If I compile on Linux x86, I will also have this issue. May I ask how to solve this problem?

After you compile Photino.Native you need to build your .NET app and move the binary into the bin/Debug/net6.0/runtimes/linux-arm64 and then start the app without building it again dotnet run --no-build. (see attached screenshot)

We noticed that the last release of Photino.Native unfortunately didn't include the binary for Linux ARM64 and will replace it with a package that does include it.

We don't support x86 platforms and have not tested them. The same method might apply here as well.

1.在运行Photino例子程序时，出现以下问题：

在ubuntu系统上运行正常，但是发布为arm64程序并在嵌入式arm64系统开发板是总是提示 Unable to load shared library 'Photino.Native' or one of its dependencies 我的解决办法是: 根据提示是Photino.Native.so文件的问题，然后使用file Photino.Native.so查看文件。我的提示 root@ok3568:~/blazor/linux-arm64# file Photino.Native.so Photino.Native.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=9252f20a763f988ffb41c32a11f25b2747a74239, not stripped
从返回的信息中可以看出此库位X64系统的库，于是就到官网下载了源代码，然后拷贝到arm64开发板使用makefile进行编译。具体步骤: 1.将下载的源代码文件拷贝到arm64开发板中 2.打开终端定位到photino.Native-2.4.1目录下，因为文件已经编译好了makefile文件直接使用make命令执行。具体命令如下 root@ok3568:~/photino.Native-2.4.1# make linux-arm64 3.编译时出错，提示错误: ./Photino.Native/Photino.Linux.cpp: In constructor ‘Photino::Photino(PhotinoInitParams*)’: ./Photino.Native/Photino.Linux.cpp:161:74: warning: comparison with string literal results in unspecified behavior [-Waddress] 161 | if (initParams->WindowIconFile != NULL && initParams->WindowIconFile != "") 从结果看是代码问题，就使用vi命令进入到代码将 && initParams->WindowIconFile != ""删除。然后再使用 make linux-arm64命令编辑就成功了。

4.使用file Photino.Native.so查看文件 root@ok3568:~/blazor/linux-arm64# file Photino.Native.so Photino.Native.so: ELF 64-bit LSB shared object, ARM arrch64, version 1 (SYSV), dynamically linked, BuildID[sha1]=9252f20a763f988ffb41c32a11f25b2747a74239, not stripped
说明此时生成的库为arm64系统的库，将此库拷贝到程序文件中，然后运行程序。 注意：因为其依赖webkit2gtk如果没有此库需要运行sudo apt-get update && sudo apt-get install libgtk-3-dev libwebkit2gtk-4.0-dev 备注：photino.Native-2.4.1下载地址https://codeload.github.com/tryphotino/photino.Native/zip/refs/tags/v2.4.1

Hello @anan1213095357!

We just released Photino.NET v2.5.0. This includes pre-compiled Photino.Native libraries for ARM64 operating systems including Linux. I tested this version successfully on the latest Debian version.

I'll close this issue for now, assuming this will work for you. But please let us know about your experience!
