PJSIP library compile error for iOS Simulator

I am trying to compile pjsip library for iOS, but getting an error and I am following below steps

Step 1: Create a new file config_site.h in the project folder /pjlib/include/pj/ with the following code:

#define PJ_CONFIG_IPHONE 1 
#include <pjconfig_site_sample.h>

Step 2: Open terminal

$ cd /path/to/my/pjsip/dir

Step 3:

export DEVPATH=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer
ARCH="-arch x86_64" CFLAGS="-O2 -m64 -mios-simulator-version-min=5.0" LDFLAGS="-O2 -m64 -mios-simulator-version-min=5.0" ./configure-iphone

Step 4:

make dep && make clean && make

After this command, I am getting the error

for dir in pjlib/build pjlib-util/build pjnath/build third_party/build pjmedia/build pjsip/build pjsip-apps/build ; do \
    if /Library/Developer/CommandLineTools/usr/bin/make  -C $dir dep; then \
        true; \
    else \
        exit 1; \
    fi; \
done
/Library/Developer/CommandLineTools/usr/bin/make -f /Users/murtuza/Desktop/PJSip/iOS/pjproject-2.9/build/rules.mak APP=PJLIB app=pjlib depend
.pjlib-x86_64-apple-darwin_ios.depend:3: *** missing separator.  Stop.
make[1]: *** [depend] Error 2
make: *** [dep] Error 1

Am i missing something or else. Thanks for help

Solution

Refer to https://trac.pjsip.org/repos/wiki/FAQ#missing-sep-err

This happens because of corrupt dependency file, probably because make dep stopped or was stopped abruptly previously. The solution is either to delete the offending file manually or to run make distclean to clean everything. Either case, you'd have to run make dep again to rebuild the dependency.
