Re: shared object libfl?

[Andrew S Halper]

Hmm. Although rather sketchily documented, it appears I might able to use
GLib to do this, so maybe having a dynamic libfl is not so much of a
priority after all:

OK, thanks. In the meantime I'll try work around it by writing my own
lexer.

Well, there hasn't been a release of flex in ~5 years. And back that
long ago, shared libraries were harder to do in a meaningfully
portable way.

But, I can see some potential downfalls with making libfl into a
shared library. MOstly they are the same reasons that one doesn't want
to make anything into a shared library. I'll think about this and see
what makes sense. If you'd like to post your question to
address@hidden and explain what your motivation is in more detail
for asking, you'll probably get more feedback that way. (help-flex@ is
the official channel for all things flex.)
