I have installed MinGW on my windows7 machine, using instructions from here. Basically I used the GUI installer assistant called mingw-get-setup.exe. The installation manager allowed me to select a package called mingw32-libpthreadgc which installs bin/pthreadGC2.dll and bin/pthreadGCE2.dll.
To my knowledge that is not sufficient to compile code depending on the pthread library. E.g. trying to compile a file with a header-include like #include "pthread.h" - to no surprise - results in a "file not found" compile error. I can't find that header in my MinGW directory. If I use includes/headers from elsewhere, I'm afraid they might not match with the DLL's interface. How is this meant to be working?
(Furthermore I like to use CodeBlocks as the IDE. How would I set up a simple "HelloWorld"-like pthread program to get it all to work? There seems to be a lot of conflicting messages out there on how to set it up. Use "-pthread" vs "-lpthread". Set it in compiler and linker settings, right? Copy-paste the DLL's? What else???)
I had similar problem, https://www.sourceware.org/pthreads-win32/ this did job for me,
I used this in combination with mingw32. It also has nice README file.

How to compile srlua?
How do I Make an executable Lua script using srlua?
The first link is the exact question I am asking here. However, the sole answer is unsatisfactory as it assumes multiple things, namely that the OP is already using Cmake (a fact disproved by the OP's comment on the answer). The second link seems to already be most of the way through a tutorial, and while a link to precompiled binaries for both srlua.exe and srglue.exe are provided, the link no longer contains binaries but instead the source.
I have found several other threads on various websites all asking the same thing, but all of them either assume that you essentially already know how, or explain nothing (many have potentially helpful links, but they are old and no longer work).
I have already tried to compile srlua, and got a srglue.exe, but when I tried srlua.c I ended up with a list of undefined references (such as "lua_type" or "lua_getfield").
lua_getfield, lua_type, lua_settop, lua_getfield, lua_type, lua_settop, lua_pushstring, lua_pushinteger, lua_call, lua_pushfstring, lua_load, lua_tolstring, lua_tointeger, lua_touserdata, luaL_openlibs, lua_createtable, lua_pushstring, lua_rawseti, lua_setfield, luaL_checkstack, lua_pushstring, lua_call, lua_tolstring, luaL_callmeta, lua_type, lua_type, lua_typename, lua_pushfstring, luaL_newstate, lua_pushcclosure, lua_pushcclosure, lua_pushinteger, lua_pushlightuserdata, lua_pcall, lua_tolstring, lua_close
My question is this:
How does one use a C compiler (I know the basics of gcc) to compile srlua specifically? Or, if anyone has a functioning link to either precompiled binaries or a tool to compile the binaries, could they share it?
Important: I am on Windows. Thus, I cannot just use make. I must actually compile the .c files to .exe files. I am asking how. If you simply provide links to threads with the aforementioned problems, you are not helping. If you give an answer that assumes in-depth prior knowledge of a particular tool that does not have good documentation, you are not being helpful. If you tell me tools to use, but not the specific procedure for compiling srlua, you are not being helpful. If there is a better place for this, tell me and I can move it there.
I don't know any Windows pre-compiled binaries for srLua.
To compile srLua, you should first install the Mingw compiler to use GCC as a C compiler : you can install TDM-GCC (https://jmeubank.github.io/tdm-gcc) or http://winlibs.com.
You can then open a Console prompt. Enter the "gcc" command to be sure that the compiler is working (and that the PATH is correctly set).
Then go to the directory you extracted the srLua source files and type the command :
mingw32-make
Cross your fingers and it should compile everything :)
When linking, you should include the Lua libraries with the -l Switch : -llua54 for Lua 5.4 library for examples.
I found this already compiled release on webarchive, it's kinda old but works:

I am using Code::Blocks with wxwidgets and I have include and lib folders under Document\wxwidgets. I am very new to c++ libraries. In Code::Blocks project initialization, I entered the location for wxwidgets. Then in setting/global enviornment variables I entered in base the Document\wxwidgets again. Still, I am not able to run the app. It shows the error in the include/wx/platform.h file where it says
C:\Users\Programming coder\Documents\wxwidgets\include\wx\platform.h|148|fatal error: wx/setup.h: No such file or directory|
I am not able to solve this and would appreciate some help. Also I checked and the wx folder does not seem to be there in the location. I don't know if that is normal.
