Description:
------------
trying to compile php 5.6 RC4

separately pdo-mysql and zlib extensions compile successfully, as well as if zlib is not shared, but if zlib is configured as shared, pdo-mysql extension fails to be built

Test script:
---------------
php-5.6.0RC4 gri$ ./configure --disable-all --enable-pdo --with-pdo-mysql --with-zlib=shared
...
php-5.6.0RC4 gri$ make
...
Undefined symbols for architecture x86_64:
  "_compress", referenced from:
      _php_mysqlnd_net_encode_pub in mysqlnd_net.o
  "_uncompress", referenced from:
      _php_mysqlnd_net_decode_pub in mysqlnd_net.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [sapi/cli/php] Error 1

Expected result:
----------------
build successful

Actual result:
--------------

The trick here appears to be to force pdo_mysql and mysqlnd to be built as shared as well, via ./configure --disable-all --enable-mysqlnd=shared --enable-pdo --with-pdo-mysql=shared --with-zlib=shared.

Reassigning to the MySQL team. I'm not sure if we can detect this in mysqlnd's config9.m4, but it might be worth looking at.

Is that still an issue with any of the actively supported PHP
versions[1]?

I build with a static zlib, and wrote the report just because met the error. It does not make big problems cause compilation is fast nowdays, but it worth to check this in a configure script and write a readable error without compilation, I guess.
I can check this with 7.4.

Well, I just tried on Debian with gcc and current PHP-7.4 head,
and the build showed no errors.  I'm assuming this has been fixed
in the meantime; please re-open if you are still experiencing
these issues.
