[5.8] Possible undocumented dependency

[GrahamCampbell]

When I run Laravel's test suite on one of my machines, I run into the following issue:

1) Illuminate\Tests\Http\HttpTestingFileFactoryTest::testImageJpeg
Error: Call to undefined function Illuminate\Http\Testing\imagejpeg()

/data/src/Illuminate/Http/Testing/FileFactory.php:55
/data/src/Illuminate/Support/helpers.php:1124
/data/src/Illuminate/Http/Testing/FileFactory.php:63
/data/src/Illuminate/Http/Testing/FileFactory.php:34
/data/tests/Http/HttpTestingFileFactoryTest.php:23

Do you have PHP GD extension installed?

[GrahamCampbell]

Hmm, actually, yes.

graham@Grahams-MBP framework % php73 -m | grep gd
gd

[GrahamCampbell]

Kinda odd the function is not defined... Maybe it was compiled with an old version of the C lib?

[GrahamCampbell]

graham@Grahams-MBP framework % php73 -r "var_dump(extension_loaded('gd'), function_exists('imagejpeg'));"
bool(true)
bool(false)

[GrahamCampbell]

graham@Grahams-MBP framework % php -r "var_dump(gd_info());"
array(12) {
  ["GD Version"]=>
  string(26) "bundled (2.1.0 compatible)"
  ["FreeType Support"]=>
  bool(false)
  ["GIF Read Support"]=>
  bool(true)
  ["GIF Create Support"]=>
  bool(true)
  ["JPEG Support"]=>
  bool(true)
  ["PNG Support"]=>
  bool(true)
  ["WBMP Support"]=>
  bool(true)
  ["XPM Support"]=>

Alright, that's an issue outside of Laravel's control... docker-library/php#881.

[fiskolini]

The problem was in compiling without jpeg support.

Seems like missing libjpeg extension.
