parametros ejecutar compilar compilador arm cross-compiling libtool expat-parser

arm - ejecutar - Libtool afirma que no admite bibliotecas compartidas durante la compilación cruzada



gcc linux (2)

Si está utilizando Homebrew como su administrador de paquetes, tenga en cuenta que algunas fórmulas se vierten de botellas compiladas a 32 bits como el mínimo común denominador. Puede reconstruir libtool a su arquitectura nativa mediante el uso de

$ brew install --build-from-source libtool`

o simplemente pasando cualquier bandera válida

$ brew install --universal libtool

La mayoría de las fórmulas tienen la bandera --universal que generará las arquitecturas i386 y x86_64.

Estoy intentando construir la biblioteca de análisis XML expat (2.0.0) para una máquina embebida ARM ejecutando busybox 1.13, y durante el archivo ./configure, obtengo el error:

checking if libtool supports shared libraries... no

Especifiqué mi gcc, g ++, ar, ranlib, strip, etc. y todos fueron encontrados por la herramienta de configuración, y tengo el último libtool (2.4.2 en el momento de escribir esto) ejecutándose en Ubuntu 12.10 , entonces, ¿por qué está diciendo que libtool no admite bibliotecas compartidas? Mi comando de configuración es:

./configure --host=arm --enable-shared CC=arm-none-linux-gnueabi-gcc CXX=arm-none-linux-gnueabi-g++ AR=arm-none-linux-gnueabi-ar RANLIB=arm-none-linux-gnueabi-ranlib STRIP=arm-none-linux-gnueabi-strip

... y la salida completa de la llamada es:

¿Podría alguien explicarme cómo la configure determina si libtool admite la creación de bibliotecas compartidas?

De la salida:

Probablemente, libtool se confunde con su bandera de host: --host=arm , que para libtool es lo mismo que --host=arm-unknown-none . Pruebe --host=arm-none-linux lugar. IIRC, arm-unknown-none es utilizado por personas que quieren hacer cosas que no sean RTOS (bucle principal) para MCU y otras placas integradas donde no hay sistema operativo y todo está vinculado estáticamente a una imagen. Su cadena de herramientas está diseñada para Linux: arm-none-linux .
