RE: Follow up: What else....

[Keith Knapp]

Hey Rocky and everyone else, 
 
1. I thought of and checked file permissions immediately after sending the
last email and they are not the problem.

2. I ran strace and it returns:
        -1 ENOENT (No such file or directory)
for every location of the file ddd.vsl it tries, and as I mentioned before
it tries about 20 different spots. I still have the file in 2 locations.....


It doesn't make sense. I get no error messages for any of the other files in
the vsllib directory. I would have thought that if ddd.vsl doesn't load
other modules may have issue too.

The obvious thing that comes to mind is file permissions. :-)

If you want the hacker way to verify the file is getting opened properly or
not, you could run strace and look for the return code on the stat() or
stat64() system call

write(5, "#  Trying \"/home/rocky/.ddd/vsll"..., 44) = 44
stat64("/home/rocky/.ddd/vsllib/ddd.vsl", 0xbf8d1a5c) = -1 ENOENT (No such
file or directory) stat64("/home/rocky/.ddd/vsllib/ddd.vsl", 0xbf8d1a5c) =
-1 ENOENT (No such file or directory) write(5, "#  Trying
\"/usr/local/share/ddd-"..., 64) = 64
stat64("/usr/local/share/ddd-3.3.12-test6cvs/vsllib/ddd.vsl",
{st_mode=S_IFREG|0644, st_size=8209, ...}) = 0
