That is the problem. The .pc file did not exist. That package is a waf
configure/build/install.
To fix I needed to explicitly add --destdir to the install command. It works
now.
Thank you.

[ptxdist] pkg-config-wrapper
Hello,
Debugging a prepare stage issue so trying to understand this chunk of code in
pkg-config-wrapper.
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
Where does ${whitelist} come from? Have tried to trace this back and best
guess is it may come from ../state/${PKGCONFIG_WHITELIST_SRC}. pkgconfig .
If this is the case, perhaps pkg-config-wrapper can't be used during prepare as
the .pkgconfig file isn't there yet?

'depends on' is just a statement of fact, 'select' is keyword in

I guess another way to ask the question is what is that code chunk in
pkg-config-wrapper trying to do?
It seems that if ${whitelist} were to contain ${pkg} then it would not bail
out. Correct?
If so, then by what mechanism would ${whitelist} contain ${pkg}?

[ptxdist] pkg-config-wrapper issue
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?
