Hi all,

I am having a problem with taking the buildroot process pass the libstdc++ phase. Here is my setup:

buildroot snapshot 2008-01-02

binutils 2.18

kernel   2.6.22.10
gcc      3.4.6
uClibc   0.9.29

Maybe you should try with gcc-4.2.1
Best Regards
Ulf Samuelsson

Thanks for the suggestion to try gcc-4.2.1 but what I would find helpful is to start with a configuration which was successful and created a functional tool for a generic arm, nomad, no FP, soft-float, little-Endean system.

Best Regards,
Port

I have made several attempts to run the buildroot program with target set
to "linux-uclibc" and "linux". It always fails the same way:

For the "linux-uclibc" target there are no *.o files in .libs directory
(but it contains libstdc++.a, libstdc++.la, and libstdc++.lai).

There is a patch which fixes this in the bug-tracker,

Now, if someone with commit access could be so kind .....

Thanks Atle,

This sounds very promising but the solution doesn't seem to be accessible.

Hi,

Check your internet connection settings. I downloaded patch from link provided by Atle successfully. And tell then if this patch fixes your problem.

Hi,

I can download the patch now. There was an ending dot in the link creating the access problem.

Should this patch be stored together with the other gcc 3.4.6 patches?

Thanks,
Piotr

No, apply it to your buildroot source tree. In top dir do:

patch -p1 < gcc-3.4.6-fix-libstc++-pic.patch

#8 lore raw

The buildroot process finished with some error (see below - and I wouldn't mind to know what it means) but the toolchain seems to be all in place.
