That enables an special implementation that checks for common memory errors and will save us from a lot pain. --- test/test_bins.sh | 2 ++ test/test_flac.sh | 2 ++ test/test_grabbag.sh | 2 ++ test/test_libFLAC++.sh | 2 ++ test/test_libFLAC.sh | 3 +++ test/test_metaflac.sh | 2 ++ test/test_seeking.sh | 2 ++ test/test_streams.sh | 2 ++ 8 files

I've just uploaded the development version 1.11.12: http://download.libguestfs.org/nbdkit/1.11-development/ Please try it out because it's hopefully close to the next stable release, 1.12. Below are some preliminary release notes. If there's anything else that I've missed and should go into this version then let me know. Rich.

Overwriting LD_LIBRARY_PATH broke some tests when running with fakeroot. --- align/Makefile.am | 2 +- cat/Makefile.am | 2 +- clone/Makefile.am | 2 +- df/Makefile.am | 2 +- edit/Makefile.am | 2 +- fish/Makefile.am | 2 +- haskell/Makefile.am | 2 +- ocaml/Makefile.am |

This takes advantage of glibc's MALLOC_PERTURB_. If you develop on glibc-based systems and don't yet set this via your shell's init scripts, add something like this to e.g., .bashrc: export MALLOC_PERTURB_=$(($RANDOM % 255 + 1)) This change ensures that it's enabled for anyone running "make check" and in particular for koji. There's probably documentation

Here are some of the patches that I have maintained in the patch queue of my packages that I maintain within the Debian distribution (http://packages.qa.debian.org/libg/libguestfs.html). All of them address FTBFS (fail to build from source) errors that happened with the particular configuration that is used for building the Debian package. Cheers, -Hilko

Erik, I was thinking of doing this: export MALLOC_PERTURB_=$(awk 'BEGIN { srand(); print int(rand() * 32767 % 255 + 1) }') Or would you prefer using 'date'?

These changes allow virt-v2v to be compiled against the build directory of a non-installed libguestfs. Note that some small changes are also required to common and virt-v2v itself. I will post those separately. Rich.

You have to use: ../libguestfs/run ./configure ../libguestfs/run make Use of the second ../libguestfs/run against make is unfortunate but I believe it's unavoidable due to the way that ocamlfind works. --- .gitignore | 1 + ocaml/Makefile.am | 19 ++++++++++++++++++- run.in | 2 ++ 3 files changed, 21 insertions(+), 1 deletion(-) diff --git a/.gitignore b/.gitignore

Your's is probably better and this is probably an improvement: awk 'BEGIN { srand(); print int(rand() * 255 + 1) }' Awk's rand seems to be

We use a similar trick to libvirt to allow external C programs that use libguestfs to be compiled against the built (but not installed) libguestfs with: ../libguestfs/run ./configure make What actually happens is we have a second pkg-config file (lib/local/libguestfs.pc) which points to the locally built libguestfs. The ./run script sets up PKG_CONFIG_PATH to point to this directory.

We use a similar trick to libvirt and libguestfs to allow external C programs that use libnbd to be compiled against the built (but not installed) libnbd with: ../libnbd/run ./configure make What actually happens is we have a second pkg-config file (lib/local/libnbd.pc) which points to the locally built libnbd.

I’m pleased to announce the next stable release of nbdkit. This release concentrates on numerous feature enhancements - see the release notes below. NBD — Network Block Device — is a protocol for accessing Block Devices (hard disks and disk-like things) over a Network. nbdkit is a toolkit for creating NBD servers. The key features are: * Multithreaded NBD server written in C with good

This also defines SOEXT as the extension of shared objects (ie. "so" or "dll"), and uses it everywhere. I assumed this must already be defined by either autoconf or mingw (like OBJEXT) but I cannot find anything except in glib (G_MODULE_SUFFIX).
