# Configure the build for 64-bit
test $(uname -m) = 'x86_64' &&
./configure --prefix=/usr --docdir=/usr/doc/mpfr --infodir=/usr/info \

# Build it
make

# Generate documentation in various formats
# doc/mpfr.pdf doc/mpfr.dvi doc/mpfr.ps doc/mpfr.html/index.html
make pdf
make dvi
make ps
make html

# Check the build
make check

# Become root to install it
su

## Save a copy of whatever /usr/lib*/libmpfr.so.* that you have now before
## removing the Slackware package.  You may find that things like this:
# ldd /usr/libexec/gcc/x86_64-slackware-linux/*/cc1
## ...are looking for libmpfr.so.4 but the new one installed here is
## libmpfr.so.6  So, either put the old one back in there, or try a symlink
# ( cd /usr/lib64
#   test ! -L libmpfr.so.4 && ln -s libmpfr.so libmpfr.so.4
#   ldconfig )

# Remove the Slackware package, if there is one
test -x /sbin/removepkg && /sbin/removepkg mpfr

# Install it
make install
ldconfig

# If you generated pdf, dvi, ps, html documentation, install it
# in to /usr/doc/mpfr/
make install-pdf
make install-dvi
make install-ps
make install-html

# Make sure your non-root user can remove the source later
chown -R $(logname) .
chmod -R u+w .

# Become yourself again
exit

# Save the source for later
cd
mkdir -p -m 0700 installed
rm -f installed/mpfr-*.tar.*
mv mpfr-4.2.1.tar.xz installed/

# If you ever want to uninstall MPFR, this should do it:
cd
su
test -d src/mpfr-* && ( cd src/mpfr-* ; make uninstall )
test -d /usr/doc/mpfr && rm -f /usr/doc/mpfr
( cd /usr/include ; rm -f mpfr.h mpf2mpfr.h )
rm -f /usr/info/mpfr.info /usr/lib*/libmpfr.* \
/usr/lib*/pkgconfig/mpfr.pc
ldconfig
exit
find ~/src -maxdepth 1 -type d -name "mpfr-*" -exec rm -r {} \;
