Statically linked plugins (Re: Help Digest, Vol 51, Issue 1)

[Grant Hazelton]

Hi Holger,

Thanks for your quick reply (quicker than my thanks, sorry).

Your reply confirmed my suspicion. I found a few pages which said much the same: difficult, poor idea, insane, etc.

I'm looking into the use of musl.

Best regards.
--Grant.

    Hi all,
    
    I?ve just joined the list.
    
    I have a question about static linking. While I?m working my way through the archive to see if it has already been answered, I?ll ask here in case someone can help.
    
    After configure && make I find that plugins (for example check_apt) are dynamically linked, needing libpthread.so.0 and libc.so.6, etc., according to objdump.
    
    I tried configure LDFLAGS=?-static? && make, and I can see -static added to the libtool command line, but I still get a dynamically linked exe needing the same shared libraries.
    
    What am I doing wrong? (Or misunderstanding?)
    
    Thanks in advance.
    --Grant.

    You can't easily compile a fully static binary on today's Linux/glibc
    systems:
