Hi, The first thing to do is to ensure that you have the cross-toolchain (cross compiler, cross linker, cross binutils, cross libc) installed. In the majority case, you cannot use the default gcc in your Linux development PC (assuming you are using an x86-based PC) because it doesn't support ARM9 architecture by default. I assume that you have the cross-toolchain installed correctly, and the toolchain installation directory is /opt/linux/arm9-linux/, then you can cross-compile using the autoconf configure script. If you haven't try it, give it a try. What you have to invoke in the Pjsip source code root directory is something similar to this (I don't know for sure the "triplet" of your cross-toochain, so adapt the parameters as needed): ./configure CC=arm-linux-gnu-gcc --host=arm-linux-gnu --build=i686-linux --with-li b-path=/opt/linux/arm9-linux/lib LDFLAGS='-Wl,-elf2flt' CFLAGS=-O2 make dep && make I think that you don't need to configure the setting manually because autoconf will figure out the compilation parameters as needed. If you still have problems, please don't hesitate to ask. Configuring build.mak pehaps is a little trickier than trying to use autconf configure script ;-) Regards, Darmawan On Jan 22, 2008 5:08 PM, chethana hegde <hegdechethana at yahoo.com> wrote: > Hi, > I am trying to crosscompile pjsip for ARM9 ( Linux 2.6.19). > I have downloaded the latest SVN-version. > > This is the build.mak i am using > > export MACHINE_NAME := arm > export OS_NAME := auto > export HOST_NAME := unix > export CC_NAME := gcc > export TARGET_NAME := arm-unknown-linux > export CROSS_COMPILE := arm-linux-gnu- > export LINUX_POLL := select > > Since i am using OS_NAME=auto, os_auto.h and m_auto.h are created in > pjlib/include/pj/compat , but none of the macros are defined ..... > here is the os_auto.h file... > > /**********************************************************************************************************/ > #ifndef __PJ_COMPAT_OS_AUTO_H__ > #define __PJ_COMPAT_OS_AUTO_H__ > /** > * @file os_auto.h > * @brief Describes operating system specifics (automatically detected by > * autoconf) > */ > /* Canonical OS name */ > /* #undef PJ_OS_NAME */ > /* Legacy macros */ > /* #undef PJ_WIN32 */ > /* #undef PJ_WIN32_WINNT */ > /* #undef WIN32_LEAN_AND_MEAN */ > /* #undef PJ_DARWINOS */ > /* #undef PJ_LINUX */ > /* #undef PJ_RTEMS */ > /* #undef PJ_SUNOS */ > #if defined(PJ_WIN32_WINNT) && !defined(_WIN32_WINNT) > # define _WIN32_WINNT PJ_WIN32_WINNT > #endif > /* Headers availability */ > /* #undef PJ_HAS_ARPA_INET_H */ > /* #undef PJ_HAS_ASSERT_H */ > /* #undef PJ_HAS_CTYPE_H */ > /* #undef PJ_HAS_ERRNO_H */ > /* #undef PJ_HAS_LINUX_SOCKET_H */ > /* #undef PJ_HAS_MALLOC_H */ > /* #undef PJ_HAS_NETDB_H */ > /* #undef PJ_HAS_NETINET_IN_H */ > /* #undef PJ_HAS_NETINET_IP_H */ > /* #undef PJ_HAS_NET_IF_H */ > /* #undef PJ_HAS_IFADDRS_H */ > /* #undef PJ_HAS_SETJMP_H */ > /* #undef PJ_HAS_STDARG_H */ > /* #undef PJ_HAS_STDDEF_H */ > /* #undef PJ_HAS_STDIO_H */ > /* #undef PJ_HAS_STDLIB_H */ > /* #undef PJ_HAS_STRING_H */ > /* #undef PJ_HAS_SYS_IOCTL_H */ > /* #undef PJ_HAS_SYS_SELECT_H */ > /* #undef PJ_HAS_SYS_SOCKET_H */ > /* #undef PJ_HAS_SYS_TIME_H */ > /* #undef PJ_HAS_SYS_TIMEB_H */ > /* #undef PJ_HAS_SYS_TYPES_H */ > /* #undef PJ_HAS_TIME_H */ > /* #undef PJ_HAS_UNISTD_H */ > /* #undef PJ_HAS_MSWSOCK_H */ > /* #undef PJ_HAS_WINSOCK_H */ > /* #undef PJ_HAS_WINSOCK2_H */ > /* #undef PJ_SOCK_HAS_INET_ATON */ > /* #undef PJ_SOCK_HAS_INET_PTON */ > /* #undef PJ_SOCK_HAS_INET_NTOP */ > /* #undef PJ_SOCK_HAS_GETADDRINFO */ > /* Set 1 if native sockaddr_in has sin_len member. > * Default: 0 > */ > /* #undef PJ_SOCKADDR_HAS_LEN */ > /* Does the OS have socklen_t?
