Compiling and packaging libraries

Compiling and packaging libraries

Hi
I wrote a recipe for adding a library to my image it compile correctly but I have issues in installing it and I got "-dev package contains non-symlink .so" error.
I know default method for install libraries is versioned mode and I need to make symbolic links, but I don't know how?
Another question is what is difference between -dev and -dbg output?

in library's build system you want to use symbol versioning during 
linker stage. Then you can create using ln cmd to creating symlink to 
lib.so and lib.so.<major_version> see [1]

dev packages contain, development headers and libraries which are useful 
for building packages on target

dbg packages contain debug info, which is useful if you are debugging on 
target.

The simplest solution is to use autotools or Cmake for your project. That will 
automatically "do the right thing" to get the library properly installed and 
registered.

Even if your project is just one C file and a header, putting that in 
autotools or cmake is less work than getting all the nitty bits in a 
hand-crafted Makefile right.
