Windows php上使用的libvips ffi无法找到glib函数
我正在尝试在Windows 11上使用Libvips软件包。
我已经安装了Composer软件包“ JCUPITT/VIPT”：“ 2.0.0”
我的本地PHP设置是Laragon，我已启用了FFI Extension用于php。
我已经为Windows安装了Libvips二进制文件，并将其添加到路径中。当我直接从命令行调用它时，它起作用。示例：vips invert.png output.png
运行以下文件（使用FFI）：
<?php
require dirname(dirname(__DIR__)) . '/vendor/autoload.php';
use Jcupitt\Vips;
// fast thumbnail generator
$image = Vips\Image::thumbnail('example-rug.jpg', 128);
$image->writeToFile('tiny.jpg');

我只能认为这是两个GLIB功能，也许我没有Glib DLL文件？
我检查了VIP bin文件夹，并在那里找到了libglib-2.0-0.dll。这在同一bin文件夹中，因此应在必要时在路径上找到。
我知道正在通过libvips-42.dll将其拉入，因为如果我重命名libglib-2.0-0.dll file，则FFI输出将变为：
致命错误：未被发现的ffi \异常：失败加载'libvips-42.dll'
我可以提供的最后一个信息是，FFI的命令的有问题部分似乎是：
void* g_malloc (size_t size);
void g_free (void* data);
I am attempting to use the libvips package on Windows 11.
I have installed the composer package "jcupitt/vips": "2.0.0"
My local PHP setup is laragon, and I have enabled the FFI extension for PHP.
I have installed libvips binary for Windows and added it to the path. It works when I call it from the command line directly. Example: vips invert input.png output.png
When running the following file (which uses FFI):
<?php
require dirname(dirname(__DIR__)) . '/vendor/autoload.php';
use Jcupitt\Vips;
// fast thumbnail generator
$image = Vips\Image::thumbnail('example-rug.jpg', 128);
$image->writeToFile('tiny.jpg');

All I could think is that these are 2 glib functions and maybe I do not have the glib dll file?
I checked the vips bin folder, and libglib-2.0-0.dll is found there. This is in the same bin folder, so it should be found at the path if necessary.
I know this is being pulled in via the libvips-42.dll, because if I rename libglib-2.0-0.dll file, the FFI output becomes:
Fatal error: Uncaught FFI\Exception: Failed loading 'libvips-42.dll'
The last bit of info I can provide is that the offending portion of the command fed to FFI appears to be:
void* g_malloc (size_t size);
void g_free (void* data);

猜测
libvips-42.dll必须手动提供：https://github.com/libvips/libvips/build-win64-mxe/releases
Guess
libvips-42.dllhas to be manually provided:https://github.com/libvips/build-win64-mxe/releases
这是在v2.0.3中修复的：
https://github.com/github.com/libvips/libvips/php-php--php--php--php--php-- vips/pult/146
只需更新即可（希望）。
This is fixed in v2.0.3:
https://github.com/libvips/php-vips/pull/146
Just update and it'll work (hopefully).
