Hi Reinhard,
Building AspectC++ using the Debian clang-4.0 package should work now. Please
use the current AspectC++ trunk version. Sorry for the inconveniences!
The problem was that the linker arguments that point to the system libraries
("-ldl", ...) were missing. These arguments were missing because starting with
version 4.0 the behavior of "llvm-config --system-libs" changed (see [1]) to
only return the system libs if static linking ("--link-static") is selected.
When using the binaries from the Clang download page ([2]) "--link-static"
seems to default to "true" whereas "--link-static" defaults to "false" when
using the Debian clang-4.0 package. I am not sure whether this is the desired
behavior, but changing the AspectC++ makefile to use the command
"llvm-config --system-libs --link-static" forces llvm-config to output the
system libs in hopefully all cases.
Please let me know if it still does not work.
Thank you very much and best regards,
Simon
