Have you reproduced the error?

Have you reproduced the issue?

Sorry about the delay. I just found out that the notifications from the forum were not getting sent, so we weren't notified anyone posted. I'm going to try and repoduce your problem, but I have a small backlog so it may take a bit.

I don't get the libtool error, but I do get a different message for a different package. When you switched to the 2.4-4 BSP, did you previously compile 2.4-3 on the same machine?

Try rebuilding libtool with:

./ltib --hostcf -f -p libtool

That still doesn't fix the issue I am seeing, but I am curious to see if that helps you get past that error.

Hello Adam,

> When you switched to the 2.4-4 BSP, did you previously compile 2.4-3 on the same machine?

No, I've compiled binutils from scratch. To reproduce the issue I follow the following steps:

1 - Download the VM SDK from LogicPD (file 1027480_LogicPD_Linux_BSP_2.4-4.ova) and import them to the Virtual Box program.

2 - Boot the new virtual machine and update the VirtualBox guest utils of the virtual machine to version 5.0.24. DO NOT update debian packages like libraries, linux kernel, programs,.... The version of libtool is:

/usr/bin/libtool --help
[...]
host-triplet: x86_64-pc-linux-gnu
shell: /bin/bash
compiler: gcc
compiler flags: -Wall -g -O2
linker: /usr/bin/ld -m elf_x86_64 (gnu? yes)
libtool: (GNU libtool) 2.4.2 Debian-2.4.2-1ubuntu1
automake:
autoconf:

The virtual machine is ready.

BSP 2.4-4 included in the VM

Modify the BSP already included in the VM:

1 - Open a terminal.
2 - Change to BSP dir (cd ~/logic/Logic_BSPs/Linux_3.0/1027480_LogicPD_Linux_BSP_2.4-4)
3 - Execute './ltib -c' to select gcc version 4.6.1 and select 'oprofile' package.

Ltib rebuils all packages because the toolchain has been modified. The compilation of binutils fails:



I've rebuild libtool with the command that you included in the previous message in both BSPs, however the compilation of binutils has failed in both BSPs.

Thanks and Best Regards,
Joaquim Duran

Download BSP 2.4-4

1 - Download the file 1027480_LogicPD_Linux_BSP_2.4-4.tar.bz2 from LogicPD to the VM.
2 - Uncompress the BSP.
3 - Configure the BSP for a Wireless Torpedo module (./ltib -c --preconfig config/platform/omap_logic/defconfig), select gcc 4.6.1 as toolchain and select 'oprofile' package. Exit and save changes.

cc1: all warnings being treated as errors

Reading through the logs, it appears to be caused by the default setting of -Werror.

To disable this compiler flag, modify /home/logic/logic/Logic_BSPs/Linux_3.0/1027480_LogicPD_Linux_BSP_2.4-4/dist/lfs-5.1binutils/binutils.spec

Line 73 needs to add the flag to disable treating errors as warnings. It should be modified to read:

make CC_FOR_BUILD="${BUILDCC}" all CFLAGS="-Wno-error"


This should fix the Binutils error.

I ran into an additional error building oprofile and I found a find (at https://code.google.com/p/android/issues/detail?id=22003)


If you get an error with oprofile, edit

./rpm/BUILD/oprofile-0.9.2/libpp/format_output.h


Line 85 should be modified to read:
counts_t & counts;


From there it should be OK. Let me know if you have any issues.

adam

Adam,

Applying your changes it has been possible to compile oprofile.

Great job!!
