I want to use GCG's branch-and-price frame to solve a MIP which is similar to Binpacking problem. So I download the SCIPOptSuite-6.0.0-win64-VS15.exe and install it in Windows 7 and then install the Visual C++ Redistributable Packages which is required. Also I install the Cmake in Windows 7. But I do know how to do next after failed trying the instructions in the website https://scip.zib.de/doc-6.0.0/html/CMAKE.php (Installation information using CMake (recommended for new users)). I do not know where to start to compile. I even do not know whether the installation succeeds or not.
If you want to compile the code, you need to download the source package not the precompiled ones, as they don't include the source files.
As far as I know, GCG is not available in the precompiled packages, unfortunately.

I'm attempting to build TensorFlow's C++ library for Windows XP. While I've been able to build and use it on Windows 10, 32-bit XP isn't working. The background: I'm working on a COM module that calls fuctions from tensorflow.dll. My build environment:
Visual Studio 2017 15.7
CMake 3.11.1
TensorFlow 1.8
Windows 10
The sequence I use to build tensorflow.dll is:
Open "x64_x86 Cross Tools Command Prompt for VS 2017"
Try to force the use of functions availablbe in Win XP: set CXXFLAGS=/D_WINVER=0x0501 /D_WIN32_WINNT=0x0501
Add Git to path: set PATH=%PATH%;C:\Program Files (x86)\Git\bin
Fix CMake file for converting *.proto files to *.pb.h files as described here.
Configure CMake: cmake .. -A Win32 -T v141_xp,host=x64 -DCMAKE_SYSTEM_VERSION=7.0 -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=C:\Users\williams\AppData\Local\Continuum\Anaconda3\envs\tensorflow\python.exe -Dtensorflow_BUILD_SHARED_LIB=ON -Dtensorflow_BUILD_PYTHON_BINDINGS=OFF -Dtensorflow_WIN_CPU_SIMD_OPTIONS="/arch:IA32"
Build: cmake --build . --target tensorflow --config Release -- /fileLogger /m:1 /p:CL_MPCount=1
The last step also involves some manual labour as the build process doesn't copy .lib files from the 3rd part dependencies to where they are needed. For whatever reason, a bunch of INSTALL projects never get run so I had to do that manually each time the build would fail while looking for a missing lib file. Once that was done, the build completed successfully.
Next I copy my COM module (a DLL) and the TensorFlow DLL over to a Windows XP virtual machine for testing and try to register the COM module, but get an error LoadLibrary("MyDLL.dll") - The specified procedure could not be found. I don't know what procedure it is looking for, so the best I can offer is that Dependency Walker highlights WS2_32.DLL and tells me it can't find inet_ntop and inet_pton.
Any suggestions on how to build TensorFlow so that it doesn't use these two functions?
P.S. suggestions of "Stop using XP, its old and no longer supported" don't help here. Upgrading to Windows 10 is an absolute last resort because of the disruption it would cause at the facility where this software will be tested.
Edit 1:
These two functions inet_pton and inet_ntop were only used in one file that forms part of Google Cloud Storage support in TensorFlow. The build process generated a tensorflow_static.lib in addition to tensorflow.dll. Linking against the static version and adding a few dependencies that aren't included in tensorflow_static.lib got rid of the code using inet_* functions.
My COM module still isn't working on Windows XP though because the file tensorflow\core\platform\windows\env.cc uses functions like CloseThreadpoolWork, submit SubmitThreadpoolWork, etc. that were only introduced in Windows Vista. It looks like I'll have to replace them with something else, as I don't see an alternative implementation in TensorFlow.
Additionally, I found that tensorflow\contrib\cmake\CMakeLists.txt forces _WIN32_WINNT=0x0A00 and that CXXFLAGS is the wrong environment variable to use. Changing it to CMAKE_CXX_FLAGS at least gets my macro definitions included, FWIW.
It is almost impossible to port tensorflow to windows xp, because:
TF's platform depedent code requires some Windows APIs later than winxp such as Thread Pool API. This would possibly bypassed by using third party thread pool libs.
The nsync, protobuf and eigen, which are core parts of TF, use C++11 thread_local, which makes them unable to run-time load as dll, see https://learn.microsoft.com/en-us/cpp/parallel/thread-local-storage-tls?view=vs-2017 for details. This later feature can theoretically be replaced by old windows TLS API, which requires many modifications on TF's core framework.
Anyway, if you really need the xp support, good luck with that.
In the end I gave up on this as simply being impossible. Even replacing the thread pool functions with something from Boost didn't help. If someone else manages to get this working, I'll gladly accept that as the answer, but so far this looks impossible.
I have recently started GUI development using wxwidget using C++ and MinGW.
Do I need to install wxWidget library separately when I download the wxFormbuilder?
Yes, you need wxwidgets installed to work with formbuilder. I suggest you to install codeblocks with mingw which you can find http://www.codeblocks.org/downloads/26 and follow this link https://wiki.wxwidgets.org/CodeBlocks_Setup_Guide to compling wxwidgets. When you are installing formbuilder for the first I guess it will ask for the location of wxwidgets installed directory so you need to have this or else you can setup this later.
Let me know if you have queries
I want to use KDL (Kinematics and Dynamics Library) in robot control box. But robot control box uses SCons as their build system while KDL uses CMake.
