I'm trying to use emscripten Embind to bind C++ functions to JavaScript. Unfortunately I already get compile errors when including the specific header file with #include <emscripten/bind.h>.
I checked my emscripten environment and set an additonal Include Directory in VS2013 to the absolute path of the installation folder (also tried $(EMSCRIPTEN); and adapted the inlcude statement).
When compiling my project, I get 20+ compile errors:
17>d:\program files\emscripten\emscripten\1.25.0\system\include\emscripten\wire.h(24): error C2144: syntax error : 'bool' should be preceded by ';'

17>d:\program files\emscripten\emscripten\1.25.0\system\include\emscripten\wire.h(54): error C2146: syntax error : missing ';' before identifier 'TYPEID'
...
I tried emscripten 1.22.0 and 1.25.0 and verified my emscripten environment following those instructions. What am I missing?
As far as I know, of the MS Visual Studio editions, only VS2010 is supported in Emscripten.

I am trying to compile qwt 6.1.3 with QT 5.15.2 which came with QT 4.11.0. When I run run qmake it compiles fine. However, when I run Build I receive 10849 errors which look like missing C++ libraries.
The first errors I get are:

There is a triangular mesh generator (Shewchuk, CMU), "Triangle", that are recommended by people due to its lightweight. It is written in C. However I cannot use it in my VS2012 C++ project. I am compiling it using x64 platform. I am on Windows 7 64-bit.
Basically, I compile the triangle.c as the makefile described. So, a triangle.o is generated. I then
added triangle.o as additional dependencies in my solution,
added triangle.c and triangle.h in my project .
changed triangle.c in C/C++ precompiled header option, to "not using precompiled header"
Then I got tons of errors like this:
1>C:\Program Files (x86)\Windows Kits\8.0\Include\um\winnt.h(430): error C2143: syntax error : missing ';' before '*'

I am just wondering, is there anyway to make the triangular mesh generator work with VS2012 C++ project? If so, what is the right way to set it up on VS2012 C++ x64?
You might want to have a look at this: Compilation errors of a simple C++ project in VS 2012.RC 4
disable pre-compiled headers, and delete the pch file from the intermediate directory.
This initially didn't work for me, so I tried moving #include at the top of the file, before all other includes, and this worked for me.
I would like to create a project use to call c++ method using c#. So, I need to create a dll file for all of my c++ function. But when i get an error in y sqlite source code such as "AreFileApisASNSI undeclared identifier". So, i import winbase.h which is part of the mingw-w64 runtime package to my visual studio 2012 express DLL project. After import the file, I get many errors such as below:-
error c4430: missing type specifier - int assumed. Note: C++ does not support default - int
error C2143: syntax error : missing ';' before '_stdcall'
error c1003 error count exceeds 100; stopping compilation
error c2061: syntax error: identifier ' WINBOOL'
error c2086: 'int_CRT_INLINE' : redefinition
error c2143: syntax error: missing ';' before ''
error C2146: syntax error : missing ';' before identifier 'LONGLONG'
error C2146: syntax error : missing ';' before identifier 'PVOID'
any solution for those error? please help!!
The documentation for the function has this header requirement:
WinBase.h (include Windows.h)
This is telling you that the function is declared in WinBase.h, but that you should include Windows.h which in turn will include WinBase.h. So, you need to change your include to
#include <Windows.h>
I also wonder why you are talking about mingw considering that your compiler is MSVC. That compiler ships with a comprehensive Windows SDK. Why would you be using an SDK from mingw?
Hey Everybody,
I'm trying to SWIG a multi file project that I made in VS2010 (c++) to python. I've managed to link the Python26.lib file, and have SWIG generating a wrapper .cpp file for my main .cpp file. I've set my code to build a .dll with the extension .pyd.
This is the .i file I have currently:
%module HiveGPS
%{
#include "ou_thread.h"
#include "HiveGPS.h"
%}
%include ou_thread.h
%include HiveGPS.h
And I've mangaed to get a .py and .pyc file. Now, from my understanding in order to run my .py file, I need to link it to my .pyd file, but when I try to use VS2010 to build my project with the settings I listed above, it complains about a Thread class I'm using:

