[llvm-dev] Link error on Linux

Since the log tells you that llvm::outs() is not found, and since it is supposed
to be found in libLLVMSupport.a, you can try:

$ nm /home/a/build//lib/libLLVMSupport.a  | grep ZN4llvm4outsEv
...
0000000000002070 T __ZN4llvm4outsEv
...


The output should have the symbol defined.

[llvm-dev] Link error on Linux

Yeah, seems to.

a at a-VirtualBox:~$ nm /home/a/build//lib/libLLVMSupport.a  | grep
ZN4llvm4outsEv
                 U _ZN4llvm4outsEv
                 U _ZN4llvm4outsEv
0000000000000000 b _ZGVZN4llvm4outsEvE1S
0000000000000000 T _ZN4llvm4outsEv
0000000000000000 r _ZZN4llvm4outsEvE19__PRETTY_FUNCTION__
0000000000000000 b _ZZN4llvm4outsEvE1S
                 U _ZN4llvm4outsEv

I can try building with RTTI, it'll just take a few hours to run the build.
