Hello,

I loaded "LEDA-R-3.2.3" library, and I compiled it. I noted all the
potential problems and reported them here. It may help other users.

I compiled LEDA on a Sun SPARCstation 20.
The operating system was Solaris 2.4 (SunOS 5.4) with patch 101945-13.
The compiler used was gcc version 2.7.0.

By the way, I succeeded to compile LEDA as shared library, it is
not so difficult.  Without the sharing libraries, compiling all the
programmes with `-g -O' requires more than 100 MB ! More in another
post.

--------------------------
1) Compilation of the libraries: OK !

  Only one problem happened. I compiled the library with both options
  "-g" (debugging) and "-O" (optimisation). (Yes, I had to change the
  Makefile ! ). "_mw_mat1.c" and "_mw_mat2.c" do not support both
  options; I had to compile them without "-g". It is propably an
  overflow in gcc-2.7.0, the generated assembly source is more than 2
  MB !
  -------------
  ../../c++  -I../../incl -g -O -DLEDA_CHECKING_OFF -c _mw_mat1.c
  cc1plus: /var/tmp/cca001DQ.s: I/O error
  make[2]: [_mw_mat1.o] Error 1 (ignored)
  ../../c++  -I../../incl -g -O -DLEDA_CHECKING_OFF -c _mw_mat2.c
  cc1plus: /var/tmp/cca001DT.s: I/O error
  make[2]: [_mw_mat2.o] Error 1 (ignored)
  -------------

  To compile with more than one option, insert lines like these in
  LEDA-3.2.3/makefile: 

  -------------
  lib_gO: 
	cd src;  $(MAKE) -i FLAGS="\"-g -O\""


  pro_gO:
	cd prog; $(MAKE) -i FLAGS="\"-g -O\""

  -------------

2) Compilation of the programmes:

  2.1) The `prog/graph/short' programme calls an algorithm
       "STATIC_DIJKSTA" wich does not exist, compilation crashes.
  2.2) The `prog/graph/shorttest' programme #includes <LEDA/node_slist.h>, 
       which does not exist, compilation crashes.
  2.3) The programmes linked with `-lX11' needs to be linked with
       `-lsocket' on Solaris 2.x. Here is a typical error message:

    -------------
    ../../c++ -g -O -o bin_tree bin_tree.o ../../libP.a ../../libG.a ../../libL.a ../../libWx.a -lX11 -lm
    Undefined			first referenced
     symbol  			    in file

    connect                             /usr/X11R5/lib/libX11.so
    ld: fatal: Symbol referencing errors. No output written to bin_tree
    make[2]: [bin_tree] Error 1 (ignored)
    -------------

        The Makefiles in the directories "prog/windows" and
        "prog/demo" should be updated with the following patch:

3) Documentation:
  3.1) The documentation may not be extracted without `gawk', because
       the awk scripts seems non-standard.
       The following patch for LEDA-3.2.3/man/extman.awk permits to
       use `nawk' instead. Put a symbolic link "LEDA-3.2.3/man/Awk"
       toward either `gawk' if you have it or `nawk'.

  3.2) Adding a "SHELL= /bin/csh" line on top of "man/Makefile" may help.
  3.3) LaTeX errors :
         \abs : Undefined control sequence (extract/graph.tex, l.9,
                   l.10, l.45, l.50)
         Missing $ inserted. (extract/node_list.tex l.1)
       Solutions :
       Put a line "\def\abs {|}" in MANUAL.mac.
       Replace "node\\_list" by "node\_list" on line 1 of
                                       man/extract/node_list.tex.
       Replace "graph\\_misc" by "graph\_misc" on line 1 of
                                       man/extract/graph_misc.tex.
       It should probably be better to update the original .h files.

4) Programmes:
  4.1) `hash_dic' crashes with "Segmentation fault".
  4.2) `bin_tree' crashes with "Segmentation fault".
  4.3) `embedding' gives a message 
         "ERROR(2): sorry: can only embed bidirected graphs."
       with the default settings (random input = on, # segments = 40,
       node width = 12, edge width = 1)
  4.4) `hilbert' stops with "Segmentation fault".
