No, it does not work. Have you tried the example that Kevin linked to?
wget -O clang-standalone-parser.c "http://quickgit.kde.org/?p=kdev-clang.git&a=blob&h=dbad9e8942cc5e20fd005677fc32a5a0b54977ae&f=tests%2Fclang-standalone-parser.c&o=plain"
clang clang-standalone-parser.c -I/usr/include/clang-c -l clang -o clang-
standalone-parser
echo "auto i = 1;" > test.cpp
./clang-standalone-parser --std=c++11 test.cpp
Gives me:
test.cpp:1:6 (5, 0-10) kind: VarDecl type: auto display name: i usr: c:@i
definition
test.cpp:1:10 (9, 9-10) kind: IntegerLiteral type: int
If I add something like this to the standalone example:
printString("type.kind", clang_getTypeKindSpelling(type.kind));
I see: "type.kind: Unexposed" - your assertion fails.
Thanks
