...anything that has been updated - we have a standard install root called "common" that lives one directory up from the build directory on our build machines. The tricky thing I'm running into is that all of the makefiles generated by cmake contain absolute paths, e.g., "/home/dlobron/build/clangport/akamai/llvm/llvm-3.7/llvm/include/llvm" I was wondering if it's possible to build llvm in such a way that all of these files contain relative paths. It would be perfect for me if the above line, and all other generated makefile paths, would read like this: "../comm...

...ke build -- cmake generates its own build files from CMakeLists.txt and runs those instead. Having the compiler-rt source in projects/compiler-rt should be enough to have its functionality built into clang when building with cmake. > > -Alex > >> On Sep 29, 2015, at 11:43 AM, David Lobron via llvm-dev <llvm-dev at lists.llvm.org> wrote: >> >> Hi All, >> >> I need to build clang/llvm from source on an Ubuntu Linux system, in order to build the gnustep Objective-C environment.

> Unfortunately you’ll need to either modify the LLVM build system to build it, or you’ll need to build it yourself by hand. We don’t currently support building the blocks runtime. Thanks! I'm working on a modified build now. Out of curiosity: is cmake still the preferred way to build on Linux? You mentioned that the doc is out-of-date, so I thought perhaps there might be a newer way to

Hi Chris and Alex, Many thanks for these replies. > I dug a little deeper into the history here. It looks like the blocks runtime hasn’t built in the CMake build system in a long time, and I don’t think it has ever been supported in the autoconf system. > > Support for building it with CMake was removed in April 2012 along with the old CMake build system (r154059) because it was

...d be, e.g., /home/USERNAME/build/common/ So for example, clang would be installed to /home/USERNAME/build/common/bin. When I did my initial build, I set -DCMAKE_INSTALL_PREFIX to the "common" path above, but the Makefiles and cmake_makefiles that were generated have a full path (/home/dlobron/build/common), which of course is not portable to other users if they were to do a "make install". Is it possible to set DCMAKE_INSTALL_PREFIX (or another variable) such that I could package my install directory and another user could use it to install to their /home/OTHER-USERNAME/build...
