I had installed the package libtcmalloc-minimal0
but when I try to compile my program with flag
-ltcmalloc-minimal0
I am getting error
/usr/bin/ld: cannot find -ltcmalloc_minimal0
I had checked /usr/lib and the library is there
More Info
dpkg gives following o/p
dpkg -L libtcmalloc-minimal0

and library is also 64 bit

You can't link simply to a file with -l if it doesn't end exactly with .so, since the linker assumes a particular naming convention (lib*.so).
You have several choices:
Install libtcmalloc-minimal0-dev if it exists, which should provide the .so dynamic link.
Create the symlink yourself: cd /usr/lib; ln -s libtcmalloc_minimal.so.0.0.0 libtcmalloc_minimal.so; cd -
Link directly to the library without the symlink by using gcc test.c /usr/lib/libtcmalloc_minimal.so.0.0.0
Link using the -l option using the full name: -l:libtcmalloc_minimal.so.0.0.0
