I went ahead and did as:
and added symlinks from /usr/lib and /usr/include/c++. It compiled OK;
however, the link failed with:
ls -ld /usr/lib/libc++*
lrwxrwxrwx 1 root root 69 Feb 5 07:09 /usr/lib/libc++.so ->
ls -ld /usr/include/c++/v1
lrwxrwxrwx 1 root root 59 Feb 5 07:14 /usr/include/c++/v1 ->
-stdlib=libc++ move.cpp -o move.exe
undefined reference to `__cxa_free_exception'
undefined reference to `__cxa_begin_catch'
undefined reference to `__cxa_guard_release'
I didn't link to path-to-libcxx/lib/libc++.1.dylib
because there was no such file. Instead, I figured
that was a MacOS convention for shared libs; so,
I substituted the only likely file in the target
Now I did *not* do the download and install of:
because the webpage:
To build on Mac OS X 10.6, you need a helper library and header found
here. cp cxxabi.h to /usr/include, and cp libc++abi.dylib to
and I'm on ubuntu, not Mac OS X.
Am I missing something?
