<br class="">
Time for another update on the status of the CMake build system.<br class="">
<br class="">
Completed:<br class="">
* Bug 18496 - [cmake] .S assembly files not compiled by cmake in libclang_rt.ARCH<br class="">
* Bug 22725 - lldb build with cmake fails with "Program error: Invalid parameters entered, -h for help. "<br class="">
* Update GettingStarted to prefer CMake<br class="">
<br class="">
Still Outstanding:<br class="">
<br class="">
* Bug 14109 - CMake build for compiler-rt should use just-built clang<br class="">
- No Update: Still some small issues to resolve.<br class="">
<br class="">
* Bug 19462 - Use the INSTALL(EXPORT ...) to export CMake definitions<br class="">
- I commented in the review for this today (<a href="https://urldefense.proofpoint.com/v2/url?u=http-3A__reviews.llvm.org_D7623&d=AwMFaQ&c=8hUWFZcy2Z-Za5rBPlktOQ&r=Mfk2qtn1LTDThVkh6-oGglNfMADXfJdty4_bhmuhMHA&m=CnMJsu0f0vSR1CHLloYJapdWWCpu9GRn3nQydr1tcoc&s=sUUTJf37gKTcDMx58mdbge8nZhoWhIh5vIfTXTa8ibI&e=" target="_blank" class="">http://reviews.llvm.org/D7623</a>).
I think the patches I have are good to land, but Stephen Kelly made some other suggestions in the bug we should consider separately.<br class="">
<br class="">
* Bug 19875 - libraries and executables need different rpaths<br class="">
- No Update: Still outstanding, I don't think this is a blocker.<br class="">
<br class="">
* Bug 21561 - Update release scripts to use CMake<br class="">
- No Update: Still outstanding and blocking removal of autoconf<br class="">
<br class="">
* Bug 21562 - Add a CMake equivalent for make/platform/<a href="https://urldefense.proofpoint.com/v2/url?u=http-3A__clang-5Fdarwin.mk_&d=AwMFaQ&c=8hUWFZcy2Z-Za5rBPlktOQ&r=Mfk2qtn1LTDThVkh6-oGglNfMADXfJdty4_bhmuhMHA&m=CnMJsu0f0vSR1CHLloYJapdWWCpu9GRn3nQydr1tcoc&s=wt0UGa6r8x3w45AVGzPGHAjLVWguk3nXjPFh74rdxxM&e=" target="_blank" class="">clang_darwin.mk</a>
in compiler_rt<br class="">
- I've looked at this a bit on and off. It is unfortunately a hard problem. I think it would be easier if CMake had better support for setting clang's sysroot and arch flags. To that end I've filed a bug against CMake (<a href="https://urldefense.proofpoint.com/v2/url?u=http-3A__www.cmake.org_Bug_view.php-3Fid-3D15591&d=AwMFaQ&c=8hUWFZcy2Z-Za5rBPlktOQ&r=Mfk2qtn1LTDThVkh6-oGglNfMADXfJdty4_bhmuhMHA&m=CnMJsu0f0vSR1CHLloYJapdWWCpu9GRn3nQydr1tcoc&s=umuCvLy-UFJkds60slnEM9ROl2OiO4qvtQbhF7MhIF8&e=" target="_blank" class="">http://www.cmake.org/Bug/view.php?id=15591</a>).<br class="">
<br class="">
* Bug 21568 - Cannot add rpath<br class="">
- No Update: Not a blocker.<br class="">
<br class="">
Other issues not tracked by bugs:<br class="">
<br class="">
* FreeBSD seemed to have problems with CMake identifying itself as amd64 causing x86_64 tests to fail<br class="">
* Migrating buildbots<br class="">
* We need to make sure libc++ works properly on Darwin<br class="">
* Put together a “cheat sheet” document for transitioning<br class="">
- If you have an autoconf workflow you’d like to see in the cheat sheet please send your commands my way and I‘ll assemble the cheat sheet.<br class="">
<br class="">
If there is anything I’m missing please let me know. Thanks,<br class="">
<br class="">
Thanks,<br class="">
