Bug 698852 – dev-util/glslang-7.12.3353_pre20191027 - CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:137 (message): Could NOT find PythonInterp: Found unsuitable version "2.7.16", but required is at least "3" (found /usr/bin/python)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Ilia Mirkin 2019-10-29 14:20:48 UTC]

It appears to require python3, but attempts to invoke python instead:

CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find PythonInterp: Found unsuitable version "2.7.16", but
  required is at least "3" (found /usr/bin/python)
Call Stack (most recent call first):
  /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:376 (_FPHSA_FAILURE_MESSAGE)
  /usr/share/cmake/Modules/FindPythonInterp.cmake:166 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  CMakeLists.txt:157 (find_package)

CMake is a mystery to me, so not sure what the proper place to address this is.

Reproducible: Always

Ebuilds need:

PYTHON_COMPAT=(python{3_6,3_7})

inherit python-any-r1

BDEPEND="${PYTHON_DEPS}"
