[SOLVED] LLVM and ncursesw

Hola,

I compile Blender from source and have for years. Lately (couple of weeks) I'm getting this error:

Linking CXX executable ../../bin/blender
/usr/bin/ld: /usr/lib/gcc/x86_64-unknown-linux-gnu/4.8.2/../../../../lib/libLLVMSupport.a(Process.o): undefined reference to symbol 'setupterm'
/usr/lib/libncursesw.so.5: error adding symbols: DSO missing from command line

If I run 'llvm-config --ldflags' it returns:

-L/usr/lib  -lz -lpthread -lffi -lcurses -ldl -lm

Shouldn't '-lcursesw' be included here..?

The compilation completes if I disable LLVM in the cmake config, but I'd rather leave it on for OSL support.

Versions:
llvm-3.4-1
ncurses-5.9-6

Any help would be appreciated! Thanks

Re: [SOLVED] LLVM and ncursesw

Hi, I just had the same problem and managed to solve it. Some weeks ago llvm got updated to version 3.4, and the PKGBUILD of Arch's official Blender got adjusted.

Turns out I had to add

-DWITH_LLVM=ON \
-DLLVM_VERSION=3.4 \
-DLLVM_STATIC=OFF

to my cmake command line, rerun cmake and rebuild. I made a new build directory, just to be safe. Works fine.

Hope it helps you also, good luck.
