Therion doesn't compile with g++3.3 which means it is (partly) responsible for holding back the Debian transition to gcc3.3. I don't understand C++ to an embarassing degree so I post the error here in the hope that someone who does can explain what might be wrong: Looks like it seems to think some standard library function is missing? g++ -c -Wall -D_GNU_SOURCE -DTHLINUX -g -Wall -O2 -o thdata.o thdata.cxx thdata.cxx: In member function void thdata::insert_data_leg(int, char**)': thdata.cxx:1223: error: no matching function for call to std::list<thdataleg, std::allocator<thdataleg> >::insert(std::_List_iterator<thdataleg, thdataleg&, thdataleg*>)' /usr/include/c++/3.3/bits/list.tcc:88: error: candidates are: std::_List_iterator<_Tp, _Tp&, _Tp*> std::list<_Tp, _Alloc>::insert(std::_List_iterator<_Tp, _Tp&, _Tp*>, const_Tp&) [with _Tp = thdataleg, _Alloc = std::allocator<thdataleg>] /usr/include/c++/3.3/bits/stl_list.h:831: error: void std::list<_Tp, _Alloc>::insert(std::_List_iterator<_Tp, _Tp&, _Tp*>, unsigned int, const _Tp&) [with _Tp = thdataleg, _Alloc = std::allocator<thdataleg>] thdata.cxx: In member function void thdata::set_data_fix(int, char**)': thdata.cxx:1642: error: no matching function for call to std::list<thdatafix, std::allocator<thdatafix> >::insert(std::_List_iterator<thdatafix, thdatafix&, thdatafix*>)' /usr/include/c++/3.3/bits/list.tcc:88: error: candidates are: std::_List_iterator<_Tp, _Tp&, _Tp*> std::list<_Tp, _Alloc>::insert(std::_List_iterator<_Tp, _Tp&, _Tp*>, const_Tp&) [with _Tp = thdatafix, _Alloc = std::allocator<thdatafix>] /usr/include/c++/3.3/bits/stl_list.h:831: error: void std::list<_Tp, _Alloc>::insert(std::_List_iterator<_Tp, _Tp&, _Tp*>, unsigned int, const _Tp&) [with _Tp = thdatafix, _Alloc = std::allocator<thdatafix>] thdata.cxx: In member function void thdata::set_data_equate(int,char**)': thdata.cxx:1718: error: no matching function for call to std::list<thdataequate, std::allocator<thdataequate> >::insert( std::_List_iterator<thdataequate, thdataequate&, thdataequate*>)' /usr/include/c++/3.3/bits/list.tcc:88: error: candidates are: std::_List_iterator<_Tp, _Tp&, _Tp*> std::list<_Tp, _Alloc>::insert(std::_List_iterator<_Tp, _Tp&, _Tp*>, const _Tp&) [with _Tp = thdataequate, _Alloc = std::allocator<thdataequate>] /usr/include/c++/3.3/bits/stl_list.h:831: error: void std::list<_Tp, _Alloc>::insert(std::_List_iterator<_Tp, _Tp&, _Tp*>, unsigned int, const _Tp&) [with _Tp = thdataequate, _Alloc = std::allocator<thdataequate>] thdata.cxx: In member function void thdata::set_data_station(int, char**, int) ': thdata.cxx:1731: error: no matching function for call to std::list<thdatass, std::allocator<thdatass> >::insert(std::_List_iterator<thdatass, thdatass&, thdatass*>)' /usr/include/c++/3.3/bits/list.tcc:88: error: candidates are: std::_List_iterator<_Tp, _Tp&, _Tp*> std::list<_Tp, _Alloc>::insert(std::_List_iterator<_Tp, _Tp&, _Tp*>, const _Tp&) [with _Tp = thdatass, _Alloc = std::allocator<thdatass>] /usr/include/c++/3.3/bits/stl_list.h:831: error: void std::list<_Tp, _Alloc>::insert(std::_List_iterator<_Tp, _Tp&, _Tp*>, unsigned int, const _Tp&) [with _Tp = thdatass, _Alloc = std::allocator<thdatass>] make[1]: *** [thdata.o] Error 1 make[1]: Leaving directory /home/wookey/survex/therion/therion-0.2.9/src' -- Wookey -- Aleph One Ltd, Bottisham, CAMBRIDGE, CB5 9BA, UK Tel +44 (0) 1223 811679 work: http://www.aleph1.co.uk/ play: http://www.chaos.org.uk/~wookey/
