Parallella Community

Hi All,

I have built a new SD Image with Linaro following the gudie put up last week,
I have the kickstarter 16 core version with a ZED Board.

I am trying to build the e-sdk by downloading from source on https://github.com/parallella/epiphany-gcc
I am getting the following erros when i built it.
Link for pastebin:

Let me know if someone has already faced similar issue or know of a solution.

Thanks,
Anup.

Hi anupkini,

Just to check, how did you configure gcc, did you use the configure/build scripts from https://github.com/parallella/epiphany-sdk or did you configure yourself (if so what commands did you use. Secondly, do you have all the prerequisites installed as specified in https://github.com/parallella/epiphany- ... g-on-Linux ?

If you didnt use the epiphany-sdk build-toolchain script, can you give that a try and see if it resolves the issue?

Hi Simon,

I was missing Bison, Flex and texinfo.
After installin them through apt-get and restartign the system once, i am stumbling upon this error.

Use a pristine source tree when building in a separate tree


What is a pristine source tree ??
Should i check out something more ??

Thanks,
Anup.

Hi,

Rerun the script with --force on the end, that error is because tools that weren't installed before now are and the build system should start afresh.

Hi Simon,

I tried a few times with --force switch but it would end up with the same error.
I have now downloaded a fresh copy of all the repositories and trying again.

Will get back once done.


Thanks,
Anup.

I just re-read the error, if you run "git clean -fxd" and "git reset --hard" in the gcc repository it should then work. The configure script is complaining that there is an old build in the gcc directory.

Also I have just updated the build-toolchain script so that --force is no longer required.

Hi Simon,

I update the details and the build process ran for about and hour.
I ended with the following out of memory errors !!!

gcc -c -DIN_GCC_FRONTEND -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Wold-style-definition -Wc++-compat -fno-common -DHAVE_CONFIG_H -I. -Icp -I/home/linaro/sdk/../srcw/gcc -I/home/linaro/sdk/../srcw/gcc/cp -I/home/linaro/sdk/../srcw/gcc/../include -I/home/linaro/sdk/../srcw/gcc/../libcpp/include -I/home/linaro/sdk/../srcw/gcc/../libdecnumber -I/home/linaro/sdk/../srcw/gcc/../libdecnumber/dpd -I../libdecnumber /home/linaro/sdk/../srcw/gcc/cp/except.c -o cp/except.o
/home/linaro/sdk/../srcw/gcc/gcc.c: In function ‘get_random_number’:
/home/linaro/sdk/../srcw/gcc/gcc.c:8065:12: warning: ignoring return value of ‘read’, declared with attribute warn_unused_result [-Wunused-result]

Out of memory: Kill process 25361 (cc1) score 51 or sacrifice child

In this case I'd suggest turning off parallelism in the build script (comment out line 82/make_load="....") in build-toolchain.sh . The build will (obviously) take longer this way. If that still doesn't work, you should either close programs not doing anything or create some swap space on the SD card temporarily just for the build. To do the latter, as root:

fallocate -l 1G /tmpswap
mkswap /tmpswap
swapon /tmpswap

Once the build is complete, you can use swapoff on the file and remove it, you shouldn't need it when using the tools.

Hope that helps.

Hi Simon,

Thanks a lot for you guidance and help.
It took about 5 hrs and 30 mins to build the e-gcc and the sdk !!!

I also built the github.com-Adapteva/epiphany-libs and epiphany-sdk. Not sure if this was needed or not

Will start working on the hello world example by Yaniv.

Anup
