I will, this issue might concern other users.

Yes, I know, I have compiled gcc-3.2.1 myself and plplot_octave (not plpl=
ot)=20
does not compile. It looks like that  class vector string is missing:

> more /usr/include/g++/string
    // Main header for the -*- C++ -*- string classes.

    #ifndef __STRING__
    #define __STRING__

    #include <std/bastring.h>

    extern "C++" {
    typedef basic_string <char> string;
    // typedef basic_string <wchar_t> wstring;
    } // extern "C++"

    #endif

> rpm -qf /usr/include/g++/string
    libgpp-2.95.3-216

So, the new gcc-3.2.1 does not has libg++, that is where "string" comes f=
rom.

I will correct this in the future, but for now you can only use gcc-2.95.=
x.=20
(or compile libg++ if you find it -- it's now kind of obsolete, I think).=
 I'm=20
pretty sure that octave 2.1.40 compiles with gcc-2.95.x, so it's your las=
t=20
resort.

Thanks,
Joao
