DESCRIPTION:

In the hopes of fixing a build/debug issue, I did an upgrade to 3.5. This resulted in a project I could build this morning producing this output:

sfdk: [I] Options from environment: -c target=SailfishOS-3.4.0.24-armv7hl
error: Failed build dependencies:
	pkgconfig(SDL2_mixer) is needed by harbour-simplesynth-0.1-1.armv7hl
	pkgconfig(sdl2) is needed by harbour-simplesynth-0.1-1.armv7hl

great.

PRECONDITIONS:

Use 3.4 SDK to build a project (subdirs style) with a dependency on SDL2 (presumably) and upgrade to 3.5.

STEPS TO REPRODUCE:

  1. build a project with pkgconfig(SDL2_mixer), pkgconfig(SDL2) (in this case, in spec and .pro)
  2. compile with 3.4
  3. upgrade to 3.5 sdk
  4. attempt to compile.

EXPECTED RESULT:

Ah, compilation of the binary and deployment as in 3.4

ACTUAL RESULT:

Errors.

Can I downgrade. This really sucks.

#2

include <SDL2/SDL.h> is no longer found. WTFruitcake is going on here!?

#3

Hmmmm. After several attempts at building, the SDK did something ‘magical’ (after I removed the pkgconfig directives, failed build and added them back in).

'pkgconfig(sdl2)' not found in package names. Trying capabilities.
'pkgconfig(SDL2_mixer)' not found in package names. Trying capabilities.
