Hello, I had the problem reporte4d in gentoo bug 792312: dev-util/bcc-0.20.0 - /.../btf.h: error: BTF_KIND_FLOAT undeclared (first use in this function) Aftzer that bug got fixed, I now have the sape problem with dev-util/bcc-0.19.0. :-( The problem with dev-util/bcc-0.20.0 was due to an incompatible API change in libbpf-0.4.0 and the cure was to force bcc-0.20.0 to use libbpf-0.3. Instead of down-grading libbpf to version 0.3, emerge tries to down-grade bcc on my system from 0.20.0 to 0.19.0, but compiling version 0.19.0 fails for the same reason: C707 /home/mkl # emerge --ask --update --newuse --deep @world -j 4 These are the packages that would be merged, in order: Calculating dependencies... done!

I managed to fix my emerge problem by unmerging libbpf and bcc followed by emerge --update. It picked the oder version of libbpf.
