How to recompile ntl and gmp libraries with “-fPIC” flag & make HELib as a shared library &...
a C++ code built into a shared library for HELib is using NTL and GMP static library. But it gets following error:
/usr/bin/ld: /usr/local/lib/libntl.a(FFT.o): relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libntl.a: error adding symbols: Bad value
collect2: error: ld returned 1 exit status
It was suggested int the post Click here
to recompile NTL and GMP with "-fPIC " flags.
I'am not able to find how I should do that.
Edit:
I'm able to build the shared library now after :
recompiling GMP and NTL by:
./configure --enable-shared
for gmp and
./configure SHARED=on
After make Install of HELib. I get error when I run the example codes.

Why are you linking a dynamic library with a static one? Other than that, please read some doc, even.../configure --helpgives the answer...

If you are getting the same error, it may be that you have several versions of the lib and it isn't picking the right one. Also, I wonder on what system you are that you need to compile GMP/NTL yourself. Anyway, to answer your question, for GMP, try./configure --help | grep -i pic.

Since all your link errors involve istream/ostream and you are using C++11, I suspect an incompatible ABI. Did you compile HElib with the same compiler and options as the example?nm -CD /usr/local/lib/libfhe.soand see what looks closest to those undefined references.

Marc Glisse provided the answer for the first two parts of the question.For the third part "Undefined Reference error" the answer is I'd not compiled and linked a x.cpp containing the functions that caused the undefined reference into my shared library. hence check : nm -CD /usr/local/lib/libfhe.so to see if these functions are listed with a linking address or not. If not then check which code provides this functionality. Link that code to the shared library.
