readline installation problem

[Jian Qiu]

Hi, I tried to install python2.4.2. Unfortunately building 'readline'
extension failed.

Here is what I got: (It is a bit long. If you are impatient, please look
at the end where it reports the warning.)

It complains that libreadline.so. 5 does not exist. However, I have
libreadline.so. 5 installed at /gs/home/jianq/lib which is among the
linking path (-L/gs/home/jianq/lib).

I have been struggling with this for a long time and sincerely hope that
someone can help me with this.

Thanks,

Jian

Re: readline installation problem

Hi Jian,

I just struggled with the same problem - seems the python 2.4.2 does
not recognise readline 5

I finally "solved" the problem by installing readline 4.2, and
explicitly pointing out to configure where the readline library is

../configure --with-libs=/usr/local/lib/libreadline.a

That finally made it work ...

Cheers
Jesper
