|ERROR during compling omentpp4.1 on Ubuntu 10.04(Lucid) x86_64 bit||Quan Wei||7/3/12 8:39 AM|
I have test install omnetpp 4.1 on Ubuntu 10.04(Lucid) x86_64 bit. I encounter this bug when I type "make". I have cost one whole day trying to resolve this problem, but there is no idea. So I turn to help here. My akaroa version is 2.7.9. And the exact error informantion is shown as follows.
Thanks for any useful infrmation.

The solution is already written on your output:
"can not be used when making a shared object; recompile with -fPIC"i.e. you MUST compile your akaroa.a library using the -fPIC option to generate position independent code (as omnet is built usin PIC so all other libraries linked to it must also compiled that way).
Somehow you must add the -fPIC flad to the compiler's command line during the akaroa build process.

You mean recompling akaroa, not omnetpp. Thanks for your help, I will have a try tomorrow. Hope it successful.

First, thanks for Rudolf Hornig's help.
I have test recompling akaroa with "-fPIC" by add the flag in the Makefile.config_tools, whuch is shown as follows:
# Compilers and compilation flags
CC = gcc
CFLAGS = -g -Wno-deprecated -fPIC
CPLUS = g++
#CPLUS_FLAGS = -g -O
CPLUS_FLAGS = -g -Wno-deprecated -fPIC
# No optimisation
CPLUS_NOOPT_FLAGS = -g -fPIC
And then I recompile Omnet++, I am glad to see the error go away. :)
However, a similar error occurs next. The error informantion is shown as follows:
/usr/bin/ld: /usr/local/akaroa/lib/libakaroa.a(md5c.o): relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC
I have test modify the Makefile in the src/auth (because md5c.o is in this dir) by adding flag "-fPIC", but the error still exsit. :(
How to reslove it?

This problem is resloved, and I found a small bug in akaroa.
