I am new in Linux. Currently I am working in porting of Sipxtapi (http://sipxtapi.sipfoundry.org/wiki/SipXtapi) on Xilinx arm with platform linux.
Sipxtapi is an open source for SIP-based user agents. It contains following six libraries
(1) sipXportLib
(2) sipXsdpLib
(3) sipxtacklib
(4) sipxmediaLib
(5) sipxmediainterfaceLib
(6) sipXcalllib
(7) sipxtapilib

I am able to port it on linux (having intel) using the instructions given over here https://code.google.com/p/sipxtapi/wiki/Compilation.

for example : in order to build sipXportlib I have the do the following

cd sipXportLib
dos2unix configure.ac
autoreconf -fi
./configure --prefix=/tmp/stage
make;make install
cd ..

But I try to follow the same instructions on Xilinx arm, while executing ./configure --prefix=/tmp/stage, i am getting following errors

I am failing to understand this. Either it is related to arm or something or I need to modify something in configure.ac which is related to arm
Also is configure.ac related to hardware?
I am completely a begginner and completely stuck over here.
Kindly help to solve this issue

A question
"dos2unix configure.ac"

dos2unix ???

did you edit the M4 macro files like the autotools configure config file(configure.ac) on a windows OS ?

editing linux files on a windows Operating system is NOT recommended

Are the other autotools macro files also present in the build folder ?

and what is on line 1512 of the generated "configure" file
./configure: line 1512:


the autools m4 macros are hardware dependent and system dependent


also what compiler are you using on both and what versions are they
code wrote for gcc 4.1 will not likely build with gcc 4.8

It looks like you're missing a necessary header file from a certain library that supplies as_fn_set_status function, or an alias to it. Or, as_fn_set_status could be a function that is supplied but it is calling a program that is not in the path. config.log is the log from the config program. You can look in it to find what's going on. The build tools, or tool-chain, is a little different from architecture to architecture, because the processors on different platforms use unique commands.

ARM, which is RISC ( Reduced Instruction Set Computing ) uses certain compiler-based optimizations that CISC ( Complex Instruction Set Computing ), i.e. Intel processors, do not use. So, I guess config.ac is tool-chain dependent and the tool chain is platform dependent.
