sudo apt install llvm-dev libclang-dev clang

Apache httpd

• Install system packages

sudo apt install apache2-dev libapr1-dev

Build

FFI

• Build project

cargo build
cargo test --lib

Apache httpd module

• Build Apache httpd module mod_example

cd examples/mod_example/
cargo build

Test

Locally

• Build and install modules

cd examples/mod_example/
cargo build
sudo apxs -i -a -n example ./target/debug/libmod_example.so

cd examples/mod_sum/
cargo build
sudo apxs -i -a -n sum ./target/debug/libmod_sum.so

• Add module configurations

sudo tee /etc/apache2/mods-available/example.conf > /dev/null <<EOT
<IfModule example_module>
    <Location "/example">
        SetHandler example-handler
    </Location>
</IfModule>
EOT
sudo a2enmod example

sudo tee /etc/apache2/mods-available/sum.conf > /dev/null <<EOT
<IfModule sum_module>
    AddHandler sum-handler .sum
</IfModule>
EOT
sudo a2enmod sum

• Restart Apache httpd to load configuration

sudo systemctl restart apache2

• Navigate to http://localhost/example

• Navigate to http://localhost/any/path.sum
