with OSX10.6 the values are correct and the shaders work, but on the 64 bit machine with OSX10.11 they are wrong and there is no visual output. Even if I edit the function to force the vector sizes to be consistent with the .frag/.vert files in this example, I still get no output. The values before line 594 are all consistent so I have no idea how to investigate further.

since this PR has been merged, would you mind opening a new issue for any new bugs popping up (including the last one)?
