Bug #67849 [Asn->Csd]: error compiling mysqlnd if zlib is compiled shared

Edit report at https://bugs.php.net/bug.php?id=67849&edit=1 ID: 67849 Updated by: cmb@php.net Reported by: public at grik dot net Summary: error compiling mysqlnd if zlib is compiled shared -Status: Assigned +Status: Closed Type: Bug Package: MySQL related Operating System: Linux, OSX 10.9 PHP Version: 5.6.0RC4 Assigned To: cmb Block user comment: N Private report: N New Comment: 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. Previous Comments: ------------------------------------------------------------------------ [2021-02-01 16:16:12] public at grik dot net 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. ------------------------------------------------------------------------ [2021-02-01 15:29:17] cmb@php.net Is that still an issue with any of the actively supported PHP versions[1]?

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. ------------------------------------------------------------------------ [2014-08-15 14:35:41] public at grik dot net 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 ...
