Those 'depends on' and 'select' are actual keywords used in *.in files
or just a description?

It is a bit hard to tell without seeing actutal code, but from description
above I guess you created circular dependency which got dropped.

You can use precompiled toolchains from http://debian.pengutronix.de/
… follow the instructions on that site to install.

[ptxdist] pkg-config-wrapper issue

[Richard OGrady]

Hello,

We are using ptxdist 2022.07 and are building 2 packages, libimxvpuapi2 and 
libimxdmabuffer.
libimxvpuapi2 depends on libimxdmabuffer and accordingly libimxvpuapi2.in 
selects libimxdmabuffer.

The libimxvpuapi2 build fails during config.  The config file shows

Checking for 'libimxdmabuffer >= 0.9.0'
['/home/rich/imx6_3D104X_fsl6/Grayhill-iMX6/platform-3D50_std/sysroot-cross/bin/pkg-config',
 '--cflags', '--libs', 'libimxdmabuffer', '>=', '0.9.0']
err: pkg-config: warning: blocking 'libimxdmabuffer': not selected by 
'libimxvpuapi2'

So pkg-config-wrapper is blocking the libimxdmabuffer package.  The code that 
does this in pkg-config-wrapper is:

for pkg in ${pkgs}; do
   if [[ ! " ${whitelist} " =~ " ${pkg} " && ! "${pkg}" =~ 
'-uninstalled' ]]; then
  echo "$(basename ${0}): warning: blocking '${pkg}': not selected 
by '${PKGCONFIG_WHITELIST_SRC}'" >&${ERROR_FD}
  exit 1
   fi
   done

We can get rid of the issue by commenting out the code above in 
pkg-config-wrapper but it seems that then breaks some other packages.
Libimxdmabuffer is version 1.1.2.  Both packages are using waf to build.

What could be going wrong?
