QUESTION
I has Mac OS big sur 11.1, Xcode 12.3(12c33), qt 5.14.2 + qt creator 4.11.1 ( installed with online installer). I made simple project qt quick, build for macos working well, but when i try to build it for iOS emulator, I getting this error:
...ANSWER
Answered 2021-Feb-26 at 15:41I found a solution. You need to find all files called as "toolchain.prf" in qt instalation directory and change this code:
QUESTION
First question here.
I have some troubles with the XCode Build System, specifically with preprocessor definitions.
I'm trying to define a macro for the objective-c runtime to avoid enforcing the dispatch functions to be cast to an appropriate function pointer type. The usual way to go would be to use #define OBJC_OLD_DISPATCH_PROTOTYPES
and then include the header on the next line. Once the header gets included, the macro is already defined and the header is configured accordingly.
But that's where it starts to get weird!
The macro is not recognized at all and the header gets included as if the #define
statement was not there so it fails to #define OBJC_OLD_DISPATCH_PROTOTYPES
and it gets (re?)defined as 0.
main.c

I'm trying to get triSYCL to work and for that I need OpenMP. I'm trying to build my project with this CMakeLists file:
...ANSWER
Answered 2020-Jun-17 at 15:38I'm Idiot! I don't even have to run CMake on triSYCL because it's a headers only library. I found that on this website in the top of the documentation section
So I can use this CMakeLists.txt file and it works perfectly:
QUESTION
I'm trying to build WRF 4.2, but have run into some errors due to a macro not being expanded by the preprocessor.
Essentially, WRF is build by csh scripts that configure and then compile the source. Part of that configuration process takes fixed format Fortran (.F files), and transforms them into free format Fortran files(.f90) which are then compiled into object files. The commands being run are generated according to the user's selected platform and compiler configuration, which for me is Darwin architecture, GNU (gfortran/gcc) compilers. I'm trying to compile the "serial" configuration. Here is the part of the output I'm concerned with:

Answered 2020-Jun-05 at 16:23This behavior of clang's cpp when using -traditional-cpp
has been reported back in 2013, with no followup to date. It seems like it's probably a bug, since gcc's preprocessor doesn't do it (example), and it looks like clang prior to version 3.2 didn't do it either. But the the intended semantics of -traditional-cpp
are not precisely defined anywhere that I know of, and the clang maintainers didn't respond to the bug report, so it's hard to know for sure. It's also possible that they just don't care about -traditional-cpp
and consider it obsolete.
It looks like -traditional-cpp
is the default for your installation when running cpp
standalone. I don't know exactly how to turn it off, but -std=c90
might do it. Note that clang -E
also avoids traditional mode and seems to behave correctly.
You can also use gcc's preprocessor instead which doesn't have this "bug". As you found, on your system the gcc
command is actually clang, but you can install the real gcc from Homebrew.
QUESTION
My puzzle is how the compiler can compile those two same name struct.
objc_class definition in "objc/runtime.h" which open to developers
...ANSWER
Answered 2020-Mar-04 at 22:18One is what you see when using the runtime from your code. The other is what the runtime uses internally as an implementation detail.
Note that in both cases the first slot is the isa
(though the objc-runtime-new.h
effectively inherits that slot from objc_object
) and the second slot is the superclass
.
Those are the only two slots accessible from outside the runtime. Internally to the runtime, the struct has more entries for the rest of the metadata associated with the class.

So I have managed to get some simple webassembly application running in the browser, I managed to call webassembly code from Javascript. However when I try to call Javascript from C code I can't get the code to compile

Answered 2019-Dec-17 at 00:33You need to also declare __console_log
as extern "C". That clue is in that fact that function signature is included in the error message. lld is demanding the C++ symbol here (perhaps it would be more clear if it didn't, I'm not sure).

QUESTION
I am on MacOS Mojave 10.14. I can compile wxWidget code and have compiled a few demos, etc. The only feature of wxWidget I cannot compile is a wxRichTextCtrl. Whenever I do the following in my main.cpp file I get error:
...ANSWER
Answered 2019-Nov-05 at 09:57By default, wx-config --libs
returns only the "standard" libraries (which basically were all the existing libraries back when this was implemented) and not all the available libraries to make it possible to add more libraries later without changing anything for the applications that don't need them.
So if you need to use a library not included in this "standard subset", you must specify it explicitly, like this: wx-config --libs std,richtext
.
QUESTION
After updating to iOS 13.x / iPadOS 13.x we see sporadic crashes with our recent Testflight builds. We've not seen reports from users using our pre-13 released version yet, but it seems not many have updated to 13 yet, so we really don't know.
The app is a cordova-app with cordova-ios 5.0.2 using WkWebView. Data protection entitlement is set to full.
I have a hard time making sense of the crash, and it seems to be somewhere deep in the iOS-stack? The crash is sporadic and seems only to happen occasionally when the app has been put into the background.
I'm looking for some guidance/pointers on how to get to the bottom of this.
Crash report from TestFlight:
...ANSWER
Answered 2019-Oct-04 at 13:41It seems that the dyld3 saves the generated clojure files in the app tmp directory and if you use NSFileProtectionComplete the closure files have this property too.
To generate a crahs close the app, lock the phone, send a push that will wake up the app and then the crash is generated.
The solution seems to be simple, just change the permissions for the app tmp direcptry to NSFileProtectionCompleteUntilFirstUserAuthentication and the app will not crash. I really don't know why apple did this.
