Failed to convert page to image. convert: symbol lookup error: /usr/lib/libraqm.so.0: undefined symbol: fribidi_get_bracket_types

I've installed Imagemagick, Ghostscript and poppel on Arch linux on a Aarch64 hardware (Odroid C2 like system). Arch kernel is 3.14.29 , I cannot upgrade the kernel and must stay on this.

I've also installed pdf-image module to use with node. When I try to convert a PDF file to jpg image I get the following error message:

`[test@test ~]$ node convertPdf2Jpg.js
Error occured: { message: 'Failed to convert page to image',
error:

stdout: '',
stderr: 'convert: symbol lookup error: /usr/lib/libraqm.so.0: undefined symbol: fribidi_get_bracket_types\n' }`

Here is the code that I have. (FYI, this code works perfectly on another Intel based Ubuntu machine with latest kernel).

`
var PDFImage = require("pdf-image").PDFImage;
var path = require('path');
var util = require('util');

function convertPDFTOJPG(pathToPdf) {

const pdfImageOpts = {
outputDirectory: path.join(__dirname, './images'),
convertExtension: 'jpg',
convertOptions: {
'-colorspace': 'RGB',
'-interlace': 'none',
'-density': '300',
'-quality': '100'
}
};

var pdfImage = new PDFImage(pathToPdf, pdfImageOpts);

pdfImage.convertPage(0).then(function (imagePath) {
// 0-th page (first page) of the slide.pdf is available as slide-0.png
console.log("Converted.");
fs.existsSync("./scan_000864.jpg") // => true
}, function (err) {
console.log("Error occured: " + util.inspect(err));
});

}

process.on('uncaughtException', function (err) {
console.log('Caught exception: ' + err);
});

convertPDFTOJPG("./scan_000864.pdf");
`

In fact on this Armv8 machine if I enter the command "convert" with or without any arguments, I immediately get the following error:

convert: symbol lookup error: /usr/lib/libraqm.so.0: undefined symbol: fribidi_get_bracket_types

I suspect the problem is due to old Kernel or the Armv8 / Aarch64 Architecture. Unfortunately I am married to both these elements (Kernel version as well as the Architecture) so I cannot upgrade or change either one. Please advice what can I do to fix this.

You need to update fribidi to version 1.0 or higher.
