[manjunathjoshi]

Hello all,

Steps followed:

$ vi hello.c

$ source /opt/poky/1.7.1/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi

Can anyone tell me what's the problem here.

pga@pga-ThinkCentre-A85:~/helloworld$ arm-poky-linux-gnueabi-gcc -o hello hello.c

hello.c:1:18: fatal error: stdio.h: No such file or directory

#include<stdio.h>

                  ^

compilation terminated.

pga@pga-ThinkCentre-A85:~/helloworld$ arm-poky-linux-gnueabi-gcc -v

This means i have gcc. I am fed up of this. Please anyone reply.

Hello Manju,

I had the same problem and as far as I could find out, compilation works with

a) using the hard-float compiler option (-mfloat-abi=hard) or

b) invoking the compiler using

$CC <c-file>

Hope this helps...

Kind regards,

Markus

Hello Markus ,

Thanks for your reply. It seems that compiling step

$ arm-poky***-gcc -o hello hello.c

doesn't work and making hard float is not recommended as far as i know.

One needs to follow what autotools do in order to effectively compile helloworld or any other c file.

So

1. $ source /opt/poky/1.7.1/environment****

2. make a directory helloworld .

3. make a hello.c, makefile.am, configure.in or configure.ac

4. $ aclocal

5. $ autoconf

6. $ automake -a

7. $ ./configure ${CONFIGURE_FLAGS}

8. $ make

are the steps that i followed to make things work.

This link might be of help.

Once again thanks Markus. You may follow the link or the steps and then see if it works.

With best regards,

Manju
