Linking a static C library (MIRACL) to ns-3

[Sai Kishore]

I'm trying to use MIRACL library in ns-3. I downloaded the MIRACL library and trying to link the static library (miracl.a)  with ns-3 so that I can use those cryptographic functions in my program. Normally, if I were to run a program using the above mentioned library, I would run with the following command

gcc -m32 myprog.c miracl.a -o myprog.out

With that in mind, I started off with the following changes in the waf script.

    

    obj = bld.create_ns3_program('myprog', ['internet', 'mobility', 'wifi', 'mesh'])

    obj.source = 'myprog.cc'    

    obj.env.append_value("CCFLAGS", ["-I/home/yoda/miracl","-m32"])  

    obj.env.append_value("LINKFLAGS_EXTRA",["-L/home/yoda/miracl/miracl.h"])

    obj.env.append_value("STATICLIB",["miracl"])

    obj.env.append_value("LINKFLAGS",["-L/home/yoda/miracl"])

Now when I run the ns-3 program using the following command

./waf --run examples/tutorial/myprog

I get the following error saying it didn't find the header file. I made sure the path to the header file (miracl.h) and the static library (miracl.a) is correct

../examples/tutorial/myprog.cc:59:22: fatal error: miracl.h: No such file or directory

compilation terminated.

I don't know if I'm missing any flags that need to be set. Could anyone please help me with this?

Thanks,

John

Have a look at this post

I don't know if there is any change in the waf system that might need to be considered.

Hi Konstantinos

Thanks for the link. I recall going through it before but didn't really help much. I just tried something and it took me a little further but I'm still having problems. I modified 

obj.env.append_value("CCFLAGS", ["-I/home/yoda/miracl","-m32"]) 

to 

obj.env.append_value("CXXFLAGS", ["-I/home/yoda/miracl","-m32"]) 

This helped ns-3 find the header file "miracl.h" but now I get a bunch of "undefined reference" errors such as follows

/home/user/ns3/ns-allinone-3.18/ns-3.18/build/../examples/tutorial/mesh.cc:286: undefined reference to `mirvar(int)'

Although all these functions are mentioned as "extern" functions in the header, it is still not able to find these functions. 

Any thoughts??

I know this is an old thread but I'm having the exact same problem... Did you find how to get rid of the 'undefined reference' compiler errors?

Thanks!
