SAS/C options to gcc & Ralph Bablel's WBPath
How do i translate rhe instuctions in SCOPTIONS file to gcc commandline? PARAMETERS=REGISTERS NOSTACKCHECK STRINGMERGE NOMULTIPLEINCLUDES OPTIMIZE LIBRARY=wbpath.o LINK SMALLCODE SMALLDATA STARTUP=cres NOSTANDARDIO The file to compile is gui.c which has an include for "wbpath.h" wbpath.h & wbpath.o are both in the same drawer as gui.c gui.c does use findpath.c function which i did find in a TEXLive AROS archive on Aminet. wbpath is on Aminet and in developer CD V2.1 I managed to do this 3.Datas:Gui4Cli/Dev/Gui/GUI_SRC> gcc -c findpath.c 3.Datas:Gui4Cli/Dev/Gui/GUI_SRC> gcc -c gui.c 3.Datas:Gui4Cli/Dev/Gui/GUI_SRC> gcc gui.o findpath.o wbpath.o -o gui_OS4 wbpath.o: file not recognized: File format not recognized I guess that's because wbpath.o was compiled for 68k Dis somebody get hold of wbpath.c or does somebody know af a replacement for wbpatn ?

Yes the file format is
Yes the file format is different but more to do with GCC being ported from *n*x OS There are some other options that change as well

Here is a C translation I
Here is a C translation I once made from a disassembly of the wbpath.o module: 
  1. #define __NOLIBBASE__
  2. #define __USE_SYSBASE
  3. #include <proto/exec.h>
  4. #include <proto/dos.h>
  5. #include <workbench/startup.h>
  6.  
  7. struct PathNode {
  8. 	BPTR pn_Next;
  9. 	BPTR pn_Lock;
  10. 	};
  11.  
  12. BPTR cloneWorkbenchPath (struct Library *SysBase, struct Library *DOSBase, struct WBStartup *sm)
  13.  
  14. {
  15. BPTR newpath = (BPTR)0;
  16. struct MsgPort *port;
  17. struct Process *pr;
  18.  
  19. Forbid();
  20.  
  21. if (port = sm->sm_Message.mn_ReplyPort)
  22. if ((port->mp_Flags & PF_ACTION) == PA_SIGNAL)
  23. if ((pr = (struct Process *)port->mp_SigTask)->pr_Task.tc_Node.ln_Type == NT_PROCESS)
  24. 	{
  25. 	struct CommandLineInterface *cli = BADDR(pr->pr_CLI);
  26. 	BPTR pathnode = cli->cli_CommandDir;
  27. 	BPTR *last = &newpath;
  28.  
  29. 	while (pathnode)
  30. 		{
  31. 		BPTR checkpn = cli->cli_CommandDir;
  32.  
  33. 		while (checkpn)
  34. 			{
  35. 			if (checkpn == pathnode)
  36. 				break;
  37.  
  38. 			checkpn = ((struct PathNode *)BADDR(checkpn))->pn_Next;
  39. 			}
  40.  
  41. 		if (checkpn)
  42. 			{
  43. 			struct PathNode *pn = BADDR(pathnode);
  44. 			BPTR lock;
  45. 			ULONG *mem;
  46.  
  47. 			pathnode = pn->pn_Next;
  48.  
  49. 			if (!(lock = DupLock (pn->pn_Lock)))
  50. 				break;
  51.  
  52. 			if (mem = AllocMem (sizeof(ULONG)+sizeof(struct PathNode),MEMF_PUBLIC))
  53. 				{
  54. 				*mem = sizeof(ULONG)+sizeof(struct PathNode);
  55. 				pn = (struct PathNode *)(mem + 1);
  56. 				pn->pn_Next = NULL;
  57. 				pn->pn_Lock = lock;
  58. 				*last = MKBADDR(pn);
  59. 				last = &pn->pn_Next;
  60. 				}
  61. 			else
  62. 				{
  63. 				UnLock (lock);
  64. 				break;
  65. 				}
  66. 			}
  67. 		}
  68. 	}
  69.  
  70. Permit();
  71.  
  72. return (newpath);
  73. }
  74.  
  75. void freeWorkbenchPath (struct Library *SysBase, struct Library *DOSBase, BPTR PathNode)
  76.  
  77. {
  78. while (PathNode)
  79. 	{
  80. 	struct PathNode *pn = BADDR(PathNode);
  81. 	ULONG *mem = ((ULONG *)pn)-1;
  82. 	PathNode = pn->pn_Next;
  83. 	UnLock (pn->pn_Lock);
  84. 	FreeMem (mem,*mem);
  85. 	}
  86. }
Don't know if it compiles with GCC, though. It does with Dice C and VBCC.

@Thomas Many thanks Only
@Thomas Many thanks Only struct PathNode is redefined, Compiles perfectly