It turned out that the control box doesn't have CMake installed. Should I install CMake in the control box? Or write SCons file for compiling KDL?
====================================================
My question is ambiguous. Sorry for that. And unfortunately, I cannot show the link of Control Box, it's not public. Here is link of KDL installation manual.
http://www.orocos.org/kdl/installation-manual
Let me make it more clear.
Forget all of previous question above and all about Control box, KDL. Let's say that you want to use one library. But the library can be built using CMake according to installation manual. Your PC doesn't have CMake installed but it has SCons, and unfortunately you should not install CMake on your PC.
If you can only use SCons, what can you do?
I know this situation is not usual, I want to know your opinion.
To answer your initial question: Yes, you should always try to install CMake, if that is a build requirement for you library and if you need to build that library from the sources.
To answer your later question: Replacing or rewriting the build system scripts is a major effort and not advisable. In general there is no script to convert build-systems. Such script might help to make the manual transformation. If you have a look at LLVM's effort to replace Autotools by CMake or Boost replacing it's own build system by CMake, you find out it takes several people several years and still not everybody is satisfied.
Often you don't need to build the library yourself. Either there are already built packages from the project directly of from your distribution (Debian etc. packages) or third party packagers like Mac Ports or NuGet.
In your case KDL provides Debian/Ubuntu packages.
Additional KDL is part of ROS, which is experimental in Homebrew for OS X.
there!
I'd like to execute example program, Surface_reconstruction_points_3.
I think the program needs additionally 3rd library, MPFI.
So I downloaded the library from http://mpfi.gforge.inria.fr/.
And I unzipped it at proper folder and linked it to the system path.
After configurating the example program using cmake-gui,
I found some error message, 'Could NOT find MPFI (missing: MPFI_LIBRARIES)'.
How can I install MPFI library in Window using visual studio 2008?
Since MPFI is a GNU library, it is completely supported on Windows.
CGAL provides this third-party libraries inside its installation, but Windows has its own replacement.
I installed this correctly with Visual Studio, but you need to uncheck those third-party libraries so CGAL won't mess with the own windows replacements.
Maybe doing this kind of installation isn't working well for all the sample codes inside the installation, but it works fine for development. I used CGAL without those third-libraries for Voronoi and 2D and 3D triangulation and it works fine.
For a clean installation, delete all you installed previously, make sure the new installation isn't messing with the bad previous installation.
EDIT:
About not using those optional libraries for Windows, I just received a similar mail through the CGAL mailing list and these could be the steps for newer versions of CGAL (>4.2):
You have to comment 3 lines in the CMake machinery:
In CGAL-4.1/CMakeList.txt you have to comment:
#list (INSERT CGAL_ESSENTIAL_3RD_PARTY_LIBRARIES 0 GMP MPFR)
#hide_variable(CGAL_ESSENTIAL_3RD_PARTY_LIBRARIES)
In CGAL-4.1/cmake/modules/UseCGAL.cmake you have to comment:
#use_essential_libs()
On the other hand, you can search on internet for precompiled versions of MPFI. For instance, you can find precompiled GMP, MPFR and MPFI for Windows on http://vegas.loria.fr/rs/ .
After an upgrade to the new Haskell Platform, my existing wxHaskell programs are broken.
They all seem to now require wxWidgets 2.9, for which I can't find any binary versions.
wxPack has 2.8, and beyond that one has to get a compiler and build it locally from what I see.
There are tutorials on this from various sources, each a few pages long, with various advice on setup, changing configurations, etc. Install wxConfig, install minGW compilers, setup configurations, rebuild, etc.
Is there any source of a simple binary install? I'd hope for some simple apt-get or cabal like tool, Haskell library tools (on Windows?) seem less integrated than others that I'm familiar with.
(Update) I did install and compile wxWidgets locally, and still cannot get the wxHaskell components to install. I'm sure that all of this just requires some fairly simple details, but again after some time already, hope not to have to spend a lot more time on this, and wish it was more automated!
Configuring wxc-0.90.0.3...
Configuring wxc to build against wxWidgets 2.9
setup.exe: Missing dependencies on foreign libraries:
* Missing C libraries: wxmsw29ud_all, wxtiffd, wxjpegd, wxpngd, wxzlibd,
wxregexud, wxexpatd, wxregexud
This problem can usually be solved by installing the system packages that
provide these libraries (you may need the "-dev" versions). If the libraries
are already installed but in a non-standard location then you can use the
flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are.
cabal: Error: some packages failed to install:
wx-0.90.0.1 depends on wxc-0.90.0.3 which failed to install.
wxc-0.90.0.3 failed during the configure step. The exception was: ExitFailure 1
wxcore-0.90.0.1 depends on wxc-0.90.0.3 which failed to install.
Yes, you can. CodeLite (C++ IDE I use) was recently upgraded to use wx29.
Since there are no binaries yet on repo, Dave set up some. Find all instruction in CodeLite's wiki below
wxWidgets 2.9 Packages and Repositories
If you are using windows Just go to download page for Codelite and download codelite with wxWidgets. Install it, copy the installed wxWidgets directory wherever it is needed!
Also it seems like there are official binaries. I have never tested download anything there so try yourself. The link is this one
