File fix-dev-deps.patch of Package wiringpi
Author: Dave Jones <dave.jones@canonical.com> Description: Fix various dependencies The libwiringPiDev library is missing a link dependency on libwiringPi. It also needs to include the path to the libwiringPi headers. The gpio utility has extraneous lib dependencies (librt, libm, and libcrypt). Finally, for libwiringPi itself, the libraries to link with must be placed at the end of the command line or the linker (with the now default -as-needed option) won't declare the exported nameds in the libraries as needed. --- a/gpio/Makefile +++ b/gpio/Makefile @@ -36,7 +36,7 @@ CFLAGS = $(DEBUG) -Wall -Wextra $(INCLUDE) -Winline -pipe LDFLAGS = -L$(DESTDIR)$(PREFIX)/lib -LIBS = -lwiringPi -lwiringPiDev -lpthread -lrt -lm -lcrypt +LIBS = -lwiringPi -lwiringPiDev -lpthread # May not need to alter anything below this line ############################################################################### --- a/wiringPi/Makefile +++ b/wiringPi/Makefile @@ -74,7 +74,8 @@ $(DYNAMIC): $(OBJ) $Q echo "[Link (Dynamic)]" - $Q $(CC) -shared -Wl,-soname,libwiringPi.so$(WIRINGPI_SONAME_SUFFIX) -o libwiringPi.so.$(VERSION) $(LIBS) $(OBJ) + $Q $(CC) -shared -Wl,-soname,libwiringPi.so$(WIRINGPI_SONAME_SUFFIX) -o libwiringPi.so.$(VERSION) $(OBJ) $(LIBS) + $Q ln -sf libwiringPi.so.$(VERSION) libwiringPi.so .c.o: $Q echo [Compile] $< --- a/devLib/Makefile +++ b/devLib/Makefile @@ -36,11 +36,11 @@ #DEBUG = -g -O0 DEBUG = -O2 -INCLUDE = -I. +INCLUDE = -I. -I../wiringPi DEFS = -D_GNU_SOURCE CFLAGS = $(DEBUG) $(DEFS) -Wformat=2 -Wall -Winline $(INCLUDE) -pipe -fPIC -LIBS = +LIBS = -lpthread -lwiringPi ############################################################################### @@ -67,7 +67,7 @@ $(DYNAMIC): $(OBJ) $Q echo "[Link (Dynamic)]" - $Q $(CC) -shared -Wl,-soname,libwiringPiDev.so$(WIRINGPI_SONAME_SUFFIX) -o libwiringPiDev.so.$(VERSION) -lpthread $(OBJ) + $Q $(CC) -shared -Wl,-soname,libwiringPiDev.so$(WIRINGPI_SONAME_SUFFIX) -o libwiringPiDev.so.$(VERSION) -L ../wiringPi $(OBJ) $(LIBS) .c.o: $Q echo [Compile] $<
