Hi all,
For some reasons, I need to integrate an arm toolchain supported
iwmmxt into scratchbox environment.
I have built the toolchain by crosstool-0.42 via simply executing
modified demo-arm-iwmmxt.sh in i386 target of scratchoxbox.
Flowing is my enviroment:
OS: UBuntu 6.10
host glibc: 2.4
Scratchbox: 1.0.6
i386 target of scratchbox: cs2005q3.2-glibc-i386
arm-iwmmxt.dat of crosstool:
KERNELCONFIG=`pwd`/arm.config
TARGET=arm-iwmmxt-linux-gnu
TARGET_CFLAGS="-O"
GCC_EXTRA_CONFIG="--with-cpu=iwmmxt
--enable-cxx-flags=-mcpu=iwmmxt --disable-libmudflap --disable-libssp
--disable-libstdcxx-pch --with-float=soft"
GLIBC_EXTRA_CONFIG="--without-fp"
By http://www.scratchbox.org/wiki/ForeignToolchains, I setup an
target for this new toolchain and try to execute the init_tests.sh
located in
/scratchbox/packages/tests/init/.
Here is the output message of init_tests.sh:
[sbox-iwmmxt: /scratchbox/packages/tests/init] > ./init_tests.sh

Starting test: strip
Finishing test: strip, result: OK
Starting test: execute
Hello world!
Hello world!
Finishing test: execute, result: ERROR
My first question is that even the result of first two execution
seems to be ok.
However, after directly executing "arm-iwmmxt-linux-gnu-hello"
located in "my-toolchain/tmp"
I can't see any standard output in my console in scratchbox.
By the means of redirect the output result of
"arm-iwmmxt-linux-gnu-hello" to the file, I find that the "Hello
world" message is saved in the file.
The second question is why last two execution failed.
It seems to be some problem of executing c++ program.
Is it relative to QEMU or GLIBC?
Best regards.
