Shared Objects
Hi. Does anyone know by how much a text size of an executable(on ibm) would grow if you link one shared object(library)? Is it a constant number or it depends on a .so that is linked?

I'm runtime linking (dlopen and dlsym) to a shared object (library) I've created and after a number of function calls into the library the program core dumps (Illegal operation). This only occurs during runtime linking. If I use the same library and dynamically link during compile time everything... (3 Replies)

Where will the pointers point to in each process ?
The objects are supposed to reside in shared memory

ostrip(1) General Commands Manual ostrip(1)
NAME
ostrip - Reduce the size of object files
SYNOPSIS
ostrip [options] file...
OPTIONS
The following options are supported by the ostrip command: Removes the section of a linked image. Removes unreferenced symbols and unused
type information from the symbol tables of a pre-link file. This results in a smaller on-disk executable file. If files modified with this
option are subsequently linked, ostrip -m should be run on the linked image. Joins together two files that were previously split by the -t
option into a symbol table file (image.stb) and a stripped image file (image). Removes unreferenced symbols and unused type information
for the symbol tables of a post-link executable file. This results in a smaller on-disk executable file. The symbol table still contains
all information required for debugging. Decompresses the output of ostrip. This option is provided for cases in which the input file is
compressed in ALPHAMAGICZ format. Removes the symbol table and any strippable subsections of the section. (Performs the same operations as
the strip command.) Splits an image file (image) into a symbol table file (image.stb) and a stripped image file (image). The symbol table
file will contain a checksum of the stripped image. Displays the version of the ostrip command. Produces a reduced symbol table by remov-
ing local information. Also deletes any locally strippable subsections of the section. (Performs the same operations as the ld -x com-
mand.) Compresses the output of ostrip into ALPHAMAGICZ format.
DESCRIPTION
The ostrip command reduces the components of any object file based on the options that are specified. It is designed to work with any
object file, that is, files, image files, and shared object files. It does not work with (archive) files.
RESTRICTIONS
None.
EXAMPLES
The following command strips the local symbol table and converts the object file into ALPHAMAGICZ format: ostrip -x -Z obj.o The following
command produces the symbol table file osize_mm.stb and the stripped image file osize.mm: ostrip -t osize.mm The following command joins
the symbol table file osize_mm.stb to osize.mm: ostrip -j osize.mm
