This also removes the old Makefile based build-system. The immediate reason for adding support for meson is that this allows us to include edid-decode as a subproject in libdisplay-info. v3: * Declare a meson variable for the executable to make it possible to get it via subproject.get_variable() v2: * Remove the make build-system * Adjust the README on how to build/install with meson * Fix installing for the wasm-build Signed-off-by: Sebastian Wick <sebastian.wick@xxxxxxxxxx> --- Makefile | 50 --------------------------- README | 28 +++++++++------ emscripten/wasm-crossfile.txt | 14 ++++++++ meson.build | 65 +++++++++++++++++++++++++++++++++++ 4 files changed, 96 insertions(+), 61 deletions(-) delete mode 100644 Makefile create mode 100644 emscripten/wasm-crossfile.txt create mode 100644 meson.build diff --git a/Makefile b/Makefile deleted file mode 100644 index 375fedb..0000000 --- a/Makefile +++ /dev/null @@ -1,50 +0,0 @@ -ifeq ($(OS),Windows_NT) - bindir ?= /usr/bin - mandir ?= /usr/share/man -else - UNAME_S := $(shell uname -s) - ifeq ($(UNAME_S),Darwin) - bindir ?= /usr/local/sbin - mandir ?= /usr/local/share/man - else - bindir ?= /usr/bin - mandir ?= /usr/share/man - endif -endif - -EMXX ?= em++ - -SOURCES = $(wildcard *.cpp) -OBJECTS := $(patsubst %.cpp, %.o, $(SOURCES)) -EMOBJECTS := $(patsubst %.cpp, emscripten/%.o, $(SOURCES)) - -WARN_FLAGS = -Wall -Wextra -Wno-missing-field-initializers -Wno-unused-parameter -Wimplicit-fallthrough - -all: edid-decode - -sha = -DSHA=$(shell if test -d .git ; then git rev-parse --short=12 HEAD ; fi) -date = -DDATE=$(shell if test -d .git ; then TZ=UTC git show --quiet --date='format-local:"%F %T"' --format='%cd'; fi) - -edid-decode: $(OBJECTS) - $(CXX) $(LDFLAGS) -g -o $@ $(OBJECTS) -lm - -edid-decode.js: emscripten/edid-decode.js - -emscripten/edid-decode.js: $(EMOBJECTS) - $(EMXX) $(LDFLAGS) -s EXPORTED_FUNCTIONS='["_parse_edid"]' -s EXPORTED_RUNTIME_METHODS='["ccall", "cwrap"]' -o $@ $(EMOBJECTS) -lm - -%.o: %.cpp edid-decode.h oui.h Makefile - $(CXX) $(CPPFLAGS) $(CFLAGS) $(LDFLAGS) $(WARN_FLAGS) -g $(sha) $(date) -o $@ -c $< - -emscripten/%.o: %.cpp edid-decode.h oui.h Makefile - $(EMXX) $(CPPFLAGS) $(CFLAGS) $(LDFLAGS) $(WARN_FLAGS) $(sha) $(date) -o $@ -c $< - -clean: - rm -f *.o emscripten/*.o - rm -f edid-decode emscripten/edid-decode.js emscripten/edid-decode.wasm - -install: - mkdir -p $(DESTDIR)$(bindir) - install -m 0755 edid-decode $(DESTDIR)$(bindir) - mkdir -p $(DESTDIR)$(mandir)/man1 - install -m 0644 edid-decode.1 $(DESTDIR)$(mandir)/man1 diff --git a/README b/README index 4c2b7fe..bf4e668 100644 --- a/README +++ b/README @@ -6,8 +6,9 @@ To build this do: git clone git://linuxtv.org/edid-decode.git cd edid-decode -make -make install +meson setup _build +meson compile -C _build +meson install -C _build Patches and bug reports can be sent to the linux-media@xxxxxxxxxxxxxxx mailinglist (see https://www.linuxtv.org/lists.php).
