[gccsdk] Compiler error trying to build SwiftShader for RISC OS

I was just having a quick go at attempting to see if I could build SwiftShader for RISC OS from it's git repository at:

https://swiftshader/googlesource.com/SwiftShader

 

and it crashed early on with:

See <http://gccsdk.riscos.info/> for instructions.

CMakeFiles/llvm.dir/build.make:86: recipe for target 'CMakeFiles/llvm.dir/third_party/LLVM/lib/Analysis/AliasSetTracker.cpp.o' failed

 

I created a build directory in my swiftshader directory and ran cmake in it as follows:

cmake -DCMAKE_TOOLCHAIN_FILE=~/gccsdk/env/toolchain-riscos.cmake -DBINARY_SUFFIX=,e1f ..

 

I then attempted to build it with:

~/gccsdk/env/ro-make

 

I'm just looking at this out of curiosity, but wondered if this was a real bug or if I had done something wrong.

 

Any ideas?

 

Regards,

Alan
