[uClibc] [buildroot] gcc-2.95 busybox problem

[Philippe Ney]

Hi all,

For my current embedded project, I use buildroot, uClibc and BusyBox.

For some reason, I have to use gcc-2.95

In this way, I get an old buildroot (rev.9452) from the svn archive.

I had first to make some changes to the 100-uclibc-conf.patch that failed
to apply. I also don't apply the STL patch.

And now I encounter an error when compiling Busybox about
__NR_delete_module that seems not to be defined.

I compile for i386 on an i386 (AMD)

For the project, I need to have an objectiv-C compiler. But as it seems gcc-3.x contain a bug about not exporting functions which make the linking fail.

Then I have to use the 2.95. I use gcc-2.95-3 and the one defined in gcc-2.95...mk file

Did have someone tips about using buildroot and busybox with gcc-2.95.

By the way, everything works well with gcc-3.4.2 ...

Thanks in advance for any help
