Bug #: 14541
Summary: Wrong entry point computation using cross binutils
linux amd64->arm-linux-gnueabihf
Product: binutils
Version: 2.22
Status: NEW
Severity: normal
Priority: P2
Component: binutils
AssignedTo: unassig...@sourceware.org
ReportedBy: eric.vale...@free.fr
Classification: Unclassified
I'm trying to build a cross compilation tool for raspberry pi on a debian amd64
machine. While I succeeded to build the tools either the debian way or using
pure official gnu tools releases unpatched, in both case I get binary that do
no execute on the raspberry.
Even a simple hello word statically compiled fails to execute
test.c :
#include <stdio.h>
main()
{
printf("hello world\n");
exit (0);
}
I noticed the entry point is wrongly computed on this sample program (native
tools on raspberry have _start address as their entry point not _start +1!
