Hi folks,
Im running into some issues trying to compile ispc on a linux machine.
the ispc build process goes nicely up until:
...
Compiling objs/lex.cpp
Creating ispc executable
objs/module.o: In function `Module::execPreprocessor(char const*, llvm::raw_string_ostream*) const':
module.cpp:(.text+0xc36): undefined reference to `llvm::sys::getDefaultTargetTriple()'
objs/ctx.o: In function `FunctionEmitContext::BroadcastValue(llvm::Value*, llvm::Type*, char const*)':
ctx.cpp:(.text+0x71b6): undefined reference to `llvm::Twine::str() const'
objs/ispc.o: In function `Target::GetTripleString() const':
ispc.cpp:(.text+0x2211): undefined reference to `llvm::sys::getDefaultTargetTriple()'

objs/opt.o:opt.cpp:(.text+0x1dd7): more undefined references to `llvm::Intrinsic::getName(llvm::Intrinsic::ID, llvm::ArrayRef<llvm::Type*>)' follow
clang-3.8: error: linker command failed with exit code 1 (use -v to see invocation)
Makefile:264: recipe for target 'ispc' failed
Ive tried this using the llvm/clang build with the alloy.py script, Ive tried with the binary versions apt-get installs. Ive build llvm/clang from the tarballs
all give the same result. All are 3.8 versions if it matters. and version 5 of gcc which might matter more then anything. I have Intel compilers on the machine
but they fail in the build process way earlier.
thoughts/suggestions?
thanks

Hi,
Alloy.py build should work, but not sure about other options. Just to make sure - have you checked that you correctly added clang built by alloy.py to your path? I.e, "which clang" points to newly built clang.

I do get the clang (and llvm) that is built with the alloy.py script.
even trying older versions of llvm/clang/ispc result in the end with the same error.
At the moment I using a build script that has worked for other, its using a really
old 3.6.2 version of llvm and the latest ispc. will see how that goes.

That's weird. Can you run check_env.py and copy its output here?
I was going to build a docker image with ispc build environment (including clang), this may probably help debugging your issue. I think I'll build it over the weekend.

Everything looks perfectly correct. And your ispc sources are based on fresh https://github.com/ispc/ispc.git, right?

fyi with the release of 1.9, I grabbed the 1.9.1 tree (using git https://github.com/ispc/ispc.git returns 1.9.2dev btw)
still had the same problem, as did 1.9.2dev. When I picked llvm version 3.8.
if I use alloy.py --version=trunk both 1.9 versions compile fine.
1.8.X fails on trying to build llvm with the trunk option.
so Im good at this point. you might want to update what make in the ispc directory returns when
llvm_home is defined not appropriately.
thanks

I've reproduced the problem.
It comes from some incompatibility of clang (which is used by default to build ispc) and gcc (which is used to build the clang itself). To fix the problem you have to either build clang with clang (basically add --selfbuild to alloy.py command line) or build ispc with gcc (i.e. run "make gcc", not just "make"). This is something new, it used to work well.

Do I understand it correctly that it's the GCC 5 ABI Tag issue?
If so, using Clang 3.9 should also work, right?
Also, is the SKX patch for LLVM 3.8 still applicable to 3.9?
Cheers,
Aristid

Not sure if this is gcc 5 ABI Tag issue, but it's definetly some kind of ABI incompatibility between gcc and clang. So if you see this issue - either use clang self build or use gcc for ispc build.
SKX patch is not need for 3.9, it was back ported from 3.9.
