(noob) svn update of nested projectsquestion

Clang Frontend

Working on the code from trunk in SVN it seems difficult to update all the nested projects at the same time.

The http://clang.llvm.org/get_started.html recommends using “make update” in the (checked out) llvm directory but that fails

{tim@arkham:~/Source/llvm-trunk/llvm} make update
Makefile:44: Makefile.config: No such file or directory
Makefile:151: /Makefile.rules: No such file or directory
make: *** No rule to make target ‘/Makefile.rules’. Stop.
{tim@arkham:~/Source/llvm-trunk/llvm}

(the whole section on this page entitled “Simultaneously Building Clang and LLVM” appears to be out out date, P.C. (Pre Cmake). I wrote the obvious script to to a full update, after build failures due to svn operator error, but I’m guessing there might be a better way.

Best,

Hi Tim,

Working on the code from trunk in SVN it seems difficult to update all the
nested projects at the same time.

The Clang - Getting Started recommends using "make update" in
the (checked out) llvm directory but that fails

You seem to have misunderstood.

"make update" works from the build directory, after you ran configure.
The following is my setup, which works (for me):

~/LLVM/llvm - contains the checked-out LLVM; with clang, compiler-rt inside it
~/LLVM/build - is where the build happens

So, after the checkout procedure

cd ~/LLVM/build
../configure --enable-assertions
make update

{tim@arkham:~/Source/llvm-trunk/llvm} make update
Makefile:44: Makefile.config: No such file or directory
Makefile:151: /Makefile.rules: No such file or directory
make: *** No rule to make target '/Makefile.rules'. Stop.
{tim@arkham:~/Source/llvm-trunk/llvm}

(the whole section on this page entitled "Simultaneously Building Clang and
LLVM" appears to be out out date, P.C. (Pre Cmake). I wrote the obvious
script to to a full update, after build failures due to svn operator error,
but I'm guessing there might be a better way.

Unfortunately, the LLVM project is moving away from autoconf, towards CMake
(unfortunate for me, because the "update" target has not been ported
and I dislike CMake anyway)
