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
