[Buildroot] add a new package: PyQtGraph

[Buildroot] add a new package: PyQtGraph

[Guillaume William Bres]

Hi guys,

PyQtGraph is based on the PyQt framework, it is an easy to use 
library to build advanced, science related, plots/user interfaces.

It is easy to build since it is only made of Python scripts.

It depends on Python-Numpy which required a GLIBC toolchain
by the time I created a patch (10/05/2015) but that might
have changed in the mean-time.

I guess i met your requirements for 'selects/depends on',
check this out and enjoy it.

[Buildroot] [PATCH 2/2] Add new package PyQtGraph

[Arnout Vandecappelle]

 Hi Guillaume,

 Thank you for your contribution. I have some comments below, could you adapt
your patch accordingly and resubmit?

 First of all, we require all commits to carry a Signed-off-by tag by which you
certify that you have the right to contribute this commit under the Buildroot
license (GPLv2). See [1].

 Second, the addition in the package/Config.in menu should be done in the same
commit, otherwise the commit is not stand-alone.

 Third, we typically use the following commit summary for new packages:

pyqtgraph: new package


 When you resubmit, please provide a patch changelog that indicates what you
have changed compared to this version.

 No need for all the capitalisation or punctuation, also we have a standard
formulation:

comment "python-pyqtgraph nees a (e)glibc toolchain w/ wchar and C++"

 But actually, you don't have this dependency below, so I'm not sure where you
get it from?

 That said, I think you should not depend on python-pyqt, but select it. And
then you have to propagate the pyqt dependencies. In addition, you have to
propagate the numpy dependencies. Gwenhael has just posted a patch to make that
easier, so it would become:

comment "python-pyqtgraph needs a toolchain w/ C++, threads"
	depends on BR2_PACKAGE_PYTHON_NUMPY_ARCH_DEPENDS
	depends on BR2_USE_MMU
	depends on !BR2_INSTALL_LIBSTDCPP || !BR2_TOOLCHAIN_HAS_THREADS

config BR2_PACKAGE_PYTHON_PYQTGRAPH
	bool "python-pyqtgraph"
	depends on BR2_PACKAGE_PYTHON_NUMPY_ARCH_DEPENDS
	depends on BR2_USE_MMU # pyqt -> qt
	depends on BR2_INSTALL_LIBSTDCPP # pyqt -> qt
	depends on BR2_TOOLCHAIN_HAS_THREADS # pyqt -> qt

(if you cut & paste this, take care that it starts with tab, not spaces).

 That depends on BR2_PACKAGE_QT_GUI_MODULE, so you have to select that as well.

 You should wrap lines at 72 columns (where tab counts as 8 spaces, so 62 real
characters).

 This should specify the place where you can find the MD5, not where you
downloaded it.

 Are numpy and pyexpat runtime dependencies only? If so, you should add comments
to that effect in Config.in.


 I have marked your patches as Changes Requested in our patch tracking system
[2], so we will forget about your patches unless you send a new version.

 Thanks!

 Regards,
 Arnout