Also, I downloaded the headers(include) from the wxwidgets github repo download page, wxWidgets-3.1.1-headers.7z. Any help appreciated.
Also, I am aware some questions exist already, but their problems are in different because most are using linux. Also I am using Code::Blocks IDE.
You need to build wxWidgets itself before building the applications using it. Its build process will create the setup.h file which is currently missing.
Note that, in principle, you could also use precompiled binaries, but in this case you must use exactly the same compiler as was used for compiling them, i.e. TDM gcc.
I'd like to use open source library on Windows. (ex:Aquila, following http://aquila-dsp.org/articles/iteration-over-wave-file-data-revisited/) But I can't understand anything about "Build System"... Everyone just say like, "Unzip the tar, do configure, make, make file" at Linux, but I want to use them for Windows. There are some several questions.
i) Why do I have to "Install" for just source code? Why can't I use these header files by copying them to the working directory and throw #include ".\aquila\global.h" ??
ii) What are Configuration and Make/Make Install? I can't understand them. I just know that configuration open source with Windows need "CMake", and it is configuration tool... But what it actually does??
iii) Though I've done : cmake, mingw32-make, mingw32-make install... My compiler said "undefined references to ...". What this means and what should I do with them?
You don't need to install for sources. You do need to install for the libraries that get built from that source code and that your code is going to use.
configure is the standard name for the script that does build configuration for the software about to be built. The usual way it is run (and how you will see it mentioned) is ./configure.
make is a build management tool (as the tag here on SO will tell you). One of the most common mechanisms for building code on linux (etc.) is to use the autotools suite which uses the aforementioned configure script to generate build configuration information for use by generated makefiles which make then uses to build the software. make is also the way to run the default build target defined in a makefile (which is often the all target and which usually builds the appropriate library/binary/etc.).
make install is a specific, secondary, invocation of the make tool on the install target which (generally) installs the (in this case previously) built code into an appropriate location (in the autotools/configure universe the default location is generally under /usr/local).
cmake is, again as the SO tag says, a build system that generates configuration files for other build tools (make, VS, etc.). This allows the developers to create the build configuration once and build on multiple platforms/etc. (at least in theory).
If running cmake worked correctly then it should have generated the correct information for whatever target system you told it to use (make or VS or whatever). Assuming that was make that should have allowed mingw32-make to build the software correctly (assuming additionally that mingw32-make is not a distinct cmake target than make). If that is not working correctly then something is still missing from your system (and cmake probably should have caught that).
But to give any more detail you will need to give more detail about what errors you are actually getting and from what command.
(Oh, and on Windows, and especially if you plan on building your software with VS (or some other non-mingw32-make tool) the chances of you needing to run mingw32-make install are incredibly small).
For Windows use cmake or latest ninja.
The process is not simple or straight, but achievable. You need to write CMake configuration.
Building process is not simple and straight, that's why there exists language like Java(that's another thing though)
Rely on CMake build the library, and you will get the Open-Source library for Windows.
You can distribute this as library for Windows systems, distribute and integrate with your own software, include the Open Source library, in either cases, you would have to build it for Windows.
Writing CMake helps, it would be helpful to build for other platforms as well.
Now Question comes: Is there any other way except CMake for Windows Build
Would you love the flavor of writing directly Assembly?
If obviously answer is no, you would have to write CMake and generate sln for MSVC and other compilers.
Just fix some of the errors comes, read the FAQ, Documentation before building an Open Source library. And fix the errors as they lurk through.
It is like handling burning iron, but it pays if you're working on something meaningful. Most of the server libraries are Open Source(e.g. age old Apache httpd). So, think before what you're doing.
There are also not many useful Open Source libraries which you could use in your project, but it's the way to Use the Open Source libraries.
