Replacing TMetafile with TBitmap and TMetafileCanvas with TBitmapCanvas with some little change they can works under Linux and other OS to. What TMetafile do you mean? There is none in the LCL. Yes I know, for instance there is the Luís Rodrigues TMetafile (mymetafilepkg.lpk) in the CCR that wrap the Windows EnhMetafile API (so Windows specific) and some extra lazarus packages like PagePrinter uses Metafiles. Replacing Metafile with Bitmap can remove this MS Windows API dependences. To do this, TBitmapCanvas, should be visible in PagePrinter units by mean Graphics unit.

The aforementioned machine runs windows xp, yet in other windows xp and windows 2000 versions I've tried, the program worked fine, also under wine. The project compiled for linux and mac behaved correctly. The program only performs various calculations according to a given input specified by the gui and plots several charts. No input files, no output files and no environment variables are used. I would appreciate any ideas of why something like this could possibly occur. First thing that comes to mind is different locale setting, i.e. decimal separator etc. E.g. assuming the gui inputs are some floating point values entered in edit fields and later converted to float with StrToFloat, the conversion will fail, if the edit contains 1.23 but the systems decimal separator is set to , (like e.g. on a german system) and thus expects 1,23. In that case can help to set DecimalSeparator:=','; ThousandSeparator:='.'; or viceversa at main form create event Regards Salvatore regards Burkhard ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
