Cross-compilier STL libraries mismatch?

[dnt]

I'm running a ReadyNas Duo with 4.1.4 firmware and having hard to track down problems (bus error) when cross-compiling code with shared libraries. When I compile code directly on the NAS, I don't have any problems. What I've noticed is that the gcc/g++ libraries on the NAS have different sizes than the libraries included in the 3.3.5 cross-compiler. Is there an updated cross-compilier that uses the latest gcc/g++ libraries or is there a way I can install the older libraries and headers without copying them manually (the directory structure is different and I'm likely to make a mistake)?

edit: replaced "STL" with "gcc/g++"

Are you talking about the libstdc++ library? What happens if you do a static link?

Thanks for repsonding. Static linking seems to work fine.

I didn't meant to imply that this only affects STL libraries; I just noticed that I had weird problems when compling code with a call to STL. I think this affects all of the gcc/g++ libraries. I also don't understand the inconsistency in library sizes (for example, I know that libm-2.3.2.so is 530xxx bytes in the cross-compiler package and 527xxx bytes on the NAS).

We actually do all our compiling natively, so we don't use the cross compiler. It is supplied for convenience, but it was built with stock libraries and they haven't been updated. However, I am have compiled some dynamically-linked C++ programs before with that compiler, and they worked fine.

Skywalker,

This is good to know!

I had some success running cross-compiled simple programs with shared libraries too; but unfortunately this is not always work, especially with more complex programs (e.g. ffmpeg and apache modules).

Is getting an updated cross-compiler out of the question?

Thanks,

An updated (and more comprehensive) cross compiler toolchain would very much be appreciated. I have been able to cross compile and run some basic programs but have been unable to do much more advanced (e.g. anything that needs a shared lib like ssl, see viewtopic.php?f=35&t=22192)

It would probably be a while from now. But, all the source code is widely available in case somebody wants to take up the project.

you cant

he would have to move the referenced post into a public forum or link the stuff directly here.

or i just do that.

here is what he wanted to show you:

Until it gets posted on the NETGEAR.com GPL page, you can grab it from here:

RNDP6xxx_4.2.1_WW_src.zip (x86 platform; Pro)
RNR4_RND4_RND2_4.1.4_WW_src.zip (Sparc platform; Duo,NV+,1100)

Exellent. Been wondering for some time when there would be updated GPL sources posted at the Netgear site..

The 4.1.4 sources have found their way to the official netgear site since a couple of days.
