+
+For some experiments with the LLVM just in time (JIT) APIs, I was looking for a
+way to compile in memory from `C -> LLVM IR` and without invoking Clang as a
+child process.
+
+I created a minimal example for my purpose based on the [Clang
+source][src-clang] code and the example given in the blog post [Compiling C++
+Code In Memory With Clang][blog-clang-in-memory].
+
+The code listing below shows the example with detailed comments inlined, hence
+I am not further describing any details here.
+
+> The example was build & tested with LLVM & Clang 13.
+
+```cpp
+{{ include(path="content/2022-06-18-libclang-c-to-llvm-ir/gen-ir.cc") }}
+```
+
+The following Makefile can be used to compile and run the example.
+
+```make
+{{ include(path="content/2022-06-18-libclang-c-to-llvm-ir/Makefile") }}
+```
