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 :-)

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.
