missing payoffs.hpp and other .hpp from version - windows

When building the Windows C++ version of quantlib 1.9.1, I get this error of missing payoffs.hpp. When I browse to the directories, I see payoffs.cpp, but not payoffs.hpp:
Severity Code Description Project File Line Suppression State
Error C1083 Cannot open include file: 'ql/instruments/payoffs.hpp': No such file or directory FittedBondCurve c:\users\administrator\google drive\quantlib-1.9.1\ql\cashflows\conundrumpricer.hpp 27
I also get this for #include <ql/instruments/swap.hpp> [and possibly others]. I am able to build the windows quantlib library ok. Just not the examples.

I just checked the QuantLib 1.9.1 release available from the project downloads (did you get your version from there?) and the files you're looking for are contained in the release zip and tarball. Also, it's pretty weird that you could compile the library without them, so I'd double check if they're there. If they really aren't—well, hard to know how they got displaced; anyway, you can download the release again and replace them. If that doesn't fix the problem (or if they're already there after all), it's possible that you have to fix the include path for the example you're trying to compile. Does it include the QuantLib directory?

Linking my CMAKE project with libpng in Windows

I'm working on a C++ project that requires libpng. So far I've worked on Linux and everything is smooth. I installed libpng, CMAKE picks it up and everything is alright. Now move to Windows.
Here I first installed zlib (required by libpng) and libpng. When I say install, I mean I downloaded the source files, and then built them and install them using msbuild.
I noticed that by doing so, I got new folders under c:\program files (x86):
c:\program files (x86)\zlib
c:\program files (x86)\libpng
Seemed all right to me. Now when I configure my project with CMAKE zlib is picked up:
-- Found ZLIB: C:/Program Files (x86)/zlib/lib/zlib.lib (found version "1.2.13")
but there's no way CMAKE finds the PNG library:
Could NOT find PNG (missing: PNG_LIBRARY PNG_PNG_INCLUDE_DIR)
Now I tried to have a look at the FindPNG and I noticed this line:
find_path(PNG_PNG_INCLUDE_DIR png.h PATH_SUFFIXES include/libpng)
Does this mean that CMAKE expects the file png.h to be in a directory ending in include/libpng? If so, then it will never find it because in my case png.h is placed in libpng/include. But this is also the "official" installation from the source code just downloaded from http://www.libpng.org/pub/png/libpng.html.
So now I am superconfused. How things are supposed to work in Windows? Should I "create" a folder structure with the correct files for every library so that CMAKE is happy? In a way I hoped things in Windows were similar to what happens in Linux: libraries go in a standard folder, they are detected by CMAKE.. everything is ok. But apparently this is not the case. So my question in general is: how do you ship a package like this to a Windows user so that he can builds it without having to go through all this?
Thanks so much
Fabrizio
This would be the right one to use:
find_package(PNG)
You can tell CMake to look in the location where you installed it by adding the libpng base install location to CMAKE_PREFIX_PATH. Without this, CMake doesn't know where you put it.
cmake "-DCMAKE_PREFIX_PATH=C:/Program Files (x86)/libpng" ...
Note that FindPNG first looks for zlib and will fail if zlib could not be found.

Visual studio and dlib: "cannot open include file: 'zlib.h': No such file or directory"

