* cmake: change how test files are build when cross compilingPhilip Balister2021-12-031-0/+3
| | | | | | | | | | | | | | | | | | | | * When cross compiling gnuradio, change how the test files are built. Normally, the gnuradio QA code expects to run in the build tree. For the cross compilng case, we cannot run the QA code during the build process. The changes here allow the creation of an additional package that can be installed on a target that will run the QA code against the installed libraries. Major changes are not using full paths to test files (since they include paths that only exist on the build machine) and not setting environment variables in the shell files to force the QA code to use code in the build tree. This patch disables the C++ only tests, these need some work and then they can be added back for the cross compile case. Signed-off-by: Philip Balister <philip@balister.org>

* fft: window: Allow normalizing windowsMartin Braun2020-08-142-2/+40
| | | | | | | | In some applications, it is useful to generate windows that have unit power. The boxcar window (rectangle) is always of unit power, but the other windows are not, leading to apple-to-oranges comparisons, e.g., when switching between window types in a live spectrum estimation application.
* fft: window: Provide default value for beta param on window::buildMartin Braun2020-08-141-1/+1
| | | | | | | | | | | | The API call fft::window::build() takes a third parameter, beta, that only applies for the Kaiser window. For other windows, it is necessary to provide a dummy value to call this function. The declared-deprecated version firdes::window() on the other hand does not require specifying beta when not needed. Instead, we provide a default value of 6.76 which will still generate a valid (and generally useful) Kaiser window, but means we don't have to specify beta for other windows.
* fft: window: Add WIN_NONEMartin Braun2020-08-141-1/+1
| | | | | fft::window is slated to replace firdes::window, we add the missing WIN_NONE for consistency between the two.
* python: Remove unnecessary 'from __future__ import'Oleksandr Kravchuk2020-08-034-6/+0
| | | | | | | | | | | | | | | | All of the removed `from __future__ import` were needed in older versions of Python (mostly 2.5.x and below) but later became mandatory in most versions of Python 3 hence are not necessary anymore. More specifically, according to __future__.py[1]: - unicode_literals is part of Python since versions 2.6.0 and 3.0.0; - print_function is part of Python since versions 2.6.0 and 3.0.0; - absolute_import is part of Python since versions 2.5.0 and 3.0.0; - division is part of Python since versions 2.2.0 and 3.0.0; Get rid of those unnecessary imports to slightly clean up the codebase.

|/ | | | | | That is especially hurt as the GRC template puts defaults to `ref_scale=2` (int literal!) and if someone uses `1`, they'll get zero internally in logpwrfft, and that leads to errors.
* Fix the VOLKized fft_vcc_fftw and QA codeDoug Geiger2015-09-211-4/+60
| | | | | | | The QA code did not cover all the cases being VOLKized, and thus failed to notice the incorrect pointer math. This QA code (correctly!) fails on the previous commit, and (correctly!) passes with this fix to fft_vcc_fftw.cc. Thanks to awalls-cx18 for noticing this, and providing the correct array indexing call to VOLK. Fixes issue #844

| | | | | | | | | | | | cross compiling. With this (and the prior) patch, you can mount the compile directory on the target and run the QA code (as long as the paths are the same). The qtgui tests fail if there is no X server. Volk seems to fail for hard float builds. We'll need to look at adding thes changes to gr_modtool. Signed-off-by: Philip Balister <philip@balister.org>

| | | | | | | | | | | | Remove window.py. All windows built using C++ functions. Exported into Python in same module (from gnuradio.fft import window). Removed all window building work in firdes, too. firdes.window now makes a direct call to fft.window.build with same parameters. Added documentation for window functions, including references to where to find coefficients and equations for (most of) the windows. All changes should not affect existing code. f
