Re: configure script - libsigsegv detection broken?

[edgar <edg...@we...>]

Hi Vladimir,

Tested on Debian 5 (lenny) just half an hour ago:

This is how I compile CLISP CVS HEAD on Debian 5 (lenny):

My cvs checkout directory from today's CVS HEAD is:
/home/edgar/Downloads/clisp/clisp-2010-09-25/...

The libsigsegv tarball is in:
/home/edgar/Downloads/clisp/libsigsegv-2.8.tar.gz

 From the cvs-checkout directory I run this shell-script:

--- configure shell script ---
LIBSIGSEGV=libsigsegv-2.8
CONFIG_OPTS=--with-module=clx/new-clx
BUILD_DIR=linux-build

# make a "tools" directory inside the cvs checkout directory
mkdir tools
cd tools

# define "../cvs-checkout/tools/i686-pc-linux-gnu" as the libsigsegv prefix
# /home/edgar/Downloads/clisp/clisp-2010-09-25/tools/i686-pc-linux-gnu
prefix=$(pwd)/i686-pc-linux-gnu

# copy and unpack the libsigsegv tarball
cp ../../${LIBSIGSEGV}.tar.gz ./
tar xfz ${LIBSIGSEGV}.tar.gz

# in the libsigsegv directory, configure, make, and install libsigsegv
cd ${LIBSIGSEGV}/
./configure --prefix=${prefix} && make && make check && make install

# back to CLISP's cvs checkout directory
cd ../../

# configure CLISP
./configure --with-libsigsegv-prefix=${prefix} $CONFIG_OPTS $BUILD_DIR

# make sure we have enough stack space
ulimit -s 16384
--- end of configure shell script ---

At the end of ./configure CLISP tells me:

Configure findings:
FFI:        yes (user requested: default)
readline:   yes (user requested: default)
libsigsegv: yes

Then I go into the linux-build-directory:

cd linux-build
# edit the Lisp configuration
make
make check
sudo make install

libsigsegv found, all checks passed, CLISP works.

Please note that libsigsegv has been compiled with exactly the same
version of tools and libraries like CLISP (I sometimes in the past
had troble if this was not the case, but unfortunately can't tell
the exact reason why), and that libsigsegv had been installed in
"../cvs-checkout/tools/i686-pc-linux-gnu", as suggested in the CLISP
INSTALL docs. I haven't tested if the build fails if libsigsegv is
installed in "/usr/lib" or "/usr/local/lib".
