RE: HOWTO: Building Apache and dependencies using CMake

tangent — Fri, 19 Jun 2026 13:01:09 GMT

Release 5.0 includes the following build dependency updates:

OPENSSL (3.6.3)

Other changes are to build the mod_proxy_uwsgi module, which is omitted from the ASF CMake build for some reason.

A section to build ZSTD (1.5.7) libraries has been added, to aid future support for this compression standard.

A bunch of historical release comments have also been removed for clarity; previous details for this topic if needed can be found at https://web.archive.org.

RE: PHP 8.5.7 and curl 8.20.0 require loading of brotli and zstd

tangent — Fri, 19 Jun 2026 09:21:04 GMT

Thanks to you and @Jan-E for following this through with the PHP developers so quickly, and yes, it looks like their solution going forward will be to link with ZSTD statically. So there will be no need to change the ZSTD names in the Apache Lounge build.

What's interesting in looking through the PHP post is reference to winlib-builder patch https://github.com/winlibs/winlib-builder/blob/master/patches/libzstd.patch, where a decision was made to change the ZSTD library names from zstd to libzstd. This is what has caused this issue, in a similar way to the problems ZLIB caused by changing the names of their libraries in their most recent update.

The downside of linking things statically is programs sizes and memory requirements go up; like most things in life it's a compromise.

Regarding the 'ecosystem' needing to adapt, we are looking at the Open Source movement. There are some really clever guys out there, who as developers choose to give their own time and expertise in co-operative ventures to the best of their abilities. I take my hat off to them.

RE: PHP 8.5.7 and curl 8.20.0 require loading of brotli and zstd

danielruf — Fri, 19 Jun 2026 06:07:47 GMT

Frankly I can not answer, why PHP builds libzstd.dll. As far as I understood, they statically build and include the library via cmake or something like that.

Good news is, that it should not happen with the next PHP release, see https://github.com/php/php-src/issues/22359#issuecomment-4745323072

* copied the file as mentioned in apache/bin (zstd.dll => libzstd.dll).
* removed LoadFile "${basePath}/php/libzstd.dll" from my httpd.conf.
* restarted the Apache service
* reloaded page with phpinfo output
* curl is successfully loaded now

So it seems it is connected to the lib* => * renaming. Something similar happenend with zlib. Why that is so? I don't know.

To me as someone from the outside it looks like this:
* curl changed their requirements (breaking change imho, made in a minor update)
* the whole ecosystem has to adapt (PHP, Apache and likely other distros, packages, ...)

Not sure if and how well this was communicated in the ecosystem.

I've been looking into this issue and trying to reason it through.

Since you say your setup works without specifying the PHP based brotlidec.dll file, that rather suggests it's happy with the Apache bundled version (which I'd expect).

So out of interest, I wonder what happens if you copy the Apache zstd.dll to a file named libzstd.dll, whether Apache will then start without the extra PHP LoadFile directive?

For some reason it would seem the PHP (8.5.7) build process (winlib-builder) chooses a different name for the ZSTD libraries compared to those which come with the standard CMake build on Windows.

Code:

ZSTD PHP
----- -----
zstd.dll libzstd.dll
zstd.lib libzstd.lib

....

Understood, thank you.

I've now added only the following, instead of brotlidec + libzstd:

LoadFile "${basePath}/php/libzstd.dll"

This seems to work (we generally load the versions shipped with the PHP builds for Windows).

I'll try to report the requirement for this LoadFile in the PHP project. Maybe ther eis something that can be fixed / improved. At least to me it makes not much sense to manually add this, when the libraries are there in Apache and PHP is running as Apache module.

Edit: opened an issue at https://github.com/php/php-src/issues/22359 - maybe some mismatch leads to this

I'm not sure I understand.

My question basically boils down to: why do we even have to manually add some LoadFile entries for the curl extension?

Is this expected and if so, should this be documented somewhere? Why was zstd then included but I still need the LoadFile entry?

Apache has shipped with brotlidec.dll for a long time now, so the fact you're having to name a specific path to a brotlidec.dll image with a LoadFile directive, is somewhat surprising.

Also notable, when building zstd with CMake (as per the new AL build), the default DLL filename produced by the package is zstd.dll not libzstd.dll

PHP 8.5.7 and curl 8.20.0 require loading of brotli and zstd

danielruf — Tue, 16 Jun 2026 06:45:03 GMT

It seems newer PHP versions (also includes PHP 8.4.x) ship with curl 8.20.0, which requires to load brotli(dec.dll) and (lib)zstd(.dll).

Otherwise Apache fails to start, when one of the newer PHP releases with curl 8.20.0 or newer is used.

Is this on the radar of the ApacheLounge team? Will there be some changes in the ApacheLounge Apache builds or is this just something that has to be documented, so PHP users are aware of it and related bugreports can be pointed to the documentation?

Thank you for your response and apologies that we missed your earlier request.

The AL filename format changed with the switch to CMake builds, since the source official template file docs/conf/httpd.conf.in contains the references to access_log and error_log which end up in httpd.conf.

For as long as I can remember those have been the default names when building with CMake or using the configure script under Linux. The only exception I know is Apache builds on Ubuntu, which defaults to access.log and error.log.

We are not changing it. It is part of the official Apache source code.

You have to change it manual.

RE: build 67 missing zlib1.dll?

The switch to ZLIB 1.3.2 was picked up in Apache HTTPD release 2.4.67-260504 back in May, based on the CMake build HowTo (which switched to ZLIB 1.3.2 back in February). There is some discussion of that change and it's impact at https://www.apachelounge.com/viewtopic.php?p=44136#44136

Notably, as you have found, the various ZLIB libraries were renamed.

Code:

1.3.1 1.3.2
----- -----
bin\zlib1.dll bin\z.dll
lib\zlib.lib lib\z.lib
lib\zlibstatic.lib lib\zs.lib

Significantly, the developer's decision to change the naming convention for the libraries caused quite a lot of discussion on the net, e.g. https://github.com/madler/zlib/issues/1181

It's adverse effect on various packages such as PHP, was also discussed in detail, e.g. ....

RE: HOWTO: Building Apache and dependencies using CMake

tangent — Fri, 12 Jun 2026 09:39:04 GMT

Release 4.9 includes the following build dependency updates:

EXPAT (2.8.1)
HTTPD (2.4.68)

Script updated to add an "Apache Lounge VSxx" string prefix to the HTTPD startup message (and build info "httpd -v").

The script also includes updates to optionally support (OFF by default), a new Segment Heap functionality Microsoft has added to VS18 as of release 18.6.0 (May 2026); described here https://devblogs.microsoft.com/cppblog/segment-heap-support-for-c-projects-in-visual-studio.

Microsoft claim this Segment Heap feature improves heap stability, and "provides protection against memory vulnerabilities". Note this functionality only applies to executables, not libraries. Posts on the Internet suggest the jury is still out on this feature.

An unnecessary (legacy) edit of file apr.hw has been removed from the APR build logic.

CURL options to include SMB and NTLM support (where CURL >= 8.20.0) have been added. Thanks for @Jan-E for picking up on this issue https://www.apachelounge.com/viewtopic.php?p=44354

Although OPENSSL (3.6.3) has just been released, the decision has been made to defer updating the build to this latest OPENSSL release at this time.
