# Build script for mupdf 1.28.0 (plain uname-keyed GNU Makefile, bundled
# thirdparty). NOT Template A/B - mupdf ships its own Makerules that
# selects behavior off `$(OS)` (defaulting to `uname`, which reports
# "Hammerhead" - matches none of mupdf's Darwin/Linux/OpenBSD/wasm arms),
# so force OS=Linux explicitly to pick up the Linux-shaped defaults
# (HAVE_OBJCOPY, LIB_LDFLAGS -shared -Wl,-soname, etc.) which line up with
# our GNU-ld/binutils toolchain.
#
# Use the BUNDLED thirdparty/ (freetype, harfbuzz, jbig2dec, openjpeg,
# mujs, zlib-alt) rather than USE_SYSTEM_LIBS=yes - avoids a large,
# fragile dependency reconciliation against our own freetype/harfbuzz
# ports for a single consumer. Only the X11 viewer libs (libX11/libXext/
# libXrandr/libXcursor) come from the system via pkg-config.
#
# Old (pre-2015-idiom-heavy in thirdparty/) C - GCC 14 promotes implicit-
# decl/incompatible-pointer-type/int-conversion to hard errors by default;
# -fpermissive demotes them back to warnings, -fcommon undoes GCC10+'s
# -fno-common default (tentative-definition multiple-definition errors).
