I have a piece of code that uses boost's unordered_set
#include <boost/unordered_set.hpp>
boost::unordered_set<string> mySet(100);
It compiles and works fine with gcc under unix. When I try cross compiling with mingw32 (gmake 3.8.1) I get the following message:
In file included

To me it seems like a template related problem; any suggestions?
Thank you,

[EDIT]
other boost functionalities are available, for example the lexical cast
#include <boost/lexical_cast.hpp>
It seems that some typedef breaks the boost cstdint header, which looks like
103 using ::int8_t;
104 using ::int_least8_t;
105 using ::int_fast8_t;
106 using ::uint8_t;
107 using ::uint_least8_t;
108 using ::uint_fast8_t;
on my system. So, some hero probably defined "#define uint8_t" instead of "typedef ... uint8_t", and this code consequently breaks.
You might try to to modify your boost/config/platform/win32.hpp and, if that helps, report the bug to the mingw developers.

I'm following this guide but when I try to build the c++ library I get the following fatal error.
../../../../gcc-11.1.0/libsanitizer/asan/asan_linux.cpp: In function ‘void __asan::AsanCheckIncompatibleRT()’:
../../../../gcc-11.1.0/libsanitizer/asan/asan_linux.cpp:199:21: error: ‘PATH_MAX’ was not declared in this scope

This appears to be a bug in libsanitizer/asan/asan_linux.cpp. It seems to find the wrong limits.h file.
I was able to work around it by modifying asan_linux.cpp as follows.
-#include <limits.h>
+#include <linux/limits.h>
after uncommenting in typemap.dat the following line:
xsd__dateTime = #import "custom/chrono_time_point.h" | xsd__dateTime
I run wsdl2h and everything is fine..
but later in soapcpp2 I'm getting the following warning:
custom/chrono_time_point.h(70): *WARNING*: invalid type specified (missing ';' or type name used as non-type identifier?)
what is this?
Edit
I use gsoap windows from vcpkg.
You do not need to #include "custom/chrono_time_point.h" in your code base after adding that line to your typemap.dat. Adding this line suffices to use std::chrono::system_clock::time_point for XML xsd:dateTime values.
Note that #import custom/chrono_time_point.h is used by soapcpp2 to register the std::chrono::system_clock::time_point serializer.
The serialization implementation is custom/chrono_time_point.cpp which should also be compiled together with the project.
I was working on a project and got the following errors
Error (active) the default constructor of "Input" cannot be referenced -- it is a deleted function EquationSolver c:\Users\Kim\Documents\Visual Studio 2015\Projects\EquationSolver\EquationSolver\main.cpp 10
Error C2280 'Input::Input(void)': attempting to reference a deleted function EquationSolver <project_dir>\main.cpp 10
Since it is almost impossible to find the cause of the error from this, I tried compiling with gcc with -Wall and got following output
main.cpp: In function 'int main()':
main.cpp:10:9: error: use of deleted function 'Input::Input()'

This output is much more verbose and quickly helped me find the origin, which was a misplaced & (class member should be Vec left, was Vec& left).
Is it possible to make Visual Studio as verbose?
When putting Visual Studio to /Wall, I get >1800 warnings, most completely unrelated to my project, but I still only get those two errors.
I am trying to use the Capacitive Sensors Library from the Arduino Playground with Arduino 1.5.3 for Intel Galileo.
While trying to compile the example Sketch of the library with nothing touched I get the following error:

I downloaded the files and imported the "CapacitiveSensor"-Folder into (I did those steps one after the other, not at the same time.):
The libraries folder under Documents/arduino/.
The libraries folder in the arduino folder where the arduino.exe is stored.
Onto arduino-1.5.3/hardware/libraries/ (because this is mentioned on the site where I downloaded it)
And I tried this: Here Because it seemed to be the same error as I had. But it didnt work.
I also deleted my Arduino and reinstalled it.
Anyone has an Idea?
Thanks in advance,
Clemens
There is a similar question on the Arduino forum but I don't know if your issue is exactly the same: [FIXED][CapacitiveSensor] Can't compile with Due (port manipulation)
It doesn't look like the Arduino folks are very responsive. The user modified register names and eventually put his own library out there.
*"...changed the uint8_t registers to RwReg (compiler doesn't complain) and I replaced the use of portModeRegister(PIN) with simple pinMode(PIN, MODE) calls (it's slower but it works)."*
Hopefully this is more relevant to StackOverflow than mac.stackexchange...
I am using ARToolkit for an augmented reality project, and in order to make it work under Mac I need to run the 10.5 SDK.
My problem is that I cannot seem to include any of the STL header files...especially vector.
Is there any sort of wrapper or workaround that I can use? I am basically compiling straight C code, and would like to make use of some of the nicer features of the STL framework to speed up development...
Edit:
In closer inspection, it appears that ARToolkit is including std_vector at some point in its include path.

You might need to make your file a .mm file (Objective-C++) instead of .m (Objective-C).
Other than that, there shouldn't be any trouble doing #include <vector>.
Basically, there was some trickery that had to be done behind the scenes.
I had to update my local SDK (turns out that ARToolkit does support newer versions, regardless of what THEIR documentation says), and then the STL libraries worked.
