Hi experts,

#My question: I met problem when to cross compile alsa-lib and alsa-utils.Could you please help on it? Thanks in advance.

#details My host PC: ubuntu 11.10 64-bit; Alsa-lib source code version: 1.0.23; Alsa-utils source code version: 1.0.23; My target platform: PandaBoard; My build shell script: #!/bin/bash echo "=======================start build alsa-lib-1.0.23==============" cd ./alsa-lib-1.0.23/ export CC=arm-linux-gnueabi-gcc echo "-------------->`pwd`" ./configure --target=arm-linux --host=i686-linux --prefix=/home/tim/work/dev_board/tools/ALSA/output/alsa_lib --disable-python make clean make make install cd - echo "========================end build alsa-lib-1.0.23==============="

echo "=======================start build alsa-utils-1.0.23====================" cd ./alsa-utils-1.0.23/ echo "-------------->`pwd`" ./configure --target=arm-linux --host=i686-linux --with-alsa-inc-prefix=/home/tim/work/dev_board/tools/ALSA/output/alsa_lib/include --with-alsa-prefix=/home/tim/work/dev_board/tools/ALSA/output/alsa_lib/lib --disable-alsamixer --disable-xmlto make

I can build Alsa-lib successfully but error happened when to build Alsa-utils. =======================start build alsa-utils-1.0.23==================== -------------->/home/tim/work/dev_board/tools/ALSA/alsa-utils-1.0.23 configure: WARNING: If you wanted to set the --build type, don't use --host.
