After googling this topic and finding nothing, I figured XDA was the place to go. I am looking for a way to get a C++ compiler working on my phone (mytouch slide) or android in general.
Thanks in advance
Que? Like a C++ compiler to compile for android? Why would u want this C++ don't run native on Android it must be called from java so it would be pointless.
There is an sdl port around that required zero knowledge of.java but I believe it still has to compile the java each time. If not it could be possible...

I don't want to run the programs on my phone, just compile
Compile for what?
What is the Android NDK?
The Android NDK is a toolset that lets you embed components that make use of native code in your Android applications.
Android applications run in the Dalvik virtual machine. The NDK allows you to implement parts of your applications using native-code languages such as C and C++. This can provide benefits to certain classes of applications, in the form of reuse of existing code and in some cases increased speed.
The NDK provides:
* A set of tools and build files used to generate native code libraries from C and C++ sources
* A way to embed the corresponding native libraries into an application package file (.apk) that can be deployed on Android devices
* A set of native system headers and libraries that will be supported in all future versions of the Android platform, starting from Android 1.5
* Documentation, samples, and tutorials
The latest release of the NDK supports these ARM instruction sets:
* ARMv5TE (including Thumb-1 instructions)
* ARMv7-A (including Thumb-2 and VFPv3-D16 instructions, with optional support for NEON/VFPv3-D32 instructions)
Future releases of the NDK will also support:
* x86 instructions (see CPU-ARCH-ABIS.TXT for more information)
ARMv5TE machine code will run on all ARM-based Android devices. ARMv7-A will run only on devices such as the Verizon Droid or Google Nexus One that have a compatible CPU. The main difference between the two instruction sets is that ARMv7-A supports hardware FPU, Thumb-2, and NEON instructions. You can target either or both of the instruction sets — ARMv5TE is the default, but switching to ARMv7-A is as easy as adding a single line to the application's Application.mk file, without needing to change anything else in the file. You can also build for both architectures at the same time and have everything stored in the final .apk. For complete information is provided in the CPU-ARCH-ABIS.TXT in the NDK package.
The NDK provides stable headers for libc (the C library), libm (the Math library), OpenGL ES (3D graphics library), the JNI interface, and other libraries, as listed in the section below.
The NDK will not benefit most applications. As a developer, you will need to balance its benefits against its drawbacks; notably, using native code does not result in an automatic performance increase, but does always increase application complexity. Typical good candidates for the NDK are self-contained, CPU-intensive operations that don't allocate much memory, such as signal processing, physics simulation, and so on. Simply re-coding a method to run in C usually does not result in a large performance increase. The NDK can, however, can be an effective way to reuse a large corpus of existing C/C++ code.
Please note that the NDK does not enable you to develop native-only applications. Android's primary runtime remains the Dalvik virtual machine.
The ndk allows u to use c++ c/c++ code in Android. That code must be called from java tho.

I don't think you guys are understanding his question... He's not looking to write apps for Android... he's writing stuff in C++ (presumably for desktop or maybe other embedded applications, I dunno) and just wants to be able to compile that code on his Android device...
Now as far as an answer to that question, they did kinda cover it... Since pretty much everything in Android runs in Java, I believe it would be pretty difficult to write a C++ compiler that could run on Android.
To install an compiler in your Android device, google around for how to install Debian in it. Don't be afraid, you install it in parallel of Android, you will need a command or terminal window as well (available in the marketplace).
Debian comes with everything you need to compile in your device.
I hope I was useful.
Cheers
Thank you abrigham for clearing that up for me. You are exactly correct.
Ernestus, that seems like it would cause more problems then it would be worth
hmm.. i was googling for this as well.. thought it'll be useful to have this around.

Next best option then is to cross-compile to Android/ARM from another platform. The arm-eabi toolchain provided by Google's NDK is one option as others have already mentioned.
Codesourcery ARM toolchain is another, for Linux i686 theres link to the downloadable archive see this post (search for 'wget THISLINK' text on that page).

Installing debian isn't too bad, and would give you the most flexibility for compiling on the phone.
You could also ssh into another computer using connectbot or some other terminal and code/compile remotely.
Another way to do remote compiles is continuous integration. Edit/upload the file to your repository, and using a server such as Jenkins, run the compile and view the results through the browser or an app such as Hudson2Go. Jenkins will also auto-compile on edits and can send you a text if the build fails. Jenkins is very easy to setup.
Try finding an online c++ compiler or you could connect to a windows or linux machine/server to upload andcompile your c++ files.

