Hi Vasco Costa,
Yes -z 1 did it. :)
Now fopen() throws an error! Function clt_read_code() in primitiive_util.c
fopen() returns a NULL. I included <errno.h> and printed the error as
described here
http://stackoverflow.com/questions/8633909/what-is-the-reason-for-fopens-failure-to-open-a-file
The error is 2 which means "No such file or directory" according to
http://www.thegeekstuff.com/2010/10/linux-error-codes/
This is rather puzzling because I can see solver.cl present in the same
directory as primitive_util.c. Moreover, fopen() is a function that I've
used time and time again and I haven't this kind of error before. I also
verified that the file has read access.
Thank you for your patience! I'm just running into issue after issue. I
really appreciate your guidance.
Best,
Param
