Cscope error: cscope: cannot read list size from file cscope.out

Question

There's an exact questioned that is already here !, but with no detailed solution, so asking again. I followed this ! tutorial:

find . -name "*.c" -o -name "*.cpp" -o -name "*.h" -o -name "*.hpp" > cscope.files
cscope -q -R -b -i cscope.files
cscope -d

when I execute the last command, I get an error: cscope: can not read list size from file cscope.out.

files sizes:

$ ls -l | grep cscope
-rw-r--r--   1 tnsharma  wheel     8230153 May 29 11:13 cscope.files
-rw-r--r--   1 tnsharma  wheel   280810496 May 29 11:39 cscope.in.out
-rw-r--r--   1 tnsharma  wheel  3471526675 May 29 11:39 cscope.out
-rw-r--r--   1 tnsharma  wheel  1929521640 May 29 11:39 cscope.po.out

Any idea how to make this work? -Thanks

Update: I am able to use cscope in the sub folders. But don't know how to link the cscope.out files across the sub folders to make it global.

Answer 1

Your cscope.out is too large for it to work.

Try reducing the number of files that you parse when doing cscope -R or -b by creating a cscope.files files.

Answer 2

I have given a solution in case where your directory name , or the path of the directory has space(s) . Rename directory without space(s) and retry. Check this https://stackoverflow.com/a/30423629/3936129
