These also have Linux support, and form a part of the bundle's premium tier, which can be unlocked by paying a price higher than the average.Īs the Humble Bundle goes, gamers can pay 'any price' and get the first few (four, for this bundle) games free. The new additions to the bundle are Secret of the Magic Crystals, Strata and Doodle God. Make sure ld is able to find it.The Humble PC and Android Bundle 13 has been updated with three new games. You can keep it in any directory of your project or workarea, as this is runtime linking. If you build it on x86, you must also tell the system where the. This is the reason, you need to run the executable file only on the same target machine type. so is cross compiled for a specific arch type and that is ARM where as out host machine is x86 based linux. :/demo# readelf -h libopencv_tiny.soĮLF Header: Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: DYN (Shared object file) Machine: ARM Version: 0x1 Entry point address: 0x0 Start of program headers: 52 (bytes into file) Start of section headers: 3561860 (bytes into file) Flags: 0x5000200, Version5 EABI, soft-float ABI Size of this header: 52 (bytes) Size of program headers: 32 (bytes) Number of program headers: 8 Size of section headers: 40 (bytes) Number of section headers: 27 Section header string table index: 26ĭid you get it? Ok, let me just say it: The. demo, that you want to link with created the. Let us say we have following code in the file demo.cpp inside directory. However, if you want to make it android complaint you can rename it to libopencv_java3.so Step 9: Linking with sample code Do not worry it is just a file name and it will still work. Often it is given the name libopencv_java3.so where 3 is the version. Now, your shared object ( libopencv_tiny.so ) is ready for android deployment. This demo has been tested on the following Environment and library versionsĪndroid is a versatile OS and can run on multiple hardwares, from mobile phones to IOT devices, Raspberry Pi, to various single board computers and therefore it is important to cross compile the code for that particular Instruction Set Architecture (ISA).Īs we are building OpenCV for Android, we would need its built tools called Native Development Kit (NDK). In this tutorial we will create a dynamic library (i.e. Dynamic LibraryĪ library can be compiled statically along with your application code.Īlternatively, it can be dynamically linked at runtime. Hence, it makes perfect sense to include what is required and leave out the rest. OpenCV is an awesome library with tons of Computer Vision algorithms but usually, you use a small subset of these algorithms in your application. In a mobile environment like Android, if you choose OpenCV for production, one of your important goals is to bring down the size of the library and also make it performance ready.
