'-DPLUGIN_DIR="/usr/local/share/trace-cmd/plugins"' -DHAVE_UDIS86 -ludis86 -DHAVE_BLK_TC_FLUSH -shared -nostartfiles -o plugin_blk.so plugin_blk.o But when looking, I just noticed that it does not appear in the imports $ ldd plugin_kvm.so linux-vdso.so.1 => (0x00007fff3cfff000) libc.so.6 => /lib64/libc.so.6 (0x00007f6429e1c000) /lib64/ld-linux-x86-64.so.2 (0x00007f642a3e4000) Nor do I actually *have* the .so of udis86 in my /usr/lib directory. Gentoo by default just built the static library. Weird! I'll recompile myself and then it'll work for sure.
