Hi everyone,
I am a beginner on Cap'n Proto and I would like to ask a build question. I
am using Clang 3.5.0 to build Cap'n Proto but failed. What I did for build
was
./configure CXX=clang++ CXXFLAGS='-std=gnu++1y -g'
make
and the build error is as follows:
luckyboy@cse-322osu10:capnproto-c++-0.5.3.1$ make
depbase=`echo src/capnp/compiler/module-loader.o | sed
's|[^/]*$|.deps/&|;s|\.o$||'`;\
clang++ -stdlib=libc++ -DHAVE_CONFIG_H -I. -I./src -I./src

It seems someone had asked similar questions 3 years ago but no official
solution. What I am eager to know is how should I handle this? If I want to
keep using Clang 3.5, is this unavoidable?
Thanks very much for any hints and help!
