I've encountered problems compiling PHP from source at one 'a bit custom' Centos 6/cPanel server.In general it worked in the past, right now it does not. There were many different PHPs compiled at this box and without greater problems. Right now, any version of PHP is stuck at:

'Generating phar.phar'.

Some output:

Prerequisite `/root/php-7.0.13/ext/phar/phar/phar.inc' is older than target `ext/phar/phar/phar.inc'. No need to remake target `ext/phar/phar/phar.inc'.

I've tried make'ing and only 1 thread, and it did not help.

After 'clean' make:

I've tried to use make-4.2 instead of default make-3.81, but it changes nothing.

Some strace output:

  • Why do you want to compile php? Isn't it enough to install it from yum? Commented Feb 9, 2017 at 9:50
  • It can't be installed with yum, I need it as separate version for dev purposes. At this box it used to work, it stopped somehow, and I cannot trace the reason of such behavior. It is important for me to find solution, not workaround. Commented Feb 9, 2017 at 10:36

Solution found, right now it seems simple, shame I did not found it earlier. After strace'ing child processes it showed that it was using phar composer of another broken PHP build - and this child process was hung due to library dependency errors, so that's why process in question was waiting. After pointing to correct binary, it worked.
