nao carregou o PDFium em

Error message

nao carregou o PDFium em {}: {}

What it means

api() wraps libloading::Library::new failure with this message after a path was resolved. The library file was found but could not be loaded as a dynamic library — wrong architecture, missing transitive dependencies, corrupted file, or insufficient permissions. The message includes the path and the OS loader error, which is the key diagnostic.

Solutions

1. Read the inner libloading/OS error in the message to identify the load failure cause
2. Install the PDFium build matching the app's architecture and platform
3. On Linux install missing shared-library dependencies (ldd the pdfium file); on macOS clear the quarantine attribute (xattr -d com.apple.quarantine)
4. Re-download/reinstall PDFium — the file may be truncated or corrupted

Example fix

// before
let pages = pdf::render(path, opts)?; // 'nao carregou o PDFium em /opt/.../libpdfium.so: ...'
// after
match pdf::render(path, opts) {
    Err(e) if e.to_string().contains("nao carregou o PDFium") => {
        repair_pdfium_install()?; // reinstall correct arch + deps
        let pages = pdf::render(path, opts)?;
    }
    r => r?,
}

fn pdfium_loadable(p: &std::path::Path) -> Result<(), String> {
    // loader-level probe
    match unsafe { libloading::Library::new(p) } {
        Ok(_) => Ok(()),
        Err(e) => Err(format!("falha ao carregar {}: {e}\nVerifique arquitetura e dependências do sistema.", p.display())),
    }
}

match pdf::split(&path, &out_dir) {
    Err(e) if e.to_string().contains("nao carregou o PDFium") => {
        eprintln!("{e}\nReinstale o PDFium da arquitetura correta via Ajustes → Dependências.");
    }
    other => other?,
}

When it happens

Trigger: Calling any PDF operation when the resolved PDFium file cannot be dlopen'd/LoadLibrary'd: 32/64-bit mismatch, missing libstdc++/libc++ deps of pdfium, quarantine/provisioning blocking load on macOS, truncated download.

Common situations: Downloading the wrong-architecture pdfium binary; on Linux missing system libs pdfium links against; macOS Gatekeeper quarantine bit; partially downloaded library file.
