dnl === Basic setup =======================================================

AC_INIT([pfft markdown-to-PDF converter], [0.0.6], [], [pfft], [https://github.com/cxw42/pfft])

AC_PREREQ([2.65])

AC_COPYRIGHT([Copyright (C) 2020 Christopher White])

AC_CONFIG_SRCDIR([rules.mk]) dnl make sure the srcdir is correctly specified

AC_CONFIG_AUX_DIR([build-aux])

AC_CONFIG_MACRO_DIR([m4])

AM_INIT_AUTOMAKE([1.11 foreign subdir-objects])

dnl NOTE: If you add any variables to config.h, make sure to add them

dnl to src/myconfig.vapi as well.

AC_CONFIG_HEADER([config.h])

AC_PROG_CC

AC_PROG_CXX

AM_PROG_VALAC

dnl Known to work with valac 0.40.19

dnl TODO remove USER_VALAFLAGS once I figure out why regular VALAFLAGS

dnl isn't being passed through.

AC_ARG_VAR([USER_VALAFLAGS], [extra options for valac(1)])

AC_PROG_RANLIB

dnl === Code coverage =====================================================

dnl For some reason, the coverage data is referring to src/.../glib-2.0.vapi.

dnl Inject code to strip that from the .info file so genhtml can succeed.

dnl This is all very ugly. For example, the variables in this section are

dnl hardwired for use in a Makefile, since they assume Makefile syntax

dnl (embedded in sh(1) escaping).

dnl === Sanity checks =====================================================

dnl === Dependencies ======================================================
