Rxvt-Unicode on Solaris 8 & gcc v.3.3.2

Mon Mar 27 21:40:36 CEST 2006

Hi Marc,

Thanks for your reply.

Disclaimer: I'm not a master C++ coder; I only know enough to be dangerous.

I looked in my gcc v.3.3.2 distribution, and in the
/usr/local/include/g++-v3/bits/std_cwchar.h file (see attachment) I
found the following:

// Get rid of those macros defined in <wchar.h> in lieu of real functions.
<...stuff...>
#undef mbrtowc

And then:

#if _GLIBCPP_USE_WCHAR_T
namespace std
{
  <...stuff...>
  using ::mbrtowc;

With little confidence, I tried setting _GLIBCPP_USE_WCHAR_T in the
Makefile; but that just resulted in a different failure mode.

I take from the above that my compilation environment is okay; but
perhaps not compatible with rxvt-unicode.

Do you know if rxvt-unicode has been built on Solaris 8 using gcc?  If
so, do you know whether or not v.3.3.2 is known to work correctly?

Thanks for any assistance you can offer.

Regards,
