| Problem | Likely Fix | |---------|-------------| | module 'pdf' not found | Run v install pdf again. | | Font not rendering | Use standard fonts: Helvetica, Times, Courier. | | Text upside-down | Remember Y=0 is bottom-left. Use page_height - y for top-left orientation. | | PDF corrupt | Ensure you call doc.save() before program exits. |

If you want, I can:

(Note: Related search suggestions provided.)

Create a file named hello.v:

fn main() 
    println('Hello, V world!')

Run it:

v run hello.v

Output:

Hello, V world!

To compile a standalone binary:

v hello.v
./hello

Open your terminal and run:

git clone https://github.com/vlang/v
cd v
make
sudo ./v symlink

Verify installation:

v --version
