<-- and it's missing a dependency on some other library.
Comment 1 Lon Hohberger 2005-08-31 18:18:57 EDT
You're right, the lib should be 0755

The dependency is on libmagma.  Basically, we separated libmagma and libmagmamsg
so that we could make sure libmagma was LGPL-licensed.  Libmagmamsg requires
libmagma at link time when building an application against it.

The socket handling code in libmagmamsg dates back GPL code from Mission
Critical Linux ca. 2000, and is GPL-licensed, which is why libmagmamsg is
separate in the first place...

+	${LD} -shared -soname libmagmamsg.so.$(RELEASE_MAJOR) -o $@ $^ -Bdynamic -lc
-L. -lmagma -lpthread -ldl

you should never ever ever be linking anything using ld directly.  use

   gcc -shared ...

and the explicit -lc is not necessary either.
Comment 4 Lon Hohberger 2005-09-01 11:10:50 EDT
I know the explicit lc isn't necessary, I was just using what was in the makefile ;)

The whole makefile would need to be rewritten to make it not use LD directly..
To be honest, I don't know where that came from, I was sure I was using gcc.

Remove already-committed mode change
Comment 7 Joe Orton 2005-09-01 11:22:20 EDT
-Bdynamic is also redundant on Linux, otherwise that looks good.
Comment 8 Chris Feist 2005-09-01 12:18:45 EDT
The fixes have been commited upstream and should show up in the next fedora core
build of magma.
