Defeating the time complexity of Python Dictionary

Unable to build Botan for Android on Windows

QUESTION

Defeating the time complexity of Python Dictionary

Asked 2021-Nov-22 at 13:02

I have a Python dictionary whose keys are Strings consisting of lower-case English alphabets and values are ints. Moreover, there are exactly 5e6 unique keys, all of them are Strings with lengths of exactly 10. Surprisingly, the lookup isn't taking much time. I was expecting the execution to take around 4s or more, but it is not exceeding 2.5s.

I converted the Python code to C++, the analogy of Dictionary being a map. I tried with map, unordered_map and gp_hash_table, while all of them were taking more than 2s in C++.

Here's the Generator I've used to generate the unique strings.

Unable to build Botan for Android on Windows

Asked 2020-Mar-21 at 22:13

I cannot understand how to build Botan for android, according on the instruction here:

$ export CXX=/opt/android-ndk/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android28-clang++

$ ./configure.py --os=android --cc=clang --cpu=arm64

i cannot understand how to use this commands on Windows, also reading previous issues did not help me, can you tell me how did you build this library on windows step-by-step, just your command examples?

I used --cc-bin option of configure.py to specify the path to the compiler, it is considered a solution for windows, but what i have is:

It seems Botan support for building Android binaries on Windows hosts is limited. You will have to use dark magic to make this work.

The build process consists of two phases, the configuration phase and the make phase.

The Android-specific instructions in the documentation you linked do not cover the whole build process, only the configuration phase. For the make phase, you then have to follow the Windows-specific instructions (link).

Configuration phase:

You will need the following binaries, adjust the paths to your machine:

clang++ (note the .cmd at the end): C:\Development\android-ndk-r19c-windows-x86_64\android-ndk-r19c\toolchains\llvm\prebuilt\windows-x86_64\bin\armv7a-linux-androideabi28-clang++.cmd
ar: C:\Development\android-ndk-r19c-windows-x86_64\android-ndk-r19c\toolchains\llvm\prebuilt\windows-x86_64\bin\arm-linux-androideabi-ar.exe

In the Botan folder, run the configure command:
