Using the makefile the following error is encountered C:DevFreeRTOSDemoCygnal>make MAKE Version 5.2  Copyright (c) 1987, 2000 Borland Fatal: ‘..\..Sourcetasks.rel’ does not exist – don’t know how to make it snapshot SDCC NOV/2004 was used and the project files and directories were installed in C:DevFreeRTOS Thanks for your support athari9@telus.net

Hi, Using Borland’s make does not seem to work.  I just tried it and got exactly the same error.  Using the UNX Utils version works fine.  See: http://unxutils.sourceforge.net/ Make sure the UNX Utils version of make appears in your PATH before the Borland version. Regards.

Thanks for the quick reponse. I tried GNU MAKE 3.75 and UNX MAKE for windows and this is the error I get in both cases 11/20/2004  02:42 PM    <DIR>          . 11/20/2004  02:42 PM    <DIR>          .. 11/20/2004  02:27 PM            37,317 8051rtos.wsp 05/04/2004  08:19 AM            27,090 c8051f120.h 11/20/2004  01:59 PM            16,594 main.c 11/21/2004  12:15 AM             3,065 Makefile 11/17/2004  02:17 PM    <DIR>          ParTest 11/20/2004  02:30 PM            36,898 sdcc.wsp 11/20/2004  02:01 PM    <DIR>          serial                5 File(s)        120,964 bytes                4 Dir(s)  23,118,036,992 bytes free C:DevFreeRTOSDemoCygnal>make make: *** No targets specified and no makefile found.  Stop.

That is very odd.  If you type "make –v" what do you get.  My output is as: GNU Make 3.80 Copyright (C) 2002  Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. If you are using the same version I cannot see any reason why it would think the makefile was not there. Some thoughts: Could it be that it does not like the capital ‘M’ in Makefile.  Try making it a lower case ‘m’. Try specifiying the file to make, as in "make –makefile=Makefile" – maybe even with the path also. Which host operating system are you using?  I am using Win2k.

Hmm.  Still strange.  It seems to be taking Sourcetasks.c as a single file, rather than SourceTasks.c.  XP should not care which way round the slashes go. I will not be able to test on an XP machine until tomorrow unfortunately as I don’t have one available here. What happens if you run the command line manually rather than through make?  -——– sdcc -c –model-large -I. -I..Commoninclude -I..include -I..\..Sourceinclud e -DSDCC_CYGNAL –debug –less-pedantic –xram-size 8448 –stack-auto –no-peep --int-long-reent –float-reent ..\..Sourcetasks.c -——– If this builds the single file ok then the finger still points at make.  If this has the same problem then make is probably ok now.  If this works then maybe you could convert the makefile into a batch file until I have a change to try it under XP. Regards, Richard.

Hi Richard, Calling the compiler directly seems to work. Tasks.c was built with no difficulty. Thanks for your help and I’ll wait for your update. Cheers Adam

I just tried: - putting unx tools, the latest FreeRTOS release, and SDCC onto a clean (i.e. never installed before) XP machine. - Opening up a command prompt and from there adding the unx tools and sdcc paths to the PATH environment variable as the first two paths in the list. - Navigating to the Cygnal directory and typing ‘make’. The demo built with no errors or warnings. This is a puzzle but seems to be something related only to your machine.  Could you try the 3.80 version of make? Regards.

i am having iar c cross compiler  can i use

Each port requires a particular device and a particular compiler.  As each compiler uses memory in a different way and generates different code sequences it is unlikely that you would be able to use the IAR compiler without some porting effort.
