From 10d5bde8d628a93993dd7305dc9a406da69f65a9 Mon Sep 17 00:00:00 2001 From: Peter Seiderer Date: Wed, 2 Dec 2015 00:22:26 +0100 Subject: [PATCH] Adjust for buildroot build. - enable CC override - fix devLib/gpio include path for local build (without installing first) - change CFLAGS from '=' to '+=' to honour buildroot given flags - add linker name link for libwiringPiDev and libwiringPi for local linking (without installing first) - fix install linker name link (do not link with absolute path) - add gpio-static linking target Signed-off-by: Peter Seiderer --- devLib/Makefile | 9 +++++---- gpio/Makefile | 14 +++++++++----- wiringPi/Makefile | 7 ++++--- 3 files changed, 18 insertions(+), 12 deletions(-) diff --git a/devLib/Makefile b/devLib/Makefile index 1b1ebe0..84b4d2a 100644 --- a/devLib/Makefile +++ b/devLib/Makefile @@ -36,10 +36,10 @@ DYNAMIC=libwiringPiDev.so.$(VERSION) #DEBUG = -g -O0 DEBUG = -O2 -CC = gcc -INCLUDE = -I. +CC ?= gcc +INCLUDE = -I../wiringPi DEFS = -D_GNU_SOURCE -CFLAGS = $(DEBUG) $(DEFS) -Wformat=2 -Wall -Winline $(INCLUDE) -pipe -fPIC +CFLAGS += $(DEBUG) $(DEFS) -Wformat=2 -Wall -Winline $(INCLUDE) -pipe -fPIC LIBS = @@ -69,6 +69,7 @@ $(STATIC): $(OBJ) $(DYNAMIC): $(OBJ) $Q echo "[Link (Dynamic)]" $Q $(CC) -shared -Wl,-soname,libwiringPiDev.so$(WIRINGPI_SONAME_SUFFIX) -o libwiringPiDev.so.$(VERSION) -lpthread $(OBJ) + $Q ln -sf libwiringPiDev.so.$(VERSION) libwiringPiDev.so .c.o: $Q echo [Compile] $< @@ -93,7 +94,7 @@ install: $(DYNAMIC) $Q echo "[Install Dynamic Lib]" $Q install -m 0755 -d $(DESTDIR)$(PREFIX)/lib $Q install -m 0755 libwiringPiDev.so.$(VERSION) $(DESTDIR)$(PREFIX)/lib/libwiringPiDev.so.$(VERSION) - $Q ln -sf $(DESTDIR)$(PREFIX)/lib/libwiringPiDev.so.$(VERSION) $(DESTDIR)/lib/libwiringPiDev.so + $Q ln -sf libwiringPiDev.so.$(VERSION) $(DESTDIR)$(PREFIX)/lib/libwiringPiDev.so $Q $(LDCONFIG) .PHONY: install-static diff --git a/gpio/Makefile b/gpio/Makefile index 7dcd090..dc4be72 100644 --- a/gpio/Makefile +++ b/gpio/Makefile @@ -32,11 +32,11 @@ endif #DEBUG = -g -O0 DEBUG = -O2 -CC = gcc -INCLUDE = -I$(DESTDIR)$(PREFIX)/include -CFLAGS = $(DEBUG) -Wall $(INCLUDE) -Winline -pipe +CC ?= gcc +INCLUDE = -I../wiringPi -I../devLib +CFLAGS += $(DEBUG) -Wall $(INCLUDE) -Winline -pipe -LDFLAGS = -L$(DESTDIR)$(PREFIX)/lib +LDFLAGS = -L../wiringPi -L../devLib LIBS = -lwiringPi -lwiringPiDev -lpthread # May not need to alter anything below this line @@ -52,9 +52,13 @@ version.h: ../VERSION $Q echo Need to run newVersion above. gpio: $(OBJ) - $Q echo [Link] + $Q echo "[Link (Dynamic)]" $Q $(CC) -o $@ $(OBJ) $(LDFLAGS) $(LIBS) +gpio-static: $(OBJ) + $Q echo "[Link (Static)]" + $Q $(CC) -static -o gpio $(OBJ) ../wiringPi/libwiringPi.a ../devLib/libwiringPiDev.a -lpthread + .c.o: $Q echo [Compile] $< $Q $(CC) -c $(CFLAGS) $< -o $@ diff --git a/wiringPi/Makefile b/wiringPi/Makefile index acb6e58..8b84dc6 100644 --- a/wiringPi/Makefile +++ b/wiringPi/Makefile @@ -36,10 +36,10 @@ DYNAMIC=libwiringPi.so.$(VERSION) #DEBUG = -g -O0 DEBUG = -O2 -CC = gcc +CC ?= gcc INCLUDE = -I.
