Cross Compile dbus-glib for ARM

Source : dbus-glib-0.82

cd dbus-glib-0.82

mkdir x86
cd x86

../configure

產生的Makefile會使用builddir這個變數但compile時卻沒有定義,因此用以下方式make

builddir=$PWD/dbus make

OK 成功

cd ..

See `config.log' for more details.

錯誤發生了

強制將abstract socket namespace定義為yes並寫入cach file

echo ac_cv_have_abstract_sockets=yes > arm.cache

再試一次
OK ,成功

不需要dbus tools for ARM,修改Makefile

#SUBDIRS = dbus tools test doc
SUBDIRS = dbus test doc

再make一次
OK,成功了

builddir=$PWD/dbus make install

Cross Compile Mozilla NSS for ARM

Source : nss-3.12.5-with-nspr-4.8.2
Path : /home/gigijoe/OMAP3530/MSN/nss-3.12.5-with-nspr-4.8.2

1.Build for X86 first

make build_coreconf

cd ../../nsprpub

./configure --with-dist-prefix='/home/gigijoe/OMAP3530/MSN/nss-3.12.5-with-nspr-4.8.2/mozilla/security/nss/../../dist/Linux2.6_x86_glibc_PTH_DBG.OBJ' --with-dist-includedir='/home/gigijoe/OMAP3530/MSN/nss-3.12.5-with-nspr-4.8.2/mozilla/security/nss/../../dist/Linux2.6_x86_glibc_PTH_DBG.OBJ/include' --cache-file=/dev/null

make

cd ../security/nss/

make build_dbm

make

2.Build for ARM

Build arm

Modify ../coreconf/arch.mk

Set

OS_TEST := arm

Modify ../coreconf/Linux.mk

CC                      = arm-none-linux-gnueabi-gcc
CCC                     = arm-none-linux-gnueabi-g++
RANLIB                  = arm-none-linux-gnueabi-ranlib

cd ../../nsprpub

CC=arm-none-linux-gnueabi-gcc AR=arm-none-linux-gnueabi-ar RANLIB=arm-none-linux-gnueabi-ranlib ./configure --target=arm-linux --with-dist-prefix='/home/gigijoe/OMAP3530/MSN/nss-3.12.5-with-nspr-4.8.2/mozilla/security/nss/../../dist/Linux2.6_arm_arm-none-linux-gnueabi-gcc_glibc_PTH_DBG.OBJ' --with-dist-includedir='/home/gigijoe/OMAP3530/MSN/nss-3.12.5-with-nspr-4.8.2/mozilla/security/nss/../../dist/Linux2.6_arm_arm-none-linux-gnueabi-gcc_glibc_PTH_DBG.OBJ/include' --cache-file=/dev/null

make

cd ../security/nss/

make build_dbm

make

Then there's error

很明顯是無法執行shlibsign,把X86 build的binary拿來取代就行

cd cmd/shlibsign/
cp Linux2.6_x86_glibc_PTH_DBG.OBJ/shlibsign Linux2.6_arm_arm-none-linux-gnueabi-gcc_glibc_PTH_DBG.OBJ/
cd ../..

繼續

shlibsign: shlibsign.c:772: main: Assertion `lib != ((void *)0)' failed.

應該也是相同的問題,換成X86 build的library

cd ../../dist/Linux2.6_arm_arm-none-linux-gnueabi-gcc_glibc_PTH_DBG.OBJ/lib
cp -a ../../Linux2.6_x86_glibc_PTH_DBG.OBJ/lib/libsoftokn* .
cd ../../../security/nss/

make

完成囉

Dynamic Link Program Tips

1.Information of program

$ file pjsua-arm-unknown-linux-gnu
pjsua-arm-unknown-linux-gnu: ELF 32-bit LSB executable, ARM, version 1 (SYSV), for GNU/Linux 2.6.14, dynamically linked (uses shared libs), not stripped

顯示program為dynamic link, 未最佳化

2.Strip

$ arm-none-linux-gnueabi-strip pjsua-arm-unknown-linux-gnu
pjsua-arm-unknown-linux-gnu: ELF 32-bit LSB executable, ARM, version 1 (SYSV), for GNU/Linux 2.6.14, dynamically linked (uses shared libs), stripped

最佳化最明顯的效果是size變小

3.Shared Libraries

$ arm-none-linux-gnueabi-readelf -a pjsua-arm-unknown-linux-gnu | grep "Shared\ library"
 0x00000001 (NEEDED)                     Shared library: [libm.so.6]
 0x00000001 (NEEDED)                     Shared library: [libnsl.so.1]
 0x00000001 (NEEDED)                     Shared library: [librt.so.1]
 0x00000001 (NEEDED)                     Shared library: [libpthread.so.0]
 0x00000001 (NEEDED)                     Shared library: [libc.so.6]

libtool: Version mismatch error

碰到一個關於libtool版本的問題,先記錄下來.

libtool: Version mismatch error.  This is libtool 2.2.6, but the
libtool: definition of this LT_INIT comes from an older release.
libtool: You should recreate aclocal.m4 with macros from libtool 2.2.6
libtool: and run autoconf again.

解決的方式是進入project 最上層目錄(也就是含有configure檔案的目錄)

autoreconf -f -l
./configure ...
