[cells-devel] PortaGLUT: FTGLFromC.cpp: Cannot load C++ object file into ACL6.2
by Frank Goenninger 23 Feb '04

23 Feb '04

Hi all: I tried to create a shared lib from the file FTGLFromC.cpp and succeeded in doing so. But when trying to load the new libftglint.so (for "FTGL Interface") I see the following error in ACL62Trial on Linux: ; Loading /home/frgo/projects/cello/ftgl-int/libftglint.so.1 Error: Attempt to take the value of the unbound variable ^?ELF^A^A^A ... [condition type: UNBOUND-VARIABLE] So I decided to check if the lib is valid in its format. I put togehter a simple main.cpp file: --X-- #include <stdio.h> #include <dlfcn.h> #include "FTGLTextureFont.h" #include "FTTextureGlyph.h" #define LIBFTGLINT "/home/frgo/projects/cello/ftgl-int/libftglint.so.1" #define FONT "Verdana" extern "C" { int main( int argc, char **ppcArgv ) { int nRC = 0; void *pvHandle = NULL; char *pcError = NULL; /* FTGLTextureFont *psTextureFont = NULL; */ void *psTextureFont = NULL; typedef void* (*fgcTextureMakeSymPtr)(const char *); fgcTextureMakeSymPtr fgcTextureMakeFRGO = NULL; void *fgcTextureMake = NULL; pvHandle = dlopen( LIBFTGLINT, RTLD_LAZY ); if( pvHandle == NULL ) { fprintf(stderr, "%s !\n", dlerror()); nRC = 1; } if( nRC == 0 ) { fgcTextureMake = dlsym( pvHandle, "fgcTextureMake" ); if(( pcError = dlerror()) != NULL ) { fprintf( stderr, "%s !\n", pcError ); nRC = 1; } if( nRC == 0 ) { fgcTextureMakeFRGO = (fgcTextureMakeSymPtr) fgcTextureMake; psTextureFont = (*fgcTextureMakeFRGO)( FONT ); printf("psTextureFont = %x\n", psTextureFont ); } dlclose( pvHandle ); } return nRC; } } /* extern "C" */ --X-- and when running the resulting little program I actually get a valid address for the texture font pointer. This clearly shows that building the shared lib succeeded. In ACL62Trial I get this error whenever I try to load a shared lib that has some C++ object files in it. I double checked on the right compile options and flags... Any ideas? I couldn't find anything on Franz's WWW pages and also googling didn't reveal something. Thx for feedback! Regards, Frank

[cells-devel] PortaGLUT
by Kenny Tilton 23 Feb '04

23 Feb '04

After reflecting on Raistlin's input, and my previously expressed interest in breaking Cello up into discrete components, I suddenly recalled that the nehe-14.lisp demo did not even require Cells. It was a pure test of Lisp+UFFI+Freeglut+OpenGL. That alone would be useful to many, so I think I will tackle that when I get back from the gym. I will test it under ACL62 and ACL501, as well as whatever LW and Trial versions will run it, then make it available by FTP. Sorry for spamming the Cells list with this, but we still do not have a second working platform, so Cello does not yet exist. By the end of the week this will be resolved. Hell, if we get PortaGlut working on other platforms I will apply for a new project on common-lisp.net. kt -- http://tilton-technology.com Why Lisp? http://alu.cliki.net/RtL%20Highlight%20Film Your Project Here! http://alu.cliki.net/Industry%20Application

Current one is attached, but it just builds UFFI the way ASDF would. I am perty sure I still have acl501 on my old NT box.

Ah, yes, vague memory on that. Thx for the reminder. btw, did you grab the latest UFFI?

