Actualmente trato de construir un Linux incorporado desde cero con las instrucciones de Cross Linux desde cero .
Todo funcionó bien hasta que intenté compilar el compilador cruzado de GCC. Quiero construir el Linux para Beagleboard-xM ... Así que elegí la siguiente configuración:
export CLFS_ABI="aapcs-linux"
export CLFS_HOST="x86_64-cross-linux-gnu"
export CLFS_TARGET="armv7a-unknown-linux-uclibceabi"
export CLFS_ARCH="arm"
export CLFS_ENDIAN="little"
export CLFS_ARM_ARCH="armv7"
export CLFS_ARM_MODE="arm"
export CLFS_FLOAT="hard"
export CLFS_FPU="neon"
No, tan pronto como intento ejecutar las instrucciones en esta página, el comando se make all-gcc all-target-libgcc
encuentra con un error.

intenta encontrar la versión xgcc con-V
pero en mi ubuntu solo-v
funciona ...Respuestas:
Es probable que los errores provengan de una combinación incorrecta de variables de compilación.
La página CLFS Build Variable tiene una explicación detallada sobre las mejores combinaciones de configuraciones variables para diferentes arquitecturas.
Problemas de script de configuración similares se han resuelto cambiando la
CLFS_ARCH
variable athumb
Para otro error similar del script de configuración de BeagleBoard, el siguiente conjunto de variables parece funcionar:
ARMv7-A Thumb-2 - Little-Endian, Soft-Float, GLIBC
Si ha estado usando CLFS 1.xx, considere usar CLFS 2.xx para un enfoque de compilación más limpio, con documentación actualizada .
El mejor lugar para discutir problemas de CLFS es en la lista de correo de soporte de clfs , intente hacer su pregunta allí para obtener más información.
