ERRORS of compile the Cygnal project: I downloaded the sdcc compiler for windows of 2.8.0 version from sourceforge and installed in full model,then I typed make in the /Demo/Cygnal directory,but some errors came, as below: ?ASlink-Warning-Couldn’t find library ‘mcs51’ ?ASlink-Warning-Couldn’t find library ‘libsdcc’ ?ASlink-Warning-Couldn’t find library ‘libint’ ?ASlink-Warning-Couldn’t find library ‘liblong’ ?ASlink-Warning-Couldn’t find library ‘libfloat’ ParTest/ParTest.rel: cannot open. make: *** [main] Error 1 who can tell me why and how to resolve this ?

I would guess either the PATH variable was not set correctly (environment variable), or the makefile contains paths that are not correct for your machine. Actually, I seem to remember that the Cygnal demo needed some libraries to be downloaded from the FreeRTOS site. Check the documentation page for the port to see if there is a link.

Hello wang xiao I have the same problem…….I just did all that the web side says but , I still have the problem…. how did you solve the problem?…….please thanks daniel

Hi There, I am also having some problems with this demo, however I did get further than this so I’ll try help you out. On the demo page read the text under the heading "Compiler, header file and library versions", there is a file you need to download, unzip and place in sdcc/lib/large. You will then need to add "–lib-path c:/sdcc/lib/large" to the make file. See my post "http://sourceforge.net/forum/forum.php?thread_id=3081738&forum_id=382005" for details. Please post back if you get it all running and working then maybe you can help me? Thanks, Frazer
