Hi Prasad,
Regarding cross compilation we have some queries 1. We
are able to cross compile libosmocore commit 8649d57f507d359c99a89654aac7e19ce22db282
and some of later versions using local >talloc files, but there is a dependency of
talloc library in latest version.
Let us know which talloc version to pick and any specific procedure to cross compile
talloc source.
New libosmocore requires talloc version > 2.0.1. I followed instruction here
https://wiki.samba.org/index.php/Waf#cross-compiling to cross-compile talloc 2.0.8
export
CC=~/MentorGraphics/Sourcery_CodeBench_Lite_for_ARM_GNU_Linux/bin/arm-none-linux-gnueabi-gcc
./configure --cross-compile --cross-answers=arm.txt --hostcc=arm-none-linux-gnueabi-gcc
--disable-python --prefix=$SYSROOT/usr
make
make install
NOTE: Replace UNKNOWN to OK in arm.txt until the configuration has no error
2. We see that there is ARM cross compiler described
at http://bb.osmocom.org/trac/wiki/GnuArmToolchain. Let us know if this is usable with
NURAN boards.
I have never tried this compiler yet.
3. There is an error while linking osmo-pcu
arm-none-linux-gnueabi/bin/ld: ./.libs/libgprs.a(gprs_bssgp_pcu.o): undefined reference
to symbol 'tlv_parse@@LIBOSMOGSM_1.0'
/home/pkaup/osmo/latest/libosmocore/src/gsm/.libs/libosmogsm.so: error adding symbols:
DSO missing from command line
And the final linking command for osmo-pcu is
echo " CXXLD " osmo-pcu;/bin/bash ../libtool --silent --tag=CXX
--mode=link arm-none-linux-gnueabi-g++ -march=armv5te -marm -mthumb-interwork -Wall -ldl
-pthread -O2 -pipe -g >-feliminate-unused-debug-types -fpermissive -lrt -Wl,-O1
-Wl,--hash-style=gnu -Wl,--as-needed -o osmo-pcu pcu_main.o libgprs.la
>/home/pkaup/osmo/latest/libosmocore/src/gb/.libs/libosmogb.so
/home/pkaup/osmo/latest/libosmocore/src/.libs/libosmocore.so
>/home/pkaup/osmo/latest/libosmocore/src/gsm/.libs/libosmogsm.so
As I see, tlv_parse is part of libosmogsm which is getting linked.
Can you let me know the final linking command (corresponding output as above of
"make -n" in your setup ) so that I can cross-verify ?
Please see attachment.
