Building LLDB in swift-4.1-branch on Ubuntu 16.04 fails

scottdensmore · July 2, 2018, 4:38pm

Hi,

I am trying to build swift-lldb from the swift-4.1-branch branch and it is failing. It fails with the following:
CMake Error at cmake/modules/HandleLLVMOptions.cmake:403 (message):
LLVM requires C++11 support but the '-std=c++11' flag isn't supported.
Call Stack (most recent call first):
CMakeLists.txt:593 (include)

Any help appreciated.

The following is the output of the CMakeError.log

What (host) compiler are you building it with?

scottdensmore · July 2, 2018, 4:46pm

clang version 3.8.0-2ubuntu4 (tags/RELEASE_380/final)

I installed this sudo apt install clang. (If I understand your question).

This is the relevant error:

It's not clear to my why CMake checks for -Wungaraded-availablilty. I think it might be easiest for you to just compile with a newer version of clang (or gcc).

scottdensmore · July 2, 2018, 7:36pm

Updated to clang 6

This is the error

clang: error: linker command failed due to signal (use -v to see invocation)

Does the script lldb/scripts/build-swift-cmake.py --test update the dependencies to the correct branches? Do I need to update them myself?

Thanks for the help.

You didn't paste the actual error: What was the linker error clang is complaining about?

That looks more like your linker is running out of memory? On Linux the linker needs to link all the debug information, so it takes a considerable amount of memory. Have you tried with split dwarf or without debug information?

Ok… good to know. It is a VM with only 8gigs of ram. I haven’t tried anything else. I can try giving more ram to the VM and see if it helps.

Good news. Got everything building. I had forgotten to turn my swap file on when I grew the disk.

Should all the tests pass? When I run the command, not all of them pass.

===================
Test Result Summary
===================
Test Methods:       3184
Reruns:               30
Success:            1832
Expected Failure:    181
Failure:              27
Error:                 3
Exceptional Exit:      0
Unexpected Success:   71
Skip:               1070
Timeout:               0
Expected Timeout:      0

Is this expected? At least I can start testing .

Generally, yes, all tests are supposed to pass. Depending on which branch you are building you can check against the results from the official bots on LLDB [Jenkins]. You may have found legitimate bugs, or there is a misconfiguration in your environment or both.

Looking at the swift-4.1 branch build... doesn't look like there was a good build for a while. I'll just assume things are working. Thanks.
