It worked (somehow, not quite correct, and some packages where not |
11 |
rebuildable) at the time where uClibc had support for LIBGCC_FUNCTIONS |
12 |
(adding functions from libgcc to libc) This was the only way I got a |
13 |
system running it (__guard and __smash... where added to libc). Since then |
14 |
I cannot modify buildroot so that I get a system running, segfaults on all |
15 |
the line (tested only with gcc-3.3.x and protector 3.3-5). I think the |
16 |
solution would be to add the needed functions to uClibc (and remove them |
17 |
from libgcc!!!). |

UPX developer says, that the uncompression does not cost much, didn't |
27 |
really tested it. I do not have cramfs experience. |

The wrappers are for ever gone. Use the procedure from buildroot (the |
38 |
toolchain building from here). |
