Installing shared libraries for custom application

Installing shared libraries for custom application

[Fletzer Martin]

[-- Attachment #1: Type: text/plain, Size: 1679 bytes --]

Hello everybody,

I'm already working with Poky for serveral months. Nice tool.

But now I'm not able to install shared libraries of ncurses for a custom image. Namely libform, libmenu, and libpanel.
I always get a "Error: Nothing PROVIDES ..."

I tried to extend my image recipie with IMAGE_INSTALL += "libform".
I also tried libform5 and ncurses-libform.

But libtinfo5 is already installed, because bash depends on it.
If I try to install libtinfo manually with IMAGE_INSTALL, I get the same error as with libform.

How can I install this  shared libraries to a custom image?

Thanks,
Martin

Hi Martin,

 From a quick grep of my recipes directory it seems as though these 
libraries need to be pre-fixed with ncurses. For example:

ncurses-libform

See how that treats you!

'Nothing PROVIDES' means there is no bb recipe that provides the a
dependency, i.e., there is no bb recipe that declares it provides
'libform'. The libform package is generated dynamically from the ncurses
package, so the correct DEPENDS (which denotes a *build-time*
dependency), is 'ncurses'.

If your application links against libform, then this should be
automatically pulled into the image; you can manually add something to a
package run-time dependencies by adding it to the RDEPENDS variable (as
Jack says, in this case that should be 'ncurses-libform'), but you
should only need to do this for a library if the application dlopens it.

I hope this helps,

Tomas

Re: Installing shared libraries for custom application

[Fletzer Martin]

Thank you for the fast response.

I tried again with an unmodified master checkout, building core-image-minimal.
I added RDEPENDS = "ncurses-libform" without success. Bitbake returns Nothing Provides.

Then I added the following line to ncurses.inc:
PACKAGES_DYNAMIC="ncurses-lib*"
I tried it, because other recipes use it.

Now I can install the runtime libraries of ncurses to the image with IMAGE_INSTALL += "ncurses-libform".

Is it right to set PACKAGES_DYNAMIC?

Best regards,
Martin
