I was using sibilingAtColumn to get data from qtableview.
The code was compiled successfully on MacOS, however it raised error when compiling on linux.
The Error was error: ‘class QModelIndex’ has no member named ‘siblingAtColumn’.

This is the demo on Tencent's audio and video real-time processing. I downloaded it from the website and compiled it with QT Creator5.14.2 MinGW 32 bit. The following error occurred:
E:\Qt\qtcode\TXLiteAVSDK_TRTC_Win_latest\TRTC-API-Example-Qt\src\Util\win\zlib\x86\zlibstatic.lib(zlibstatic.dir\Release\crc32.obj):-1: error: undefined reference to `#__security_check_cookie#4'
E:\Qt\qtcode\TXLiteAVSDK_TRTC_Win_latest\TRTC-API-Example-Qt\src\Util\win\zlib\x86\zlibstatic.lib(zlibstatic.dir\Release\adler32.obj):-1: error: undefined reference to `_alldiv'
:-1: error: collect2.exe: error: ld returned 1 exit status
I searched the Demo question on the Internet, but basically used vs code instead of QT Creator+MinGW
In my own Frama-C plugin, I would like to use ppx_compare for generation of compare functions. After adding the following line to my plugin's Makefile:
PLUGIN_REQUIRES = ppx_compare
the plugin is successfully compiled and installed, but running frama-c fails with the following error message:
[kernel] User Error: cannot load plug-in 'base': cannot load module
Details: The module `Base' is already loaded (either by the main program or a previously-dynlinked library)
[kernel] User Error: cannot load plug-in 'ppx_compare.runtime-lib': cannot load module
Details: interface mismatch on Base
[kernel] User Error: Deferred error message was emitted during execution. See above messages for more information.
[kernel] Frama-C aborted: invalid user input.
This seems to be a conflict of Frama-C's Base module and Jane Street's Base library. Is there any workaround for this problem?
I wanted encrypt my PHP source code using the blenc_encrypt function, but it is giving me error like this:
Fatal error: Uncaught Error: Call to undefined function blenc_encrypt()
I have tried to figure out in php_ini setting to uncomment extension like blenc_encrypt but there is no such setting available. What do I do to have blenc_encrypt available?
I am using php7.3
I am trying to install ROOT (6.10.08) on a Linux Subsystem on Windows (Ubuntu 16.04). More details are described here. When I try to build root (cmake --build .), 69% through the build, I run into the following problem:

I'm a beginner and am following the steps as closely as I can. I was wondering if anyone could offer advice as to the errors I am running into, and potential fixes.
Thanks!
I am trying to compile a cmake project for symbian using QtSDK (Qt 4.7).
When I build it within the Qt Creator, I get these errors:
C:/QtSDK/Symbian/SDKs/Symbian3Qt473/include/QtCore/qatomic_symbian.h:46: error: e32std.h:
No such file or directory
C:/QtSDK/Symbian/SDKs/Symbian3Qt473/include/QtCore/qatomic_symbian.h: In member

C:/QtSDK/Symbian/SDKs/Symbian3Qt473/include/QtCore/qatomic_symbian.h:141: error: expected primary-expression before ')' token
I have checked that e32std.h exists at C:\QtSDK\Symbian\SDKs\Symbian3Qt473\epoc32\include
But still these errors occur.
It seems to me that cmake is not able to find the correct architecture for compilation.
I am using cmake for windows.
What could be the problem ?
