[M3devel] a hope for dynamic linking!

[Jay]

I mean for the "regular" Modula-3 "app" stuff, not cm3cg.

It looks like it is already static, good.

1) http://gcc.gnu.org/ml/gcc/2006-10/msg00141.html

2) The current code:

m3-sys/m3cc/gcc/Makefile.in:

configure-gmp: 
...
    echo Configuring in $(HOST_SUBDIR)/gmp; \
...
      $(HOST_CONFIGARGS) --build=${build_alias} --host=none-${host_vendor}-${host_os} \
      --target=none-${host_vendor}-${host_os} $${srcdiroption} --disable-shared \
      || exit 1
@endif gmp


configure-mpfr: 
...
    echo Configuring in $(HOST_SUBDIR)/mpfr; \
...
      $(HOST_CONFIGARGS) --build=${build_alias} --host=none-${host_vendor}-${host_os} \
      --target=none-${host_vendor}-${host_os} $${srcdiroption} --disable-shared --with-gmp-build=$$r/$(HOST_SUBDIR)/gmp \
      || exit 1
@endif mpfr


Let me test it and then I'll remove the Quake code related to this.

Hold on!  I am strongly in favor of static linking for cm3cg/m3cgc1 so that it is a standalone executable.  Should be easy enough with gcc configure.

but yet:

So you can either colocate executables and .sos in the same directory or, like
  /cm3/bin 
  /cm3/lib/m3core.so 

and vary the install root.

We should be using this where available -- Linux, Solaris, Irix.
Too bad not supported elsewhere.
On Windows you can colocate; the .exe's directory is always searched.
