[CM] Re: Compiling FTH on OSX progress

[Charles Turner]

Hi Michael-

I've made a little progress in troubleshooting the OSX compile of FTH.
It seems to be centered around some confusions with the readline
library.

I've been configuring with: ./configure --without-gmp

configure picks up on readline.h and history.h (which is a symlink to
readline.h) in OSX's /usr/include directory. There's some issue with
readline support on OSX, eg:

<http://lua-users.org/lists/lua-l/2004-09/msg00353.html>

but as of now, I'm unclear why OSX has these includes if there's no
support. (A topic for further research...)

My first thought was to simply use --with-readline-prefix=/sw in order
to reference the Fink install of GNU readline that I have. This seemed
to go well until the link stages of FTH's build, where I got a bunch of
errors.

I decided to try to build without readline as a test: ./configure
--without-gmp --without-readline and got the below-- slightly less angry
than the compile --with-readline-prefix, but exhibiting many of the same
errors:

make[2]: *** [fth-static] Error 1
make[1]: *** [fth] Error 2
make: *** [all] Error 2

I'll start to look at some of these undefined symbols. (why
_gmp_asprintf if I'm not building with gmp?) and see if I can get a good
build.

Take care and thanks again!