There was a similar question (here or on some related SE site), but I didn't find so I ask a new question (if you find it, send a link and vote to close this question if they are too similar).
I have finished installing WxWidgets (configure; make; make install), but while installing PgAdmin III 1.16 the make console doesn't recognize WxWidgets as installed. I found that absence of Unicode might be a problem in this case, but I have enabled the Unicode. What else should I do?
I have 32bit Windows XP and WxWidgets 2.9.4. Including PostgreSQL 9.1.3 went OK.
EDIT: I tried another way - through Visual Studio and Visual C++. I don't know if my problem is the same or just similar, but Visual Studio reports this error:
error C1083: Cannot open include file: 'wx/wxprec.h': No such file or directory
followed by 100 of other errors which seem to be conclusion of this one (mostly undefined types/functions with names beginning with "wx"). I added semicolons to the header (as was suggested here - fourth entry after "all replies"), but it didn't help. I also tried to add "include" and "lib" directories in WxWidgets to include path for every project, but no joy here.
Do anybody know how to solve it?
You need to point pgAdmin to wxWidgets installation under Windows. Its build instruction should explain how to do it but you must set up the include path (-I compiler option) and the libraries path (-L linker option) for it to compile and link properly.
Notice that for the include paths you must put the directory containing the wx/setup.h file generated during the build by configure first and the directory with all the rest of wx headers later.
Also, it probably goes without saying, but you must use the same compiler to build both wxWidgets and pgAdmin, so if you built wx using configure+make you can't use MSVC for pgAdmin.
For my bachelors thesis, I am implementing a distributed version of an algorithm for factoring large integers (finding the prime factorisation). This has applications in e.g. security of the RSA cryptosystem.
My vision is, that clients (linux or windows) will download an application and compute some numbers (these are independant, thus suited for parallelization). The numbers (not found very often), will be sent to a master server, to collect these numbers. Once enough numbers have been collected by the master server, it will do the rest of the computation, which cannot be easily parallelized.
Anyhow, to the technicalities. I was thinking to use Boost::Asio to do a socket client/server implementation, for the clients communication with the master server. Since I want to compile for both linux and windows, I thought windows would be as good a place to start as any. So I downloaded the Boost library and compiled it, as it said on the Boost Getting Started page:
bootstrap
.\bjam
It all compiled just fine. Then I try to compile one of the tutorial examples, client.cpp, from Asio, found (here.. edit: cant post link because of restrictions). I am using the Visual C++ compiler from Microsoft Visual Studio 2008, like this:
cl /EHsc /I D:\Downloads\boost_1_42_0 client.cpp
But I get this error:
/out:client.exe
client.obj
LINK : fatal error LNK1104: cannot open file 'libboost_system-vc90-mt-s-1_42.lib'
Anyone have any idea what could be wrong, or how I could move forward? I have been trying pretty much all week, to get a simple client/server socket program for c++ working, but with no luck. Serious frustration kicking in.
Thank you in advance.
The reason the build is failing is because it cannot find the library file containing boost system. Boost includes a "handy" autolinking feature, such that when you include a header file for a binary libaray (as opposed to a header only library), boost automatically tells the compiler that it should link in the library. The downside to this is that boost doesn't tell the compiler where to find the library.
The short answer is to read a little further in the boost getting started guide. This page shows you how to add the necessary flags to the compiler command line: Getting started on windows: linking from the command line.
The first thing you have to do is find the .lib file. Boost hides them in a deep directory structure, so search for it starting in the directory you ran bjam from. Make note of the directory where the file is. You may also wish to use bootstrap --prefix=/some/install/location and bjam install to install boost somewhere other than the source directory in which you built it.
Are you building your project using a Visual Studio solution, or on the command line?
If you are using a solution file, find the link page in the solution properties. There should be a box where you can enter additional library paths. Add the directory in which you boost .lib files reside to this box.
If you are using cl on the command link, familiarize yourself with the command line options for cl and link. You can pass commands to the linker using the cl option /link, and the linker command you are looking for is /libpath.
