I have installed pycparser that parses C code.
Using pycparser I want to parse an open source project, namely PostgreSQL(version-11.0). I have build it using Visual Studio Express 2017 compiler suite. However, during compilation it cannot find some header files, namely windows.h and winsock2.h.
While looking at the directory structure of the build PostgreSQL, I find that it does not have these header files. How to fix this issue?
Also a strange error occurred as:
postgresql/src/include/c.h:363:2: error: #error must have a working
64-bit integer datatype
Note: I am using Windows 10 64-bit platform and postgresql-11.0
The steps are as follows:
I downloaded visual studio 2017, Windows-10 SDK, Active Perl as described in the steps to build from source in PostgreSQL.
After this I open the developer command prompt of Visual Studio and navigate to the folder postgresql-11.0/src/tools/msvc
Use command "build" to build postgresql. The build process was successful, but still windows.h and winsock2.h was not found in directory structure of PostgreSQL.
I don't know pycparser, but your problem probably has two aspects to it:
You didn't give pycparser the correct list of include directories. The header files you mention are not part of PostgreSQL.
Maybe you can get the list from the environment of the Visual Studio prompt. I don't have a Windows here to verify that.
The error message means that neither HAVE_LONG_INT_64 nor HAVE_LONG_LONG_INT_64 are defined.
Now pg_config.h.win32, which is copied to pg_config.h during the MSVC install process, has the following:
#if (_MSC_VER > 1200)
#define HAVE_LONG_LONG_INT_64 1
#endif
Since you are not using MSVC, you probable don't have _MSC_VER set, which causes the error.
You could define _MSC_VER and see if you get to build then.
Essentially you are in a tight spot here, because pycparser is not a supported build procedure, so you'll have to dig into the source and fix things as you go. Without an understanding of the PostgreSQL source and the build process, you probably won't get far.

I cannot for the life of me get F# to run in Visual Studio Code. I've had it up and running previously, but not with the most recent versions of the software.
I installed the most recent versions of .NET and VS code a month ago and again now, did full deletes and re-installs both times (including deleting user/.vscode and roaming/Code manually), but the error persists.
I am on a Windows 10 and have installed x64 versions of .NET Core 3.1 and VS Code 1.48 with the only extensions C# 1.23 and Ionide-fsharp 4.16. I have enabled Use Sdk Scripts for ionide, but otherwise run on default configuration. dotnet fsi is executed without problems in the command line.
Looking at the VSC extension host log:

which I believe is caused by this problem seen in the VSC F# log:
[Error - 11.24.35] Starting client failed
Launching server using command Invalid macro definition. failed.
I'm stuck here as I don't know what macro definition this refers to or how to get more information about the failure.
I just found the cause and solution for the problem. It had nothing to do with Ionide or Visual Studio Code. Instead my cmd was acting up due to misconfiguration.
For a while the message "Invalid macro definition" has been output as the first thing when I open cmd, but I didn't see the connection to the problem above. Turns out that VS code did not like this output and that it was the AutoRun configuration for cmd that triggered this error.
Using regedit, I found that I had several AutoRun files that were no good, so I removed them from respectively Computer\HKEY_CURRENT_USER\Software\Microsoft\Command Processor and Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor and the problem was solved.
I'm new to C++ and Allegro 5 but have been able to follow tutorials online and am able to build and compile several smaller projects successfully.
I cannot however get the demo project named Cosmic Protector to run and would like to at least learn what is wrong.
Unfortunately, I can't give you much to go on.
A window opens briefly and then closes, leaving the console open with the message..
process 6400 exited with code 255
If you have this demo running in VC 2017 with the latest release of Allegro 5 (5.2.4) installed via Nuget, I'd like to know that even.
The source for this program is available at...
https://github.com/liballeg/allegro5/tree/master/demos/cosmic_protector
Thank you, Jack
The allegro example programs and demos are usually built with CMake alongside the Allegro library. I just tested the CMake build of Allegro 5 with VS2017 on Windows 10 and it builds the Cosmic Protector demo successfully. You have to move the allegro dlls into the same directory as the exe, but other than that it runs perfectly.
