ddrescue: Builds with wrong C++ stdlib; doesn't use MacPorts CXXFLAGS/LDFLAGS

P.S. I am using libc++ on Lion. Looks like that might be the problem.

[kencu (Ken)]

You should keep using libc++ on Lion, otherwise you will have untold horrors dealt up on you :> .

Ignore those @rpath warnings -- they are just noise for this error. I build clang with the @rpath turned on as it really needs that to work.

The issue here is with ddrescue, that is forcing libstdc++ somehow. I'll take a look and see why that is.

[kencu (Ken)]

ddrescue is not using the CXXFLAGS and most other flags that MacPorts provides, for example see this build on 10.6.8:

creating config.status
creating Makefile
VPATH = .
prefix = /opt/local
exec_prefix = $(prefix)
bindir = $(exec_prefix)/bin
datarootdir = $(prefix)/share
infodir = $(datarootdir)/info
mandir = $(datarootdir)/man
CXX = /opt/local/bin/clang++-mp-9.0
CPPFLAGS = 
CXXFLAGS = -Wall -W -O2
LDFLAGS = 
OK. Now you can run make.

/opt/local/bin/clang++-mp-9.0  -Wall -W -O2 -c -o rational.o rational.cc

it runs with the compiler defaults... and on 10.7.5 clang defaults to libstdc++ if not told otherwise.

To build it for today, please just build it with clang-9.0; I have adjusted the clang-9.0 defaults to make that work. So this works:

sudo port clean ddrescue
sudo port -v install ddrescure configure.compiler=macports-clang-9.0

to fix this properly the port will need to be surgerized to use MacPorts flags and environment variables properly.

[kencu (Ken)]

this PR is meant to fix this issue <​https://github.com/macports/macports-ports/pull/9255>

[RobK88]

Thanks Ken. I was able to build and install ddrescue using clang-9.0 but I had to uninstall ddrescue first.

I tried "sudo port clean ddrescue" as you suggested but that not not enough. The build still failed with broken port. But after I did "sudo port uninstall ddrescue", I was able to build and install ddrescue using "sudo port -v install ddrescue configure.compiler=macports-clang-9.0"

Thanks again!
