I'm confused. Is there no way to link your library code on each platform? That way it will always run wherever it is ported to. It is not clear to me if this is what you are asking.

You seem to want to be able to link your code where ever it resides. You have two choices: link statically on the home machine, or compile to object code - ex: libfoo.a, on the home machine, then link a new PIC code library on each platform. Assuming your code links correctly against various installation of c++.

Static linking kind of defeats the purpose of a library. But it will work.

You cannot depend on version libstsdc++5 or 6 or whatever being available when you port your code. Lugging dynamic code from box to box is not always feasible. As you found out.

NAME
apr-1-config - Return metainformation about apr library SYNOPSIS
apr-1-config [OPTION] DESCRIPTION
The apr-1-config program is used to retrieve information about the apr library in the system. It is typically used to compile and link against the library. When linking with libtool, an application should do something like: APR_LIBS="`apr-1-config --link-libtool --libs`" or when linking directly: APR_LIBS="`apr-1-config --link-ld --libs`" An application should use the results of --cflags, --cppflags, --includes, and --ldflags in their build process. OPTIONS
Known values for OPTION are: --prefix[=DIR] change prefix to DIR --bindir print location where binaries are installed --includedir print location where headers are installed --cc print C compiler name --cpp print C preprocessor name and any required options --cflags print C compiler flags --cppflags print C preprocessor flags --includes print include information --ldflags print linker flags --libs print additional libraries to link against --srcdir print APR source directory --installbuilddir print APR build helper directory --link-ld print link switch(es) for linking to APR --link-libtool print the libtool inputs for linking to APR --shlib-path-var print the name of the shared library path env var --apr-la-file print the path to the .la file, if available --apr-so-ext print the extensions of shared objects on this platform --apr-lib-target print the libtool target information --apr-libtool print the path to APR's libtool --version print the APR's version as a dotted triple --help print the help AUTHOR
