I'm currently going through the LLVM OCaml bindings tutorial in preparation for using LLVM in my own project. While the tutorial is very helpful, it was somewhat hard to start due to the fact that I plan on using ocamllex and ocmalyacc and the tutorial hand rolls their own lexer and parser. I have managed to adapt almost all of the tutorial code into using ocamllex and ocamlyacc (the only thing I'm missing is the ability to assign precendence to user defined binary and unary operators), and was wondering if the...

...When I tried it the pre-processor executable had not been created and installed. When the compiler tried to pass it through, it couldn't find anything. It has been a little bit since I tried, and there may have been updates, so the issue may have been fixed. Well you still run into that with ocamllex/ocamlyacc :) Maybe I'm just > used to the stream syntax extension, but I figured it was fair game > since it's part of the standard install.

Attached are alternative the files for chapters 1-7 that use ocamlyacc and ocamllex. I have cleaned them up and debugged them as best I can but I may have missed something, so any comments on them would be great. Also, the LLVM-OCaml bindings are messed up in Fedora 10 (some of the binary files point to their origonal build directory) so I had to put in a dirty hack in the Makef...

Yes! I thought it was a bit of a shame that so much precious LLV...

You may also be interested in this LLVM-based example in OCaml that uses camlp4 for parsing directly: http://groups.google.com/group/fa.caml/msg/5aee553df34548e2 > Secondly, it seems odd to be writing custom parsers > and lexers after tools like Bison and Flex (and ocamllex and ocamlyacc) > have been around for some time.

That was a long time ago and there are probably better alter...

This is something I've been working on: Reworking inspection so it's not a big mess of ad hoc C code, but instead uses a well-defined domain-specific language to describe how we inspect guests. The best introduction to this is the manual page, which I include below (it's also included in patch 2/3). Rich. ---------------------------------------------------------------------- NAME

Previously posted: https://www.redhat.com/archives/libguestfs/2015-December/msg00038.html Inspection now really succeeds on a small number of simple guests. To test it out: $ ./run guestfish -v -x -a /tmp/centos-6.img ><fs> run ><fs> debug sh "guestfs-inspection --verbose" Rich.

This is a more working version. Inspection (partially) succeeds on a real guest this time :-) You can test it out on a real guest (in this case, a CentOS disk image located at /tmp/centos-6.img) by doing: $ ./run guestfish -v -x -a /tmp/centos-6.img ><fs> run ><fs> debug sh "guestfs-inspection --verbose" which will print lots of debugging, and at the end the
