[Buildroot] error toolchain build for mips-linux-uclibc with BR2_INSTALL_LIBSTDCPP

[Buildroot] error toolchain build for mips-linux-uclibc with BR2_INSTALL_LIBSTDCPP

[chinna obireddy]

Hi,

I have already built the tool chain for mips with gcc 4.3.3 and have been
using from some time. Now we got a request to build an application which
needs g++ compiler for same build.

I have enabled BR2_INSTALL_LIBSTDCPP option in .config file and tried to
build the toolchain I have received the following error:

*cp: cannot stat
`/Reddy/11n_Build/Test/dev_main/build/gcc-4.3.3/build_mips/staging_dir/usr/mips-linux-uclibc/lib*/libstdc++.so*':
No such file or directory*
*
*
I have seen posts on this issue online but couldn't find any solution.
*
*
Thank you in advance,
Reddy.

I am not sure what you are using, but looking at this path, it seems
like it is definitely not a recent Buildroot version.

Could you please specify which Buildroot version you're using, and
your .config file? Note that if you're using an ancient Buildroot
version, it's unlikely that we will do anything besides suggesting you
to upgrade to a modern version.

Best regards,

Thomas

Sorry, but you did not attach the configuration file nor you said which
Buildroot version you are using. Well, you did both in a private e-mail
to me, but never sent those informations to the list.

Can you try with a more recent Buildroot version? It's very unlikely
that the community will be interested in fixing problems on such an old
version, especially since we have done a lot of changes and
improvements in Buildroot over the last few years, so 2009.08 is quite
radically different from 2012.02 that we would recommend to use.

Best regards,

Thomas,

Yeah absolutely correct, but I think it needs more time to test the 
whole build and applications running on it again.

Anyhow when I was goggling, found a patch 
http://git.buildroot.net/buildroot/commit/?id=6b578c8d73b6403e3be8bddf611fb1059d7c2f4b 
which is more related to this issue. Will try this and come back.

Last option is to try a new build root.

Regards,
Reddy.

Sure.

It's unlikely. It just shuffles options around, but does not do any
real change to the build logic.

 Did you do a clean rebuild?

 Buildroot doesn't detect when you have changed the toolchain options,
so it may "forget" to perform some build steps (e.g. compiling the C++
library).

 Arnout
