About thousand of error.
I'm using ubuntu 8.04. Above error leads "tools/perl/Makefile" can't find the libperl-dev and define "NO_LIBPERL", but I have installed "libperl-dev".
Did you ever encounter this error?
Thanks.
No, I haven't seen it, but I'm using ubuntu 8.10, which has perl
v5.10.0.
ubuntu 8.04 uses what's apparently an ancient version of perl, 5.8,
which is I'm guessing where the problem is - I'll have to look intoAnother compile error:
getting things working with 5.8 in any case...
