Cannot enable Freetype for gd in php 8.1.5 docker container

Question

Problem: Call to undefined function imagettfbbox. Output of function_exists('imagettfbbox') is false.

I've seen so many Dockerfiles now, and it seems not so difficult to enable Freetype with gd. However, although my Dockerfile builds without errors, Freetype is not enabled when I look at phpinfo...

What am I missing?

GD Support          enabled
GD Version          bundled (2.1.0 compatible)
GIF Read Support    enabled
GIF Create Support  enabled
PNG Support         enabled
libPNG Version      1.6.37
WBMP Support        enabled
XBM Support         enabled
BMP Support         enabled
TGA Read Support    enabled

Here's my Dockerfile

FROM php:8.1.5-fpm-alpine3.15

ENV PHP_OPCACHE_VALIDATE_TIMESTAMPS="0" \
    PHP_OPCACHE_MAX_ACCELERATED_FILES="20000" \

I also tried with `FROM php:8.0-fpm-alpine` and `FROM php:7.4-fpm-alpine3.13` with no luck. — Jos, May 01 '22 at 13:27
[This](https://github.com/laradock/php-fpm/blob/master/Dockerfile-8.1) Dockerfile seem to work fine, but the image is not "alpine". `--prefix=/usr` on `docker-php-ext-configure gd` does the trick. See the line `checking for FreeType 2... yes` in the configure output. Thanks. — Alexey Burdin, May 23 '22 at 12:26
Sadly not, I already had an external service running for the image creation which I'm now using for that purpose. I'm going to pick this up again one day, but it has no priority at the moment. If you find a solution, we would be happy to read it here ;-) — Jos, Jun 06 '22 at 08:00
[The manual](https://www.php.net/manual/en/function.imageftbbox.php) and [this question](https://stackoverflow.com/questions/49175139/trying-to-add-freetype-to-php-gd-in-docker-official-image) mention `--with-freetype-dir` (and not `--with-freetype` ) I've never done this myself so I don't know if this is the issue or if this is a red herring — apokryfos, Aug 08 '22 at 14:16

Maybe this could solve it:

RUN apk add --no-cache freetype-dev libjpeg-turbo-dev libpng-dev libzip-dev zlib-dev
RUN docker-php-ext-configure gd --enable-gd --with-freetype --with-jpeg
RUN docker-php-ext-install gd

I was able to build with the Freetype support using this Dockerfile

FROM php:8.1-fpm

RUN apt-get update \
    && apt-get install -y zlib1g-dev libpq-dev git libicu-dev libxml2-dev libcurl4-openssl-dev \
    pkg-config libssl-dev libzip-dev zlib1g-dev \
    libfreetype6-dev libjpeg62-turbo-dev libpng-dev

RUN docker-php-ext-configure gd --enable-gd --prefix=/usr --with-jpeg --with-freetype \
    && docker-php-ext-install -j$(nproc) gd

RUN php -r 'var_dump(gd_info());'

Since PHP 7.4 ...-dir options (like --with-freetype-dir, --with-jpeg-dir, etc.) were removed, so --prefix=/usr should be used.

gd_info() output

  ["GD Version"]=>
  string(26) "bundled (2.1.0 compatible)"
  ["FreeType Support"]=>
  bool(true)
  ["FreeType Linkage"]=>
  string(13) "with freetype"
  ["GIF Read Support"]=>
  bool(true)
  ["GIF Create Support"]=>
  bool(true)
  ["JPEG Support"]=>

  ["PNG Support"]=>

  ["WBMP Support"]=>

  ["XPM Support"]=>

  ["XBM Support"]=>

  ["WebP Support"]=>

  ["BMP Support"]=>

  ["AVIF Support"]=>
