Introduction
Hi Everyone.
In 2020 there was a news at 4Chan that the source code of Windows XP and Windows Server 2003 has been leaked. The code was widely spread through the Internet, including GitHub, which belongs to Microsoft. The company started to undertake the actions for code blocking and many websites and repos were excluded from the search systems.
What is the situation in 2023? Surprisingly, the sources could be found and downloaded from GitHub without any issues. It is easy to find the instructions and videos how to compile everything with the tools, which are included with the OS code.
Windows XP is one of the most favorite OS along all of the OS from Microsoft for me. It is quite fast and lightweight. At the same time, its interface is quite comfortable for work. For this reasons and since I am the C and C++ developer, it is quite interesting for me to explore the sources of this OS.
The available version of Windows XP is about 6 GB after unboxing. If we run the cloc analyzer and wait for 10 minutes, we will see the following statistics:

The most of the code is written in C, C++ and assembly, which comprise 40.7 millions lines in total. From the references we can find that the available version of Windows XP contains about 70 % of the source code. Thus, the total amount of the OS code could be estimated as 58 millions lines.
It is obvious that it is impossible to analyze 41 millions lines of the code within the scope of the article. For this reason I decided to start from some small application. I choose the classical calculator. Why calculator? It is quite simple, I just would like to compile the calculator, which can make the calculations without connection to the Internet :).
At the same time, it is quite simple to compile it using the Microsoft compiler. For this reason, I decided to make a challenge and to compile it using GCC x64.
Setup of environment
We need to have the following environment:
Host with the installed Windows. In my case it is Windows 10.
Qt. I use both QtCreator and GCC port for Windows MinGW-64. I installed both with the Qt Maintanance Tool. After the setup completed, the compiler should be added to Path.
The
makeutility since we will useMakefile.
Compilation of calculator
If we try to analyze the amount of calculator and its dependencies code with cloc we will see the following statistics:

To build calc.exe we need to compile amount 8000 lines of code from 42 files. If we scroll the code we will see that it is quite old and it is written in 80-90th of XX century. This code is mostly C code and the files have .c extension. However, from time to time it throws exceptions and it could be compiled only with g++.
Now we can open QtCreator and import the sources of the OS. It could hang for some time since there is a huge amount of files. We need to wait 15-20 minutes.
After the import procedure has been completed, we search for the calc. The calculator sources are located at:
NT\shell\osshell\accesory\calc
If we open this folder we can see .c and .h files as well as a nt folder, where we can find the build parameters, including the list of files. Let us create a Makefile in calc folder taking the template from my previous paper about STM32 and adapt it for our case. The initial parameters we can take from nt/sources. Makefile looks like this:
Calc makefile
TARGET = calc BUILD_DIR = build OPT = -O0 CC = g++ C_SOURCES = calc.c \ input.c \ scicomm.c \ scidisp.c \ scifunc.c \ scikeys.c \ scimath.c \ scimenu.c \ scioper.c \ sciproc.c \ sciset.c \ scistat.c \ unifunc.c \ wassert.c C_DEFS = -DWIN32 \ -DW3 \ -DWINNT \ -DUNICODE \ -D_UNICODE \ -DUSE_MIRRORING C_INCLUDES = -I..\ratpak \ -I..\inc \ CFLAGS += $(C_DEFS) $(C_INCLUDES) $(OPT) LIBS = LIBDIR = LDFLAGS = $(LIBDIR) $(LIBS) all: $(BUILD_DIR)/$(TARGET) OBJECTS = $(addprefix $(BUILD_DIR)/,$(notdir $(C_SOURCES:.c=.o))) $(BUILD_DIR)/%.o: %.c Makefile | $(BUILD_DIR) $(CC) -c $(CFLAGS) -o $@ $< $(BUILD_DIR)/$(TARGET): $(OBJECTS) Makefile $(CC) $(OBJECTS) $(LDFLAGS) -o $@ $(BUILD_DIR): mkdir $@ clean: -rm -fR $(BUILD_DIR)
Let us try to build the project with make.

We can see a long output. The part of warnings tells us about the redefinition of macros in the headers from modern version of Windows. At the end we can see the error connected with the ratpak library. Using the config file from nt/source we can find that ratpak sources are located one level above.
NT\shell\osshell\accesory\ratpak
Let us try to build it. To do it, we create a new Makefile with the following content taking the config from the analogous nt/source:
Ratpak makefile
TARGET = ratpak.lib BUILD_DIR = build OPT = -Os C_SOURCES = rat.c \ num.c \ conv.c \ debug.c \ itrans.c \ trans.c \ transh.c \ itransh.c \ logic.c \ fact.c \ basex.c \ exp.c \ support.c \ CC = g++ C_DEFS = -DWIN32 \ -DW3 \ -DWINNT \ -DUNICODE \ -D_UNICODE \ -DNOMINMAX C_INCLUDES = -I. CFLAGS += $(C_DEFS) $(C_INCLUDES) $(OPT) all: $(BUILD_DIR)/$(TARGET) OBJECTS = $(addprefix $(BUILD_DIR)/,$(notdir $(C_SOURCES:.c=.o))) vpath %.c $(sort $(dir $(C_SOURCES))) $(BUILD_DIR)/%.o: %.c Makefile | $(BUILD_DIR) $(CC) -c $(CFLAGS) -o $@ $< $(BUILD_DIR)/$(TARGET): $(OBJECTS) ar ru $@ $^ ranlib $@ $(BUILD_DIR): mkdir $@ clean: -rm -fR $(BUILD_DIR)
The primary difference here is that we build ratpak as a static library and for this reason it should be build with the following config:
$(BUILD_DIR)/$(TARGET): $(OBJECTS) ar ru $@ $^ ranlib $@
Let us try to build with make:
Ratpak build output - 1

We can see the error, which is attributed with min and max macro. Let us add this functions from STL. To do this, we create custom.h file and add the following context.
#pragma once #include <algorithm> using std::min; using std::max;
Next, we include this header to num.c, logic.c and support.c and rebuild:

We can see the 2 types of errors. In the first case, we can see the missing type in support.c in lines 41 and 64. We need to add int there:
static int cbitsofprecision
In the second case we try to initialize the 0-sized array in NUMBER structure from ratpack.h with a few elements. Let us remove 0 from [0], leaving the empty brackets. Now we can rebuild the library and make sure that there are no errors. Our library ratpack.lib is located in build.

