Compiling Binaries

Linux Target

Basic C

gcc source.c -o myprog

Windows Target

sudo apt install mingw-w64

Basic C Compilation 32-bit “Hello World” (console)

i686-w64-mingw32-gcc -O2 -Wall hello.c -o hello32.exe

64-bit “Hello World” (console)

x86_64-w64-mingw32-gcc -O2 -Wall hello.c -o hello64.exe

Basic C++ Compilation 32-bit C++ (console)

i686-w64-mingw32-g++ -O2 -std=c++17 -Wall hello.cpp -o hello32.exe

64-bit C++ (console)

x86_64-w64-mingw32-g++ -O2 -std=c++17 -Wall hello.cpp -o hello64.exe

Setting Windows Version Macros To target a minimum Windows version, define _WIN32_WINNT and WINVER:

# Example: target Windows 7 (0x0601)
x86_64-w64-mingw32-gcc -D_WIN32_WINNT=0x0601 -DWINVER=0x0601 hello.c -o hello.exe

Common _WIN32_WINNT values:

0x0501 → Windows XP
0x0600 → Windows Vista
0x0601 → Windows 7
0x0602 → Windows 8
0x0A00 → Windows 10

.NET Excutables

sudo apt install -y mono-devel mono-mkbundle

sudo apt install -y gcc-mingw-w64-x86-64
sudo apt install -y gcc-mingw-w64-i6

Compile to a portable .NET EXE (IL-only) using Mono’s C# compiler (mcs):

mcs -out:Hello.exe Hello.cs

Basic 64-bit Windows EXE

mkbundle \
  --cross mono-w64 --simple \
  --static \
  --deps \
  -o Hello_native.exe \
  Hello.exe

For 32-bit Windows (Win32)

mkbundle \
  --cross mono-w64-i686 \
  --simple \
  --static \
  --deps \
  -o Hello_native32.exe \
  Hello.exe

.csproj

wget https://packages.microsoft.com/config/ubuntu/22.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt update
sudo apt install -y dotnet-sdk-7.0

dotnet --info

Ensure there’s a YourProject.csproj in that directory (or a parent directory). Restore dependencies

dotnet restore

Build

dotnet build -c Release

By default, the output goes into bin/Release/<TargetFramework>/
If you want to target a specific runtime (e.g. Windows), use: Target runtime
```
dotnet publish -c Release -r win-x64 --self-contained false
```
