#322 hfst-proc is missing or broken for new installations

[Flammie Pirinen]

From omorfi bug report 14 https://github.com/flammie/omorfi/issues/14:

not sure if related, but for some reason hfst-installation created hfst-proc as a link to a non-existant file. However, then just replaced that link with real 'hfst-proc' from the precompiled binaries.

Before that change, the omorfi configuration stopped to this:

checking for /work/bin/hfst_v383/bin/hfst-split... yes
checking for /work/bin/hfst_v383/bin/hfst-conjunct... yes
checking for /work/bin/hfst_v383/bin/hfst-proc... no
configure: error: HFST commandline tools are needed in /work/bin/hfst_v383/bin
ls -la /work/bin/hfst_v383/bin/hfst-proc
/work/bin/hfst_v383/bin/hfst-proc -> hfst-apertium-proc
ls -la /work/bin/hfst_v383/bin/hfst-apertium-proc
ls: cannot access /work/bin/hfst_v383/bin/hfst-apertium-proc: No such file or directory

and the precompiled version is, which now exists in the hfst-directory

./hfst-proc --version
hfst-proc 0.0 (hfst 3.8.2)

hsft-proc needs to be separately enabled with --enable-proc option to configure.sh. This creates the hsft-apertium-proc which is symlinked.

I ran into this when adding HSFT to Mac Homebrew. The symlink step fails if proc is not built. The problem is that these lines in tools/src/hfst-proc/Makefile.am should be disabled if WANT_PROC is disabled:

cd $(DESTDIR)$(bindir) && \
    $(LN_S) -f hfst-apertium-proc$(EXEEXT) hfst-proc$(EXEEXT)

I don't know Automake well enough so I can't provide a patch.
