 Posted: Sun Dec 05, 2010 1:50 am Post subject: [SOLVED] I need help with gcc and avr linking... |
 |
|
I am running gcc 4.4.4.
I ran this command
to get the AVR toolchain.
That seemed to go fine.
I navigated to the directory that has the program source code for the AVR.
I then ran make to get this output:

I really don't know much about the file structure of gcc or how it works exactly, I just use it. However, I do know when I see an error, which I have made bold above.
I did a file search for avr5.x in the /usr directory, this is what it found:
| Code: |
/usr/local/atmel/avr/lib/ldscripts/avr5.x
/usr/lib64/binutils/avr/2.20.1/ldscripts/avr5.x
|
What directory should avr5.x be in?
I really don't know what to do about this. I know so little about the workings of gcc...
Thanks!

Oh, I forgot to mention that I have tried to compile several different programs with both "make dfu" and "make" and I always get the same exact error:
| Quote: | | /usr/libexec/gcc/avr/ld: cannot open linker script file ldscripts/avr5.x: No such file or directory |

Ok, for anyone who might happen across this thread with the same problem as I, this was my solution.
Note, this may not be a good idea, but it did work for me. Use at your own peril...
First, locate the avr linker script.
Mine was located here:
| Quote: | | /usr/lib64/binutils/avr/2.20.1/ldscripts/ |
At this point you might be able to use the linker option -L and set it equal to "/usr/lib64/binutils/avr/2.20.1/ldscripts/"
| Quote: | | -L/usr/lib64/binutils/avr/2.20.1/ldscripts/ |
That did not work for me so I did the following...
Next, find the location of the linker program ("ld").
Mine was found here:
| Quote: | | /usr/libexec/gcc/avr/ |
However, that was a symbolic link to here:
| Quote: | | /usr/x86_64-pc-linux-gnu/avr/binutils-bin/2.20.1/ |
Then I created symbolic link of the link script location to the location of my linker program.
| Quote: | | ln -s /usr/lib64/binutils/avr/2.20.1/ldscripts/ /usr/x86_64-pc-linux-gnu/avr/binutils-bin/2.20.1/ |
Now it works!

Thanks! This worked for me (same paths and versions)

This bug is still apparently around... fixed it by doing this today:
Error 1: | Code: | | /usr/libexec/gcc/avr/ld: cannot open linker script file ldscripts/avr5.x: No such file or directory |
Fix 1: | Code: | | ln -s /usr/lib/binutils/avr/2.22/ldscripts /usr/avr/lib/ldscripts |
Error 2: | Code: | | /usr/libexec/gcc/avr/ld: cannot find crtm328p.o: No such file or directory |
Fix 2: | Code: | | ln -s /usr/avr/lib/avr5/crtm328p.o /usr/avr/lib/crtm328p.o |

I've the same problem using crtm168p.o and crtm168.o. The message is
| Code: | | /usr/libexec/gcc/avr/ld: cannot find crtm168.o: No such file or directory |
Is there a way around linking several files? |

I wasn't able to figure out a way around the symlinks. I tried a few things, like adding it to my LD_LIBRARY_PATH, but couldn't get anything to work. Maybe you will have better luck. If you do, be sure to post back! |

| Code: | find /usr -iname avr5.x
/usr/lib/binutils/avr/2.20.1/ldscripts/avr5.x
/usr/lib/binutils/avr/2.21.1/ldscripts/avr5.x
|
So what is this about?
Is this something that binutils ebuild should be installing but isn't ?
A LDPATH that needs setting up
In fact the ldscripts directory is missing!
| Code: | bash-4.2#ls /usr/avr/lib/
avr25 crt86401.o crts4433.o crttn22.o crttn45.o libprintf_min.a
avr3 crtc8534.o crts4434.o crttn2313.o crttn461.o libscanf_flt.a
avr31 crts1200.o crts8515.o crttn24.o crttn84.o libscanf_min.a
avr35 crts2313.o crts8535.o crttn25.o crttn85.o
avr4 crts2323.o crttn11.o crttn261.o crttn861.o
avr5 crts2333.o crttn12.o crttn26.o libc.a
avr51 crts2343.o crttn13.o crttn28.o libm.a
avr6 crts4414.o crttn15.o crttn44.o libprintf_flt.a |
any ideas how this _should_ be set up rather than symlink workarounds?

Those two are broken links, note the directory name is 2.21 instead of 2.20.1
Looks like someone got their ${PN} or whatever variables mixed up in the ebuild.
My guess would be a similar error has prevented the ldscripts getting installed or the LDPATH getting set correctly.

Also the new avr binutils has gone into slot 0 , I think I'm going to remove this version until the ebuild is doing what it should.

Just want to leave a breadcrumb here for others, if they expierience the problem, that the crtm168p.o or an other crt can not be found:
| Code: |
# Workaround for /usr/libexec/gcc/avr/ld: cannot open linker script file ldscripts/avr5.x: No such file or directory
CFLAGS += -L/usr/x86_64-pc-linux-gnu/avr/lib/
# Workaround for /usr/libexec/gcc/avr/ld: crtm168.o: No such file: No such file or directory
CFLAGS += -B/usr/avr/lib/avr5/
|
I've put this into the projekt makefile.
i'm using
avr-gcc-4.5.4
bin-utils 2.20
Host: amd64
Bye
