Comment (by ken@…):
The debian patches are, at least partially, applied in 1.16. Long story
short - if I install rustc and one lib (librustc_driver-*.so : initially
ldd said that was not found), and run ldconfig, ldd shows that lib is now
found and all the others are missing (I renamed the DESTDIR to be
absolutely certain).
I ran the tests after that - the jemalloc test appears to not be run, but
I now get 104 failures from all of the gdb tests (because gdb is not
present).
I suppose that means gdb is needed for the testsuite.
This was using rustbuild, but with configure and using *static* llvm
(because rust loves static libs, and things might break in future versions
of either rust or LLVM). For that, I needed a sed from fedora to ensure
-lffi is picked up when system LLVM (built against libffi) is used: there
have been alternative fixes, apparently they no longer work (the shipped
LLVM is not built against libffi). :
{{{
sed -i -e '$a #[link(name = "ffi")] extern {}' src/librustc_llvm/lib.rs
}}}
and then
{{{
./configure --prefix=/usr --llvm-root=/usr
./x.py build
DESTDIR=/some/path ./x.py dist --install
./x.py test
}}}
The tests can be run after the build, but I was more concerned about the
DESTDIR.
Without the tests, build tree was 1.6G, install 264M. The tests added 0.3G
to the build tree.
This was cleaner than previously: I ran each command | tee somelog : the
output on the term showed which file was being built, no need to force
verbosity. It takes all the cores, of course. When I did get an error
(one was local, second eventually led me to the sed) the output did
eventually show the error - 'eventually' because the first time it took
about 3 minutes waiting for other jobs to stop, with 1 core at 100%, and
then it stopped and reported the detail.
No idea how much of it used cmake - I suspect that only really gets used
if building the shipped LLVM. That will be my next step, along with trying
to stop it installing for other architectures, and using a versioned
docdir.
The docs are in /usr/share/doc/rust (unversioned).
