Fatal error: Call to undefined function: imagejpeg() on Heroku PHP. Fix?

Question

So, I am getting the following error whilst trying to upload images on my Heroku site (PHP).

 Fatal error: Call to undefined function: imagejpeg() 

It refers to the following line in my AmazonS3Handler.php file.

    //build the jpeg
    imagejpeg($destinationImage);

Any ideas on how I could fix this?

Answer 1

I had GD lib installed and got the same error. The problem was in compiling without jpeg support. Here what you should do to make things work.

1. Install libjpeg

apt-get install libjpeg62-turbo-dev

2. Configure PHP with jpeg support

./configure \
--with-gd
--with-jpeg-dir=/usr/lib64
# other options

3. Build PHP

make clean
make
make install
