Failing to build caused by missing header #6

Closed Donnyp751 closed 1 year ago

Donnyp751 commented 1 year ago

Hello, I'm having trouble getting the libimxdmabuffer to compile for the IMX6Q as my toolchain sysroot doesn't seem to contain the linux/mxcfb.h header file. I'm wondering how to obtain this or resolve this error to get the package building? It looks like this issue had cropped up before but I couldn't find a resolution publicly.

Command being ran to build: ./waf configure --prefix=$PREFIX --imx-linux-headers-path=/usr/arm-buildroot-linux-gnueabihf/sysroot/usr/include

Error encountered: Checking for header linux/mxcfb.h : not found Could not find linux/mxcfb.h in path "/usr/arm-buildroot-linux-gnueabihf/sysroot/usr/include" specified by --imx-linux-headers-path

Hi, it's an old issue but try to add DEPENDS = "linux-imx-headers" in your libimxdmabuffer recipe file. This should solve it.

I'm changing the check, since mxcfb.h is no longer included in some sysroots. I'm closing this for now though, since it is a BSP issue. If you still have problems, and they are caused by libimxdmabuffer issues, please open a new issue.
