The only way to know for sure is to try it out! Attached is a
proof-of-concept patch which adds the --with-libedit flag to the
readline package's autoconf scripts.
* PROOF OF CONCEPT: add --with-libedit flag to allow building a
minimal version of the library against libedit.
M ./HsReadline_cbits.c +2
M ./System/Console/Readline.hsc -1 +50
M ./aclocal.m4 +6
M ./configure.ac -4 +10
With this patch (and a small, unrelated hack to statically link gmp) I
was able to build a version of ghc which only depends on the dynamic
libraries installed on OS X 10.4 by default:
$ otool -L ghc-6.9.20071221
ghc-6.9.20071221:
/usr/lib/libedit.2.dylib (compatibility version 2.0.0, current
version 2.0.0)
/usr/lib/libncurses.5.4.dylib (compatibility version 5.4.0,
current version 5.4.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0,
current version 88.3.9)
I played around with completion of filenames, modules, identifiers and
flags in ghci, and it all seems to be working fine.
Best,
