[SOLVED] cross-avr/gcc-4.9.3 fails to emerge

[Oniryczny]

Code: Select all

 * ERROR: cross-avr/gcc-4.9.3::local failed (compile phase):
 *   emake failed

log is over 22MB, what should I present?

because jobs runs in parallel, when one error is report, other jobs are still unaware it has happen until they finish, as soon as a new job is trying to start, it is aware of the error and report failure.

so reporting last error is not of any use, all errors next to error 1 are happening because of error 1.

to answer your question: show the part that lead to your log exposing "Error 1"
but also header of the log, it will tells anyone infos about flags and options in use.

I'm sorry but I donot understand what do you mean telling me to show the part that leads to my log exposing "Error 1"

now even crossdev -t avr fails

What's the output of gcc-config -l ?

[krinn]

I'm sorry but I donot understand what do you mean telling me to show the part that leads to my log exposing "Error 1"
make[1]: *** [configure-target-libvtv] Error 1

I mean this line that show "Error 1" and few lines previous that one. So all good.

If you get C compiler cannot create... It's because the c compiler return an error.
There's plenty reasons why, but the top reason is that because you've made an error in your C/CXXFLAGS.

Hi,
I got the same error as you. I am almost sure it is caused from the addition of the

Code: Select all

openmp and vtv

USE flags. Considering that the error is in a file from the vtv library, I think that the vtv library causes the error. And as you wrote, I checked the USE flags of my gcc compiler. And vtv is a flag with which I have compiled my gcc.

So, what could be another sources of error, then?

Thank you in advance!!!

[Oniryczny]

error in C/CXXFLAGS?
but i had it working in the past

Code: Select all

# gcc-config -l
 [1] avr-4.9.3

 [2] x86_64-pc-linux-gnu-4.9.3 *
#

[Oniryczny]

adding

• -vtv

to USE flags made cross-avr/gcc-5.3.0 successfully emerged
