'''Problem'''
I'm running Mac OS X Tiger (10.4.6) and trying to build GHC 6.4.2 (using
GCC 4.0.1 and GHC 6.4.1) and I'm ran into a problem where certain
constants (e.g., UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END) are not
found, causing compilation to stop. The same issue occurred for at least
one other user with GHC 6.5; unfortunately, I can't find the post again.
'''Solution?'''
Tiger ships with a NetBSD partial version of the readline library in /usr.
Unfortunately, this file lacks a lot of the functionality in the GNU
readline and is not compatible enough.
To get around this:
# Download and decompress the GNU readline library, v5.1 tarball (other
version may work)
# cd <readline source dir>
# ./configure
# make
# sudo make install #Installs to /usr/lib/include and /usr/lib/bin
# cd <GHC source dir>
# export LDFLAGS=-L/usr/local/lib # tell linker to use GNU version of
readline
# export CPPFLAGS=-I/usr/local/include # tell compiler to use GNU version
of readline
# ./configure --disable-openal --disable-alut # Audio disabled because of
unrealted bug
# make
# sudo make install
This should do it. Steps 7 and 8 could cause problems because the compile
will look for ALL libraries in /usr/local before looking in /usr.
The compilation is successful and ghc and ghci run; however,
Unfortunately, I won't be able to test the results for some time.
'''Follow-Up?'''
It should be possible to detect the lack of readline through the configure
process. The NetBSD bad readline.h file results in the following
statements:
<pre>
checking for rl_erase_empty_line in -lreadline... no
checking for rl_free_undo_list in -lreadline... no
</pre>
The GNU readline 5.1 library results in the following statements:
<pre>
checking for rl_erase_empty_line in -lreadline... yes
checking for rl_free_undo_list in -lreadline... yes
</pre>
It may be possible to create a test in the configure file by looking at
the platform and these two functions. Also, the platform-specific
documentation could be updated.
