kandi X-RAY | double-conversion Summary
This project (double-conversion) provides binary-decimal and decimal-binary routines for IEEE doubles. The library consists of efficient conversion routines that have been extracted from the V8 JavaScript engine. The code has been refactored and improved so that it can be used more easily in other projects. There is extensive documentation in double-conversion/string-to-double.h and double-conversion/double-to-string.h. Other examples can be found in test/cctest/test-conversions.cc.

QUESTION
I'm trying to cross-compile Qt 6.2.1. Target - Windows, my machine OS - Linux (Mint 20.2) (both 64bit). Unfortunately I can't compile it on Windows, so I have to do this cross-compilation.
My configure cmd:
...ANSWER
Answered 2021-Dec-03 at 12:14For those coming here from google with same problem.
In Qt6 you need to specify Cmake toolchain for cross-compilation (I get something similar to toolchain shared here), as 'alone' device-option CROSS_COMPILE (as in cmd from my question) is depreciated/outdated (or smth like that).
In my case I needed to use CMake toolchain and device-option CROSS-COMPILE as well, because in other way qmake was not able to find proper cross-platform compiler (in my case x86_64-w64-mingw32-g++-posix). To use compiler with "posix" at the end I needed to modify qtbase/mkspecs/win32-g++/qmake.conf. This is how it looks like after changes:

So I have a problem, the Qt installer just fails when I try to install Qt 6.2.1, and I figured I will have to compile the source myself to get it to work. The configure.bat
command line I have is:
ANSWER
Answered 2021-Nov-29 at 13:39The issue is the platform
parameter. Please replace win32-msvc2019
with win32-msvc
.
The issue compiler cannot find the file because it is in qtbase\mkspecs\win32-msvc
folder, but in your case it is looking in qtbase\mkspecs\win32-msvc2019
.
I have checked help of the configure script, there is no information about possible values. As well as in the Qt documentation. It seems the only possible way to check the correct values is to list mkspecs folder

ANSWER
Answered 2021-Mar-19 at 05:03The official answer: "On macOS, x86_64 is the only supported architecture and running Drake under Rosetta 2 emulation on arm64 is not supported." -- https://drake.mit.edu/developers.html#supported-configurations as of 2021-03-18.
You can subscribe to https://github.com/RobotLocomotion/drake/issues/14555 for any updates regarding M1 support.
However, if you want to try to hack through it locally, you could try commenting out homebrew dependencies that do not succeed (e.g., IBEX in this case).
With IBEX disabled, you'll also have to bazel build --define=NO_DREAL=ON
to disable dReal for the moment. Likely, other dependencies will also fail, but we have not tested on M1 yet so we don't know how close it is to working.
I've filed https://github.com/dreal/homebrew-dreal/issues/10 in case we can fix the IBEX problem easily.
The other option would be to spin up an Ubuntu VM (based on either 18.04 or 20.04).

QUESTION
I'm trying to build a Debian package which uses the Qt5 library. I have Qt installed in /opt and the libraries can be found at /opt/Qt/5.15.0/gcc_64/lib
.
The binaries I'm trying to put in a Debian package are written in C++, and I'm using CMake to as buildsystem.
My debian/rules file contain the following:
...ANSWER
Answered 2020-Aug-04 at 08:04I figured out how to fix it. The main problem was in my CMake file.
In my CMake I just did find_package(Qt5 COMPONENTS Core Quick REQUIRED)
. But CMake install does not know where the libraries can be found to link with.
So I had to set CMAKE_INSTALL_RPATH
variable. In my case I had to set it to /opt/Qt/5.15.0/gcc_64/lib/
. (This can be done via command line using -D
)
To automate this process I based the variable around the Qt5_DIR
variable which is needed for CMake to find all the Qt modules.

Answered 2020-Jul-09 at 09:03Question 1: Inconsistent behaviour is indeed due to partitioning.
Question 2: Workaround found: Converting first to rdd and then immediately back to data frame solved the issue (i.e. adding .rdd.toDF()). I am unclear about the reason, probably something going on in the background that I don't understand.
