misc/uClib++ README |
||||
^^^^^^^^^^^^^^^^^^^ |
||||
|
||||
This directory contains a version of the uClibc++ C++ library. This code |
||||
originates from http://cxx.uclibc.org/ and has been adapted for NuttX by the |
||||
RGMP team (http://rgmp.sourceforge.net/wiki/index.php/Main_Page). |
||||
|
||||
uClibc++ resides in the misc/ directory rather than in the main NuttX source |
||||
tree due to licensing issues: NuttX is licensed under the permissiv |
||||
modified BSD License; uClibc, on the other hand, islicensed under the |
||||
stricter GNU LGPL Version 3 license. |
||||
|
||||
Installation of uClibc++ |
||||
^^^^^^^^^^^^^^^^^^^^^^^^ |
||||
|
||||
If you wish to use uClibc++ with NuttX, you will be required to comply with |
||||
the licensing requires of the GNU LGPL Version 3 license. A simple |
||||
installation script is provided at misc/uClibc++/install.sh that can be used |
||||
to install the uClibc++ components into the NuttX source tree. |
||||
|
||||
The install script takes only a single arguement: The path to the nuttx |
||||
directory. If your directory structure is the same as the SVN structure |
||||
(with misc/ and nuttx/ at the same level), then uClibc++ can be installed |
||||
using this command executed from the misc/uClibc++ directory: |
||||
|
||||
./install.sh ../../nuttx |
||||
|
||||
If you run the install.sh like this, then it will (1) make sure you |
||||
understand that you have tainted the NuttX BSD license with LGPLv3, and (2) |
||||
copy the uClibc++ sources files into nuttx/libxx/uClibc++, include/, and |
||||
include/cxx. |
||||
|
||||
Building NuttX with uClibc++ |
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
||||
|
||||
After installing uClibc++ in this way, no additional steps should be |
||||
required to build NuttX with the uClibc++ library incorporated: |
||||
|
||||
$ cd ../../nuttx |
||||
$ . ./setenv.sh |
||||
$ make |
||||
|
||||
Here is how it works: |
||||
|
||||
There is a new file called Make.defs in misc/uClibc/libxx/uClibc++. After |
||||
installation, it will reside at nuttx/libxx/uClibc++. The |
||||
nuttx/libxx/Makefile will (conditionally) include this Make.defs file: |
||||
|
||||
-include uClibc++/Make.defs |
||||
|
||||
This Make.defs file, if present, will add the uClibc++ source files to the |
||||
build, add the uClibc++ subdirectory to the dependency list, and add the |
||||
uClibc++ subdirectory to the VPATH. That should, in principle, be all it |
||||
takes. |
||||
|
||||
Dependencies |
||||
^^^^^^^^^^^^ |
||||
|
||||
In order to build libxx (and hence libxx/uClibc++), CONFIG_HAVE_CXX must be |
||||
defined in your NuttX configuration file. |
||||
|
||||
The C++ runtime support is provided by GCC libgcc_eh.a and libsupc++.a |
||||
libraries. |
||||
|
||||
RGMP |
||||
^^^^ |
||||
|
||||
The target platform is RGMP X86, it is also updated for TLS support which is |
||||
needed by these two libraries. So application can also use TLS on RGMP NuttX |
||||
port. |
||||
|
||||
Command to compile and install RGMP: |
||||
|
||||
$ make |
||||
$ make install |
||||
$ /usr/rgmp/setup |
||||
$ exit |
||||
|
||||
Command to compile and run NUTTX: |
||||
|
||||
$ cd nuttx/tools |
||||
$ ./configure rgmp/x86/cxxtest |
||||
$ cd .. |
||||
$ make |
||||
$ rgmp_run |
