I can't compile anything in QtCreator - not even a standard QWidget example application. On compilation I get:/usr/include/qt5/QtCore/qglobal.h:82: error: algorithm: No such file or directory and it sets the cursor toline 82 in global.h at #include <algorithm> - why is this, what is missing on this machine?
UPDATE:
What I did: I created a project using QtCreator on another computer which works & compiles fine. I copied it to this one, tried to start it but get an error:: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: versionGLIBCXX_ 3.4.21' not found (required by- hence I then tried to recompiled it with the provided Makefile but I get a whole buch of errors (pages or errors). So My intention was to fire upQtCreator` and see if i can compile it from within but no dough due to the above error....What's going on and how do I get things back in order?

internal error in mingw32_gt_pch_use_address, at config/i386/host-mingw32.c:190: MapViewOfFileEx: Attempt to access invalid address.
I get this error while compiling a c++ program in sublime-text 3.
How to resolve this error?
In my case, this problem is due to #include<bits/stdc++.h>. Comment this line and get #include <iostream> to solve the problem.
If you have precompiled <stdc++.h> then you have stdc++.h.gch file in this path (path could be different on basis of where you installed MinGW and version) :
C:\MinGW\lib\gcc\mingw32\9.2.0\include\c++\mingw32\bits
So to solve this problem delete stdc++.h.gch file and paste these two commands in your terminal :
Go to the path having your precompiled header in command line
cd C:\MinGW\lib\gcc\mingw32\9.2.0\include\c++\mingw32\bits
Precompile header (mine version is c++17)
g++ -std=c++17 stdc++.h
I have found this solution on a codechef discussion and it works for me.
I got this problem after installing CodeBlocks, maybe it is because of codeblocks MINGW settings. My initial MinGW is from DEV-C++.
So what I did is this.
1.Delete "C:\...\GnuWin" from PATH.
2.Ensure that you have your old path to your compiler. In my case it was "C:\...\DevCPP\Mingw\bin"
For me, this error popped up right after I updated my SublimeText application to the latest version, so just restarting the system worked for me!
I'm not sure what caused this problem today, but I have seen it a few times before.
For me, a full clean and recompile solves it.
I got this same problem after pre-compiling the stdc++.h file, to get rid of this error, I removed the compiled version of this header that is stdc++.gch.
File path of stdc++.h and stdc++.gch is
C:\Users\UserName\Downloads\MinGW\include\c++\9.2.0\x86_64-w64-mingw32\bits
I'm trying to run the example "Scale_Space_Surface_Reconstruction_3" from CGAL library on CodeBlocks IDE on Ubuntu platform, as it would be nice
to have the IDE support for code completion and a more automatic configuration process.
I managed to successfully execute it by compiling it with cmake on the terminal window.
However, on CodeBlocks, after creating a new project and copying the code from the example, I get the following error:
/usr/local/include/CGAL/Scale_Space_Reconstruction_3/Scale_Space_Surface_Reconstruction_Impl_3.h:165:23: error: variable or field 'pca' declared void
Approximation pca( _nn[i]);
By looking inside the code, I found out that this is due to an undefined Macro CGAL_EIGEN3_ENABLED. As my experiment shows, if I define the macro at
pre-processing time, I do not get the same error. That is because, by defining the macro, the type definition Default::Get< wA,void>::type, becomes
Default::Get< wA, Weighted_PCA_approximation_3<Gt>>::type, and the compiler does not complain any more.
Unfortunately, as a deserved prize for messing with things I do not really understand, I get a segmentation fault at runtime.
How should I change the compiler options of codeBlocks to make the compilation succeed, and the executable run successfully?
I have the following include paths:
/usr/local/lib/CGAL/ /usr/local/include /usr/include /usr/include/eigen3.
I also included the following libraries:
libCGAL.so, libCGAL_Core.so, libCGAL_ImageIO.so, libgmp.so, libmpfr.so, libtbb.so, libtbbmalloc.so, libtbbmalloc_proxy.so
I'm fairly new to Xcode and have recently gotten an error message that is probably clear to anyone who knows what they're doing, but I am unsure how to react to this one.
I have a project that is mostly C++, with just a few C files in it. Everything was fine until I tried to add some code to find the computer's MAC address. Apple provides a project example (GetPrimaryMACAddress), and I downloaded, built, and tested that. It works just fine.
After that, I simply copied the C source from the Apple example project and included it into my code project. Then I started getting this error message:
I have tried including the IOKit framework explicitly via the linker; no help. I tried adding more #include statement to the Apple example code; no help. I think that I do not understand what the compiler message is telling me regarding importing from module 'Darwin.MacTypes'.
Clicking on the error message took me to a line in usr/include/MacTypes.h:
I'm not clear on how to Import Darwin.MacTypes. I don't really understand how the source code for GetMACAddress could compile so effortlessly in one project and not another. I didn't rearrange nor add nor delete any of the #include statements in the Apple-supplied C file.
