mwldmcf.exe linker error for coldfire mcf52211(codewarrior v7.2)

I am getting the following linker error when i try to make a command line build(using makefile) for coldfire mcf52211 using codewarrior v7.2:

C:\\"Program Files"\Freescale\\"CodeWarrior for ColdFire V7.2"\ColdFire_Tools\Command_Line_Tools\mwldmcf.exe

mwldmcf.exe: unable to find EWL lib:

I set the following environment variables but for some reason linker is not able to find the library path:

CWFolder       : 'C:\Program Files\Freescale\CodeWarrior\CodeWarrior for ColdFire V7.2'
CWINSTALL      : 'C:\Program Files\Freescale\CodeWarrior for ColdFire V7.2'
LM_LICENSE_FILE: %CWFolder%\license.dat
MWCIncludes    : %CWFolder%\ColdFire_Support\ewl\EWL_C\Include; %CWFolder%\ColdFire_Support\ewl\EWL_C\Include\sys
MWLibraries    : %CWFolder%\ColdFire_Support\ewl\lib

Any help to resolve this issue?

Hello

Did you try setting MWLibraries to

"C:\Program Files\Freescale\CodeWarrior for ColdFire V7.2\ColdFire_Support\ewl\lib\v2"; "C:\Program Files\Freescale\CodeWarrior for ColdFire V7.2\ColdFire_Support\ewl\lib"

and set MWLibraryFiles to libc.a;librt.a;libm.a;fp_coldfire.a

Additionally for some reason you have some times two backslashes and sometimes just one in the path specification. Not sure how this one is build up, and why this is so...
