 Posted: Wed Aug 22, 2012 3:00 pm Post subject: Raspberry Pi Crossdev Binary Issue |
 |
|
Hello. This is my first post on the forum, but I have been lurking for quite a bit. I am a new Gentoo user, and have recently gotten Gentoo up and running on my desktop as well as my Raspberry Pi (via a disk image). I also emerged crossdev and set up a server so that my Raspberry Pi could access the compiled binaries.
The issue is that even though the Raspberry Pi is able to emerge the binaries, they do not work. I get an error when I run the program: "Command Not Found: /bin/[package I installed]"
The binary is clearly installed, and from reading around it implies that it was compiled incorrectly. When I compare the two emerges for a simple package with no dependencies (nbench) they are the exact same, USE flags and everything, except that the crossdev does not have anything following LINKFLAGS= .
Any thoughts? |

Yep. Can you run ldd on that binary. Maybe it needs /lib/ld-linux-armhf.so.3 which is not present on the distro you use.
Which distribution are you using on the Raspy? And what versions of the cross toolchain are you using?

My crossdev environment is armv6j-hardfloat-linux-gnueabi. I have it set so if gets the stable ARM packages.
ldd does not work for some reason. Even though the binary is definitely there, I get:

crossdev make.conf:

P.S. I also found this discussion about ld-linux-armhf.so.3: http://sources.redhat.com/ml/libc-ports/2012-05/msg00010.html, but I am not entirely sure what they are talking about. |

Ranvier,
Pacages build on th ePi and Packages built with crossdev call the ld by different names.
| Code: | -rwxr-xr-x 1 root root 130148 Aug 17 21:36 ld-2.15.so
lrwxrwxrwx 1 root root 10 Aug 17 21:36 ld-linux-armhf.so.3 -> ld-2.15.so
lrwxrwxrwx 1 root root 19 Aug 17 21:36 ld-linux.so.3 -> ld-linux-armhf.so.3 |
You need both symlinks. Hmm, that s a mess, they should both point to the real ld-2.15.so
