libtorrent-rasterbar: build fails when ccache is enabled

Description

When the use of ccache is enabled in MacPorts (configureccache yes is set in macports.conf, the ccache port is installed, etc.), MacPorts will set CC to a value containing a space, such as ccache /usr/bin/clang.

A patch was recently added to fix another problem:

  • bindings/python/Makefile.am

    old new  
    3636if ENABLE_PYTHON_BINDING
    3737
    3838all-local:
    39         $(PYTHON) $(srcdir)/setup.py build
     39        CC=$(CC) $(PYTHON) $(srcdir)/setup.py build
    4040
    4141install-exec-local:
    4242        $(PYTHON) $(srcdir)/setup.py install @PYTHON_INSTALL_PARAMS@

These two facts result in a build error when ccache is enabled:

Making all in python
make[2]: Entering directory `/opt/local/var/macports/build/_Users_rschmidt_macports_macports-ports-ryandesign-fork_net_libtorrent-rasterbar/libtorrent-rasterbar/work/arvidn-libtorrent-bc66605/bindings/python'
CC=ccache /usr/bin/clang /opt/local/bin/python3.7 ./setup.py build
clang: error: no such file or directory: 'build'

If I fix the patch to quote CC like this:

  • bindings/python/Makefile.am

    old new  
    3636if ENABLE_PYTHON_BINDING
    3737
    3838all-local:
    39         $(PYTHON) $(srcdir)/setup.py build
     39        CC="$(CC)" $(PYTHON) $(srcdir)/setup.py build
    4040
    4141install-exec-local:
    4242        $(PYTHON) $(srcdir)/setup.py install @PYTHON_INSTALL_PARAMS@

then the build fails with a different strange error:

error: command '/usr/bin/clang++' failed with exit status 1

In other words, compiling succeeds, but linking fails because it's inexplicably trying to invoke /usr/bin/clang++ /usr/bin/clang. I haven't yet been able to figure out why this is so.
