Hi,
I have recently upgraded libfreetype from 2.1.10 to 2.3.9 and I want to know if there is any function prototype change in this migration.

I have two folders fld1, fld2. The fld1 contains all the older header files whereas fld2 contains the newer header files.

At present I am doing manual diff between fldr1 and fldr2, to check the prototype changes, which is troublesome.
e.g.
diff fldr1/ftdriver.h fldr2/ftdriver.h
shows the changes in ftdriver.h during transition. (this includes changes in comments also, so need further manual checks to all functions)

Is there any easier way/tool to get the changes in prototypes if any ?




Thanks,

I tend to use side-by-side view in diff when I'm trying to find big differences between files. You can do a

to get the effect on a 140 character wide terminal. It works just like a merge, with < | > characters showing lines only in the original, lines that have changed, but are noticeably the same line, or lines unique to the second version, respectively.

There was also a Linux Journal article about using a program called meld to do visual diffs. I've not used this, but it caught my eye yesterday.

(Apparently, I'm not allowed to post links because I've not posted here before and I may be a spam bot :-)

Hi,
But this means manually checking each of them.
So if we have hundreds of files to check, then it's not useful.

I am in search of some automated tool.

Not to keep harping on diff, but you can also do a recursive directory comparison with -r, and exclude the types of files (source, not headers, makefiles) you don't want to see (--exclude-"*.c")
