The rpath-2* tests are sensitive to
 
34
  - incomplete shared library support in the system,
 
35
  - bugs in libtool that creates the shared libraries,
 
36
  - bugs in lib-link.m4.

The rpath-3* tests are sensitive to
 
39
  - incomplete shared library support in the system,
 
40
  - bugs in libtool that creates the shared libraries.
 
41
 
 
42
Known failures:
 
43
 
 
44
* On all platforms supporting shared libraries,
 
45
    rpath-3aae rpath-3aag
 
46
    rpath-3abe rpath-3abg
 
47
  fail. This is a libtool 1.4.2 bug: When a shared library depends on a
 
48
  static library indirectly through two different dependency paths,
 
49
  libtool attempts to link together invalid sets of object files.
 
50
 
 
51
* OSF/1 4.0: the tests
 
52
    rpath-2bbd
 
53
    rpath-3bbd rpath-3bbf rpath-3bbg rpath-3bbh
 
54
  fail, because -rpath options are not cumulative:
 
55
  The last -rpath option overrides all previous ones. One would need to
 
56
  pass all directories, separated by colons, in a single -rpath option.
 
57
 
 
58
* Solaris: the tests
 
59
    rpath-3bae rpath-3bbe
 
60
    rpath-3aaf rpath-3abf
 
61
    rpath-3baf rpath-3bbf
 
62
  fail, because code from static libraries not compiled with -fPIC cannot
 
63
  be integrated into shared libraries: linker error "Text relocation remains".
 
64
 
 
65
* Cygwin: The tests
 
66
    rpath-2aac rpath-2abc
 
67
    rpath-3aac rpath-3aaf
 
68
    rpath-3abc rpath-3abf
 
69
  fail.
