Hello,
I'm trying to cross compile rauc.io for my target.
What I do:
Include the path to the compiler to the PATH variable.
./autogen.sh
./configure --host=arm-linux-gnueabihf --with-sysroot=PATH_TO_MY_SYSROOT
make
There are 2 problems:
1. sysroot is ignored:
-------------------------------------
./include/bundle.h:3:25: fatal error: openssl/cms.h: No such file or
directory
#include <openssl/cms.h>
-------------------------------------
There is no -I entry in the compiler call to my sysroot
2. Headers are searched on the host
-------------------------------------
/usr/include/x86_64-linux-gnu/sys/cdefs.h:467:49: error: missing binary
operator before token "("
#if __GNUC_PREREQ (4,8) || __glibc_clang_prereq (3,5)
-------------------------------------
There is an entry -I/usr/include/x86_64-linux-gnu in the compiler call.
This is the first compiler call: (printed with make -n)
-------------------------------------
echo " CC " src/librauc_la-bootchooser.lo;/bin/bash ./libtool
--silent --tag=CC --mode=compile arm-linux-gnueabihf-gcc -std=gnu99
-DHAVE_CONFIG_H -I. -I./include -include ./config.h

-I/usr/include/x86_64-linux-gnu -g -MT src/librauc_la-bootchooser.lo
-MD -MP -MF src/.deps/librauc_la-bootchooser.Tpo -c -o
src/librauc_la-bootchooser.lo `test -f 'src/bootchooser.c' || echo
'./'`src/bootchooser.c
-------------------------------------
If I remove the entry -I/usr/include/x86_64-linux-gnu and add the enty
-IPATH_TO_MY_SYSROOT/usr/include at least this command succeeded.
I'm using the source code tags with v1.4
According to the documentation rauc.io can be cross compiled.
What I'm doing wrong?
Thanks.
Regards Simon
