Re: Compile error: Digital UNIX

Hi Robert,

Check "man localtime" on your Digital UNIX system, and look at the type of the argument to localtime(). (You may have to use "man -s2 localtime" or "man 2 localtime" to get the man page for the C function. If it doesn't find "localtime", try "ctime" instead.)

On my Solaris system, the argument type is "const time_t *". This is defined in /usr/include/time.h as a typdef to long:

  typedef long time_t;

However, msg2archive.c declares "clk" as a long, not a time_t.

To fix this, simply cast the value of "&clk" to the correct value. Because time_t and long are essentially the same (under Solaris), this will generally work.

  now = localtime((const time_t *) &clk);

***NOTE***: The type, time_t, may be defined differently (as "long long") on 64-bit architectures!!! A better fix for msg2archive.c would be to use this line in place of "long clk;" near the top of the file:

time_t clk;

I would try changing the definition of "clk" first, then trying the cast second.
