HOWTO

# libffi 3.4.8
# ============
# Slackware 14.0: libffi 3.0.11
# Slackware 14.1: libffi 3.0.13
# Slackware 14.2: libffi 3.2.1
# Slackware 15.0: libffi 3.3

# If you want to remove libffi, or clean up files from an old version before
# installing this one, skip down to the bottom for instructions.

# Prerequisites:
# DejaGnu's runtest (for 'make check')

# libffi-announce mailing list
# libffi-discuss mailing list
# GitHub Releases v3.4.8

# Get the tarball
cd
test -f installed/libffi-3.4.8.tar.gz &&
mv installed/libffi-3.4.8.tar.gz .
test ! -f libffi-3.4.8.tar.gz &&
wget https://github.com/libffi/libffi/releases/download/v3.4.8/\
libffi-3.4.8.tar.gz

# Verify tarball w/ sha256sum:
# (from mine, so this only proves yours is the same)

# Extract the source
mkdir -p -m 0700 ~/src

# I use /usr/include/ffi here because of things like Python < 3.12.0 which
# use setup.py  It is not so good at finding includes and libraries.
# If /usr/include/ffi is where ffi.h and ffitarget.h are, and:
# pkg-config --cflags-only-I libffi
# outputs that, then you're good.
# If they are in /usr/include and:
# pkg-config --cflags-only-I libffi
# outputs nothing, then it will fail with a useless error similar to
# File not found /usr/include/*.h
# Python >= 3.12.0 does not use setup.py any more.

# Build it
make

# Check the build
make check

# Become root to install it
su

# WARNING: make may be linked with libffi, so if you will be removing
# the Slackware package below, you may want to be safe and save a copy
# of /usr/lib*/libffi.so.* to copy back in there manually

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

## If 'make' fails here, because it is linked with libffi.so.6
## (ldd /usr/bin/make|grep libffi) and you just
## removed it, you can do something like this in a pinch (maybe):
# cp -a x86_64-pc-linux-gnu/.libs/libffi.so.8.1.4 /usr/lib64/
# ln -s /usr/lib64/libffi.so.8.1.4 /usr/lib64/libffi.so.6
# ldconfig

# If you used --enable-static=no above, remove old version static library
rm -f /usr/lib*/libffi.a

# Remove old version docs
find /usr/doc -maxdepth 1 -type d -name "libffi-*" -exec rm -r {} \;
test -d /usr/doc/libffi

# Be aware that libffi.info will be installed in to /usr/info,
# but you may already have a libffi.info.gz from the GCC Slackware package
# (so use the full path: 'info /usr/info/libffi.info')

# If you used --includedir=/usr/include before (the default), remove
# the old ones
( cd /usr/include ; rm -f ffi.h ffitarget.h )

# Install it
make install
ldconfig

# Create symlinks for anything that assumes the includes are in /usr/include
( cd /usr/include
  rm -f ffi.h ffitarget.h
  ln -s ffi/ffi.h
  ln -s ffi/ffitarget.h )

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