I'm not sure if I'm understanding the issue. Do you need to locate the lanes.so file? Shouldn't it be possible just to do `require "lanes"` to load/use it? Do you want to call C functions from the lanes.so file directly from your C code? I guess you could access the Lanes API as Lua functions. > 2) I then want to build another module that needs the previous one as a > dependency(but no linking here).

Unfortunately platform-overrides use only the OS detection and not the arch variable, so there's no fully automated way to do that. You could set custom CFLAGS in your configuration files but as of now there's no way to specify per-arch flags in a rockspec using the builtin type. > So far I have been building it with cmake, are these configurations > possible with the builtin type of luarocks? Thank you in advance If the builtin type proves insufficient, you can keep using cmake integrated with LuaRocks. -- Hisham ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
