no it did not solve the problem but I looked into the code -
I usualy work in C so im not used to C++ and I'm not that
skilled programer. Hope that dosent disturb (and excuse my
english). I think i found the header in the file
boost/boost/crc.hpp (content at end of mail) - but i dont
find the code.
Looking at the coments it seems to be from the boost
library. This makes me consither if Lyx has a not mentioned
dependency on this boost library - or that its included
somewhere in the source - i dont know where - and that I
have to link to its objectcode in the linking.
Rember that MacOsX 10.2/Darwin is based on FreeBSD and
gcc-3.1 compiler. I am just learning this envirement - but
usualy almost evrything but the compiler have to be ported
to get GNU programs to work. I am consithering to compile
lyx on my linux machine - just to see if i get the same
behavior. Should there bee a -lboost switch?
I can download and compile boost - but should that bee
right?
Greetings
