Don't waste your time with 4.8.2 when 4.12.3 is in tree. Does 4.12.3 build fine?

i tried now to emerge qt-creator unstable, which was 4.10.x, cause i dont want to install dozens of unstable qt 5.15 packages which are required for 4.12.3 as you mentioned. 4.10.x stops compiling due to llvm-8.0.1 error.

now i just removed qt-creator...emerge -C qt-creator
Comment 5 Andreas Sturmlechner gentoo-dev 2020-06-29 20:21:41 UTC 
But GCC-10 is not stable either.
Comment 6 Andreas Sturmlechner gentoo-dev 2020-06-30 06:41:25 UTC 
...and llvm-10 is not stable as well, but the build is picking it up in your case, and this is the real issue:

> LLVM_INSTALL_DIR=/usr/lib/llvm/10

You can disable USE=qmldesigner in order to drop the Qt-5.15 dependency.
