1. DDD 3.3.1 doesn't seem to compile out of the box when un-tared on a standard RH7.2 linux system. Note, the comiler version si gcc 2.96.

2.  The symptiom is:

In file included from ddd.C:182:
AgentM.h: In method `AgentManager::AgentManager (void (*) (...))':
AgentM.h:84: cannot convert `void (*) (...)' to `void (*) (int)' for
argument `2' to `signal (int, void (*) (int))'
AgentM.h:86: cannot convert `void (*) (...)' to `void (*) (int)' for
argument `2' to `signal (int, void (*) (int))'
ddd.C: In function `int main (int, char **)':
ddd.C:2234: cannot convert `void (*) (...)' to `void (*) (int)' for
argument `2' to `signal (int, void (*) (int))'
make[1]: *** [ddd.o] Error 1
make[1]: Leaving directory `/.automount/mermaid/root/u/data/src/ddd-3.3.1/ddd'
make: *** [all-recursive] Error 1

3.  The fix is:

change the line in config.h that matches from:

FROM: #define SIGHANDLERARGS ...
TO:   #define SIGHANDLERARGS int

4.  Make as usual.

5. This showed up on the mailing list archives in 2001 but no-one ever fixed it. I'm guessing a configure needs to be modified but am not sure how. Note, if you modify the config.h file that MUST happen after you have executed .configure.


6.  See PROBLEMS file:

SunOS 4.1 and Sun C++
---------------------

Reported by:  Franklin Chen <address@hidden>

    On SunOS 4.1.x, with Sun C++ 4.0.1, `config.h' needs to end up with
        #define SIGHANDLERARGS int, ...
    rather than
        #define SIGHANDLERARGS int
    to avoid compile errors in a number of source files.


This is the same except it needs to end up as "int" not "int, ..." (I think!  
Though this solution might work too???)

Thanks,

Tristan Gross
