On my Debian systems, /etc/ld.so.conf.d/libc.conf contains a single line, /usr/local/lib -- this means that the dynamic linker will look there (among other places) for shared libraries. If the library is installed by hand, one still needs to run ldconfig (as root), though because it uses some sort of caching mechanism. The library packages built for Debian make sure that ldconfig is run automatically on installation. Cheers, -Hilko

NB: automake 1.13 miscompiles ocaml/Makefile.am
by Richard W.M. Jones 18 Jan '13

18 Jan '13

If you rebuild the Makefiles using automake >= 1.13 then you'll likely hit this error: Makefile:1904: *** unterminated variable reference. Stop. This is caused by automake miscompiling GNU make macros that appear in the 'TESTS' variable decl in 'ocaml/Makefile.am'. I posted a bug about this upstream. It hasn't appeared yet, but it should turn up here in the near future: http://lists.gnu.org/archive/html/bug-automake/2013-01/threads.html I'm still trying to see if there is a workaround we can add to libguestfs.

A few patches needed for libguestfs 1.20+ on current Debian systems
by Hilko Bengen 18 Jan '13

18 Jan '13

Here's what I needed to build and run 1.20 on Debian/unstable. Perhaps the libcap2 dependency in the packagelist should only be added if libcap has actually been used in building guestfsd...

error make guestfs: relocation libfuse.a Bad value
by Skippy VonDrake 17 Jan '13

17 Jan '13

Trying to setup guestfs on a coworkers system and am at a loss about this error and doing 'make' on version 1.20: /usr/bin/ld: /usr/lib/libfuse.a(fuse.o): relocation R_X86_64_32 against `.bss' can not be used when making a shared object; recompile with -fPIC /usr/lib/libfuse.a: could not read symbols: Bad value collect2: error: ld returned 1 exit status Installed fuse via: sudo apt-get install fuse sudo apt-get install libfuse-dev Tried this before configure: export CFLAGS="-fPIC" And ./configure --enable-shared With and without "--enable-shared". Never had this problem with my system... Any suggestions?

rb_alloc_func_t undeclared in ruby 1.8
by Olaf Hering 17 Jan '13

17 Jan '13

ruby bindings fail to build with ruby 1.8.7 because rb_alloc_func_t does not exist in this version of ruby. This happens due to commit 448a02373df95dafc0d4b3e4db0e77c96a09074d Olaf
