Hello,
I have installed CCS4.1.2 and imported the old CCS3.3 project.
Seems to compile OK but linker fails because it cannot find any files mentioned specifically in the linker script file (eg lines 100,101 etc) although these files do exist in the same directory as all the other files it does seem to find (ie does not complain about).
Below is the linker file. I tried removing the ‘debug\’ prefix as shown on line 113 for 'NiosCmds.obj' file in the hope that the linker would add the appropriate path for where the obj files are located. This made no difference.
I guess the linker called by Eclipse is in a different ‘current directory’ compared to being called by CCS3
Hope you can help,
John
