make test
sudo make install

The command above builds the static library and cryptest.exe program. It also uses a sane set of default flags, which are usually "-DNDEBUG -g2 -O3 -fPIC".
If you want to build the shared object, then issue:
make static dynamic cryptest.exe
@ -47,20 +49,32 @@ If you would like to use a different compiler, the set CXX:
export CXX=/opt/intel/bin/icpc
make
Or:
CXX=/opt/solarisstudio12.4/bin/CC make
If you want to build using C++11, then:
make CXXFLAGS="-std=c++11"
export CXXFLAGS="-DNDEBUG -g2 -O3 -std=c++11"
make
Or:
CXXFLAGS="-std=c++11"
make
CXXFLAGS="-DNDEBUG -g2 -O3 -std=c++11" make
LLVM's libc++ is also supported, so you can:
CXXFLAGS="-std=c++11 -stdlib=libc++"
export CXXFLAGS="-std=c++11 -stdlib=libc++"
make
If you target 32-bit IA-32 machines (i386, i586 or i686), then the makefile forgoes -fPIC due to register pressures. You should add -fPIC yourself in this case:
CXXFLAGS="-DNDEBUG -g2 -O3 -fPIC" make
You can also override a variable so that only your flags are present. That is, the makefile will not add additional flags. For example, the following build with only -std=c++11:
make CXXFLAGS="-std=c++11"
