Note: Some of the fixes are for newlib in general but not NaCl-specific. * include/ruby/intern.h (rb_fd_select): declare struct timeval, or the struct gets local to the function in C99. * file.c (#include): add nacl/stat.h for PNaCl. (utimes): added a declaration for PNaCl. (stat_atimespec): stat::st_atimensec is long long but timespec::tv_nsec is long in PNaCl. (stat_mtimespec, stat_ctimespec): ditto. (rb_group_member): disable getgroups unless HAVE_GETGROUPS. (eaccess): unify the fallback to generic defined(USE_GETEUID). * io.c: include sys/time.h for struct timeval. (rb_close_before_exec): nothing we can do if F_GETFD is not available. (ioctl): pnacl newlib actually doesn't have ioctl. * process.c (maxgroups): it is used iff defined(_SC_NGROUPS_MAX) || defined(NGROUPS_MAX) but not defined(HAVE_GETGROUPS) || defined(HAVE_SETGROUPS). (obj2gid): fail unless the object is a Fixnum if getgrnam is not available. (disable_child_handler_fork_child): sigaction is not available in PNaCl newlib. * configure.in (warnflags, strict_warnflags): avoid -ansi for strlcpy. (rb_cv_gcc_atomic_builtins): also check __atomic_or_etch because it is used in ruby_atomic.h. (rb_cv_gcc_sync_builtins): ditto. (HAVE_GETGRNAM): added. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47882 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

= Native Client port of Ruby
|
|
|
|
= How to build
|
|
== Prerequisites
|
|
You need to install the following things before building NaCl port of Ruby.
|
|
* Ruby 1.9.3 or later
|
|
* Python 2.6 or later
|
|
* NativeClient SDK pepper 37 or later
|
|
* GNU make
|
|
|
|
== Steps
|
|
(1) Extract all files from the tarball:
|
|
$ tar xzf ruby-X.Y.Z.tar.gz
|
|
(2) Set NACL_SDK_ROOT environment variable to the path to the Native Client SDK you installed:
|
|
$ export NACL_SDK_ROOT=/home/yugui/src/nacl_sdk/pepper_37
|
|
(3) Configure
|
|
$ ./configure --prefix=/tmp/nacl-ruby --host=x86_64-nacl --with-baseruby=/path/to/ruby-1.9.3-or-later
|
|
(4) Make
|
|
$ make
|
|
$ make package
|
|
|
|
Now you have ruby.nexe. You can run it by sel_ldr in NaCl SDK.
|
|
|
|
"make package" installs "pepper-ruby.nexe", an example Pepper application that
|
|
embeds Ruby", and libraries to $prefix. You can run it by the following steps:
|
|
(5) Publish the $prefix directory on a web server
|
|
(6) Visit the example.html on the web server by a browser that implements Pepper 18 or later.
|
|
-- e.g., Chrome 18 implements Pepper 18, Chrome 19 implements Pepper 19, ...
|
|
|
|
=== Example Configurations
|
|
* x86_32 Native Client
|
|
$ ./configure --prefix=/tmp/nacl-ruby \
|
|
--host=i686-nacl \
|
|
--with-baseruby=/path/to/ruby-1.9.3-or-later
|
|
* arm Native Client
|
|
$ ./configure --prefix=/tmp/nacl-ruby \
|
|
--host=arm-nacl \
|
|
--with-newlib \
|
|
--with-baseruby=/path/to/ruby-1.9.3-or-later
|
|
* Portable Native Client
|
|
$ ./configure --prefix=/tmp/nacl-ruby \
|
|
--host=le32-nacl \
|
|
--with-newlib \
|
|
--with-static-linked-ext \
|
|
--with-baseruby=/path/to/ruby-1.9.3-or-later
