Can't compile for arm host

4ntoine commented 4 years ago

assume using the following:

android-ndk-r21 - standalone toolchain installed with --arch arm --api 21 --install-dir ~/x-tools/arm-ndk-21 and ~/x-tools/arm-ndk-21/bin is added to PATH.
xtensa-lx106-elf compiled locally, installed to ~/x-tools/xtensa-lx106-elf and ~/x-tools/xtensa-lx106-elf/bin is added to PATH
gcc version updated to 9.2.0 (tried 8.3.0 too)
isl version 0.18
cloog version 0.18.4

created "arm-ndk,xtensa-lx106-elf" sample:

and created configuration from it:

./ct-ng arm-ndk,xtensa-lx106-elf

and manually edited .configuration to have the versions above (it seems ./ct-ng overwrote them to default)

It results into the following:

checking for the value of EOF... configure: error: computing EOF failed
make[2]: ** [configure-target-libstdc++-v3] Error 1

CT_TOOLCHAIN_TYPE="cross" seems to be wrong, trying CT_TOOLCHAIN_TYPE="canadian"..

Nope, did not help, still having:

Same error if trying with CT_HOST="arm-unknown-linux-gnueabi" (and toolchain compiled with upstream crosstool-ng, installed and added to PATH)

nolange commented 4 years ago

Dont think this is related to #1188, do a google search on "checking for the value of EOF", I think you have some directories mixed up. look into the config.log in /opt/Espressif/crosstool-NG-android/.build/xtensa-lx106-elf/build/build-cc-final-build-x86_64-build_unknown-linux-gnufor more clues.

4ntoine commented 4 years ago

@nolange i did googled before obviously, but unfortunately at the moment i don't have enough understanding on what's wrong and how to fix it. Will continue, any advice is appreciated

4ntoine commented 4 years ago

hmm, config.log in /opt/Espressif/crosstool-NG-android/.build/xtensa-lx106-elf/build/build-cc-final-build-x86_64-build_unknown-linux-gnu has configure: exit 0, no mentions of "EOF issue" there

Question on SO: https://stackoverflow.com/questions/62457315/how-to-make-canadian-cross-for-xtensa-lx106-elf-for-android-arm-host-with-crosst

jcmvbkbc commented 4 years ago

I've pushed a branch xtensa-1.24.x with a defconfig aarch64-linux-gnu,xtensa-lx106-elf that I used to build a static toolchain for aarch64-linux host, xtensa-lx106-elf target. Please give it a try. It may need more configuration tweaks to match the toolchain built by the esp-open-sdk as I did the simplest config possible from the top of my head just to see if it builds.

4ntoine commented 4 years ago

Hi, @jcmvbkbc. Thanks for looking into it!

I had to change host to "aarch64-linux-android" to use it with standalone toolchain from Android NDK 21b (received it using "./build/tools/make_standalone_toolchain.py --arch arm64 --api 21 --install-dir /home/anton/x-tools/arm64-ndk").

Eventually i get the following:

What toolchain should be used for "aarch64-linux-gnu"? I've tried "./ct-ng aarch64-linux-gnu" but it was not found. Am i missing anything else?

4ntoine commented 4 years ago

Worked for me if compiling with toolchain from the following ubuntu packages (NOT from NDK):

sudo apt install g++-aarch64-linux-gnu
sudo apt install gcc-aarch64-linux-gnu

jcmvbkbc / crosstool-NG

Can't compile for arm host #68
