This seems like a llvm-tv bug, but couldn't submit it as llvm.org is down:
llvm: Compiling CFGGraphDrawer.cpp for Debug build
In file included from CFGGraphDrawer.cpp:2:
TVTreeItem.h: In member function `virtual std::string
TVTreeItem.h:66: error: conversion from `const wxChar*' to non-scalar type `
make: *** [/storage/llvm-src/llvm/projects/llvm-tv/tools/llvm-tv/Debug/CFGGraphDrawer.o] Error 1
make: Leaving directory `/storage/llvm-src/llvm/projects/llvm-tv/tools/llvm-tv'
make: *** [llvm-tv/.makeall] Error 2
make: Leaving directory `/storage/llvm-src/llvm/projects/llvm-tv/tools'
make: *** [all] Error 1
wx-config --version says: 2.5.3
Another thing related to llvm-tv:
it seems it's missing Makefile.common.in. I used suitably modified sample Makefile.common.in.
