- Assuming that by saying customView, you mean that you have a custom subclass of
- the view class-- in this case, probably a subclass of N3DMovieCamera-- yes,
- this is allowable within a bundle. The source files (whatever.[hm]) should
- just be added to the bundle project like any other source files.
-
- That rld() message is totally useless-- and not uncommon. There is an annoying
- bug in rld such that it doesn't dump a complete message to console. It DOES
- work under gdb-- so you might try attaching gdb to the WM process:
-
- gdb /usr/lib/NextStep/Workspace.app/WM.app/WM
- attach 148
-
- << go inspect a .rib file here and it should give you a useful message >>
-
- In the best case, there is simply some function/class being referenced that you
- have forgotten to include in your code or have mis-typed it (any compiler
- warnings when you compile the code?).
-
- In the worst case, the undefined symbol is N3DCamera itself because WM.app
- doesn't include libMedia-- looking at WM.app/WM via otool -l, one gets:
-
- Load command 6
- cmd LC_LOADFVMLIB
- cmdsize 56
- name /usr/shlib/libIndexing_s.A.shlib (offset 20)
- minor version 1
- header addr 0x0a000000
- Load command 7
- cmd LC_LOADFVMLIB
- cmdsize 52
- name /usr/shlib/libNeXT_s.C.shlib (offset 20)
- minor version 57
- header addr 0x06000000
- Load command 8
- cmd LC_LOADFVMLIB
- cmdsize 48
- name /usr/shlib/libsys_s.B.shlib (offset 20)
- minor version 55
- header addr 0x05000000
- Load command 9
- cmd LC_SYMTAB
- cmdsize 24
- symoff 524288
- nsyms 5106
- stroff 585560
- strsize 121640
-
-
- Which seems to indicate that WM.app doesn't have any kind of a reference to
- libMedia_... which would leave the 3Dkit (and anything else in that lib-- live
- video, as well) inaccessible...
-
- One COULD potentially edit the load commands....
