[Bug] cross-compile tcpreplay for armv5 freescale

[dummys]

Hi,

Im trying to cross compile tcpreplay for armv5 but I get the following eror when doing it:
PS: libpcap is compiled successfully. I'm using two different toolchain, one from crosstool-ng rm-unknown-linux-gnueabi and arm-unknown-linux-gnueabihf but both fail with the same error:

In file included from ../../src/common/timer.h:31,
                 from ../../src/common.h:45,
                 from cidr.c:23:
/usr/include/math.h:462:21: error: '_Float128' is not supported on this target
 # define _Mdouble_  _Float128

My command is:

CC=arm-unknown-linux-gnueabi-gcc ./configure --host=arm-unknown-linux-gnueabi --with-libpcap=/home/build/cross-compiling/arm-32/libpcap-1.9.1_comp/compiled --prefix=/home/build/cross-compiling/arm-32/tcpreplay-4.3.3/compiled

Not sure why it is picking up the local math.h rather than the cross compiler's. Maybe get rid of --host=

Can you compile 64-bit?

[dummys]

no I can't because the target is x32

Without --host its failing:

If you meant to cross compile, use `--host'.
See `config.log' for more details

also tried with --target= same problem

I tried settings this :

set -x PATH "$PATH:/home/build/x-tools/arm-unknown-linux-gnueabi/bin/"
set -x CFLAGS "-march=armv5tej -mfloat-abi=soft"
set -x CC arm-unknown-linux-gnueabi-gcc

Then configure with:

./configure --host=arm-unknown-linux-gnueabi --with-libpcap=/home/build/cross-compiling/arm-32/libpcap-1.9.1_comp/compiled --prefix=/home/build/cross-compiling/arm-32/tcpreplay-4.3.3/compiled --with-sysroot=/home/build/x-tools/arm-unknown-linux-gnueabi/arm-unknown-linux-gnueabi/sysroot

Still picking the /usr/include/math.h from the host.

@fklassen do i need to cross compile tcpdump and libdnet too ?

[dummys]

i cross compiled libdnet, tcpdump also and use this now:

set -x PATH "/home/build/x-tools/arm-unknown-linux-gnueabi/bin/:/home/mofo/x-tools/arm-unknown-linux-gnueabi/arm-unknown-linux-gnueabi/sysroot/usr/include:$PATH"


set -x CPPFLAGS "/home/build/cross-compiling/arm-32/libpcap-1.9.1/compiled/lib/libpcap.so"


set -x LDFLAGS "/home/build/cross-compiling/arm-32/libpcap-1.9.1/compiled/lib/libpcap.so"

./configure --host=arm-unknown-linux-gnueabi --with-libpcap=/home/build/cross-compiling/arm-32/libpcap-1.9.1 --prefix=/home/build/cross-compiling/arm-32/tcpreplay-4.3.3/compiled --enable-static-link --with-tcpdump=/home/build/cross-compiling/arm-32/tcpdump-4.9.3/tcpdump --with-libdnet=/home/build/cross-compiling/arm-32/libdnet-1.11/compiled

And i get further the error of fpu error, but now I have another one popping:

Seems to be well known error on arm but tested all the fix and cannot find that works:

add ac_cv_func_malloc_0_nonnull=yes on configure

Check for AC_MALLOC in configure etc...

EDIT found a fix for this bug... remove the AC_FUNC_REALLOC in configure.ac

[dummys]

now I struggle with building a static tcpreplay version, its not possible despite I used "-static" everywhere I can, like in lddflags, cflags etc...

[fklassen]

It sounds like you found a fix similar to this.

You seem to have issues with your compiler. Unfortunately I would say you are on your won to figure out how to get static to work. You probably have issues with your libraries not containing static libraries.

[dummys]

yes but the problem of AC_FUNC_REALLOC is in your configure.ac. Not in my toolchain. It seems to be a error that appear mainly on cross compile for arm.

fixed in PR #641
