Subject: Making a shared library that intercepts call to main work with musl compiled binary

Hi All,

I've shared library [1] which intercepts loading of a binary and does some
pre-processing with the command-line arguments via "LD_PRELOAD" technique.
The shared library works fine with glibc compiled binary i.e., it can
intercept the call to main and does some preprocessing. But it can't
intercept call to "main" in musl-compiled binary. I've compiled my binary
in static mode with musl "CC=/musl-gcc -static". How can I make the shared
library work with musl-compiled binary?

Thanks
Riyad
