# configure script for ogpipes. This script is needed only if
# you wish to build a shared library and your system supports them,
# of if you need special compiler, flags or install directory.
# Otherwise, you can just use directly "make test; make install"
#
# To create a shared library, use "configure --shared"; If the primitive
# shared library support provided here does not work, use
# ftp://prep.ai.mit.edu/pub/gnu/libtool-*.tar.gz
#
# To impose specific compiler or flags or install directory, use for example:
#    prefix=$HOME CC=cc CFLAGS="-O4" ./configure
# or for csh/tcsh users:
#    (setenv prefix $HOME; setenv CC cc; setenv CFLAGS "-O4"; ./configure)
# LDSHARED is the command to be used to create a shared library

# Incorrect settings of CC or CFLAGS may prevent creating a shared library.
# If you have problems, try without defining CC and CFLAGS before reporting
# an error.
