When I try to compile the newest version of Clisp on Ubuntu 8.04 I always get this error after running configure:
Configure findings:
FFI: no (user requested: default)
readline: yes (user requested: yes)
libsigsegv: no, consider installing GNU libsigsegv
./configure: libsigsegv was not detected, thus some features, such as
generational garbage collection and
stack overflow detection in interpreted Lisp code
cannot be provided.
Please do this:
mkdir tools; cd tools; prefix=`pwd`/i686-pc-linux-gnu
wget http://ftp.gnu.org/pub/gnu/libsigsegv/libsigsegv-2.5.tar.gz
tar xfz libsigsegv-2.5.tar.gz
cd libsigsegv-2.5
./configure --prefix=${prefix} && make && make check && make install
cd ../..
./configure --with-libsigsegv-prefix=${prefix} --with-readline --with-unicode --with-module=i18n --with-module=gdbm --with-module=pcre --with-module=readline --with-module=regexp
If you insist on building without libsigsegv, please pass
--ignore-absence-of-libsigsegv
to this script:
./configure --ignore-absence-of-libsigsegv --with-readline --with-unicode --with-module=i18n --with-module=gdbm --with-module=pcre --with-module=readline --with-module=regexp
I've tried doing as requested, but it didn't help: it seems to ignore the --with-libsigsegv-prefix option. I also tried putting installing libsigsegv in a standard location (/usr/local). Oh, and of course, Ubuntu tells me that libsigsegv and libsigsegv-dev are installed in the system.
I'd really like to be able to compile this version of Clips, as it introduces some serious improvements over the version shipped with Ubuntu (I'd also like to have PCRE).