All of these errors (minus the last one) are basically saying that the String class is implemented somehow, is it conflicting with Python's definition of the String class? The last error is complaining about the Thread class, could that be the same problem?
All of that said:
Can somebody tell me what I'm doing wrong, or better yet, point me to a tutorial of how to do this for VS2010 (the SWIG site is for 2008).
And if that can't be done, can I link the .py file I have generated to the .dll file somehow?
Sorry for the long explanation but I'm kinda lost on this one so I decided to explain everything.
Ok, I'm using swig and VS2010 with no problems...
In your case, it looks more like you have problems with linking. Beyond the check of libraries, dont forget to check 32-64 bit libraries you are linking. Try to link all as x86 target as fail-safe. And don't use AnyCpu.
How to use SWIG under VS2010.
lets define you want to obtain mylib.py, so you created some SWIG interface files with mylib.i as "main" file. I assume that you already have a solution with project with your C++ classes there.
(1) First create C++ project for SWIG interface. Use Visual C++->Class library project which should create a C++ DLL stub. I put all .i files there. And set visual studio to highlight .i as .h - it is handy.
(1.1) Add mylib_wrap.cxx file to the project (create empty file while swig hasn't generated one yet)
(2)
a) Press right button over the mylib.i, choose properties.
b) set ItemType as "Custom build tool".
In custom build step window:
c) Command line field should be something like:
echo In order to function correctly, please ensure the following environment variables are
correctly set:
echo PYTHON_INCLUDE: %PYTHON_INCLUDE%
echo PYTHON_LIB: %PYTHON_LIB%
echo on
C:\swig\swig.exe -c++ -python %(FullPath)
change C:\swig\swig.exe to your path to SWIG
d) In Outputs field:
$(InputName)_wrap.cxx
(3) Go to this project properties:
a) C++ tab -> Additional Include Directories
add $(PYTHON_INCLUDE); ...
c) Linker -> Output File
Path-You-Needed\_mylib.pyd
d) Linker -> Enable Incremental Linking
set as No (/INCREMENTAL:NO)
e) Linker -> Input -> Additional Dependencies
add $(PYTHON_LIB);...
f) C/C++ -> Precompiled Headers:
Switch off precompiled headers, set **Not Using Precompiled Headers* and remove stdafx files after
g) General tab. Just check that these are set:
Configuration type = Dynamic Library (.dll)
Character set = Use Unicode Character Set
Common Language Runtime Support = No Common Language Runtime Support
It compiles.
P.S. And dont forget to set %PYTHON_INCLUDE% and %PYTHON_LIB% variables in your system too.
It seems that some #include is missing in the ou_thread.h.
Further more, the "'class' type redefinition" can indicate that you don't have something like
#ifndef __ou_thread_h__
#define __ou_thread_h__
// your stuff, classes, etc.
#endif
in your ou_thread.h
It's a guessing...
I have compilation errors while compiling MySQL sample of storage engine from MySQL 5.1.36 sources. Looks to me that I set all paths to include subdirectories but that seems not enough.
Here are the errors:
1>c:\users\roman\desktop\mysql-5.1.36\sql\field.h(1455) : error C2065: 'FRM_VER' : undeclared identifier
1>c:\users\roman\desktop\mysql-5.1.36\sql\item_cmpfunc.h(1395) : error C2146: syntax error : missing ';' before identifier 'preg'

1>c:\users\roman\desktop\mysql-5.1.36\sql\item_cmpfunc.h(1395) : error C4430: missing type specifier

I had to include mysql_version.h.in library that contain all appropriate variables like FRM_VER, etc. That resolved the errors metioned above.
