Hi Pierre!

this is a real head-scratcher since everything looks like it should be working.

here are some of the things you mentioned: 

jar at Win8 /cygdrive/d/Dev/Retro/CoCo/Projects/TestCMOC
$ cmoc -v
cmoc (cmoc 0.1.52)

jar at Win8 /cygdrive/d/Dev/Retro/CoCo/Projects/TestCMOC
$ which cmoc
/usr/local/bin/cmoc

jar at Win8 /cygdrive/d/Dev/Retro/CoCo/Projects/TestCMOC
$ lwasm --version
lwasm from lwtools 4.15

jar at Win8 /cygdrive/d/Dev/Retro/CoCo/Projects/TestCMOC
$ which lwasm
/usr/local/bin/lwasm

jar at Win8 /cygdrive/d/Dev/Retro/CoCo/Projects/TestCMOC

lwlink: error: Can't open library: -lcmoc-crt-ecb
Exit code from linker command: 1
Number of error messages from linker: 1

I'm totally stumped ... 
Don't worry about this too much Pierre -- unless you see something that is off. 

I might try placing some debug statements in the lwlink figure out why it's saying it can't open the library cmoc-crt-ecb -- I am guessing a lib is prepended before trying to open the lib?

OR I might go ahead and delete Cygwin and re-install it. 

here is the lib and bin folders ...

Hi James,

You could pass --verbose to cmoc to get more details.  In particular,
you should see a line like this:

    Linker command: lwlink --format=decb --output='tst1.bin'
    --script='tst1.link' --map='tst1.map'
    -L/usr/local/share/cmoc/lib -lcmoc-crt-ecb -lcmoc-std-ecb
    -lcmoc-float-ecb 'tst1.o'

The -L option specifies the directory where a bunch of lib*.a should
have been installed. A file named libcmoc-crt-ecb.a should appear there,
as well as libcmoc-std-ecb.a and libcmoc-float-ecb.a.

When you compiled and installed CMOC, did you pass any arguments to
"./configure", "make" or "make install"?

Could there be an old installation of CMOC in the executable path?
The "which cmoc" command would confirm the exact full path of the cmoc
command you are running.

Which versions of CMOC and LWTOOLS have you installed? (The latest CMOC
is 0.1.52. LWTOOLS >= 4.11 is required.)
