Hello-World

Build and run Hello World in C with a repo-based musl-libc library.

Build musl-libc with the Program Repository Compiler

Create the llvm-prepo container via:

docker pull paulhuggett/llvm-prepo:latest
docker run --rm --tty --interactive paulhuggett/llvm-prepo:latest

Use the following series of commands to install various third-party tools on which the build depends.

sudo apt-get update
sudo apt-get install --no-install-recommends -y ca-certificates git python

Clone the musl-prepo project via:

cd ~
git clone --depth=1 https://github.com/MaggieYingYi/musl-prepo.git

Configure via:

cd musl-prepo
./configure --disable-shared --prefix=~/musl

Perform the build of musl-prepo.

make

Install the musl-prepo.

make install

Build LLVM runtime libraries using the built musl-prepo libc libraries.

Clone the llvm-project-prepo project via:

cd  ~
git clone --depth=1  https://github.com/SNSystems/llvm-project-prepo.git

Clone the pstore project via:

cd llvm-project-prepo
git clone --depth=1 https://github.com/SNSystems/pstore.git

Configure and build clang/LLVM. llvm-config is required when build the compiler-rt library and clang include headers are required when build the libcxxabi library:

mkdir build && cd build
cmake -D CMAKE_BUILD_TYPE=Release \
      -D LLVM_ENABLE_PROJECTS="clang;pstore" \
      -D LLVM_TARGETS_TO_BUILD=X86 \
      -D LLVM_TOOL_CLANG_TOOLS_EXTRA_BUILD=Off \
      ../llvm
make -j 8

Build LLVM runtime libraries via:

cd  ~/llvm-project-prepo/llvm/utils/repo
make all

Build Helloc World with the Program Repository Compiler and musl-libc

Clone the Hello-World project via:

cd ~
git clone --depth=1 https://github.com/MaggieYingYi/Hello-World.git

Build and run hello world C/C++ code.

cd Hello-World
make all
./helloc
./hellocpp
