Calypso won't link after ldc-0.16.1 update about calypso

[Syniurge]

Hi Kelly,

The first error means that it's linking Calypso built in Debug mode against Release LLVM. It's weird that it got past the cmake call which should have detected this..

Currently building Calypso in release mode against my system's LLVM 3.6 to see if it happens to me as well.

[Syniurge]

It works for me, and if I try to build Calypso in Debug mode while LLVM is in Release mode cmake tells me that it's not possible.

Could you go in build/deps/clang and check if cmake is using the correct LLVM setup with cmake -L?

I have tried to build 'six ways to Sunday' and I just can't get things working here in Debug, Release or RelWithDebInfo mode! Same problems with undefined refs. Here is my 'cmake -L' info:

That's very weird. Could you check the failing ld call arguments with make VERBOSE=1?

The llvm::coverage symbols should be in libLLVMProfileData (regardless of CMAKE_BUILD_TYPE) which is being linked so I don't get it..

[Syniurge]

Kelly could you check /usr/local/bin/llvm-config --version? llvm::coverage::CounterExpressionBuilder appeared in LLVM 3.6, it wasn't in 3.5.

[wilsonk]

Hey Elie,

Yeah, I checked llvm-config --version long ago and it is version 3.6.2. I tried linking with g++ and I still get the same dozens (or hundreds really) of undefined references. I don't get it.

[Syniurge]

ld --verbose tells where it's getting the libs, and clang++ --verbose provides the ld call arguments.

Could you check if ld is selecting the right LLVM libs on your system?

[wilsonk]

Everything looks fine with the ld call. llvm-config --version is 3.6.2 and it is in /usr/local/bin. The LLVM libs are in /usr/local/lib and they are all 'succeeding', the libclang libs are being 'successfully' picked?!?!? I don't get it and I am getting extremely frustrated, unfortunately.

The only failures I see are when looking for libpthread in some directories before it finally finds the right dir...this makes no sense!!!!

[wilsonk]

Looks like this has been fixed now Elie. I just built a new Calypso today and things built fine since the ldc-0.17.1 update.

[Syniurge]

Hi Kelly, glad to hear it's gone and to see you back!
