I am trying to test DBI/DBD with Sybase 15. The system currently works with Perl 5.8.5 and a similarly old DBD.

First, I built 5.8.9, the last saved version of the 5.8 tree, and 5.12.1, the most recent (64 bit) version. Each is in its own directory:

/opt/tools/perl5.8.9

/opt/tools/perl5.12.1

setting the path to /opt/tools/perl5.8.9/bin, I installed DBI-1.613_70 that worked no problem. Same with perl5.12.1

Then, with gcc-3.4.6 on RedHat AS 4, or Sun's compiler on Solaris, I get the following error, with either version. I'm an experienced C++ programmer, I just don't have enough experience with perl interfacing to C, can anyone tell me what to do?

Here's the line of code:

void
_date_fmt(dbh, fmt)
    SV *        dbh
    char *      fmt
    ALIAS:
    syb_date_fmt     = 1
    CODE:
    D_imp_dbh(dbh);
    ST(0) = syb_db_date_fmt(dbh, imp_dbh, fmt) ? &sv_yes : &sv_no;
