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:
*** buffer overflow detected ***:

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
