I've just installed perl 5.8.1 and while trying to reinstall DBD::Informix,

I've traced the source of the compile error back to the SvOK_off macro
inside sv.h. It was changed between perl 5.8.0 and perl 5.8.1, redefining
SvOK_off

#define SvOK_off(sv) (SvFLAGS(sv) &= ~(SVf_OK|SVf_AMAGIC| \ SVf_IVisUV|SVf_UTF8), \ SvOOK_off(sv))

as

#define SvOK_off(sv)            (assert_not_ROK(sv)                     \
                                 SvFLAGS(sv) &= ~(SVf_OK|SVf_AMAGIC|    \
                                                  SVf_IVisUV|SVf_UTF8), \
                                                        SvOOK_off(sv))

I've come across this critter, and couple of other nasties -- well, I think it was this one. I changed it so that it does an assignment of PL_sv_undef -- IIRC sv_setsv(sv, &PL_sv_undef);

I'm not sure what that breaks.

The other problem I had (on Solaris 8) was with loader/linker options (using GCC 3.3.1). The combination of -z ignore -z combreloc and -z lazyload was not good; I ended up dropping the -z lazyload and it seemed to work OK (that was with RC4; I built the final version without the -z lazyload, but I've not yet installed it, much less augmented it with the extra modules).


I ran across the same compile error when trying to compile
an older DBD::Informix (1.04.PC1), so it does appear to be a problem
with any calls made to SvOK_off under this system.

Perhaps simply removing the assert_not_ROK() macro call from sv.h would be good
enough? Though I'm not certain about the full impact that would have.

Any thoughts? Or am I a fool for installing perl 5.8.1 without waiting for
module authors to catch up?

Slightly brave, but not outrageously foolhardy.
