I am having issues with glew and linker errors. I have:
put glew32.dll and glew32d.dll in system, System32 and SysWOW64
put glew.h in GL folder
put glew32.lib, glew32d.lib, glew32s.lib in Lib folder
put glew32.lib, glew32d.lib, glew32s.lib, glut32.lib, opengl32.lib in Additional Dependencies
put GLEW_STATIC in preprocessor defintions
However, I am still getting the following errors:
1>project2.obj : error LNK2001: unresolved external symbol ___glewGetProgramInfoLog
1>project2.obj : error LNK2001: unresolved external symbol ___glewGetShaderInfoLog

Is there something obvious I am missing? Is there something else I can try? Thanks.
If you're using the static library glew32s.lib you need to define the preprocessor flag GLEW_STATIC in order for you to resolve the symbols.
You can do this either in-source with
#define GLEW_STATIC
or add it to your pre-processor directives for the project
Project Properties > C/C++ > Preprocessor > Preprocessor Definitions
If you still have unresolved external symbols afterwards you may also need to
add opengl32.lib as an additional dependency for the linker.
If after that you are still having unresolved symbols regarding glew, make sure you actually have it's .lib added to a library directory that your linker searches in. You can add that in
Project Properties > Linker > General > Additional Library Directories

I want to use the R package 'grpreg'. However, I do not want to run it in R. Instead, I want to run the package under python. I have searched that I need to install the package rpy2, which allows me to run an R package under python. After installing rpy2, I enter
> `from rpy2.robjects.packages import importr`
> `base=importr('grpreg')`
Unfortunately, I obtain the error messages:
R[write to console]: Error: package or namespace load failed for 'grpreg' in inDL(x, as.logical(local), as.logical(now), ...):

I would like to know how to fix the problem.
So I try to load by library(genefilter)
But I keep getting the error:
Error: package or namespace load failed for ‘genefilter’ in inDL(x, as.logical(local), as.logical(now), ...): unable to load shared object 'C:/Users/Jerry Yu/Documents/R/win-library/4.0/Rcpp/libs/x64/Rcpp.dll': LoadLibrary failure: The specified procedure could not be found.
I have already tried removing and reinstalling genefilter, but nothing has worked.
I've recently installed the ArcGIS Runtime SDK on my Windows 10 machine running Qt 5.9.1. When attempting to build a simple QWidget application using one of the ArcGIS templates, I get the following errors:

This problem seems to be quite common-place however most of the Google results come up with answers for Linux systems.
I have done the following:
Downloaded and installed OpenSSL (from GnuWin32 OpenSSL)
Copied across the libeay32.dll and libssl32.dll to the build folder
Added the include path into the Qt pro file
Verified that network is in the QT += config section of the pro file
Yet none of the above has made any difference. I'm running MSVC 2015 32-bit kit.
you have to add static libraries to your project.
Find out libeay32.lib and libssl32.lib and add them to your project.
Refer
http://doc.qt.io/qtcreator/creator-project-qmake-libraries.html
I think you need such two dll files:libeay32.dll and ssleay32.dll.I use the same version qt as you do,so you can download them from here or directly get the zip from here (which works for me).
Different version openssl lib used by Qt,so you should test it in you code using static function below if you are not sure about it:
QSslSocket::sslLibraryBuildVersionString();
If somebody else comes across this question, notice that since version 1.1.0 OpenSSL have changed their library names from:
libeay32.dll -> libcrypto.dll
ssleay32.dll -> libssl.dll
So you will need to include those two files with your project in order for QSsl functions to work.
I am trying to get extension R to work with mediawiki but have run into a roadblock with the following error:
REngine.php: sh: /usr/bin/R: No such file or directory
Does anyone know how to correct this issue? If I look at mediawiki/Special:Version, I can see R listed under extensions as version 0.14, but if I try to use <R>1:10</R> it throws that error.
After the comment to add a symlink below I was able to get a little further. I added the following symlink to my brew installation of R:
ln -s /usr/local/Cellar/r/3.1.2_1/R.framework/Versions/3.1/Resources/bin/R /usr/bin/R
and this was the output:
REngine.php: Error in dyn.load(file, DLLpath = DLLpath, ...) :

I am trying to write DLNA project in Qt WinCE. Is there any UPnP library for it?
I am now trying CyberLink C library. But, it only has wrapper for Objective-C.
I got some configuration errors while trying to translate Objective-C wrapper to Qt WinCE wrapper.

Is there any UPnP library for it?
You can try GUpnp
http://gupnp.org/downloads/gupnp-dlna-0.3.0
or try Developer Tools for UPnP to generate skeleton code