As to why it's not working for you, cosmic protector depends on a data directory that holds it's resources. The working directory may be wrong, which would cause it to be unable to find resources. The data dir needs to be copied alongside the executable.
You can set the working directory to $(OutDir) under Debugging in Project->Properties and then it should find any data in the same directory as the exe.
How are you building cosmic protector?
Thanks to BugSquasher, I now have this working.
Here's how...
Start Visual Studio 2017
Create New Project of type Windows Console Application.
Name project CosmicProtector and save it in appropriate place on my HDD.
Disable precompiled headers and delete the any .h and .cpp
files associated with the new project regarding precompiled headers.
(for example pch.h)
Install Allegro 5.2.4 via Nuget.
In Visual Studio, navigate to Project Settings/Properties and ensure all
Allegro addons are enabled.
Copy the Cosmic Protector SRC and Header files and paste them into my
project directory.
Next in Visual Studio Project, Add the Source and Header files
respectively.
Rather stupidly, the step I had missed and that your reply brought my attention to was...
Copy the data directory and paste this into my project directory in the
applicable location.
Now build...
The project built right away, except for some errors reported in Game.cpp, GUI.cpp and Render.cpp
One error in Game.cpp, this being an instance of...
error C4996 'snprintf': This function or variable may be unsafe. Consider using snprintf_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS.
To address this I have changed the instance of snprintf to sprintf_s.
Three errors in GUI.cpp, were instances of...
Error C4996 'strcpy': This function or variable may be unsafe. Consider using strcpy_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS.
To address all of these I changed each instance of strcpy to strcpy_s.
And one error in GUI.cpp, this being an instance of...
error C4996 'snprintf': This function or variable may be unsafe. Consider using snprintf_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS.
To address this I have changed the instance of snprintf to sprintf_s.
One error in Render.cpp, this being an instance of...
error C4996 'sprintf': This function or variable may be unsafe. Consider using sprintf_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS.
To address this I have changed the instance of sprintf to sprintf_s.
Then build and it works:)
Thank you so much for your reply as I had moved on to other things but will find it very useful I think being able to build and run this demo.
It's only your reply that has brought me back to it and this time, I am successful:)
I'm struggling with building NLua from source on Windows.
It requires a modified Lua version, otherwise my code fails with a missing "lua52.dll".
https://github.com/NLua/NLua/issues/53
I tried to get it from here
https://github.com/NLua/lua
then used "cmake ." and built the resulting "lua.sln" in visual studio.
What happens is that I get a "lua52d.dll" (note the "d"). If I rename it, a "System.BadImageFormatException" is thrown by "KeraLua" (when I try with some "NLua.exe" executable I found in the "tests" folder of NLua).
Can anybody tell me how to build the modified lua52.dll required by NLua?
I already have a binary that works but need to be able to rebuild everything by myself. Possibly I'm simply using the wrong source tree.
You're using the right source tree, its just that you're compiling the debug version of the dll, not the release version of the dll. The added 'd' is to denote that it is the debug version of the dll, not the release version.
I'm to use nunit-console to run all of the tests in my solution.
I did this:
c:\some\path>nunit-console-x86.exe MySolution.sln

---------------------------
OK
---------------------------
The exception can be found here
What is happening and how do I fix it? (without having to maintain a MySolution.nunit file)
More information
MyNamespace.Administration is not even one of the dlls that contains tests, which means that nunit fails trying to load it to look for tests to run. Knowing this I edited the file created by nunit-x86.exe (MySolution.nunit) and removed all dlls that did not have tests. Sure enough, the tests work (in both gui and console). This is not acceptable for me because it would mean that I have to keep yet another configuration file. Nunit supporting .sln files was supposed to avoid this.
My tests run fine using TestDriven.Net (but I really need to run them using nunit-console)
I have looked at this answer but I cannot make sense of what the fusion log viewer says. Would posting that log help? Assembly binding Log Viewer, lists 3 files being created:
nunit-agent-x86.exe, this one seems to be trying to find MyNamespace.Administration.dll/EXE inside the nunit directories
Tests_24398275 x2 - one looking for nunit.core in my project folders and another looking for unit.core.interfaces inside my project folders. I would pay little attention to these two since they also appear in my manually edited .nunit project).
