Tool/software: Linux
What is the latest version of Graphics SDK that I can use with OMAP3530 running Linux kernel 2.6.29.6?
I am trying to upgrade a legacy device with newer software using Qt 5.8. The device uses OMAP3530 processor with Linux kernel based on 2.6.29.6. (We don't have the option to upgrade to a newer kernel.) Currently, we use Graphics SDK 3.01.00.02 (with a minor patch). In its EGL/eglext.h, this version of SDK uses EGL extension version 3, as indicated by the following macro:
#define EGL_EGLEXT_VERSION 3
QtWebEngine shipped within Qt 5.8 requires that we use EGL extension version 4, which seems to be introduced in Graphics SDK 4.06. However, I cannot seem to compile the kernel modules in the newer SDK against Linux kernel based on 2.6.29.6. Here is my attempt:

The missing file, omapfb.h, is found in my system in a different directory:
precor@SEAL9004:~/Graphics_SDK_4_06_00_03$ locate omapfb.h
/home/precor/workdir/lsp/linux-2.6.29_omap3515/arch/arm/plat-omap/include/mach/omapfb.h
/home/precor/workdir/lsp/linux-2.6.29_omap3515/drivers/video/omap2/omapfb.h
I am not sure if it is as simple as trying to change the path to this include file within dc_omapfb3_linux/omaplfb_linux.c. I have attempted to do so and still get compiler errors.
The last 4.x series SDK that I have been able to successfully compile against the current kernel is 4.03.00.02. Unfortunately, this version does not have the EGL extensions we need.
I have noticed that while compiling 4.03, the system picks up the offending file from a different directory.
4.03.00.02:
Graphics_SDK_4_03_00_02/GFX_Linux_KM/services4/3rdparty/dc_omap3430_linux/omaplfb_linux.c
4.06.00.03:
Graphics_SDK_4_06_00_03/GFX_Linux_KM/services4/3rdparty/dc_omapfb3_linux/omaplfb_linux.c
So it looks like omaplfb_linux.c within dc_omap3430_linux compiles with 2.6.29.6, but the one within dc_omapfb3_linux does not.
I will state my question differently.
What is the minimum Linux kernel version needed to compile 4.06 for OMAP3530? Or better, 5.x of Graphics SDK?
We are using a softfp toolchain.
Here is the patch I need to compile Graphics SDK 4.03.00.02:
