configure: error: Unable to detect ICU prefix or /usr/bin/icu-config failed. Please verify ICU install prefix and make sure icu-config works.

Please checkout the build log file for more details:

Should be related to the Debian Bug #898820.

The problem is fixed in PHP 7.4 (https://github.com/php/php-src/pull/3701).

I think the same patch should have done that too? Try ‘phpbrew ext install intl’

Interestingly, I can install INTL as a shared extension using phpbrew ext install intl but I cannot compile PHP with it as I used to on Ubuntu 16.04.

How do you think is the patch for ext/gd/config.m4 relevant to ext/intl/config.m4?

I'm not sure sorry, I don't use this extension in my projects, I was mistaken on my comment on the other issue.

As a workaround, I compiled ICU and copied ico-config to /usr/bin.

See this gist for icu-config for Ubuntu 20.04 LTS.

Took me a moment to understand what @jasny meant. Hereby the for-dummies:

• Take the raw script and save it on your machine:
  
  
  
  • curl https://gist.githubusercontent.com/jasny/e91f4e2d386e91e6de5cf581795e9408/raw/16e2c42136eb3f214222c80d492e71942b77f174/icu-config > icu-config
  
  
  • OR
  
  
  • wget https://gist.githubusercontent.com/jasny/e91f4e2d386e91e6de5cf581795e9408/raw/16e2c42136eb3f214222c80d492e71942b77f174/icu-config
  
  
• Make the file executable:
  
  
  
  • chmod +x icu-config
  
  
• Move the file to /usr/bin
  
  
  
  • sudo mv icu-config /usr/bin
  
  

Now try to rerun phpbrew.
