When building I get a cryptodev error... about bpi-router-linux

[frank-w]

cryptodev is only available in branch 4.14-main...in other branches just ignore it. in 4.14-main the clear throws also an error if there are no files to remove :)

Which branch do you want to build?

If you do not need cryptodev,just ignore this. It's an additional script and not needed to build the kernel itself so mainscript goes over it

[whalley]

Thanks for quick response, appreciated. My board should arrive in next week or so, I'm just getting prepared :-)

I am actually building 4.14-main (based on this looking like to most compatible build feature-wise) - looks like it the clean throwing the error as you noted.

[frank-w]

If building 4.14-main,the error should be different.

make[1]: *** M=/home/mark/banana-pi/BPI-R2-4.14/cryptodev/cryptodev-linux: No such file or directory. Stop.

The directory itself should exist

https://github.com/frank-w/BPI-R2-4.14/tree/4.14-main/cryptodev/cryptodev-linux

The error should say that files cannot be removed because they does not exist if not previous compiled. But as i said if you do not need cryptodev you can ignore that

[whalley]

Don't think I need the crypto... but it was niggling me....

In the cryptodev/build.sh

should:

make clean
make KERNEL_DIR=$kerneldir CROSS_COMPILE=arm-linux-gnueabihf- ARCH=arm

not be:

make KERNEL_DIR=$kerneldir clean
make KERNEL_DIR=$kerneldir CROSS_COMPILE=arm-linux-gnueabihf- ARCH=arm

This allows me the build it cleanly in the cryptodev directory.

But building the full kernel now gives:

Build CryptoDev
make -C /home/mark/banana-pi/BPI-R2-4.14 M=/home/mark/banana-pi/BPI-R2-4.14/cryptodev/cryptodev-linux ARCH=arm CROSS_COMPILE=ccache arm-linux-gnueabihf- clean

make[1]: Entering directory '/home/mark/banana-pi/BPI-R2-4.14'
  Building modules, stage 2.

I'm not sure why the
ARCH=arm CROSS_COMPILE=ccache arm-linux-gnueabihf-

is being added to the clean in this case!

[frank-w]

my script does not add it

https://github.com/frank-w/BPI-R2-4.14/blob/902d112b8a7cf645e40d2aeeadedc2403dd84aee/cryptodev/build.sh#L7

it seems it is added by Makefile

https://github.com/frank-w/BPI-R2-4.14/blob/902d112b8a7cf645e40d2aeeadedc2403dd84aee/cryptodev/cryptodev-linux/Makefile#L39

but removing this $(KERNEL_MAKE_OPTS) results in an infinite loop

[whalley]

Yes, the Makefile should be:

$(MAKE) -C $(KERNEL_DIR) M=$(CURDIR) clean

That, and the change to the build.sh to add the KERNEL_DIR works. Thanks for the pointer.

[frank-w]

$(MAKE) -C $(KERNEL_DIR) M=$(CURDIR) clean
does also not work...clean seems to treat M=... as dir not as var and tries to access it...

but this Makefile is not modified by me...

https://github.com/cryptodev-linux/cryptodev-linux/blob/f60aa08c63fc02780554a0a12180a478ca27d49f/Makefile#L39

[whalley]

Have you also make the change to cryptodev/build.sh I mentioned above ?

In the cryptodev/build.sh

make clean
make KERNEL_DIR=$kerneldir CROSS_COMPILE=arm-linux-gnueabihf- ARCH=arm

should be:

make KERNEL_DIR=$kerneldir clean
make KERNEL_DIR=$kerneldir CROSS_COMPILE=arm-linux-gnueabihf- ARCH=arm

[frank-w]

right, i only hae to change cryptodev/build.sh and it works if i call it alone....in main build.sh i got the mentioned error where ccache and crosscompiler and concatenated

[whalley]

Yes you need to change the cryptodev-linux Makefile to:

$(MAKE) -C $(KERNEL_DIR) M=$(CURDIR) clean

to fix the errors

[frank-w]

see the last commit...works here...sorry had not pushed it...now you can see it

[whalley]

Yep, all good. Thanks.
