[Qemu-devel] [Bug 955379] Re: cmake hangs with qemu-arm-static

I have found several places cmake may hang, with either qemu-arm-static
or mipsel, and in debian (testing) as well as in Ubuntu.  One of them is
the cmake check for c++ compiler, which can be overridden.  Things that
use cmake's pkg_check_modules and pkg-config files will also hang.
Curiously, outside of cmake, equivs also will similarly hang if used.
All these things can make it very difficult to use qemu user static
driven chroot's or qemu pbuilder for pkg building at present.

Title:
  cmake hangs with qemu-arm-static

Status in QEMU:
  New

Bug description:
  I'm using git commit 3e7ecd976b06f... configured with --target-list
  =arm-linux-user --static in a chroot environment to compile some
  things. I ran into this problem with both pcl and opencv-2.3.1. cmake
  consistently freezes at some point during its execution, though in a
  different spot each time, usually during a step when it's searching
  for some libraries. For instance, pcl most commonly stops after:

  [snip]
  -- Boost version: 1.46.1
  -- Found the following Boost libraries:
  --   system
  --   filesystem
  --   thread
  --   date_time
  -- checking for module 'eigen3'
  --   found eigen3, version 3.0.1

  which is perplexing because it freezes after finding what it wants,
  not during the search. When it does get past that point, it does so
  almost immediately but freezes somewhere else.

  I'm using 64-bit Ubuntu 11.10 with kernel release 3.0.0-16-generic
  with an Intel i5.
