JoCaml on Windows NT

Here are simple instructions to get started:

• Get the latest Cygwin Net release at http://www.cygwin.com/ and install it.
• Get the latest version of Jocaml at http://moscova.inria.fr/jocaml/, and extract it. To this end, use the tar tool provided by cygwin, since other tools may omit to extract empty directories needed for the compilation.
• in the jocaml directory, type
  • ./configure
  • make world
  • make bootstrap
  • make opt
  • make install

How about graphics:
You simply need to install some X server and X include files before doing the ./configure.

  Tiny FAQ:

• make world does not terminate when compiling num, or terminates with an error vfork: No more processes. Check if there is a directory named otherlibs/num/bignum/o. If it does not exist, either create it, or extract jocaml from the tar compressed file using tar.
• make install does not do anything. Look if there is a file named "INSTALL". If so, rename it in "INSTALL.txt" for instance. (This problem seems to arise because the Windows file system does not make the difference between "install" and "INSTALL").
• I get a "Program too big to fit in memory" error. Do you have the bin directory where jocrun was installed in your PATH ?
• I get a "Thread deadlock" when I try to do anything (typically hitting "return" in the toplevel). Do you have a recent version of Cygwin installed ? This error used to occur with Cygwin B20, but does not anymore with the newest version of Cygwin.
• I get a "Fatal error: cannot open pervasives.cmi". If you did not install the jocaml libraries in their default directory (eg if you specified a different installation path for the "./configure"), you need to set the "JOCAMLLIB" environment variable to the directory where the jocaml libraries are installed. To do this, simply type: export JOCAMLLIB=/usr/local/lib/jocaml with the library directory instead of /usr/local/lib/jocaml.
