I'll analyse the failures more, I don't need help at this point (may do later).
Contributor guide
First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start by reproducing the musl build failure and inspect the affected entry points: cmd/bpf_dump.c, include/rtld_db.h, libproc/libproc.h, libdtrace/drti.c, and the listed test/triggers and test/utils files. Determine the compatibility work needed for open64, Lmid_t, and dlmopen, then run the build and testsuite to verify that dtrace-utils builds and its tests execute successfully on musl.
