Hi Don,

If you'd like to make some progress, try these steps.

Stop doing anything with cygwin.

Go to the sdcc site on sourceforge and download the windows installer for sdcc:
http://sourceforge.net/projects/sdcc/?source=directory

Just click on the green button that says 'Download'.

Save the sdcc installer file to your local drive and run the installer, accept the defaults.

Make sure you make a note of what folder sdcc was installed into, such as c:\programs\sdcc or c:\programs (x86)\sdcc.

Open Silabs IDE and click on Project, Tool Chain Integration, then near the top, select the drop box arrow next to Preset Name.  Select preset name sdcc 3.x read only and press enter.  Click on each of the three tabs, assembler, compiler, and linker, and verify the path and program names are correct. 

Next, start a new project, and add a new file.  Select the radio button for 'C Source File', and click OK.  In the new file type something simple like:

void main(void)
{

}

and save the file.  

At this point, you should be able to compile the program for sdcc from within Silabs. Click on Project, Build/Make, to start compiling.

I just did the above steps and the program compiled and linked successfully.

Good luck!

Rich.

Hello Don,
 
I have no experience with CYGWIN so can't help you there. Why do'nt you run SDCC in Silabs IDE under Windows 7 ?
 
regards

HI Guys
Thank you for your input. I think part of the problem is that I am trying to run the Silab IDE and the SDCC compiler on a Windows 7 machine and I have no idea how to use cygwin. I have installed cygwin and can open the little black window with the command prompt. After that I have no idea what to do? I know nothing about linix. I do not understand how you can run a Linix program  like SDCC inside a windows 7 programs like Silab IDE?
 
The contents of the file cyglink.txt file is the following:
 
"C:\Users\Don\Documents\iTech\DTMF Project\DTMF SDCC Code\generator\dtmfgen.obj"  TO( "C:\Users\Don\Documents\iTech\DTMF Project\DTMF SDCC Code\generator\DTMF Generator SDCC" ) RS(256) PL(68) PW(78) LIBPATH(C:\Program Files (x86)\SDCC\lib)
This file is created when I run the SDCC compiler in the Silabs IDE.
 
Any more help would be much appreciated. Remember I am a Newbie to compiling. The last time I did microcontroller development work we were using assembler language.
THANX Don Voth

I'm using the sdcc with SILABS IDE for several years now and never encountered a problem with SDCC.

Hi iTronix,

This looks weird -- symbols from the C source / .asm output interpreted as filenames? Might be due to some problems with pipes between preprocessor, compiler, assembler, and linker in cygwin. If I remember correctly, this at one time was indeed a problem -- unfortunately I do not remember the solution (or workaround). You might try searching the mailing list archive or the web for "pipe cygwin" and your Windows version (XP?).

Could you post Windows version, exact command line, command line and output with -V (capital Vee) added? If you pass complete filenames, you might need to quote them ("Program Files (x86)" is otherwise treated as three files ...).
Sorry, I have no clue as to how to do this with Silabs IDE. Could you run sdcc from the command line / cygwin shell directly and report the results?

Link in progress...
C:\Program Files (x86)\SDCC\bin\sdcc.exe @"C:\Users\Don\Documents\iTech\DTMF Project\DTMF SDCC Code\generator\cyglink.txt"
 
at 1: warning 119: don't know what to do with file '@C:\Users\Don\Documents\iTech\DTMF Project\DTMF SDCC Code\generator\cyglink.txt'. file extension unsupported

The leading "@" confuses me. Maybe the above hints help to sort this out as well ... What's the contents of cyglink.txt? Is this file generated by the IDE or hand-written?

Kind regards and Merry Christmas,
Raphael

========================

Hello,

(Note, this question probably should have been directed to the Silabs forums.)

This is the first time I've heard of people using Silicon Labs IDE with sdcc, so I downloaded and installed the Silabs IDE program, in Win XP.  The default toolchain settings calls Ride, using these commands:

DB OE QUIET INTXD OT(6,Speed) PIN(C:\SiLabs\MCU\Inc;C:\RIDE\inc;C:\RIDE\inc\51)

sdcpp doesn't know what to do with these commands, since they are targeted for rc51.

In Silabs IDE, click on Project, Tool Chain Integration, then select the drop box down arrow under Tool Definition Presets, and select SDCC 3.xx.  Then browse to find where SDCC is installed.

Hope this helps!

Rich.
