@bjia56 Do you have any idea why linking to musl libcurl-impersonate failed? I have verified that the curl-impersonate binary works.

Here is the failed build.

/usr/lib/gcc/x86_64-alpine-linux-musl/9.3.0/../../../../x86_64-alpine-linux-musl/bin/ld: /root/.local/lib/libz.a(zutil.o): relocation R_X86_64_PC32 against symbol `z_errmsg' can not be used when making a shared object; recompile with -fPIC
/usr/lib/gcc/x86_64-alpine-linux-musl/9.3.0/../../../../x86_64-alpine-linux-musl/bin/ld: final link failed: bad value

It looks like Zig may have built the archives statically. Can you try adding the -fPIC flag to the Zig flags list? Alternatively, see if libcurl-impersonate.so is usable instead?

[perklet]

Added -fPIC, the x86_64 whl works, however the aarch64 one does not work, weird.

Seems like the compiler is not including certain symbols when building the wrapper so. I found this, perhaps see if it helps? rust-lang/git2-rs#706 (comment)

Dynamic linking works, cheers!
