Hello benny, I am using ARM9 Processor with kernel 2.6.19 version I actually followed the steps u had given for MIPS Architcture on Linux(Endianness related) for my ARM Processor I cross compiled using: CC=arm-linux-gnu-gcc ./configure --target=arm --host=arm with the following Build.mak export MACHINE_NAME := arm export OS_NAME := auto export HOST_NAME := unix export CC_NAME := gcc export TARGET_NAME := arm-unknown-none export CROSS_COMPILE := arm-linux-gnu- export LINUX_POLL := select ARM processor config is added to config.h as follows: #elif defined (PJ_M_ARMV4)&& PJ_M_ARMV4 != 0 # include <pj/compat/m_armv4.h> Now without commenting PA_VALIDATE_ENDIANNES iam able to run pjsua properly but iam getting error during making a call: 00:41:53.999 os_core_unix.c pjlib 0.7.0 for POSIX initialized 00:41:54.000 sip_endpoint.c Creating endpoint instance... 00:41:54.016 pjlib select() I/O Queue created (0x1251ac) 00:41:54.017 sip_endpoint.c Module "mod-msg-print" registered 00:41:54.017 sip_transport.
