[Golem] Compilazione libreria Python - pycups

[Adm]

SOLUZIONE:
Passi suggeriti:
1) installare uno storage USB come filesystem principale
http://wiki.openwrt.org/doc/howto/usb.storage
2) installare i pacchetti per la stampa e cups come consigliato da
Francisco Borges
https://github.com/FranciscoBorges/openwrt-printing-packages . Non è un
pacchetto ufficiale, ma è citato qui:
http://wiki.openwrt.org/doc/howto/cups.server
3) installare python sul router

Passi successivi:
3) scaricare sul PC l'ambiente di compilazione openwrt con mips. Seguire
questa guida
http://wiki.openwrt.org/doc/howto/buildroot.exigence
4) copiare le cartelle /usr/lib e /usr/include dal router alla propria
cartella di staging sul PC, all'interno dell'ambiente di compilazione
5) Sul computer, sostituire temporaneamente il file
/usr/include/python2.7/pyconfig.h con quello resente all'interno del router
6) scaricare il pacchetto pycups in una cartella sul PC
https://pypi.python.org/pypi/pycups
7) entrare nella cartella di pycups e lanciare make come indicato nella
procedura di cross compiling
8) la procedura si bloccherà per un errore nella fase di link dei file ".o"
(objects).

Errore "collect2: error: ld returned 1 exit status
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
make: *** [cups.so] Error 1"

Comando che ha generato l'errore:
"x86_64-linux-gnu-gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions
-Wl,-z,relro -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall
-Wstrict-prototypes -D_FORTIFY_SOURCE=2 -g -fstack-protector
--param=ssp-buffer-size=4 -Wformat -Werror=format-security
/home/linuxlover/openwrt/trunk/staging_dir/toolchain-mips_34kc_gcc-4.6-linaro_uClibc-0.9.33.2/usr/lib
/home/linuxlover/openwrt/trunk/staging_dir/toolchain-mips_34kc_gcc-4.6-linaro_uClibc-0.9.33.2/usr/include
build/temp.linux-x86_64-2.7/cupsmodule.o
build/temp.linux-x86_64-2.7/cupsconnection.o
build/temp.linux-x86_64-2.7/cupsppd.o build/temp.linux-x86_64-2.7/cupsipp.o
-lcups -o build/lib.linux-x86_64-2.7/cups.so
"

9) sostituire "x86_64-linux-gnu-gcc" (o simile) con
"mips-openwrt-linux-gcc" e rimuovere "-fstack-protector". Rimuovere anche i
percorsi relativi alle cartelle include e lib presenti nella staging_dir

10) lanciare "
mips-openwrt-linux-gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions
-Wl,-z,relro -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall
-Wstrict-prototypes -D_FORTIFY_SOURCE=2 -g --param=ssp-buffer-size=4
-Wformat -Werror=format-security  build/temp.linux-x86_64-2.7/cupsmodule.o
build/temp.linux-x86_64-2.7/cupsconnection.o
build/temp.linux-x86_64-2.7/cupsppd.o build/temp.linux-x86_64-2.7/cupsipp.o
-lcups -o build/lib.linux-x86_64-2.7/cups.so
"

11)  copiare la cartella pycup sul router
12)  sul router rinominare lib.linux-x86_64-2.7 e temp.linux-x86_64-2.7
con lib.linux-mips-2.7 e lib.linux-mips-2.7
13) sul router, lanciare python setup.py install