I'll bet there is a simple answer that I am just not seeing. How should I react to this error message?
I had a similar problem with types like UInt16 and UInt32. I just included the MacTypes with the following include statement:
#include <MacTypes.h>
This solved all my type-problems for my example c-file.
Let me guess, when you want to compile C++ source, you should create a C++ source file
(On the toolbar: File > New > File.. > Source > C++ File)
I was about to use PuTTY Development source code for Windows to create my own client application (found here: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html) but as I tried to compile the PSCP project (SCP Client), I got the following error :
C:\work\2015\Putty\windows\version.rc2 (18): error RC2104 : undefined
keyword or key name: BINARY_VERSION
I've been going through the various posts involving this error but didn't find anything working :
error RC2104: undefined keyword or key name: DS_SETFONT :
On this post I noticed that the version of MSVC was brought up so I figured maybe something has to be done to get PuTTY to work on VC 6.0 ?
Also I tried to add #include <windows.h> in both version.rc2 (version.rc2 is used for inclusion in all .rc files) and pscp.rc, none worked.
I'll be quick to answer if you need any information (project properties, source code...)
USING Visual Studio 6.0 with SP6 on Windows 8.1
Probably, wrong version.h is seen.
Correctly, the file version.h in the project folder should be seen.
Please try to modify version.rc2:
#include "version.h"
to
#include "..\\..\\..\\version.h"
At least, resource compiler will end successfully.
If you search through the PuTTY source files, you'll notice that BINARY_VERSION is defined in version.h and used in windows/version.rc2, which #includes version.h.
Since your version.rc2 isn't seeing version.h, try to figure out why: Is version.h still present and does it still contain BINARY_VERSION? Are your include paths correct? Is there another version.h somewhere else in your include path that's getting picked up by mistake?
Which source code are you using ?
I tested latest(0.64) "Release source code for Windows".
direct link is
http://the.earth.li/~sgtatham/putty/latest/putty-src.zip
I had tried to compile using VC++ 6.0 Professional with SP6, on my PC,
running Windows XP SP3.
After extracting putty-src.zip to somewhere with keeping folder
structures, did you correctly opened 'putty.dsw' in "putty-src\windows\MSVC" folder?
You should be find in 7 projects in 'FileView' tab of the workspace
in Visual Studio 6.0.
You can switch active project to 'pscp' with context menu via
right button click on 'pscp' project.
With modified version.rc2, resource compiler finished successful.
But two (sshshare.c, winsftp.c) C source files failed compiling
with 20 errors. in 'pscp' project.
Errors while compiling 'winsftp.c' is caused 'TIME_POSIX_TO_WIN'
and 'TIME_WIN_TO_POSIX' macros.
'ull(unsigned long long)' is a 64-bit integer-suffix, newly defined in C99. Since C99 standard is not support on VC6, then caused errors.
I had temporally modified
11644473600ull ------> ((ULONGLONG)11644473600)
10000000ull ---------> ((ULONGLONG)10000000)
and confirmed errors are cleared. (Sorry, no validation the code is correctly generated)
3 errors while compiling 'sshshare.c' is also caused another macro.
I cannot understand why you got 116 errors.
I am running 64bit Linux and using Netbeans 8.0 IDE. I simply created new C++ project, so far only containing some HelloWorld code. I want to use a third party library for logging. I chose log4cpp (since I have experience with Java and it is supposed to have similar interface).
I installed liblog4cpp from the repositories, and can see it in /usr/lib, to be clear:
$ locate log4cpp
/usr/lib/liblog4cpp.so
/usr/lib/liblog4cpp.so.5

I am having big trouble on how to #include it in my application. Inspired by example from the documentation I put in my source:
#include "log4cpp/Category.hh"
#include "log4cpp/Appender.hh"
#include "log4cpp/FileAppender.hh"
#include "log4cpp/OstreamAppender.hh"
#include "log4cpp/Layout.hh"
#include "log4cpp/BasicLayout.hh"
#include "log4cpp/Priority.hh"
I was first using Makefile generated by netbeans, however could not figure out how to configure the project to make it work. All my trials lead to the following error (line 16 being the first #include):
$ make
src/main.cpp:16:31: fatal error: log4cpp/Category.hh: No such file or directory
compilation terminated.
make: *** [build/NetworkConfiguration.o] Error 1
I also tried a custom Makefile, giving g++ argument -llog4cpp, but I always get the same error. I can provide more info/code if it will be helpful. The solution does not need to depend on the IDE, I feel like I just misunderstood how linking works, so feel free to educate me on how to achieve what I want from console with custom Makefile for example.
Since cup still has not posted an answer, I am paraphrasing his comment as an accepted answer.
Install liblog4cpp-dev. The difference is that liblog4cpp only contains the libraries while liblog4cpp-dev is the development kit which includes the headers.