Use "c4droid" this is a paid app.. anywy if you like search on the market.
Another alternitiv is out there now. Not sure how good it works.
C / C++ Compiler
im looking for compiler too i found i market a4droid compiler but it costs... and i couldnt find enywhere free apk
Easiest thing to do would be a chroot Linux environment from an existing distribution, like Ubuntu. Then compilers for nearly any language you can think of are an "apt-get install" away.
If you're running CyanogenMod 7, you have a large SD card, and you don't mind repartitioning the SD card and shaving off 2 GB or 4 GB for Linux, then I'll be posting a howto in the next day or two. I have Ubuntu 11.10 Oneiric Ocelot running out of /sd-ext cleanly, using only files from official sources (<32 MB file from cdimage.ubuntu.com and everything else via apt/dpkg with signature verification) rather than from rapidshare-like sites.
Or about a year ago there were instructions posted for unzipping a ~2 GB image containing an older version of Ubuntu downloaded from a filesharing site. You could do that if you have an immediate need.
you can download from my blog
http://dateno1.egloos.com/855501
it from https://market.android.com/details?id=com.n0n3m4.gcc4droid&feature=more_from_developer
it has some library problem but work well (i already compile few binary for my phone )
I think c4droid maches perfectly what you were looking for. I'm using it to work on my projects "on the road" and so far it works pretty well.
A little tricky to set up, since you need "gcc plugin for c4droid" but to choose g++ compiler, and builds are saved at "data/data/com.n0n2m3.c4droid/files/temp" or something like that...
There's another option, but you still have to pay: DroidEdit Pro. Perhaps better editor (didn't test it though) but without it's own compiler, you have to set up an external compiler from sftp server.

Architekt is a custom Virtual Machine that can be used with Mac OSX, Windows, and Linux. It includes everything you need to sync with the repo of your choice (Cyanogenmod, AOKP, AOSP, etc) and start compiling Android ROMs. This version includes Java 6 for compiling Gingerbread thru Kitkat. To compile Android L, switch to OpenJDK7.
Features:
- Latest Arch system
- XFCE Desktop Environment
- All necessary packages for compiling
- No junk (games, etc)
- Geany for editing code
All you have to do is download the source!
The only requirement is that your host machine supports a 64 bit OS. 32 bit systems will not work!
Instructions:
1. Download and install VirtualBox for your host system from here.
2. Download the latest architekt zip archive and extract architekt.ova to your hard drive.
3. Start VB, click File > Import Appliance. Select "Open Appliance" and choose architekt.ova, then click Next to import the virtual machine.
4. Highlight architekt in VirtualBox Manager and open Settings. Under "System" you will want to give it more RAM and Processor Cores. The higher these values are, the faster you will compile ROMs.
5. Start the machine, pull up a terminal and initialize a git repo. Once the source is finished downloading, you're ready to go!

please can you help me how to change java version jdk6 to jdk7 using command?I've tried command that used in ubuntu but Those command are not working in this virtual machine. Also there is no app to extract file and can't edit xml file

You might want to try BuilduntuVM instead.
Architekt is getting pretty dated, and I don't have any time or plans to update it. BuilduntuVM received a lot more attention and is up to date with the latest versions of OpenJDK etc. for compiling Android M.

Hi,
I've setup an own partition with ubuntu and prepare the system with the Git from AOKP.After reading some files (Readme in the git) I've initialize the git, that I've download all devices and driver. Uncomfortable I didn't found the 2 subs "device_acer_A510" and "vendor_acer_A510". Also after "lunch" I didn't see something from Acer nor from the CPU type T30. ..
Before I want try to add an own subdirectory or make some own changes, I want try to compile the Rom from the current source.
Could someone tell me, where is my mistake or what I've forgotten?
I found some guides online to enable the Linaro Ranchu device, but no matter what I try I can't seem to get it to work in an emulator.
I'm attempting to port a ROM over to the Nexus 5x, which uses an Arm64 processor. However, I'm currently lacking a USB A-to-C cable so my only bet right now is ARM64 emulation. I first read about the possibility using Ranchu on the Linaro website. I understand that the code referenced in that article (and, indeed. the whole ARM64 emulator formerly known as emulator64-arm64 from what I've seen) has since moved to qemu-android.googlesource.com. So, I downloaded the Linaro devices tarball and dropped it into the Android source. This gave me a 'ranchu-eng' lunch combo.
I then used the following process to build the kernel and images:
Code:
cd kernel/goldfish
../../prebuilts/qemu-kernel/build-kernel.sh --arch=arm64 --out=../../prebuilts/qemu-kernel/arm64 --cross=aarch64-linux-genu- --config=ranchu -j8
croot
lunch ranchu-eng
make -j8
This builds without issue, but I can't seem to emulate it for the life of me. Using the commands from that Linaro article, qemu crashes saying something along the lines of "bad address 0x00000024". Trying to run emulator-arm64 results in an error along the lines of '-cpu: option not found'. How can I emulate an ARM64 system? Also, since there are no Arm64 system images any longer (apparently, there used to be there), I can't use an AVD device for the emulator.
How can I do Arm64 emulation for Android development?
I have a few questions, they are as follows:
1) Is virtualbox (or any vm) suitable for rom development?
2) what is a suitable fixed drive size for installing Ubuntu? Or should i use dynamically allocated drive?
3) which version of ubuntu is recommended? (The current 16.04.1 release is laggy) (I'm on a 4gb ram machine with one core)
4) what tools/programs are necessary for rom porting from source code (git)? And what should i install for said task?