We can see that there are a few unlinked functions:HtmlHelpW function is located in libhtmlhelp, __imp_SetBkMode, etc. are the functions from gdi32 library. The other functions are from ratpack. For the first 2 cases we can add the linkage to Makefile
LIBS = -lratpak -lgdi32 –lhtmlhelp
The htmlhelp library is a part of Windows SDK. Since GCC does not support the spaces in the path, we need just copy this library to lib folder and add the path to it.
LIBDIR = -L..\ratpak\build -Llib
In the third case the problem is with the inline modifier in mulnum, divnum functions from num.c and mulnumx, divnumx in basex.c. It is necessary to remove the modifier for GCC.
Let us try to build:

We can see that we need a library with __security_check_cookie and __GSHandler_Check. It is connected with /GS flag of Visual Studio compiler since initially I took htmlhelp from Windows SDK 8.0. /GS flag is analog of -fstack-protector-strong for GCC. To link __security_check_cookie correctly we need to add -lbufferoverflowu (from SDK). For __GSHandler_Check we should link -lruntmchk, which I failed to find. Another opportunity is the linkage with gshandler.obj.
However, htmlhelp is compiled in a static library in SDK, and I decided to build it from the sources of Windows XP.
I found the following directory:
NT\enduser\stuff\hhctrl\
It contains a lot of files and htmlhelp.h header. If we go one level above, we can see htmlhelp folder.
NT\enduser\stuff\htmlhelp\
If we look inside, we can see only one file init.cpp . I decided to build it using the adapted Makefile from ratpak . Surprisingly, it has been built without any issues!
Htmlhelp build output - 1
mkdir build g++ -c -I..\hhctrl -Os -o build/init.o init.cpp ar ru build/htmlhelp.lib build/init.o ar: creating build/htmlhelp.lib ranlib build/htmlhelp.lib
If we add the path to this library in Makefile, we can see that everything is successfully built and linked.

Finally, we have the build of our calculator. Let us make some cleanup fixes to remove the warnings by deletion of #define ARRAYSIZE(x) (sizeof(x) / sizeof(*x)) from unifunc.h and enable Os optimization. In this case we can get the following image:
OPT = -Os

To fix it, I added -fno-aggressive-loop-optimizations flag. At the end we have the clean compilation output:

Launching of the compiled calculator
If we try to launch the built calculator app, we will see the following image:
That means it is necessary to provide the linkage of the graphical application instead of console application to the linker. For GCC it is -mwindows.
LDFLAGS = $(LIBDIR) $(LIBS) -fno-aggressive-loop-optimizations -mwindows
If we rebuilt and launch the application, we will not see any windows, but the process exists in the list of processes:
Thus, our application has been launched, but there is missing description of the graphical interface. For OS Windows this information is located in resource files with .rc extension. To attach calc.rc file we need to compile it to object file calc.rc.o and then to link with the calc binary. MinGW-64 has the windres resource compiler, that we can use.
Let us try to compile calc.rc in object file with a command:
windres calc.rc -o build/calc.rc.o
We will see the following error:
calc.rc:12:10: fatal error: winres.h: No such file or directory #include "winres.h" ^~~~~~~~~~ compilation terminated. windres: preprocessing failed.
To fix it we can try to replace winres.h to windows.h and recompile again. In this case there is no output and the build folder contains the required object file calc.rc.o.
Let us add to the calc Makefile the following code for .rc.o linkage:
RC = windres RES_SOURCES = calc.rc RES_OBJ = $(addprefix $(BUILD_DIR)/,$(notdir $(RES_SOURCES:.rc=.rc.o))) $(BUILD_DIR)/%.o: %.rc Makefile | $(BUILD_DIR) $(RC) $^ -o $@ $(BUILD_DIR)/$(TARGET): $(OBJECTS) Makefile $(CC) $(OBJECTS) $(RES_OBJ) $(LDFLAGS) -o $@
I tried to add the build of .rc file to Makefile, but the compilation of this file failed using Makefile. If someone knows how to fix it I will be glad to read about it in the comments.
Finally everything was linked correctly and the build folder contains the calc.exe binary. If we launch it we will see our old application:
Finally, we can add the -Wall flag to see all warnings and recompile:

Here we see a lot of warnings:
unknown-pragmas (#pragma warning)
sign-compare
parentheses
unused-variable
maybe-uninitialized
dangling-else
unused-but-set-variable
Currently, the most of the warnings would be detected by both compilers as well as by static analyzers.
At the end I would like to provide the final code of Makefiles.

Conclusions
Finally we have the compiled version of calculator from WindowsXP with GCC x64, which launches on the modern versions of Windows. In contrast to the modern version of calculator, which consumes 18.7 MB of memory, the old one consumes only 1.0 MB.
The assembled application works perfectly except of help menu, which does not appear. Probably it is connected with hhctrl library. If you have any ideas what to build next time, please write them in the comments.
I hope the article was interesting and useful. Thank you for attention!
