I'm working on CMAKE build of latest Krypton-master in a raspbian chroot for RPI2.

For RPI2 with autofoo, I see

Code:

./configure --with-platform=raspberry-pi2 ...

Looking in "project/cmake/..." source, I'm not seeing any reference to rpi2

What's the correct RPi2-ready cmake build config for Krypton, equivalent to I suppose

Code:

cmake ../project/cmake/ -DPLATFORM=raspberry-pi2 ...

?

I've attempted a variety of build configs

Code:

cmake ../project/cmake/ -DPLATFORM=raspberry-pi ... (varied options) ...
cmake --build . -- VERBOSE=1 -j4

but currently am stuck at "invalid use of incomplete type ‘class CMMALBuffer’" errors in the build,

Code:

Not clear yet if that's a result of the 'wrong' platform (RPi1 vs RPi2), or can be worked-around with the right mix of configs.

I've searched forums for "CMMALBuffer" with not much luck yet.

Is there any guide yet for a successful CMAKE on RPI2 build config?

Have you read this thread; http://forum.kodi.tv/showthread.php?tid=288739

@popcornmix

I have now. Not clear specifically what you're referring to re: CMMAL*.

1 step at a time, then, the relevant bits appear to be

Code:

cmake ../project/cmake \
-DCORE_SYSTEM_NAME=rbpi -DCPU=cortex-a7 -DCMAKE_C_FLAGS="-fPIC -mcpu=cortex-a7 -mfloat-abi=hard -mfpu=neon-vfpv4" -DCMAKE_CXX_FLAGS="-fPIC -mcpu=cortex-a7 -mfloat-abi=hard -mfpu=neon-vfpv4"

With that atm, starting with clean Krypton-master sources, building for RPi2, 1st returns an error

Code:

...
CMake Error at scripts/rbpi/ArchSetup.cmake:7 (string):
  string sub-command REGEX, mode REPLACE needs at least 6 arguments total to
  command.
Call Stack (most recent call first):
  scripts/common/ArchSetup.cmake:95 (include)
  CMakeLists.txt:28 (include)
...

Reading at

Code:

https://cmake.org/pipermail/cmake/2004-June/005165.html

suggests quoting the last argument(s)

Code:

edit scripts/rbpi/ArchSetup.cmake
    ...
    -    string(REGEX REPLACE "[ ]+" ";" SYSTEM_LDFLAGS $ENV{LDFLAGS})
    +    string(REGEX REPLACE "[ ]+" ";" SYSTEM_LDFLAGS "$ENV{LDFLAGS}")
    ...

which does get 'cmake ...' past the initial error, but continues on to additional/similar errors

Code:

...
CMake Error at scripts/rbpi/Macros.cmake:34 (string):
  string sub-command REGEX, mode REPLACE needs at least 6 arguments total to
  command.
Call Stack (most recent call first):
  modules/FindCpluff.cmake:34 (core_link_library)
  scripts/common/Macros.cmake:307 (find_package)

...

But, sanity-checking, this only occurs in the RPi2 Raspbian chroot; on linux, no such errors.

Fyi, in Raspbian

Code:

cmake --version
    cmake version 3.6.1

In linux64 native env,

Code:

cmake --version
    cmake version 3.7.0

EDIT: upgrade to

Code:

apt-get install -t stretch cmake
cmake --version
    cmake version 3.7.0

returns same error.

EDIT2: the not-on-linux behavior looks like a result of inconsistencies in usage; note some quoting, some lacking
