[ECOS] compilation hello program error

[ECOS] compilation hello program error

[Hong Hsu]

  As couldn't find FAQs of this eCos discuss,  I send the question to you.

I use Redhat Linux kernel 2.4.2 on Intel Pentuim 4.  For installation of 
eCos,  the 
/opt/ecos/ecos-1.3.1/tools/bin:/tools/H-i686-pc-linux-gnu/bin:$PATH
is added to PATH, but I do not have /tools/h-i686-pc-linux-gnu/bin 
directory.  what is supporse to be replaced by this?

Since I plan to use synthetic target, so I choose
#ecosconfig new linux

at this stage what portion of ecos.ecc should be modified?

then I build tree:
#ecosconfig tree

then I created a directory /root/hong/projects/ecos/ecos-work to hold 
hello source code.
#cd /root/projects/ecos/ecos-work

Copy Makefile and hello.c from /opt/ecos/ecos-1.3.1/examples/ to the 
directory.  In Makefile, Change PKG_INSTALL_DIR to 
/root/hong/projects/ecos/ecos-work/install 
and uncomment XCC = i686-pc-linux-gnu-gcc

[root@cheetah < mailto:root@cheetah > ecos-work]# echo $BASE_DIR
/root/hong/projects/ecos/

build hello generaged an error:

[root@cheetah < mailto:root@cheetah > ecos-work]# gcc -g -IBASE_DIR/ecos-work/install/include hello.c -LBASE_DIR/ecos-work/install/lib -Ttarget.ld -nostdlib
/usr/bin/ld: cannot open linker script file target.ld: No such file or directory
collect2: ld returned 1 exit status

I notice that
/root/hong/projects/ecos/ecos-work/install/lib  is empty

What is wrong with my procedure for building a hello program?     Your 
help will be appreciated.

Before you can build an application,you need to build the eCos kernel
library.  Do this in the directory you ran 'ecosconfig tree'in.  Simply
run 'make'in that directory.

Then you can try building your application.

Note: you might want to try using the "build_Makefile" script which
should be in the same directory as the sample 'hello.c' file.

/tools/H-i686-pc-linux-gnu is probably
/opt/ecos/ecos-1.3.1/tools/H-i686-pc-linux-gnu 

Note that eCos 1.3.1 is waaaaaaay old. You'd be better of using the
latest CVS version.

You need to invoke make here.

Remember to use $BASE_DIR, not BASE_DIR.

I wonder which file need to setup i686-pc-linux-gnu-gcc as I got an 
error when compile hello program?  Since there are only two bin and src 
subdirectories in /opt/ecos/ecos-1.3.1/tools/   Is it normal for my 
synthetic target as trying to add /tools/H-i686-pc-linux-gnu/bin to PATH?

make[1]: i686-pc-linux-gnu-gcc: Command not found
make[1]: *** [src/hal_misc.o.d] Error 127

Thanks a lot,
