Hi all,
I finally managed to compile pocl and pass all the test.
I think other people might have the same problem, so I wrote down what I
did:
1. I had to patch "lib/Target/HSAIL/BRIGAsmPrinter/BRIGAsmPrinter.cpp" at
LLVM HSAIL Stable 3.7. The patch file provided by POCL is incomplete;
2. I added -fPIC as an extract flag to compile libhsail.a and libncurses.a
3. I configured POCL as
../configure --with-hsa-runtime-dir=[PATH_TO_LLVM_HSAIL]/bin/llvm-config
HSAILASM=[PATH_TO_HSAILasm]/HSAILasm --disable-icd
4. I had to add libhsail.a and libncurses.a into libpocl_la_LIBADD at
build/lib/CL/Makefile (I don't know why the pocl configuration tool does
not add them to the makefile).
