Description
Building xscorch fails to build on Mac OS 10.6. This is the error I saw in the log:
:info:build clang: error: unknown argument: '-fthread-jumps'
Here is a description of the option for GCC 3.4 found here: https://gcc.gnu.org/onlinedocs/gcc-3.4.6/gcc/Optimize-Options.html:
-fthread-jumps Perform optimizations where we check to see if a jump branches to a location where another comparison subsumed by the first is found. If so, the first branch is redirected to either the destination of the second branch or a point immediately following it, depending on whether the condition is known to be true or false. Enabled at levels -O, -O2, -O3, -Os.
I could not find a reference to -fthread-jumps working with clang.
This issue talks about how clang does not recognize a lot of flags (fthread-jumps included): https://github.com/pcsx2/pcsx2/issues/295
My guess is xscorch is meant to be built with GCC instead of Clang.
