# Windows 98 SE compilation (Visual C++ 6.0)
|
|
|
|
Claro has a dedicated **32-bit x86, MSVC6** build. It keeps the runtime in the
|
|
single `src/claro.c` file. This is separate from the modern MinGW x64 download.
|
|
|
|
## Build on a configured VC6 system
|
|
|
|
1. Extract the project to a short path such as `C:\CLARO`.
|
|
2. Open the compiler environment installed with Visual C++ 6.0, or run that
|
|
installation's original `VCVARS32.BAT`. Check `cl` reports compiler 12.00.
|
|
Compiler, include and library paths remain installation-specific; the project
|
|
does not bundle Microsoft's toolchain.
|
|
3. Change to the Claro folder and run:
|
|
|
|
```bat
|
|
build98.bat
|
|
```
|
|
|
|
The output is `claro98.exe`. Try:
|
|
|
|
```bat
|
|
claro98.exe --version
|
|
claro98.exe lessons\01_hello.claro
|
|
claro98.exe test
|
|
```
|
|
|
|
`build98.bat` and `build98.rsp` use 8.3-compatible names. The batch file uses no
|
|
`SETLOCAL`, `%~dp0`, `EXIT /B`, `WHERE`, or command-chaining extensions. Compiler
|
|
options live in a response file to avoid COMMAND.COM's short command-line limit.
|
|
Both files use CRLF line endings. Modernized toolchain environment wrappers may
|
|
use CMD-only syntax; use the VC6 environment appropriate to the actual host.
|
|
|
|
## Target settings
|
|
|
|
- `/TC /W3`: compile as C with normal warnings.
|
|
- `/ML /O1`: VC6 static single-threaded CRT, optimized for size. No newer Visual
|
|
C++ runtime DLL needs to be installed for this build.
|
|
- `WINVER=0x0410`, `_WIN32_WINDOWS=0x0410`: Windows 98 header target selection.
|
|
- `/MACHINE:I386 /SUBSYSTEM:CONSOLE,4.10`: 32-bit x86 console executable with a
|
|
Windows 98-era subsystem version.
|
|
- `/STACK:16777216`: 16 MiB reserve so nested calls reach Claro's existing
|
|
recursion guard instead of overflowing the default Windows stack first.
|
|
|
|
The source selects `long` for `_findfirst` handles on pre-VC7 MSVC, matching the
|
|
VC6 CRT declaration. Modern compilers retain their pointer-sized handle type.
|
|
No `/Dintptr_t=long` workaround is used.
|
|
|
|
## Verification boundary
|
|
|
|
The build is exercised with the actual MSVC600 compiler and linker under Wine.
|
|
The source/build-policy check is `python3 tools/validate_msvc6_source.py`, also
|
|
included in full release validation and CI. It does not replace the actual VC6
|
|
compiler test.
|
|
|
|
A PE header and a successful Wine test are not proof of execution on Windows
|
|
98 SE. Native Win98 SE loader/CRT, filesystem, console, shell, encoding and device
|
|
behavior still need testing on that OS or a faithful emulator. Some static VC6
|
|
CRT imports include Wide-character API entry points and fallback paths; their
|
|
presence must not be mistaken for a modern-NT-only requirement or for proof of
|
|
Win98 correctness without a real target test.
|
|
|
|
Real HTTP requires a separately compatible curl executable. No modern TLS stack,
|
|
GUI installer, Microsoft SDK or runtime DLL bundle is supplied. Run only trusted
|
|
scripts. See [portability](PORTABILITY.md) and [runtime limits](RUNTIME_LIMITS.md).
