[Coco] CMOC linking error

[James Ross]

Hi Pierre ... It was something to-do w/ Cygwin paths … I just don't know what.

If I modify readfiles.c in LWLINK just before line #105 --> f = fopen(tf, "rb");

f = fopen("/usr/local/share/cmoc/lib/libcmoc-crt-ecb.a", "rb"); --> FAILS (and stat does not find file either).  

f = fopen("C:\\Cygwin64\\usr\\local\\share\\cmoc\\lib\\libcmoc-crt-ecb.a", "rb"); --> SUCCESS

I thought it might had to do w/ Cygwin being on the C: drive and the test project being on the D: drive but that was NOT it … 

SO … I deleted and re-installed Cygwin. Rebuilt and installed LWASM and CMOC again. 

And now it’s working just like it should!

CMOC is cool, btw. 

Thanks for your help.

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.)
