If so, I'd add -brtl to # DLDFLAGS as well as LDFLAGS. I only saw this problem with tcltklib.so. If I understand the documentation correctly, I think you want -brtl for dynamic libraries in general. (The documentation also notes that this feature is only supported in AIX versions 4.2 and later.) The -brtl flag already shows up in a couple of other places (I think from a change you made sometime around last December): .... cc -g -brtl -Wl,-bE:ruby.imp main.o libruby.a -ldl -lcrypt -lm -o ruby .... cc -g -brtl main.o dmyext.o libruby.a -ldl -lcrypt -lm -o miniruby compiling Win32API Conrad Schneiker (This note is unofficial and subject to improvement without notice.)
