With automake-1.16, code like > AM_PATH_PYTHON([$PYTHON_VERSION]) or > AM_PATH_PYTHON([$PYTHON_MIN_VERSION]) as found in https://gitlab.com/cryptsetup/cryptsetup/blob/master/configure.ac#L506 https://github.com/ImageMagick/PythonMagick/blob/master/configure.ac#L42 doesn't work anymore: > ***** aclocal ***** > ***** PWD: /var/tmp/portage/sys-fs/cryptsetup-2.0.1/work/cryptsetup-2.0.1 > ***** aclocal -I m4 > > /usr/bin/m4:configure.ac:506: bad expression in eval (bad input): ($+1) != (2) > /usr/bin/m4:configure.ac:506: bad expression in eval (bad input): > (0r36:PYTHON_+1) != (0*4) > autom4te-2.69: /usr/bin/m4 failed with exit status: 1 > aclocal-1.16: error: echo failed with exit status: 1 -- Regards, Thomas Deutschmann / Gentoo Linux Developer C4DD 695F A713 8F24 2AA1 5638 5849 7EE5 1D5D 74A5
