compiling shared php-module as dll (windows)

i'm trying to compile a shared extension for php 8.3.6 x64 for windows i basicly followed these instructions: https://ourcodeworld.com/articles/read/804/how-to-compile-a-php-extension-dll-file-in-windows-with-visual-studio#disqus_thread

Problem: PHP Warning: PHP Startup: Unable to load dynamic library 'php_mailparse.dll' (tried: ./ext\php_mailparse.dll (Die angegebene Prozedur wurde nicht gefunden)) in Unknown on line 0

so what did i do:

installed basic components of Visual Studio 2019
create folder c:\php-sdk
extracted php-source from https://www.php.net/distributions/php-8.3.6.tar.gz into php-sdk
extracted contents of https://pecl.php.net/get/mailparse-3.1.6.tgz to php-sdk/ext/mailparse as of instructions i should run buildconf and configure, what it said binary tools are missing, so
downloaded https://github.com/php/php-sdk-binary-tools and extracted to php-sdk/php-sdk-binary-tools-master
open vs command prompt
goto php-sdk/php-sdk-binary-tools-master
run phpsdk-vs16-x64.bat
go back to php-sdk
run configure --disable-all --enable-cli --enable-mbstring --enable-mailparse --disable-zts --with-all-shared output:

run nmake

now in php-sdk\x64\Release i found a php_mailparse.dll, [edit] and copied it to the ext-folder of the precompiled php-binaries, [/edit] but this dll gives me the error written at the beginning ... anybody know what i've done wrong?

Solution

thanks to @shingo and a little experiment i got it working, as @shingo posted in his comment compiling shared php-module as dll (windows) i've done the following based on the instructions of https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2#building_pecl_extensions

i have installed Visual Studio Community 2019 with the following components (i don't know which one a really needed, just glad it worked overall ^^)

Desktopdevelopment with C++

MSVC v142 - VS 2019 C++ -x64/x86Buildtools

Windows 10 SDK

Just-In-Time-Debugger

C++-Profilingtools

C++-CMake-Tools for Windows

C++ AddressSanitizer

download php source from https://windows.php.net/download/ (example https://windows.php.net/downloads/releases/php-8.3.6-src.zip)
download php binary tools from https://github.com/php/php-sdk-binary-tools
download pecl extension src from https://pecl.php.net/package/mailparse

now:

create folder C:\php-sdk
extract php-source to C:\php-sdk (now i had the php source in C:\php-sdk\php-8.3.6-src)
extract contents php-sdk-binary-tools-master.zip\php-sdk-binary-tools-master to C:\php-sdk (so that for exmaple phpsdk-vs16-x64.bat will be in C:\php-sdk)
go into php-src-folder (C:\php-sdk\php-8.3.6-src in my case) and create a folder "pecl"
extract src of extension to C:\php-sdk\php-8.3.6-src\pecl (in my case mailparse, so i had a folder C:\php-sdk\php-8.3.6-src\pecl\pecl-mail-mailparse-master, but i renamed it to C:\php-sdk\php-8.3.6-src\pecl\mailparse)

now open command prompt:

cd C:\php-sdk
phpsdk-vs16-x64.bat
cd php-8.3.6-src
buildconf
configure --disable-all --enable-cli --enable-mbstring=shared --enable-mailparse=shared --disable-zts (--disable-zts because i'm compiling for fastcgi under iis, also --enable-mbstring=shared was necessary, since mailparse depends on mbstring, without it, it did not work)
nmake

now i copied php_mbstring.dll and php_mailparse.dll from C:\php-sdk\php-8.3.6-src\x64\Release to the extension-folder of my running prebuild php-binaries ext-folder, REPLACING the existing php_mbstring.dll and now it works ;)
