Created attachment 617958 [details, diff] bcc-0.13.0-clang-10.patch This is an issue with llvm-10, my cmake is not really strong enough to fully fix this, but I have a (very) hacky patch that improves the situation. This does *not* fix it, but it is a starting point if someone else wants to take a look...
The patch below does the job. dev-util/bcc cannot handle all the changes in LLVM 10. The separate libraries have been combined into a single one. If you list your llvm lib directories for 9 and 10 you'll see the change. -- diff --git a/dev-util/bcc/bcc-0.13.0.ebuild b/dev-util/bcc/bcc-0.13.0.ebuild index 8ff7d3262f4..748cd29f46e 100644 --- a/dev-util/bcc/bcc-0.13.0.ebuild +++ b/dev-util/bcc/bcc-0.13.0.ebuild @@ -5,7 +5,7 @@ EAPI=7 PYTHON_COMPAT=( python3_{6,7,8} ) -inherit cmake-utils linux-info python-single-r1 +inherit cmake-utils linux-info llvm python-single-r1 EGIT_COMMIT="v${PV}" LIBBPF_VER="0.0.7" @@ -27,8 +27,8 @@ REQUIRED_USE="${PYTHON_REQUIRED_USE}" RDEPEND=" >=sys-kernel/linux-headers-4.14 >=dev-libs/elfutils-0.166:= - sys-devel/clang:= - >=sys-devel/llvm-3.7.1:=[llvm_targets_BPF(+)] + <sys-devel/clang-10:= + <sys-devel/llvm-10:=[llvm_targets_BPF(+)] luajit?