For my thesis I want to use Dlib's face_landmark_detection, but I keep running into these errors (for both Visual studio 2013 as well as 2015):
"cannot open include file: 'zlib.h': No such file or directory"
and
"'F77_INT': undeclared identifier".
It repeats itself so I have 36 errors based on these two problems.
My supervisor has given me some steps to follow to set up the project:
add dlib-master and dlib-master\examples to VC++ directories -> include directories
add dlib-master\dlib\external\libjpeg and dlib-master\dlib\entropy_decoder to C/C++ -> General -> Additional include directories
add all folders and items from dlib-master\dlib\external (cblas, libjpeg, libpng and zlib) to the project source folder
add the dlib source file (from dlib-master\dlib\all) and add face_landmark_detection (from dlib-master\examples) to the project source folder.
and according to him this has worked on every other computer so far, but on my laptop it just won't. We checked to project, but zlib.h is in the zlib folder in the project. Does anyone here have an idea on what might be going wrong?
If I didn't give enough info, please ask. I don't know what else might be needed to solve this.
I have just come about this same problem and wanted to post my solution since I have found so much conflicting documentation on the subject.
The folder containing the dlib folder as well as the libpng, libjpeg, and zlib folders from dlib/external need to be added to the additional include directories list in the solution settings.
dlib/all/source.cpp as well as the source files for libpng, libjpeg, and zlib also need to be added to the project.
Note that CBLAS should not be added to the project in any way, because it needs Fortran to compile, and it is very difficult to get this to compile from Visual Studio.
Finally, make sure to add DLIB_PNG_SUPPORT and DLIB_JPEG_SUPPORT as preprocessor defines in the project settings.
I also attempted to use a cmake generated solution, however, for some reason it had trouble with png support.
It is probably easiest to use CMake to configure your project which uses dlib. It avoids setting all those paths manually. During CMake configure step you can disable usage of libraries like zlib which you don't have/want/need. Here is an example CMakeLists.txt which works for me:
cmake_minimum_required(VERSION 2.6)
PROJECT(DatasetClassifier CXX C)
set(dlib_DIR "" CACHE PATH "Path to dlib") # http://dlib.net/
include(${dlib_DIR}/dlib/cmake)
ADD_EXECUTABLE(DatasetClassifier DatasetClassifier.cpp)
TARGET_LINK_LIBRARIES(DatasetClassifier ${dlib_LIBRARIES})

freeswitch noob cant build solution

im just starting out with FreeSwitch, i downloaded via git, and am trying to build in VS
all i need i believe are the dlls of mod_managed, as my goal is to manage FS via .net
but i get 248 errors, most look something like this:
Error 5 error C1083: Cannot open source file: '....\jpeg-8d\jaricom.c': No such file or directory D:\FreeSwitch\freeswitch\libs\win32\libjpeg\c1 libjpeg
btw, i searched windows and cannot find any such file anywhere on my pc.
I tried
cleaning the solution first, but it did not help
moving the file to a path without spaces
downloading with autocrlf=false
building on another machine
but none of these steps helped
anybody have any idea?
if i can just download the dlls i need, i wouldnt mind skipping this step altogether
environment
win 8 64bit
visual studio 2012
thanks a million
The libjpeg sources are not in the git sources but are normally downloaded during the build process. If you build the entire solution that should not be a problem since it has the project dependencies set: libjpeg.2012 depends on Download libjpg.2012, which means the latter gets built before the first. All Download libjpg.2012 is run a cscript which downloads libjpeg from http://www.ijg.org/files/jpegsrc.v8d.tar.gz (see inside the project file).
So if you do not have the sources, either you are building incorrectly (not in VS for instance, or with a broken solution file) or the download script is broken. In that case, you should inspect the output: I assume it shows errors when it can not download the libs.

qmake gives code 3 when attempting to configure qt for static building

I have the latest Qt SDK. I'm trying to configure it for static building with VS2010 (dynamic linking works fine) I have it at this location: C:\QtSDK\Desktop\Qt\4.8.0\msvc2010
When I go there with the VS2010 command prompt and try to run configure -static, or configure -static I get some output but in the end it fails with

I downloaded the source zip file instead of trying to work with what came in the SDK and it's working now. Just download the source from here, unzip it, and run the configure.exe in the unzipped folder. My guess (although I have inspected this) is that there's missing source files or other resources in the SDK version.

How to build wxWidgets 2.9.1 with Visual Studio 2010?

