I tried to compile Python on my Ubuntu 14.04 64 bit by following the
instructions[1], here are some problems i encountered and how i resolved
some of them, hope it helps.
Here was the error message when i built the project:
Include/pyport.h:886:2: error: "LONG_BIT definition appears wrong for
> platform (bad gcc/glibc config?)."
>
then I ran `emconfigure` with several `-m23` flags:
$ CFLAGS='-m32' LDFLAGS='-m32' CXXFLAGS='-m32' emconfigure ./configure
> --without-threads --without-pymalloc --enable-shared --disable-ipv6
>
a new error message was printed after i built the project again:
./Modules/posixmodule.c:6555:1: error: static declaration of 'posix_close'
> follows non-static declaration
> posix_close(PyObject *self, PyObject *args)
> ^
> /home/pzhang/work/opensource/emsdk_portable/emscripten/master/system/include/libc/unistd.h:38:5:

> int posix_close(int, int);
> ^
> ./Modules/posixmodule.c:8933:25: warning: incompatible pointer types

then i removed the declaration of `posix_close` function from
`$EMSCRIPTEN/system/include/libc/unistd.h`, re-compiled the project, the
error message was gone, and everything else went well by following the
instructions[1].
and now i can run the python like this:
node a.out.js -S -c "print 'hello world!'"
>
but the output was like:
Calling stub instead of sigaction()
> Calling stub instead of sigaction()
> Calling stub instead of __libc_current_sigrtmin
> Calling stub instead of __libc_current_sigrtmax
hello world!
>
Calling stub instead of sigaction()

and i tried to run the compiled Python interactively by:
node a.out.js -S
>
the command was terminated with these outputs:
Calling stub instead of sigaction()
> Calling stub instead of sigaction()

How can i run the compiled Python interactively? thanks.
