stunnel compiling error

[kmeng1219]

Any suggestion with the stunnel compiling error?

ERROR: stunnel-5.69-r0 do_prepare_recipe_sysroot: The file /usr/include/rpcsvc/nis_object.x is installed by both external-linaro-toolchain and libnsl2, aborting
ERROR: stunnel-5.69-r0 do_prepare_recipe_sysroot:
ERROR: stunnel-5.69-r0 do_prepare_recipe_sysroot: Function failed: extend_recipe_sysroot

My project root directory has the following folders:
meta-linaro meta-openembedded meta-qt5 meta-security meta-tegra meta-tx2 poky

libnsl2 is in poky folder.

I think its best to look at external toolchain you are using. if it should be a provider for libnsl2 then mark the external toolchain to provide it and then prefer it over system libnsl2 so dependent packages can use one copy/provider of this dependency. You can also delete these files from external toolchain recipe so that it can not conflict with system.

@kraj Thank you so much for your response. Yes there is some conflict between libnsl2 in stunnel (meta-openembedded) and libnsl in external-linaro-toolchain.bb (meta-linara)

Remove the libnsl2 dependency in stunnel may pass the compile. This is definitely not good solution for sure. Any other solution? Is it a way to let stunnel to use libnsl from meta-openembedded? I am not very familier with the bitbake.

I think removing dep is ok in a bbppend in your own layer. Or perhaps modify external toolchain recipe to remove the libnsl2 provided files in do_install

Thanks, Kraj. I will add bbappend to fix the conflict.
