<br>
Here's the outstanding work and my (not necissarily correct) view of the status and importance of each one:<br>
<br>
* Bug 12157 - <a href="http://llvmconfig.cmake.in" target="_blank">llvmconfig.cmake.in</a> make cmake installations not relocatable<br>
- There are patches on the bug that we should review, test, and land<br>
<br>
* Bug 14109 - CMake build for compiler-rt should use just-built clang<br>
- Still waiting for patches, I don't think this is a blocker<br>
<br>
* Bug 15493 - No option to build shared libLLVM-version.so in CMake<br>
- Patches out for review <a href="http://reviews.llvm.org/D6157" target="_blank">http://reviews.llvm.org/D6157</a><br>
<br>
* Bug 18496 - [cmake] .S assembly files not compiled by cmake in libclang_rt.ARCH<br>
- Unclear if this is still a problem<br>
<br>
* Bug 18722 - Option to use CMake with libc++ to compile clang<br>
- I think this is done by passing -DLLVM_ENABLE_LIBCXX=On<br>
<br>
* Bug 19462 - Use the INSTALL(EXPORT ...) to export CMake definitions<br>
- I believe this is all done. I've never managed to get the import part of this to work, but the export files are generated<br>
<br>
* Bug 19875 - libraries and executables need different rpaths<br>
- Still outstanding, I don't think this is a blocker.<br>
<br>
* Bug 21560 - Add support to cmake for using installed versions of LLVM and Clang<br>
- Takumi commented that this works.<br>
<br>
* Bug 21561 - Update release scripts to use CMake<br>
- Still outstanding and blocking removal of autoconf<br>
<br>
* Bug 21562 - Add a CMake equivalent for make/platform/<a href="http://clang_darwin.mk" target="_blank">clang_darwin.mk</a> in compiler_rt<br>
- From discussions on llvm-dev and IRC the proper fix for this is a cross-compiling approach for compiler_rt builds, and this is a blocker.<br>
<br>
* Bug 21568 - Cannot add rpath<br>
- It looks like this is not a blocker because it can be done, but is unwieldy. I think this may be made a lot easier with help from the CMake developers.<br>
<br>
* Bug 21569 - Can't `make install prefix=/tmp/llvm' with CMake.<br>
- I think this is a fundamental difference between CMake and autoconf, and people just need to get used to the difference<br>
<br>
* Bug 21570 - Cannot set default configuration options for CMake<br>
- I think you can do this in CMake by creating a toolchain file and passing it in with CMAKE_TOOLCHAIN_FILE<br>
<br>
<br>
Other issues not tracked by bugs:<br>
<br>
* FreeBSD seemed to have problems with CMake identifying itself as amd64 causing x86_64 tests to fail<br>
* Migrating buildbots<br>
* CMake builds for libc++?<br>
<br>

Thoughts? Anything missing?<br></blockquote><div><br></div><div>One more thing: we should probably update "Getting Started" pages (<a href="http://clang.llvm.org/get_started.html">http://clang.llvm.org/get_started.html</a>, <a href="http://llvm.org/docs/GettingStarted.html#getting-started-quickly-a-summary">http://llvm.org/docs/GettingStarted.html#getting-started-quickly-a-summary</a>) to</div><div>refer to CMake as the "recommended" way to build LLVM, and to autotools as "works for now".</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