I have a freshly downloaded Visual Studio C++ 2010 Express and wxWidgets 2.9.1. The build folder under wx\build\msw has solution files for VC++ versions 6 through 9 (2008).
I tried to open the latest solution, wx_vc9.sln. It converted all the projects with a bunch of warnings. When I try to build every project gets the error:
C:\Program Files
(x86)\MSBuild\Microsoft.Cpp\v4.0\Microsoft.CppCommon.targets(151,5):
error MSB6001: Invalid command line
switch for "cmd.exe". The path is not
of a legal form.
Trying to open the previous version of the solution, wx_vc8.sln, generates the same conversion warnings and the same build errors.
I Googled for some hints and found a suggestion to start with the .dsw file. I opened wx.dsw and it generated an error for each of the project files:
D:\3rdParty\wx\build\msw\wx_wxregex.dsp
: error : Project upgrade failed.
Finally in desperation I tried nmake /f makefile.vc and was greeted with yet another error:
NMAKE : fatal error U1077: 'cl' :
return code '0xc0000135'
Anybody have any hints? Thanks.
There are two ways of solving this, firstly if you update to a more recent version of the wxWidgets SVN trunk this is fixed (and so it will be fixed in 2.9.2 when it is released). If you don't want to work from trunk of wait for 2.9.2 then if you do a find and replace over all .vcxproj files and replace
>$(INTDIR) $(OUTDIR);%(AdditionalInputs)
with
>%(FullPath);%(AdditionalInputs)
it should then compile fine.
For future reference, trust me people, avoid all nonsense and start up your Visual Studio 2010 Command Prompt and navigate to [wxwidgets directory]\build\msw
Then compile using the makefile with the following command :
nmake -f makefile.vc BUILD=release MONOLITHIC=0 SHARED=0 UNICODE=1
Of course change the options as needed.
You will be saving a lot of trouble this way, this is the way I did.
The Key to Compilation using Visual C++ 2010 Express and wxWidgets 2.9.3 is to keep Pressing F7 Again-and-Again-and-again.... till you you get '0 Failed' Message below. Because many Projects have dependencies which are not satisfied immediately, so it is necessary to keep compiling with 'F7' till all are satisfied.
Download wxWidgets. I downloaded the .7-Zip File (only 12 MB ! ), and installed it at C:\wxWidgets The Structure should be like so that you see the following Folders like C:\wxWidgets\lib and C:\wxWidgets\build etc etc...
Basically the process should be to go to C:\wxWidgets\build\msw , and open wx_vc9 Solution File for VC-2008, and convert it to VC-2010 when asked. Then Choose 'DLL-Release Win32' on Top, and Press F7. Wait for Compilation to take place and see the Message. Then keep Pressing F7 again and again till you get '0 Failed' Message below. Then you would want to Compile 'DLL-Debug' Release in the same manner.
The compiled DLL Files can then be found at C:\wxWidgets\lib\vc_dll. Now, To Add vc_dll Folder to your PATH, Right-Click on My-Computer -> Properties -> Advanced System Settings -> Environment-Variables -> User-Variables. Search for 'Path' -> 'Edit', and then Just Append ;C:\wxWidgets\lib\vc_dll to the End.
This makes running your compiled Application easier, as your .EXE can now easily find DLLs.
When you are packaging, then you obviously need to bundle specific Release-DLL'S along.
Then you can compile the Samples located at C:\wxWidgets\samples.
I just go to individual Project Folder, like for e.g. C:\wxWidgets\samples\drawing, and Open drawing_vc9 Project, then Convert it as Prompted, and then hit F7 to create Release Version. Now if you go inside C:\wxWidgets\samples\drawing\vc_mswudll\ Folder, you have your 'drawing.exe' ready-to-be-run !
Have fun !
Use the wx.dsw, took me a while to finally get it but it'll build fine after that. I also suggest using one of the sample projects such as 'minimal' as the base and just fix all the config paths to match what you want to build (as manually setting up I encountered issues).
If you already used the wx_vc9 (like you said you did) you are probably best off just deleting all of wx and restarting with it and using wx.dsw like I said above.
