Build libimxvpuapi failed with can't find hantro

Hi community:

i met building failure against libimxvpuapi.

My build command is :

./waf configure --sysroot-path=/ --imx-platform=imx8mm

And the output are:

is there any missing or misconfiguration on my Linux host Ubuntu 16.04?

thank you in advanced.

BRs.

Add more information：

1. I tried to build libimxvpuapi on my Linux Host--Linux liubolun-OptiPlex-7040 4.15.0-45-generic #48~16.04.1-Ubuntu SMP Tue Jan 29 18:03:48 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux;

2. the libhantro.so is derived from L4.14.98_2.0.0_ga_images_MX8MMEVK/usr/lib which is download from NXP web;

3. the result of file libhantro.so is:

/usr/lib/libhantro.so: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, BuildID[sha1]=663e023f6f0d5d4eed7e66e214e160b35c59fe97, stripped

4. I copy the libhantro.so and libhantro_h1.so to /usr/lib/ and copy hantro_enc and hantro_dec folder to /usr/include/

Then i run the waf configure command and met the configure failed(ld error)

Any suggestions again this issue?

thank you.

Seemed i find the root cause.

The libhantro.so that is required by libimxvpapi is ARM aarch64, version. But i built libimxvpuapi on Ubuntu 16.04 which request X86 version of this lib.

So is there any method to get the X86 version of this lib?

Or is there anyone else building libimxvpapi on Ubuntu 16.04?

thank you.

Please follow the Yocto user's guide to build the bsp.

hello jimmychan, thank you for you comments.

The fact is that i build yocto by myself.

The libhantro.so that i built out are all ARM aarch64.

The other question is that is there any source code about libhantro?

thank you.

Yes, the BSP is used to build for the i.MX processor which is ARM cores inside.
