Build failure on linux with llvm 3.7.0
Closed this issue · 7 comments

- linux x86_64 4.2.3
- clang/llvm 3.7.0
- gcc 5.2.0
When attempting to set both the C_COMPILER and CXX_COMPILER together, cmake identifies the C compiler as clang but the CXX compiler as gcc. So instead I used the CC and CXX environments instead which appears to have worked. Either way both compilers generate similar errors, formatted in their particular manners.
Note: I am not using a build directory, but this doesn't change the result.

Hi! The reason is that LLPE currently builds against LLVM 3.6. However I have created a 3.7 branch that compiles against 3.7 (but is untested). Could you try
git pull
git checkout 3.7
And then rebuild?

It gets a bit futher before coming upon a new error:

This is a Clang vs. G++ thing (the former doesn't support non-POD VLAs). Either use G++ or I'll finally remove the VLA stuff tonight :)

Ah, I thought given its llvm nature that clang was assumed. It does get further again with gcc (g++) but a new error is produced:

As for removing VLAs, that always sounds like a good idea :-P
smowton commented
Both of these are done -- the one remaining VLA is now a vector, and the TLI include path is fixed (it was finding an old LLVM source tree by mistake).
Unfortunately building with Clang is currently still blocked because WxWidgets uses typeid and LLVM builds with -fno-rtti per default. Odd that GCC is ok with that, but it seems it is! So for now try building with GCC and I'll look into the RTTI issue some more.

That did the trick, it builds to completion now but with many warnings essentially repeating the same thing:
/home/earnest/build/lab/llpe-git/src/llpe/llpe/driver/Integrator.cpp:636:1: warning: ‘virtual void wxWindowBase::MakeModal(bool)’ is deprecated [-Wdeprecated-declarations]

Other than that, this particular issue can probably be closed now.

Standard WX I'm afraid :) Thanks for the report!
