Summary: Build of readline fails
Initial Comment:
I was attempting to compile Python-2.3.5 under Fedora
Core 4:
Python 2.3.5 (#14, Mar 14 2006, 17:57:17)
[GCC 4.0.2 20051125 (Red Hat 4.0.2-8)] on linux2
and needed it to have readline support
No matter how I compiled it, the readline module was
never built, and of course readline functionality did
not work.
I tried ./configure --with-readline=/usr and a couple
of other configure options that I thought would help,
but nothing worked. Finally, I tried:
make Modules/readline
which gave the error:
gcc -pthread -fno-strict-aliasing -DNDEBUG -g -O3 -Wall
-Wstrict-prototypes -I. -I./Include
-L/home/sweidman/Applications/Python-2.3.5
Modules/readline.c -o Modules/readline
Modules/readline.c:96: error: static declaration of
âhistory_lengthâ follows non-static declaration
/usr/include/readline/history.h:242: error: previous
declaration of âhistory_lengthâ was here
make: *** [Modules/readline] Error 1
So without knowing what I was really doing, I commented
out the definition of history_length at
Modules/readline.c:96
After making that change, Python-2.3.5 compiled and ran
fine with readline support working; i.e. "import
readline" gave no errors and the arrow keys bring back
the last command.
So is this a bug or a quirk on my platform or something
else I'm doing wrong?
Thanks for the great software!!

Python 2.3 isn't supported any longer. In the current
version, it looks like history_length was renamed to prepend
an underscore (ie, the name became: _history_length). This
was presumably to fix the same problem. The name also
changed in write_history_file(), set_history_length(), and
get_history_length().
It's not so much anything you are doing wrong, just a
compatability problem, since FC4 is quite a bit newer than
Python 2.3. If you upgrade to Python 2.4, you shouldn't
have the problem, or you can run with your local modification.
