| 33 | 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. |

|---|
| 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. |

| 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. |
