Dear CMake developers,
I tried to compile CMake against libc++ on OS X 10.7. For a weird
reason it fails:

The weird part is that part of the command is simply "cut off":
CMakeFiles/CMakeLib.dir/cmDependsFortran.cxx.o CMakeFiles/CMak<cut>
I looked into Source/CMakeFiles/CMakeLib.dir/link.txt. The first line
in that file contains 5356 characters, but the line gets cut off at
exactly 1024 when printed on the screen and fails with
ar: CMakeFiles/CMak: No such file or directory
For some reason the command
/path/to/cmake-3.0.0/Bootstrap.cmk/cmake -E cmake_link_script
CMakeFiles/CMakeLib.dir/link.txt --verbose=1
isn't outputting the whole command, but cutting it in the middle instead.
If I execute that command from link.txt manually, it works ok and the
build continues.
It then fails again with
cd /path/to/cmake-3.0.0/Source &&
/path/to/cmake-3.0.0/Bootstrap.cmk/cmake -E cmake_link_script

ld: archive has no table of contents for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Running with a newer compiler says
ld: archive has no table of contents file
'CursesDialog/form/libcmForm.a' for architecture x86_64
That was the file that failed to compile earlier. But it seems that
the compiler made the file (is that a bug?) and CMake didn't know
anything was wrong and assumed the file was fine. The workaround was
to remove that file, compile it manually by running the contents from
CMakeFiles/cmForm.dir/link.txt, run make again, do a few other things
manually following the same procedure (after some commands were cut
after 1024 characters).
And then the build succeeded.
I would be grateful for any hints about how to avoid these problems
with 1024 characters limit.
Thank you,
Mojca
(CMake works ok when it is built against libstdc++ on 10.7 or against
libc++ on 10.9.)
