[yocto] [EXTERNAL] Re: Missing dependencies in recipe-sysroot

[Georgi Georgiev]

Thank you Ross,
Compilation issues are gone...Only one DEPENDS appeared to be enough :-). Thank you again
But can give me a hand to the following because now I have QA issues during my "corrupted" makefile. Is there any way to pass this --sysroot=/<full path>/recipe-sysroot before -L/usr/lib. Eg somehow the whole path to be like -L/<full path>/recipe-sysroot/usr/lib in my makefile. gcc actually follows --sysroot  and /usr/include is to target sysroot...but one annoying warning appear and now this is my last issue.
cc1: warning: include location "/usr/include" is unsafe for cross-compilation [-Wpoison-system-directories]
QA stage (do_package_qa) does not pass. 
Here is my "corrupted" makefile:

# we will use env from poky CC := arm-linux-gnueabihf-gcc
CFLAGS := -g -Wall -fpic
RM = rm -f $(DEPDIR)/*.d $(OBJDIR)/*.o *~ $(OUTPUT)
DEPDIR := dep
OBJDIR := obj
OUTPUT := libanybus-m40.so.0.0.1

LOCAL_SRC_DIRS := .
LOCAL_SRC_DIRS += abcc_adapt
LOCAL_SRC_DIRS += abcc_drv/src
LOCAL_SRC_DIRS += abcc_drv/src/par
LOCAL_SRC_DIRS += abcc_drv/src/par30
LOCAL_SRC_DIRS += abcc_drv/src/serial
LOCAL_SRC_DIRS += abcc_drv/src/spi

LOCAL_INC_DIRS := .
LOCAL_INC_DIRS += abcc_abp
LOCAL_INC_DIRS += abcc_adapt

LOCAL_INC_DIRS += abcc_drv/src/par30
LOCAL_INC_DIRS += abcc_drv/src/serial
LOCAL_INC_DIRS += abcc_drv/src/spi
LOCAL_INC_DIRS += /usr/include

SRC := $(foreach sdir,$(LOCAL_SRC_DIRS),$(wildcard $(sdir)/*.c))
INC := $(foreach idir,$(LOCAL_INC_DIRS),-I$(idir))
LIB := -L/usr/lib
LDFLAGS := -lgpiod -shared -fPIC -Wl,-soname,libanybus-m40.so.0
OBJ := $(addprefix $(OBJDIR)/,$(notdir $(SRC:.c=.o)))
DEP := $(addprefix $(DEPDIR)/,$(notdir $(OBJ:.o=.d)))

VPATH = $(LOCAL_SRC_DIRS)

ifneq "$(findstring clean,$(MAKECMDGOALS))" "clean"
-include $(DEP)
endif

.PHONY: all clean dirtree
.DEFAULT_GOAL := all

all: $(OUTPUT)

$(OUTPUT): $(OBJ)
	$(CC) $(LDFLAGS) -o $@ $(LIB) $^

$(DEPDIR)/%.d: %.c
	$(CC) $(LIB) -MM -MF $@ -MP -MT "$(OBJDIR)/$*.o $@" $(CFLAGS) $(INC) $< 


$(OBJDIR)/%.o: %.c
	$(CC) $(LIB) $(CFLAGS) $(INC) -c -o $@ $< 

$(OBJ) $(DEP): | dirtree

	mkdir -p $(DEPDIR) $(OBJDIR)

Cordially,

We've already gone through this on SO but I'll copy/paste here.

DEPENDS = "libgpiod".  RDEPENDS will build libgpiod at some point, but it won't be in the sysroot for compilation.  Before recipe-specific-sysroots this would mean it *might* be present, now it reliably won't.

The problem is the -L/usr/lib, which presumably should be where libgpiod is.  The makefile is broken, or possibly some tooling that the makefile is calling.  As you haven't shared the makefile we can't help further.
