This repository hosts the binaries of the pre-built cross-compiler toolchain
for developing the Pintos projects. The binaries are prefixed with
i386-elf-*, e.g., i386-elf-gcc, i386-elf-ld. The release contains
binaries for two platforms: Linux and macOS. You should download the
appropriate ones.
To use the pre-built binaries (using macOS),
mkdir -p ~/os/toolchain
cd ~/os/toolchain
wget https://github.com/jhu-cs318/cross-compiler-toolchain/releases/download/v1.0/macos-toolchain-binaries.tar.gz
tar xzvf macos-toolchain-binaries.tar.gz
(You can replace ~/os/toolchain with any path you prefer. It is the SWD variable in
the project setup guide)
Test if the toolchain works:
cd ~/os/toolchain/x86_64/bin
./i386-elf-gcc --version
If so, proceed with the Step 3 and Step 4 on the project setup guide
to build the Emulator and Pintos Utility Tools. Make sure you set the SWD variable
to the path you choose above (e.g., ~/os/toolchain).
Afterward, you can do a full test on building Pintos. Assume ~/os/pintos
is where you cloned the Pintos repository:
cd ~/os/pintos/src/threads
make
cd build
pintos --bochs -- run alarm-zero
You should see the Pintos compilation finishes successfully and Bochs window shows up.
If the tools work, you can put export PATH=$HOME/os/toolchain/x86_64/bin:$PATH
in your .bashrc or .zshrc
