So I'm trying to get back to this, and built -DBUILD_SHARED_LIBS=ON HEAD
llvm/clang, applied your patch to switch from .a to .so and got a smaller perf
binary that is dinamically linked to tons of libraries from LLVM and clang, see
below, how to proceed?
I think we should default to linking it dinamically, which is what I'll have in
a test branch and add some machinery to autodetect and use the right approach,
can you do that while I try to go on processing the next patches?
Its a huge bump in the number of libraries in such a build:
[acme@jouet linux]$ ldd /tmp/perf | wc -l
174
[acme@jouet linux]$ ldd /tmp/perf | egrep -i llvm\|clang | wc -l
145
[acme@jouet linux]$
But one expected by those explicitely enabling support for eBPF, right? Those
needing a llvm/clang toolchain installed can opt for using the external
toolchain, that we keep in place, those with a need for those libraries can use
this approach and then those just wanting perf+eBPF, say on a smartphone, like
you said, can get everything in a static build.
