Building new package lnav

For Developers
1

Hello
I try to build lnav (https://lnav.org/) using the ImageBuilder.
It runs on a Ubuntu 20.04.2 LTS and works fine to build an OpenWRT image including my selected packages.
For lnav I created .../package/feeds/packages/lnav/Makefile

  No server. No setup. Still featureful.

$(eval $(call BuildPackage,lnav))

I select lnav in 'make menuconfig' and run 'make'.
This gives me the following error:

What's wrong?

sure it's the same lib ?

I tried +zlib, +libz as well as only +z. Always the same error.

4

There's also libzlib...

5

No success. And +liblibz also does not work.
I guess I have to tell the build system somehow to tell the configure script where it will find the library. But how?

6

shot in the dark here, but have a look to see if the zlib-dev package is being built. I have a feeling it could be the one that providers zlib at build time.

7 
make -j1 packages/lnav/{clean,compile} V=99

You'll be in verbose mode and may get more advice from the error...

I gave up.
After looking through the configure.log I found to problem and 'fixed' it with a manual call to configure.sh.
But later in the process another library, libgpm was missing. Unfortunately that library is not part of OpenWRT!
