Building an ELF library questions:
I have been trying to rebuild a few of the libraries that I use to
be in elf format. Is the following the correct way to build an elf library?
for every file:
cc -c -fpic file.c
ld -o shared/file.o -x -r file.o
cc -shared -Wl,-x -o libA.so.1 -Wl,-soname,libA.so.1 `lorder file1 file2 ... | tsort`
Does `ld -shared ...` not work correctly any longer? When I used
`ld -shared ...` to build a shared library and `ar` to build an archive
in the same directory, the linker seemed to prefer to link to the archive
instead of the shared library.
Mush ELF libraries have a name of the form libName.so.version or
can try be of the form libName.so.version.reversion?
Linking to an ELF library question:
I seem to remember there being an environment variable that could be
set that held a search path for the linker. Setting this variable was
like adding a -L<path> flag to the link line. Is such a thing still
available? Mainly I would like to avoid adding "-L/usr/X11/lib" to
a bunch of Makefiles.
Thanks.
