在ubuntu 22.04的嵌入式服务器系统上报：could not initialize canvas

[kevin406972552]

在ubuntu22.04
下载源码后meson build 发现生成的.so只有8.2kb，ninja ---> ninja install 后，把安装目录的.so文件覆盖到系统/usr/lib/aarch64-linux-gnu/目录下
运行glmark2-es2-drm 报错：

同样的方法在ubuntu23.10系统下，能正常运行glmark2-es2-drm

pls try to test it with newest glmark2

[kevin406972552]

两个系统环境下用的同样的glmark2-es2-drm版本，都是
apt update
apt install glmark2-es2-drm 安装的。
最大的问题是在ubuntu22.04下ninja install 生成的

-rwxr-xr-x 1 root root 8.2K Apr 15 15:07 libGLESv2.so.2 等等都异常的小。

我也试过只把下面的覆盖过去，也不行

[JeffyCN]

they are expected to be small.

pls use the same glmark2 to test. (there's a knowing issue about old glmark2, it should be fixed in newer version)

在ubuntu23.10的文件系统情况下，刚刚还做了Qt的交叉编译：
1：在没更换编译出来的库时，config正常通过，并支持opengl
2：在更换编译出来的库后却报egl，eglfs，opengl es2 依赖库的错误

For Debian-based OSs, this libmali uses vendor packaging, which would conflict with the unified libmali library(vendor packaging requires multiple sonames).
So there would be some dummy(smallest) libraries to wrap the libmali.
This requires third-party packages to get compiling flags through pkg-config(which would provide -lmali in ldflags) instead of being hard-coded in their build scripts.

The suggested way to use this libmali on Debian-based OS would be:
1/ Remove it when compiling other packages.
2/ Install it only when you are about to use it.
