Comment (by leif):
Ahem, from `SPKG.txt`:
{{{
To update the autotools[-generated] files, do the following:
cd src/
libtoolize --copy --force
aclocal -I m4
autoconf
autoheader
automake --add-missing --copy
(You'll of course need current versions of m4, libtool, autoconf and
automake to produce files that support/work with LTO. To check this,
it is sufficient to try `CFLAGS="-flto" ./configure && make`; you need
a recent version of GCC supporting LTO as well.)
And don't forget to afterwards remove left-over temporary files:
make distclean
rm -rf autom4te.cache config.h.in~
(I used m4 1.4.16, libtool 2.4.2, autoconf 2.68 and automake 1.11.3
to update the files for the glpk-4.47.p0 spkg.) -leif (03/2012)
