hi 

imx8mini

imx-yocto-L4.14.98_2.0.0_ga

I want to use libimxdmabuffer ,but I compile  failed  .

从编译错误 信息来看,应当时版本不对。

libimxdmabuffer 是从freescale的github上下载的。按理不会报错。

请指导一下怎么正确编译

how did you build this? we don't use github.freescale.com anymore, the source code was moved to "https://source.codeaurora.org/external/imx", try to change the "git://git.freescale.com/imx " to "https://source.codeaurora.org/external/imx"
