Hi, [sleepycat support removed, libtool added]
A secondary issue is that changing this to "-Wl,-flat_namespace -Wl,-undefined -Wl,suppress" does not work, and the string passed to g++ must be "-Wl,-flat_namespace -Wl,-undefined suppress"
While I have seen this issue before, I have never seen a failure associated with it. Is sleepycat seeing an actual failure?
Here is what I get with sh -x and libtool's tagdemo with -no-undefined removed from the makefile:
++ cmd=g++ -dynamiclib -single_module ${wl}-flat_namespace ${wl}-undefined ${wl}suppress -o .libs/libbaz.0.0.0.dylib .libs/baz.o .libs/libbaz.lax/libfoo.a/foo.o -install_name /Users/peter/libtool-1.5.10/tests/_inst/lib/libbaz.0.dylib -Wl,-compatibility_version -Wl,1 -Wl,-current_version -Wl,1.0
+ echo 'g++ -dynamiclib -single_module ${wl}-flat_namespace ${wl}-undefined ${wl}suppress -o .libs/libbaz.0.0.0.dylib .libs/baz.o .libs/libbaz.lax/libfoo.a/foo.o -install_name /Users/peter/libtool-1.5.10/tests/_inst/lib/libbaz.0.dylib -Wl,-compatibility_version -Wl,1 -Wl,-current_version -Wl,1.0'
g++ -dynamiclib -single_module ${wl}-flat_namespace ${wl}-undefined ${wl}suppress -o .libs/libbaz.0.0.0.dylib .libs/baz.o .libs/libbaz.lax/libfoo.a/foo.o -install_name /Users/peter/libtool-1.5.10/tests/_inst/lib/libbaz.0.dylib -Wl,-compatibility_version -Wl,1 -Wl,-current_version -Wl,1.0
+ eval 'g++ -dynamiclib -single_module ${wl}-flat_namespace ${wl}-undefined ${wl}suppress -o .libs/libbaz.0.0.0.dylib .libs/baz.o .libs/libbaz.lax/libfoo.a/foo.o -install_name /Users/peter/libtool-1.5.10/tests/_inst/lib/libbaz.0.dylib -Wl,-compatibility_version -Wl,1 -Wl,-current_version -Wl,1.0'
++ g++ -dynamiclib -single_module -Wl,-flat_namespace -Wl,-undefined -Wl,suppress -o .libs/libbaz.0.0.0.dylib .libs/baz.o .libs/libbaz.lax/libfoo.a/foo.o -install_name /Users/peter/libtool-1.5.10/tests/_inst/lib/libbaz.0.dylib -Wl,-compatibility_version -Wl,1 -Wl,-current_version -Wl,1.0
As you can see the ${wl} is printed with the $echo, but when g++ is actually called, it is properly eval'ed.
Gary, we need some tests without -no-undefined on platforms which support generating shared libraries with undefined symbols.