I forgot that was pulled in my the bindings project when I was downsizing the zip to get it thru. Anyway, looks like it needs work, it exits and takes down ACL just after opening the window. You guessed right, it is a throwaway, but maybe I should bring it back since it is a nice half-port: it only requires freeglut (or some glut). Anyway, the first thing I will do is get all this sorted out /and/ put the next zip up on tilton-technology with a password (unless I can figure out SSH again and just FTP it up to the common-lisp project. but then I also have to figure out the GnuPG thing because they want me to sign this stuff. :() > > > ---Errors Part5--- > ; While compiling CELLS-TIME-REPORT in c:\Cello-Dev\cells\debug.lisp: > Warning: EXCL::TIME-REPORT should be given exactly 9 arguments.

I think I'll just put it up on my web site, because most people have had trouble getting it via email. Plz confirm you did not receive and I will do that. As for making a wish, that is very generous of you. It would be fine if you just played the part of user (vs. porter) and helped me figure out what documentation or examples to write. (I always prefer examples, and those are easier for me to pull together.) If you are really interested in porting, then Corman is the one implementation remaining to cover. CLisp (I think!) does not handle callbacks from C, which we need to use Freeglut. Hey, who else is working on Corman? So many have asked for distros, I have lost track. :) kenny -- http://tilton-technology.com Why Lisp? http://alu.cliki.net/RtL%20Highlight%20Film Your Project Here! http://alu.cliki.net/Industry%20Application

If you activate them all expect a healthy delay when the window opens since all the structure gets built before you see the window the first time. Expect a memory leak forcing you to quit ACL if you play around very long. Then you might want to try playing with the demos to see what changes what. Ideally you have a project in mind we could work on. I like the Black Book approach to documentation, which presumes you have some real world task to do and shows how to get it done all in a few pages, no matter how many different activities are involved. But step one is to achieve the null port.

[cells-devel] help wanted
by Kenny Tilton 23 Feb '04

23 Feb '04

Speaking of "where is help needed", depending on one's skill set, here are some that I have been deferring: These two would be good for a strong C and esp. win32 programmer: -- Freeglut/win32: calling glutMainLoop leaves the app taking 100% of CPU. This is weird because win32 apps are supposed to wait until their windowproc gets called. Possibly they are failing to handle repaint events (in which case I think you just keep getting called again and again) or they are doing something to cause windows to send the app events non-stop, such as by invalidating the window after handling each paint event to cause another to be sent straight away. -- Freeglut/win32: before the current release I had code which called glutMainLoopEvent to handle one event at a time. When I resumed work on Cello under the latest FG I found that broken in some way such the I simply did not receive all the events I should. And if anyone is strong on OpenGL: -- Drawing seems mighty fast, and I have a feeling most of the bottleneck is not in the drawing in which case we shouldn't spend too much time on this, but I am sure we could get even better performance via standard OpenGL tuning techniques such as display lists. kenny -- http://tilton-technology.com Why Lisp? http://alu.cliki.net/RtL%20Highlight%20Film Your Project Here! http://alu.cliki.net/Industry%20Application

[cells-devel] FTGL dll issue
by Kenny Tilton 22 Feb '04

22 Feb '04

Thought I should mention this. I have noticed a pattern: perhaps only because of the Freeglut/win32 problem in which it pegs the cpu at 100% forcing heroic measures to stop it, often after landing in a backtrace and fixing a bug and running again I end up with an access violation on a simple call into the FTGL. Then I have to exit Lisp and come back in. Not good, obviously, and something to be addressed before not too much longer, but for now if you suddenly see something like that you might want to try bouncing the Lisp. kenny -- http://tilton-technology.com Why Lisp? http://alu.cliki.net/RtL%20Highlight%20Film Your Project Here! http://alu.cliki.net/Industry%20Application

[cells-devel] uffi + steppin out...
by Kenny Tilton 21 Feb '04

21 Feb '04

To those who receive 'lite' distros, I also had to whack the uffi and asdf libs. cello runs against untouched copies of those, so you can just grab them from their sites. i promise we'll cut to an ftp arrangement on the next go-round, even if on my own web site. stepping out at 5:30 nyc-time for the evening. thx for all the interest. if anyone thinks they are making progress lemme know and I will stop worrying about porting and start on the missing widgets (and see why freeglut uses 100% cpu on win32). kenny -- http://tilton-technology.com Why Lisp? http://alu.cliki.net/RtL%20Highlight%20Film Your Project Here! http://alu.cliki.net/Industry%20Application

