John what is strange is that when I use the sophie-dev image it works, so I thought that it was something at the image level but this is the same code that I filled in. Stef

Re: [Pharo-project] Linux graphics for Windows programmers??

by Schwab,Wilhelm K

Bert, Thanks! The other lingering topic is how to create an image/Form in Smalltalk and draw on it in a C-callable function in a .so. I am thinking of loops over large data sets. It is easy to make the library and call its functions, but I am not sure about passing the form into it. Is there a way to do that with FFI, or is a plugin the only option? Am I perhaps crossing into OpenGL territory? For good or bad, I have never passed a Windows printer HDC into C code, but one could do so.

No need to pipe to gs manually. The spooler uses CUPS which invokes GS (unless printing to a PostScript printer). And yes, you can do this from the terminal.

Ok, well I'm less distracted and tense this afternoon. So I'm just attempting to compile up everything on an old powerpc test machine that I used to build the rome plugin. Unfortunately the current source code won't compile on my current work machine because it requires installing rome, and 55 other unixy things in order to do the compile, build, debug cycle. However I hope to get to the point of being able to determine exactly *why* the primitive fails. -- =========================================================================== John M.
