egcs and flex source/ template database/ 2.7.2 -> 2.8/ecgs stuff

egcs and flex source/ template database/ 2.7.2 -> 2.8/ecgs stuff

[Johannes Behr]

Hi,

I'm new to egcs and I'm actually not a 'compiler-hacker' (However I would
consider myself a quite experienced C/C++ programmer). I hop it's OK to ask some
'user' question.

I installed the 1.0.1 package on my Linux RH 4.2 system and compiled
some tiny test programs with success but if I try to compile my 'big' 
system, I get always the following error message in the in the lexer.cpp
file.

----------------------------------------------------------------------

lexer.Linux_ECC.o: In function `yy_get_next_buffer(void)':
/opt/src/avalon/lexer.cpp:3540: undefined reference to `_IO_getc'      

----------------------------------------------------------------------

lexer.cpp is a file created by flex (version 2.5.4)? Any Idea ?

But now my BIG PROBLEM: I use heavily STL and own template classes and my 
binary is right now 33 meg (on IRIX 6.2 even 54) with gnu 2.7.2. I _need_
some kind of 'template database'. I know, the native Solaris and IRIX
compiler have 'some kind' of template database but I would like to use
gcc or now egcs. Is there a 'template database' in egcs ?

One more general question: I have found some info about the differences of
egcs and 2.8.0 but is the a info-page about what's new in egcs or 2.8.0 
compared to 2.7.2 (beside the STL and ANSI C++ stuff)

Thanks for reading
  Johannes

Please get libc 5.4.44 or above.

The pre-compiled binary for 5.4.44 has no NYS. You
need to compile NYS yourself.