(per andreister comment) The problem seems to be with the project/assembly itself and not the creation method. If I create a .nunit project and try to add MyNamespace.Administration to it (using 'Add Assembly...' or 'Add VS project...') it fails.
Calling nunit-console-x86 somepath/bin/Debug/MyNamespace.Administration.dll directly works.
Reposting my reply on nunit-discuss:
The NUnit feature of loading VS solutions is really fairly limited and intended to work with simple projects or as a quick way to create an NUnit project file - i.e. load the solution and save as an NUnit project, then edit the xml file that is created. Since the solution file format doesn't indicate which files are tests, NUnit attempts to load each project to check if it contains any tests. (This is the same thing that Visual Studio 2012 and later does when using the test explorer window, btw.)
As you suggest, I think the particular assembly fails to load because of having a dependency that is one level up. When loading either a VS solution file or an NUnit project file, NUnit sets the application base to the directory containing the solution or project. That's why an NUnit project file one level up works.
The designers' intent in this sort of situation is that you would create an NUnit project file. I recognize that this is somewhat inconvenient, since it gives you another configuration file to maintain. I'm open to suggestions regarding the use of globs either on the command line or within the project file. Any such changes would probably go into the next major upgrade, NUnit 3.0.
Unfortunately, even after posting on nunit-discuss group I was unable to find a proper solution for this problem.
nunit-discuss group confirmed that my tests are failing because of having a dependency that is one level up.
I did however found an acceptable work-around.
Since calling the .dlls directly didn't have the same issues.
I could do this with globs, but I'm on windows... but I have git bash installed.
Taking advantage of my somewhat rigid project structure and naming convention I managed to do this:
"C:\Program Files (x86)\Git\bin\bash.exe" -c 'nunit-console-x86.exe //framework=net-4.5 //xml:nunitresults.xml MysolutionFolder/Tests/*/bin/Debug/*.Tests.dll'
Please note that I took advantage of my naming convention. This is very important to do in order to reduce the number of arguments.
When I did nunit-console-x86 MysolutionFolder/*/*/bin/Debug/*.dll instead of MysolutionFolder/Tests/*/bin/Debug/*.Tests.dll I got an error from nunit-console-x86 saying Bad file number.
Besides, it's faster if I just provide the right files.
If you have a more recent version of bash (4.0+, I think) you can instead use the following command (note the use of **):
"C:\Program Files (x86)\Git\bin\bash.exe" -c 'nunit-console-x86.exe //framework=net-4.5 //xml:nunitresults.xml MysolutionFolder/**/bin/Debug/*.Tests.dll'
Which is shorter and more permissive on the project structure.
While building our project on the Build Server, the compilation fails with the error message:
TlbImp: error TI0000 : The input file 'C:\*.dll' is not a valid type library.
We tried to manually invoke the TlbImp command thru the VS2005 Command Prompt and the same error message appeared.
To investigate, we tried to create a clean build environment in a Virtual Machine (Vbox), then we run the build there. It went fine.
We also tried to invoke the same TlbImp command thru the VS2005 Command Prompt and it succeeded.
With that, we are assuming that there is nothing wrong with the DLL. Do you have any idea what scenario(s) can cause this problem?
EDIT:
Found the problem, see my answer. ;)
If it is working on one machine and not on the other, then most probably some dependency of this DLL is missing in your machine. Inspect the dll through DependencyWalker and you will get to know that which dependency hasn't been built properly.
After closer inspection, we found out that the environment variables on the official build server is FUBAR.
The official build server was installed with both VS2003 and VS2005. Our project is VS2005. The build script is using components from VS2003 instead of VS2005 because the VS2003 paths (Path, LIB, LIBPATH and INCLUDE) were first declared before the VS2005 paths.
A simple SET command to override the environment variables with the "correct ones" fixed the build!
Thanks!
