Error while building gcc for toolset for RTEMS

Sat Feb 9 03:39:46 UTC 2013

I am replying from my phone and can't check the source but I think that test for the compiler wants to link not just -c and produce a .o.

 Check the section of the configure script where the probe fails. It is just a shell script and fairly easy to see what it is trying to do.

Hi Joel,
I am able to compile with sparc-rtems-4.11 and I think my PATH variable is also working.
But I dunno why configuration file for  "{Build-Dir}/sparc-rtems4.11/c/sis/" is not showing "/opt/rtems-4.11/bin"in it's PATH variables.
I am attaching this config(in which errors are coming) with this mail for your reference.

But the surprised thing is that the same PATH values are recognizable in "{Build-Dir}/sparc-rtems4.11/config.log"  which is generating the above log.

Stupid questions...

Are you doing the echo $PATH in the same window based the configure?

Can you compile a simple empty main() {} with sparc-rtems4.11-gcc?

Is there a more detailed message on config.log?

Hi,
My $PATH is
/opt/rtems-4.11/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

And I do have various binaries in /opt/rtems-4.11/bin like:
sparc-rtems4.11-gcc
sparc-rtems4.11-gcc-4.7.2
sparc-rtems4.11-gcc-ar
sparc-rtems4.11-gcc-nm
sparc-rtems4.11-gcc-ranlib

What do you get to from:
echo $PATH
which sparc-rtems4.11-gcc

No that didn't also work

I checked the path /opt/rtem-4.11 has sparc-rtems4.11-gcc.

Is there might be problem in configuring the rtems project. I first did ./bootstrap from rtems source directory and then configure the rtems and tried to build it.

Thanks

4.11 currently refers to the development head, or master. There is no 4.11 branch at the moment. Try the master branch.

The tools are specific to rtems version, so 4.11 tools will not build rtems 4.10.x

Hi All,
Thanks for all your suggestions. The problem was, library cache was not updated. Now I have successfully built my tool chains for rtems-4.11.
But now I am facing problem in building the RTEMS itself.
I have built my tool set for rtems-4.11 but I am not able to find RTEMS-4.11 source code in git repository and CVS. All I see is that most current version is rtems.4.10.2. So I downloaded the code for rtems-4.10.2 and tried to build it.

 I am configuring the rtems with following command:

 ../rtems-4.10.2/configure --target=sparc-rtems4.11 --enable-rtemsbsp=sis --disable-posix --disable-networking --disable-cxx --prefix=/opt/rtems-4.11

And the error I got when I do make all is following:

configure: error: no acceptable cc found in $PATH
make[2]: *** [sis] Error 1

Actually after getting the error I saw  "{build-dir/sparc-rtems4.11/c/sis/config.log}" and problem was that in PATH: it is not including "/opt/rtems-4.11/bin"  but in "{build-dir/sparc-rtems4.11/c/config.log}" the PATH variable is proper.

And my PATH variable is set to : /opt/rtems-4.11/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

I have looked the previous mails regarding this problem and most common cause of this error was PATH variable but I think my PATH variable is proper. I am not able to figure out why it is happening?

Thanks
Manish

If you continue on the path of building your own tools, the command
"ldconfig -p" is your friend.  This command will show you all the
libraries known and cached.  If you installed a library from source and
don't see it listed, you may need to run "ldconfig" as root to update
the cache.  I've mostly seen this out-of-date ld.so cache problem on
Fedora/CentOS systems but it can't hurt to check.
