[Texmacs-dev] texmacs-1.0.1.6 and make_scheme_widget_rep

[Martin Costabel]

When compiling texmacs-1.0.1.6 under Mac OSX (gcc-3.1), I get the 
following error on the final linker line:

c++ Objects/analyze.o [SNIP] -o 
/sw/src/texmacs-1.0.1.6-1/TeXmacs-1.0.1.6-src/TeXmacs-1.0.1.6/bin/texmacs.bin
ld: Undefined symbols:
vtable for make_scheme_widget_rep
make[1]: *** 
[/sw/src/texmacs-1.0.1.6-1/TeXmacs-1.0.1.6-src/TeXmacs-1.0.1.6/bin/texmacs.bin] 
Error 1
make: *** [STATIC_TEXMACS] Error 2

My C++ knowledge is very limited and does not include vtables. Could 
someone explain how to overcome this? Some compiler switch?

Here is how one of the object files containing the undefined symbol was 
compiled:

c++ -I./Basic/Data -I./Basic/Misc -I./Basic/System -I./Basic/Types 
-I./Resource -I./Window -I./Typeset -I./Edit -I./Convert -I./Texmacs 
-I./Guile -I/sw/include -Wall -Wno-return-type -O2 -fno-default-inline 
-fno-inline -fno-rtti -fno-exceptions -I/sw/include -c 
./Guile/Scheme/object.cc -o Objects/object.o