[cells-devel] FTGL "C" glue: FTGLFromC.cpp, fgc.def
by Kenny Tilton 21 Feb '04

21 Feb '04

Short and sweet. Just enough C to let Cello at the FTGL C++ libs. These files are for those not on win32. I just added this source to the FTGL win32 VC++ project. The author of FTGL has expressed an interest in this code, so maybe he will add a C interface soon and we can stop forking. An alternative I guess would be for me to make my own FTGL-C dll and link that against an unmodified FTGL static lib. I took the quick way out for now. kenny -- http://tilton-technology.com Why Lisp? http://alu.cliki.net/RtL%20Highlight%20Film Your Project Here! http://alu.cliki.net/Industry%20Application #include <assert.h> #include "FTGLBitmapFont.h" #include "FTBitmapGlyph.h" #include "FTGLPixmapFont.h" #include "FTPixmapGlyph.h" #include "FTGLTextureFont.h" #include "FTTextureGlyph.h" #include "FTGlyphContainer.h" #include "FTBBox.h" #include "FTGLPolygonFont.h" #include "FTPolyGlyph.h" #include "FTGLOutlineFont.h" #include "FTOutlineGlyph.h" #include "FTGLExtrdFont.h" #include "FTExtrdGlyph.h" extern "C" { bool __stdcall fgcSetFaceSize( FTFont* f , unsigned int faceSize , unsigned int res ) { return f->FaceSize( faceSize, res ); } float __stdcall fgcAscender( FTFont* f ) { return f->Ascender( ); } float __stdcall fgcDescender( FTFont* f ) { return f->Descender( ); } float __stdcall fgcStringAdvance( FTFont* f, const char* string ) { return f->Advance( string ); } float __stdcall fgcStringX( FTFont* f, const char* string ) { float llx,lly,llz,urx,ury,urz; f->BBox( string, llx, lly, llz, urx, ury, urz ); return llx; } void __stdcall fgcRender( FTFont* f, const char *string ) { f->Render( string ); } void __stdcall fgcFree( FTFont* f ) { delete f; } //--------- Bitmap ---------------------------------------------- FTGLBitmapFont* __stdcall fgcBitmapMake( const char* fontname ) { return new FTGLBitmapFont( fontname ); } //--------- Pixmap ---------------------------------------------- FTGLPixmapFont* __stdcall fgcPixmapMake( const char* fontname ) { return new FTGLPixmapFont( fontname ); } //--------- Texture ---------------------------------------------- FTGLTextureFont* __stdcall fgcTextureMake( const char* fontname ) { return new FTGLTextureFont( fontname ); } //--------- Polygon ---------------------------------------------- FTGLPolygonFont* __stdcall fgcPolygonMake( const char* fontname ) { return new FTGLPolygonFont( fontname ); } //--------- Outline ---------------------------------------------- FTGLOutlineFont* __stdcall fgcOutlineMake( const char* fontname ) { return new FTGLOutlineFont( fontname ); } //--------- Extruded Polygon ------------------------------------- FTGLExtrdFont* __stdcall fgcExtrudedMake( const char* fontname ) { return new FTGLExtrdFont( fontname ); } // make a new extrd ctor that takes a depth parm bool FTGLExtrdFont::FaceDepth( float new_depth ) { Depth( new_depth ); return FaceSize( this->FaceSize(), 96 ); // force new glyphs } bool __stdcall fgcSetFaceDepth( FTGLExtrdFont* f , float depth ) { return f->FaceDepth( depth ); } } DESCRIPTION 'C Interface to FTGL' VERSION 0.1 EXPORTS fgcSetFaceSize fgcStringX fgcAscender fgcDescender fgcStringAdvance fgcRender fgcFree fgcBitmapMake fgcPixmapMake fgcTextureMake fgcPolygonMake fgcOutlineMake fgcExtrudedMake fgcSetFaceDepth
