How to compile. Also, update your compiling environment.

[the bigg]

Windows
For those who have already compiled WeiDU in the past:
OCaml 3.10 was released, it will depend on TK 8.4 rather than TK 8.3. The links bring you to the download pages. Once you've downloaded them, install ocaml in C:\ocaml and TK in the default directory. Delete tk83.dll from your work directory and put there tk84.dll from http://www.activestate.com/store/activetcl.

If you've never compiled WeiDU, instructions are available here.

Debian-based Linux
run as root:

Code:

apt-get install build-essential ocaml-native-compilers tk8.4-dev tk8.3-dev zip unzip upx tetex-extra hevea

I install tk8.3 and 8.4 because Debian Stable and Testing currently don't ship Ocaml 3.10. You can get it from http://ocaml.org if you have 3.09 installed.

After that, unzip some version of WeiDU-Linux and the current source version in the same directory; cd to the WeiDU directory, edit your files, and run `make linux_zip'.

Mac OSX
instructions for compiling are available here.
To update OCaml: run steps 2 to 10 from those instructions.

Just wanted to add that in newer WeiDU versions you will also need Elkhound.
I got the (probably outdated) tarball from the berkeley site.
It refused to compile on my debian box, but I was able to build it after fixing some perl script. (Probably has something to do with a newer flex version.)

I use the berkley.edu version as well.

For me, `./configure && make && sudo cp elkhound/elkhound /usr/bin' worked out of the box.

EDIT: also, yeah, I really should mention elkhound somewhere.

[Taimon]

I used flex 2.5.34.

smbase/run_flex.pl launches flex and modifies the generated file after that. (putting some #ifndef's in)
Unfortunately it deletes some flex-generated end comment (*/) during this modification that.
I just mention it here, so if anyone ever has the same issue, he knows where to look at.

How did you compile elkhound on windows? Cygwin + gcc?
I ended up using cygwin + mingw32, but had to edit another file (ckheap.h).
Cross-compile from linux did not work for some reason. Linker did not recognize the symbols in libsmbase.a. No idea.

Oh, and ocamlopt.opt.exe (3.10.2) did crash on trealparser.ml.
(But ocamlopt.exe works.)

Yup.

Don't get me started on my hate speech against french people, PLZ. Suffice to say, I think that saying "it's a feature, not a bug" should be punishable by death in a modern country.

Link is broken.

[the bigg]

I've lost the file and it isn't on archive.org. Does anyone have a copy?

[Mike1072]

Oh, snap.

Will give it a go tomorrow, I think.

[the bigg]

Doesn't show up if I use the 'resurrect this page' Firefox extension. Guess it's because of /~thebigg/ vs. /users/thebigg/.
That file is outdated, though - it doesn't describe installing elkhound 

[the bigg]

Fixed the broken link, updated with references to elkhound (yes, I'm sure a certain bit in those instructions is TheDailyWTF worthy).

[erik]

Yay. Modern ubuntu has ocaml 3.10.2 packages.

Thanks for updating it.  I think I've managed to compile it successfully.  I had to do a couple things differently, though.

In this section:

- Fix these file errors (in all cases, by closing the comments with a */ like you'd do in .tp2, .d etc.).
      C:\cygwin\home\username\elsa-2005.08.22b\ast\agramlex.yy.cc, line 1229
      C:\cygwin\home\username\elsa-2005.08.22b\ elkhound/gramlex.yy.cc, line 1366
- Once you fixed these files, continue running the following in Cygwin:
    for a in smbase ast elkhound; do cd $a; ./configure; cd ..; done
    for a in smbase ast elkhound; do cd $a; ./make; cd ..; done
    cp elkhound/elkhound.exe /usr/bin

The files with the errors in them didn't exist before make was executed, so I had to do this instead:

cd smbase
./configure
make
cd ../ast
./configure
make
(error gets reported here - need to fix agramlex.yy.cc, line 1229)

Fixed it:

/* The contents of this function are C++ specific, so the () macro is not used.
*/
#ifndef NO_YYFLEXLEXER_METHODS
yyFlexLexer::yyFlexLexer( std::istream* arg_yyin, std::ostream* arg_yyout )
{

Then continued:

make
cd ../elkhound
./configure
make
(error gets reported here - need to fix gramlex.yy.cc, line 1366, do same as above)
make
cp elkhound.exe /usr/bin

Then I felt pretty good, but I ran into an issue when running make windows_zip in the WeiDU directory.  I got some error basically telling me that flexlink didn't exist.  I made sure I'd installed flex, and when I couldn't find anything more, I Googled it and came up with this page.  Grabbing the binary package there made it work.

Now I just need to make the docs...

Edit: Woot, can make docs, too.

By the way, this was my modification to smbase/run-flex.pl to get around the grammar issue:

Code:

--- elsa-2005.08.22b/smbase/run-flex.pl
+++ elsa-2005.08.22b/smbase/run-flex.pl
@@ -220,12 +220,9 @@

   elsif ($state == 6) {
-    if ($line =~ m/^yyFlexLexer::yyFlexLexer/) {
+    if ($lines[$i+1] =~ m/^yyFlexLexer::yyFlexLexer/) {
       $state++;
-      $i++;       # skip the '{' line, to keep #line numbers in sync
-      chomp($line);
-      print OUT ("#ifndef NO_YYFLEXLEXER_METHODS\n" .
-                 $line . " {\n");
+      print OUT ("#ifndef NO_YYFLEXLEXER_METHODS\n");
       next;
     }
   }

(a bit late) uploaded a fixed version of elkhound to the weidu.org host. Taimon, you posted a reversed patch 

[Taimon]

Oh... I knew it looked a bit odd.
