Shared libraries

Hello everybody,

I am having major problems at the moment with shared libraries and I have to little knowledge of them to solve them. So please, please help me Smilie

Ok this is the problem:

I have a library A, which uses B and C, and C uses again D.

If I try to run A as plugin in apache, it says C doesn't find D ( unresolved, etc).

I have the suspission that it has to do with the way we make our stuff. We use omake. I can change the compiler "severity" of it, due to a lot of problems I will rather not explain here. The thing is that someone stated it would be enough to put all the -l<lib> options on higher level.

So in my example this would mean that the makefile of libA contains the following options :-lB -lC -lD, and the other makefiles didn't need references to the libs they are using.

But that doesn't seem to work. Lib C still complains about unresolves ( but only runtime!! ), although the file is there and in the LD_LIBRARY_PATH.

Does someone have a good article, or some hints for me, how to compile the .so files so they will run without unresolves? Where should I include the -l options?

Also, x does not... (2 Replies)

netatalk-config(1)					       The Netatalk Project						netatalk-config(1)

NAME
netatalk-config - script to get information about the installed version of netatalk SYNOPSIS
netatalk-config [--prefix[=DIR]] [--exec_prefix[=DIR]] [--help] [--version] [--libs] [--libs-dirs] [--libs-names] [--cflags] [--macros] DESCRIPTION
netatalk-config is a tool that is used to configure to determine the compiler and linker flags that should be used to compile and link pro- grams that use the netatalk run-time libraries. OPTIONS
netatalk-config accepts the following options: --help Print a short help for this command and exit. --version Print the currently installed version of netatalk on the standard output. --libs Print the linker flags that are necessary to link against the netatalk run-time libraries. --libs-dirs Print only the -l/-R part of --libs. --libs-names Print only the -l part of --libs. --cflags Print the compiler flags that are necessary to compile a program linked against the netatalk run-time libraries. --macros Print the netatalk m4 directory. --prefix=PREFIX If specified, use PREFIX instead of the installation prefix that netatalk was built with when computing the output for the --cflags and --libs options. This option is also used for the exec prefix if --exec-prefix was not specified. This option must be specified before any --libs or --cflags options. --exec_prefix=PREFIX If specified, use PREFIX instead of the installation exec prefix that netatalk was built with when computing the output for the --cflags and --libs options. This option must be specified before any --libs or --cflags options. COPYRIGHT
