If I build a library (for example Quantlib: http://sourceforge.net/projects/quantlib/files/QuantLib/1.2/QuantLib-1.2.tar.gz/download), I see that my userid is encoded in the built library.

./configure --prefix=/usr/local --with-boost-include=/usr/include/boost --with-boost-lib=/usr/lib && make -j3 && sudo make install

$ grep rajanikanth /usr/local/lib/libQuantLib.*
Binary file /usr/local/lib/libQuantLib.a matches
Binary file /usr/local/lib/libQuantLib.so matches
Binary file /usr/local/lib/libQuantLib.so.0 matches
Binary file /usr/local/lib/libQuantLib.so.0.0.0 matches

Is this normal?

Is there anyway to prevent the userid from appearing in the locally built library?

Thanks,
Raj

    I see that my userid is encoded in the built library.

    This is most likely because

    1. you built the library with COPTS=-O2 -g (which is the default most configure scripts will use when building with gcc).
    2. you built it in your home directory, which looks like /home/rajanikanth or some such

    Is there anyway to prevent the userid from appearing in the locally built library?

    You can avoid this by building non-debug version (make -j3 CFLAGS=-O2), or by building it in a “generic” directory, e.g. /tmp/build-quantlib
