Download the executable from
Releases, or compile it from the
source code, and run it. Since the executable is unsigned, the popup
Windows protected your PC will appear at first launch.
MSYS2, MinGW, build-essentials, g++, and gdb.
Here is a guide on getting this
setup.
Dependencies pdh.lib, wbemuuid.lib, ole32.lib, and oleaut32.lib are already in
the Windows 11 environment. No vcpkg environment
is needed.
Optional: If you want to add an icon, save it as .ico in the project. Since I use
MinGW, I need to compile it to .res using windres first. Then, add the cmon.res
input file to the build command.
windres res/cmon.rc -O coff -o res/cmon.resBuild using the following command. Omit the res/cmon.res if you skip icon.
x86_64-w64-mingw32-g++ -static -static-libgcc -static-libstdc++ -Ofast -o build/cmon.exe src/Main.cpp res/cmon.res -lpdh -lole32 -loleaut32 -lwbemuuidLinks
- The library
pdh.libis linked, which contains the Performance Data Helper (PDH) API functions. wbemuuid.lib,ole32.lib,oleaut32.libare linked to include the WMI library, the COM library, and the OLE Automation library, which are used for querying the system for the processor's model name.- The DLL's
libgccandlibstdc++are needed, they are linked statically. - Also, link other required static DLL's using
-static.
If you want the program to ask for admin privileges automatically when running, which is
useful for automatic terminal window resizing, you can embed a "manifest" asking for
this by using the mt tool in the Windows SDK. Make sure to add its path to the user's
Path environment variable:
C:\Program Files (x86)\Windows Kits\10\bin\<version>\x64\mt.exe. Then you can run the
following.
mt.exe -manifest res/cmon.manifest -outputresource:build\cmon.exe;1Check your user's PATH environment variable.
reg query "HKCU\Environment" /v PathRun the program directly from the build folder in separate cmd instance.
start build\cmonCopy the program to a folder that I have on my user's PATH.
copy /Y build\cmon.exe C:\Users\carl\binTo empty the build folder, run the following command. May be useful for debugging or saving disk space.
del build\*.exeCheck size of files in the build folder.
dir build /o:-s
