Hi,
I am trying to build a working environment with Angstrom Linux, QT5 for
Toradex Apalis iMX6 module and additional QT5 SDK for my host machine.
The compilation of Angstrom with additional QT5 layer went fine.
However, there are some problems when building toolchain for the host
machine (command meta-toolchain-qt5). It seems that there is a problem
with configuration of linaro gcc runtime 4.8.
The reported error is: "checking dynamic linker characteristics...
configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES".
The log file is in the attachment. Does anyone have any idea how to fix
this problem? I am using Ubuntu 14.04.
Thanks in advance,
Crt Gorup
Hello,
I'm trying to perform cross platform remote debugging from my x86 computer
to a remote ARM device. (ex: Beagle Bone Black)
I'm using Ubuntu 14.04 and Eclipse CDT.
I installed the Ubuntu package gcc-arm-linux-gnueabihf but the gdb debugger
is not in that package.
Therefore, I'm wondering if I should use the Linaro toolchain (which
include arm-linux-gnueabihf-gdb) or if I should install the Ubuntu
gdb-multiarch package.
What is the difference between gdb-multiarch and arm-linux-gnueabihf-gdb ?
Is it better to use gdb-multiarch ?
Thanks

is now takes 1/4 of the time it used to for each remote execution test
case. (TCWG 512 - 4/10)

current RSH/SSH support. (TCWG 512 - 3/10)

* TCWG-180 Debugging - LTO bootstrap failure in Aarch64 with GCC 4.9. (6/10)
Tried to recompile object files that showed differences in GCC trunk
on amd64 machine.It turned out that GCC make system always builds LTO
files in “gcc” directory and uses prev-gcc/xg++ to build them.
No differences when building stage2 and stage3 objects under same
directory “gcc” in FSF trunk.
Doing the same experiment with gcc 4.9 branch shows failure both in
x86_64 and aarch64.
Communicated the issue to Richard Beiner. Got some feedback on
debugging from Honza and Richard.
Tried passing –save-temps to BOOT_CFLAGS using FSF trunk, getting
assembler errors. Need to come back to this problem after finding root
cause.
Read about LTO passes and wpa (partitioned ) vs non portioned mode.
* Others (2/10)
* Upstream patch review.
* 1-1 Meeting Christophe.
* Misc and internal meeting.
* setup LLVM.
* Friday off (2/10).
