[cfe-users] Cannot build Clang etc. on Windows in Debug Mode

2020-07-06 Thread Oliver Niebuhr via cfe-users 
Hello List.

I hope I have subscribed to the correct List - there are a lot of them :)

My Problem is:
Since the last 2.5 Weeks I try to compile Clang Release/10.x in Debug
Mode. Unfortunately the build always ends with those last Lines:

Well it says for "Developers of Clang" but Okay I will try my Luck there

CMake: 3.18.0
Ninja: 1.10
LLVM: 10.0.1 Git Branch

Works with: VS 2019 16.6.5, 16.6.6

Additional Compiler Flags tested: /std:c++17 (which gets overwritten
with /std:c++14 no matter what), /permissive and /permissive-

I looked through the Interweb but did only found 2 old LLVM Bug Reports
for LLVM 7.x which are closed.

Everything points to being an "underwhelming" work around in LLVM.
Therefore: Is this a Problem with LLVM or do I need to Report this to
the VS Team?
Thanks!
Oliver

[cfe-users] Shared Debug Build MSYS2 MinGW-w64 constant Link Error

2021-05-11 Thread Oliver Niebuhr via cfe-users 

Hello.

As Static Debug Builds only work with MSVC, I am forced to use 
Shared-Libs with GCC on MSYS2.


The Problem is, it always Fails at this exact stage:

But that does only partially matter(?), because even with the DEFAULT 
FLAGS IT FAILS at this stage. So it seems I am missing something else. 
Another Compiler Flag? Another Linker Flag? General incompatibility?


Thanks in advance!
