[Discuss] Compiling a binary

[Hans Oeste]

OK, I'm stumped.
 
I've messed with the Makefile that ./configure produces and it's not working
  Is there a parameter that I can pass to ./configure to make it produce a
static fully linked binary?
 
I have tried sudo ./configure LDFLAGS=-r
And get an error that the C compiler cannot create executeables
 
Huh?

You may want to link some dynamic libraries statically, but keep the
standard system libraries (like libc) dyncamically.
 
You can use ld -r to statically link a bunch of object files and
dynamic .so files to product anoter linkable static .o file.  Here's
an example that statically links in -lm, but still uses a dynamic libc:
 
    $ cat sin.c
    #include <math.h>
    #include <stdio.h>
    int main() { printf("sin(1)=%f\n", sin(1)); }
 
Statically combine sin.o and -lm into sin_lm.o
 
    $ cc -c sin.c
    $ ld -r -o sin+lm.o sin.o -lm
 
Produce final execuatble liked with dynamic libc
 
    $ cc -o sin+lm sin+lm.o
    $ ldd sin+lm
            libc.so.6 => /lib/tls/libc.so.6 (0x4001f000)
            /lib/ld-linux.so.2 (0x40000000)
