Support for Debian based distros ?!

[martin-g]

Hi,

Is KAE supported for Debian based distros ? Because the README seems to be about RedHat based ones.

I've tried to install it on Ubuntu 18.04.4 LTS aarch64 with the following changes:

I was not able to finish the setup because I've installed OpenSSL in a custom path, so that it does not override the one installed from Ubuntu packages, but now I face some linking errors. I'll report here if I face any issues with KAE!

These messages indicate that you have not installed the License for Kunpeng Accelerator. To get more information about How to install the License, please refer the follow location at
https://bbs.huaweicloud.com/forum/forum.php?mod=viewthread&tid=34245&page=1&extra=#pid105027

In addition, since your OpenSSL is a custom installation, you need to specify the OpenSSL installation path when compiling KAE.
The --openssl_path can be used with the ./configure command to specify the OpenSSL location.

cd KAE
./configure --openssl_path=/usr/local/youropenssl/lib
make
make install

I see. It would be nice to add this info to the README..

The --openssl_path can be used with the ./configure command to specify the OpenSSL location.

Yes, I've done this. Same for warpdriver.

Still I am doing something wrong because it links to the global libssl.so:

ubuntu@ubuntu ~/g/K/openssl-build> ./bin/openssl --help
./bin/openssl: relocation error: ./bin/openssl: symbol EVP_mdc2 version OPENSSL_1_1_0 not defined in file libcrypto.so.1.1 with link time reference

	libdl.so.2 => /lib/aarch64-linux-gnu/libdl.so.2 (0x0000ffff9e2dc000)

not to the one in the custom build:

Due to the license issue I won't be able to continue testing this on Ubuntu. I am doing it out of curiosity. Feel free to close this issue!

Thank you!

This problem is because the OpenSSL you installed does not link to the correct dynamic library at runtime, please reinstall your OpenSSL via ./config -Wl, -rpath=/your/custom/path/ . If symbol EVP_mdc2 not defined still occurs, please upgrade OpenSSL to version 1.1.1a or later

[martin-g]

I use 1.1.1d.
Until now I was using: ./config --prefix=/home/ubuntu/git/KAE/openssl-build --openssldir=/home/ubuntu/git/KAE/openssl-build.

With

./config --prefix=/home/ubuntu/git/KAE/openssl-build --openssldir=/home/ubuntu/git/KAE/openssl-build -Wl,-rpath=/home/ubuntu/git/KAE/openssl-build

it is still the same:

buntu@ubuntu ~/g/K/o/bin> pwd
/home/ubuntu/git/KAE/openssl-build/bin
ubuntu@ubuntu ~/g/K/o/bin> ldd openssl 
	linux-vdso.so.1 (0x0000ffffbeebf000)

	libcrypto.so.1.1 => /usr/lib/aarch64-linux-gnu/libcrypto.so.1.1 (0x0000ffffbeb07000)
	libpthread.so.0 => /lib/aarch64-linux-gnu/libpthread.so.0 (0x0000ffffbeadb000)

	/lib/ld-linux-aarch64.so.1 (0x0000ffffbee94000)
	libdl.so.2 => /lib/aarch64-linux-gnu/libdl.so.2 (0x0000ffffbe96d000)

I will read carefully OpenSSL's INSTALL file in the coming evenings to see what I do wrong.

[mystery-nobody]

-Wl, -rpath should specify the correct location of OpenSSL libcrypto.so， please try the config as follow:
-Wl,-rpath=/home/ubuntu/git/KAE/openssl-build/lib

[martin-g]

This fixed it! Thank you!
