[LTP] LTP cross compilation

[LTP] LTP cross compilation

Hi all,

It is the first time that I use ltp and I am having some troubles trying 
to cross compile it.
I have seen a cross compilation example in the installation manual. It 
is about cross compiling for a powerpc processor.

CROSS_COMPILER=/opt/ppc64/powerpc64-linux/bin/powerpc64-linux-
CROSS_CFLAGS= -mpowerpc64
LDFLAGS=-static
LOADLIBES=-lpthread -lc -lresolv -lnss_dns -lnss_files -lm -lc
LIB_DIR=/lib64
export LOADLIBES LIB_DIR

In my case, I a compiling for an arm processor. I tried to do the same 
by the specifying the toolchain prefix, the CC, LD, AR and the LIB_DIR. 
But, I get always this error when cross compiling :

getdelays.c: In function 'print_delayacct':
getdelays.c:215: error: 'struct taskstats' has no member named 
'freepages_count'
getdelays.c:216: error: 'struct taskstats' has no member named 
'freepages_delay_total'
make[5]: *** [getdelays] Erreur 1

In fact, I omitted the libraries nss_dns and lnss_files since didn't 
find them in the lib directories of my toolchain. I am not sure about 
that, but I don't think the problem is related to this libraries since 
they do not exist in my host machine either, and here, the compilation 
of ltp worked well. Perhaps, the problem is due to the fact that I 
didn't put any option in the CROSS_CFLAGS since I found nowhere how to 
get this information.

If someone knows any thing about this or succeeded to cross compile ltp, 
it would be really nice if he could tell me, because I am really stuck 
now :-)

Thanks,

Hi all,

I think that I've figured out how to configure LTP for cross
compilation. In fact, we need to put the right parameters during the
configuration. We should append the cross toolchain's bin directory to
the path and add --host=$(toolchain_prefix) to the configure script. By
doing that, ltp succeds to find out the binary utilities that it should
use (gcc, ld ,ar, ranlib, ...). We should also specify the path to the
include and lib directory of the toolchain we are using by setting the
variables CPPFLAGS and LDFLAGS. However, I still get a compilation error
that I think it is related to the fact that some libraries are missing
(signalfd for example). The message I receive is this :

getdelays.c: In function 'print_delayacct':
getdelays.c:215: error: 'struct taskstats' has no member named
'freepages_count'
getdelays.c:216: error: 'struct taskstats' has no member named
'freepages_delay_total'

Does anyone know how to overcome this problem or does this mean that it
is not possible to cross compile LTP ? In fact, the crosstoolchains I am
using are generated using crosstool-ng. So, I don't think that the
problem is due to the toolchain.

Your code may be mismatched with the testcode which means the autoconf
stuff needs to be fixed.

[LTP] LTP cross compilation

[kamal p]

Hi,

   when I cross compiling the LTP i've faced an issue ,which is related to
linking error such as undefined reference to 'pthread_mutex_lock'. In
additon to './configure' i've given CFLAGS="-static"
LDFLAGS="-static-pthread" ..Is these was the correct? If no, please tell me
how will I cross compile LTP with relevent and clear procedure.

     Error which I got is as follows:
      make -C "lib" \
        -f

provide a space between -static and -lpthread. If you are making
bionic changes to LTP, then make it to pthread.
