SDK does not contain pkg-config files

SDK does not contain pkg-config files

[Mike Looijmans]

I'm trying to get the SDK to work, but no success because the SDK apparently 
does not install any pkg-config file, resulting in autotools and cmake not 
being able to find any library.

Built the SDK using "bitbake -c populate_sdk image"

Install the resulting SDK, and source the shell script.

Building "helloworld" works. Building something slightly more advanced fails, 
because pkg-config isn't working: "pkg-config --list-all" is empty.

The cause is that the pkgconfig files simply aren't in the sysroot:

$ echo $PKG_CONFIG_PATH
/home/mike/p/sysroots/cortexa9t2hf-neon-oe-linux-gnueabi/usr/lib/pkgconfig:/home/mike/p/sysroots/cortexa9t2hf-neon-oe-linux-gnueabi/usr/share/pkgconfig
$ ls /home/mike/p/sysroots/cortexa9t2hf-neon-oe-linux-gnueabi/usr/lib/pkgconfig
ls: cannot access 
'/home/mike/p/sysroots/cortexa9t2hf-neon-oe-linux-gnueabi/usr/lib/pkgconfig': 
No such file or directory
$ ls /home/mike/p/sysroots/cortexa9t2hf-neon-oe-linux-gnueabi/usr/share/pkgconfig
ls: cannot access 
'/home/mike/p/sysroots/cortexa9t2hf-neon-oe-linux-gnueabi/usr/share/pkgconfig': 
No such file or directory

Looks like something went wrong.

My host has minimal -dev packages installed:

$ dpkg -l \*-dev|grep ii
ii  dpkg-dev                  1.19.7            all          Debian 
package development tools
ii  libc6-dev:amd64           2.28-10           amd64        GNU C

ii  libgcc-8-dev:amd64        8.3.0-6           amd64        GCC support

But inside a core-image-minimal SDK:

$ ls sysroots/corei7-64-poky-linux/usr/lib/pkgconfig/ | head

rpm                   RPM - RPM Package Manager

So, works for me?

Well, that's at least good to know.

I'm on the "thud" branch currently, so I hope this isn't something that got 
fixed only recently.

I'll try some simple images first. I gather there's no particular magic 
incantation I need to put into my image recipe to get the pkg-config files 
into the SDK sysroot?

Right, they're just in the -dev packages.  I'd try building a 
core-image-minimal SDK to verify that works, as I suspect you've done 
something in your image to break the SDK.

I think I found it.

The image installs the dropbear SSH server, and the openssh-sftp-server. These 
seem to cause a conflict, and then ALL the "-dev" packages get skipped.

The warning looks like this (I removed some sensitive information and a list 
of a few hundred package names):


WARNING: prolira-delirium-image-1.0-r0 do_populate_sdk: Unable to install 
packages. Command '.../..-image/1.0-r0/recipe-sysroot-native/usr/bin/opkg 
--volatile-cache -f ... --force_postinstall --prefer-arch-to-version   install 
... binutils-dev liblzo2-dev ... libaio-dev' returned 1:
Collected errors:
  * Solver encountered 1 problem(s):
  * Problem 1/1:
  *   - package openssh-dev-7.8p1+git-r0.cortexa9t2hf-neon requires openssh = 
7.8p1+git-r0, but none of the providers can be installed
  *
  * Solution 1:
  *   - allow deinstallation of packagegroup-core-ssh-dropbear-1.0-r1.all

  *   - do not ask to install a package providing dropbear-dev

  *   - do not ask to install a package providing 
packagegroup-core-ssh-dropbear-dev

  * Solution 2:
  *   - do not ask to install a package providing openssh-dev



If I remove "openssh-sftp-server" from the packages, the warning (which should 
have been an error?) disappears and the resulting SDK properly contains all 
the pkg-config files again.

I wonder if there's a proper fix to prevent this, i.e. break the link between 
openssh-sftp-server and openssh-dev.

RDEPENDS_${PN}-dev_remove =  "openssh-sftp-server"

in openssh recipe might be able to do it
