make dep: Nothing to be done for 'depend' - ios

Question

I have been trying to compile the PJSIP library for an iOS project which needs SIP. Following this tutorial, I have been able to run the configure-iphone script. The next step would to run the make dep for the dependencies, but sadly it fails bcs of some error, unknown to me. I have also tried to edit the makefile, so it points directly to the file, but I still get the error, so it can find the file.
/Applications/Xcode.app/Contents/Developer/usr/bin/make -f Samples.mak depend
make[2]: Nothing to be done for `depend'.
is the error I get.
The make file:
include ../../build.mak
include $(PJDIR)/build/common.mak
export LIBDIR := ../lib
export BINDIR := ../bin
RULES_MAK := $(PJDIR)/build/rules.mak
SAMPLES_MAK := $(PJDIR)/pjsip-apps/build/Samples.mak

Like I said, I added the SAMPLES_MAK variable, but sadly it didn't help. I also found out which line is giving me the error, it's close to the end of the file $(MAKE) -f $(SAMPLES_MAK) $#.

Answer 1

Use official documentation for building. It works 100% for all current architectures for iOS.

Answer 2

Usually this means you've accidentally (?) created a file or directory named depend in your working directory. So, make sees that file or directory and, since the makefile doesn't list any prerequisites of the depend target, it believe the target is up to date.
This is why generally you declare these types of helper targets to be .PHONY, but apparently that makefile doesn't do this.
