|

## 2. Instalación rápida — Docker / Linux
|

**La emulación ESP32 completa está incluida en la imagen Docker oficial.** No requiere ninguna instalación adicional — la `libqemu-xtensa.so` se compila automáticamente durante el build de la imagen a partir del fork lcgamboa.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 2.1 Usar la imagen precompilada (recomendado)
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
|
|
docker run -d \
|
|
|
|
|
|
|
|
--name velxio \
|
|
|
|
|
|
|
|
-p 3080:80 \
|
|
|
|
|
|
|
|
-v $(pwd)/data:/app/data \
|
|
|
|
|
|
|
|
-e SECRET_KEY=tu-secreto \
|
|
|
|
|
|
|
|
ghcr.io/davidmonterocrespo24/velxio:master
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
La emulación ESP32 con GPIO completo está activa automáticamente. No se necesita ninguna variable de entorno adicional.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 2.2 Build local de la imagen
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
|
|
git clone https://github.com/davidmonterocrespo24/velxio.git
|
|
|
|
|
|
|
|
cd velxio
|
|
|
|
|
|
|
|
docker build -f Dockerfile.standalone -t velxio .
|
|
|
|
|
|
|
|
docker run -d -p 3080:80 -e SECRET_KEY=secreto velxio
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
> **Nota de build time:** La compilación de QEMU tarda 15-30 minutos la primera vez.
|
|
|
|
|
|
|
|
> Los builds posteriores usan la capa Docker cacheada — son instantáneos mientras no
|
|
|
|
|
|
|
|
> cambie el source de lcgamboa.

### 2.3 Verificar emulación ESP32 en el container
|

### 9.2 Detalle del relink como DLL
|
|
|
|
El script configura QEMU con `--extra-cflags=-fPIC` (necesario para Windows/PE con ASLR), compila el binario completo y luego relinks eliminando `softmmu_main.c.obj` (que contiene `main()`):
|
|
|
|
|
|
|
|
|
|
|
|
El proceso extrae el comando de link de `build.ninja`, elimina `softmmu_main.c.obj` (que contiene `main()`), y agrega flags de DLL:
