Answer 1

phpize
make
make install

Answer 2

pcntl belongs to the source code that comes with php
https://github.com/php/php-src/tree/master/ext/pcntl

First compile and installphp，并可以成功的执行phpize

cd php-src/ext/pcntl
phpize
./configure
make

cp modules/pcntl.so /your/php/ext/dir/

Requires ./configure

----------------------------------------------------------------------
Libraries have been installed in:
   /root/php-src-php-7.1.4/ext/pcntl/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------

Build complete.
Don't forget to run 'make test'.
