Hopper compiler error : undefined reference to `__hopper_trace_cmp'

[redcrabs]

I'm building libpng via Docker (To make sure that the install process of hopper is right) .

To build libpng with Hopper clang compiler :

CC=/hopper/install/hopper-clang CXX=/hopper/install/hopper-clang++ ./configure
and
make

But here's part of the error I'm getting :

Any ideas on how to resolve the issue? Is this a known bug in Hopper?

Thanks.

The issue is due to that you want to build a executable instead of binaries solely. Just ignore the errors, and find the library the linking it with hopper's runtime.
