[OctDev] Build problems for octave-forge with 2.1.53

[David B. <Dav...@mo...>]

Here are the list of build problems I have with octave-forge CVS at the
moment.

extra/mex/mex.cc
----------------

mex.cc: In member function `mxArray* mxArray::field(const std::string&, int) const':
mex.cc:377: error: no match for 'operator[]' in '*this->mxArray::pmap[key]'
mex.cc: In member function `void mxArray::field(const std::string&, int, mxArray*)':
mex.cc:383: error: no match for 'operator[]' in '*this->mxArray::pmap[key]'
mex.cc: In member function `mxArray* mex::make_value(int, int, const string_vector&)':
mex.cc:551: error: call of overloaded `assign(std::string, octave_value_list&)' is ambiguous
/opt/octave-2.1.53/include/octave-2.1.53/octave/oct-map.h:123: error: candidates are: Octave_map& Octave_map::assign(const std::string&, const octave_value&)
/opt/octave-2.1.53/include/octave-2.1.53/octave/oct-map.h:125: error:                 Octave_map& Octave_map::assign(const std::string&, const Cell&)
make: *** [mex.o] Error 1

This appears is not that clear to me how to fix this, especially the last
error, the first two will need a change like

#if HAVE_MAP_IDX_OP
      return __mex->make_value((*pmap)[key](index));
#else
      return __mex->make_value((*pmap).contents(key)(index));
#endif

with the appropriate logic to select the right version in configure.add.
This is ugly as it introduces cruft for backwards compatiability.

However, the last error is a pain as this function appears to have
been deleted and replaced with different versions. Its not clear to
me how to fix this for 2.1.53.


main/miscellaneous/listen.cc
----------------------------

listen.cc: In function `void process_commands(int)':
listen.cc:331: error: `bind_global_error_variable' undeclared (first use this function)
listen.cc:331: error: (Each undeclared identifier is reported only once for each function it appears in.)
listen.cc:347: error: `clear_global_error_variable' undeclared (first use this function)
listen.cc: In function `octave_value_list Flisten(const octave_value_list&, int)':
listen.cc:564: error: no matching function for call to `unwind_protect::save_bool(int*, int&)'
/opt/octave-2.1.53/include/octave-2.1.53/octave/unwind-prot.h:103: error: candidates are: static void unwind_protect::save_bool(bool*, bool)
make: *** [listen.o] Error 1

The functions bind_global_error_variable and clear_global_error_variable 
have been deleted, and __error_text__ must be manipulated directly. The last
error is due to the fact that buffer_error_messages is now type int, and
so the incorrect unwind_protect function was called. This seems that it will
also require a configuration variabkle to select between versions.

Again, I'm not quite sure of the fix as I don't use this code. However, as
these two functions don't build with 2.1.53, they should be fixed prior to
an octave-forge release....

Cheers
David
