General / 64bit make in Android fails

« on: November 08, 2015, 02:13:09 pm »

Hi,
I recently tried to make sfml for armeabi in android, following the tutorial at https://github.com/SFML/SFML/wiki/Tutorial%3A-Building-SFML-for-Android. It works without any issue and same goes for 32 bit architectures such as armeabi-v7a, x86, mips etc.

But once I try a 64bit platform such as arm64-v8a, mips64 or x86_64, an error is thrown. It's got something to do with missing JPEG LIBRARY. Could anyone take a look at it?

cmake -DANDROID_ABI=x86_64 -DCMAKE_TOOLCHAIN_FILE=../../cmake/toolchains/android.toolchain.cmake ../..
-- Adjusting Android API level 'android-9' to 'android-21'
CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108 (message):
  Could NOT find JPEG (missing: JPEG_LIBRARY)
Call Stack (most recent call first):
  /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:315 (_FPHSA_FAILURE_MESSAGE)

  cmake/toolchains/android.toolchain.cmake:1565 (find_package)
  src/SFML/Graphics/CMakeLists.txt:119 (find_host_package)


-- Configuring incomplete, errors occurred!
See also "/home/suhairzain/Downloads/SFML-2.3.2/build/x86_64/CMakeFiles/CMakeOutput.log".

This is the content of CMakeOutput.log

The target system is: Linux - 1 - x86_64
The host system is: Linux - 3.19.0-32-generic - x86_64

What could be the issue? The page lists 'other valid targets' as: armeabi-v7a, mips, and x86.

You can repeat the following steps for all available architectures. Unfortunately, you can't build all targets for SFML at once. The following lines create a armeabi build. If you'd like to build for any other target, just replace all occurences. Other valid targets would be armeabi-v7a, mips, and x86.

Is there some extra configuration to be done for 64bit architectures?

[EDIT]
Looking at https://github.com/SFML/SFML/tree/master/extlibs/libs-android, there are only 32bit architectures. How can I build it for the 64bit architectures?

General / Integrate SFML into existing Android application

« on: November 06, 2015, 07:40:17 pm »

Hi,
I tried the Android example app and it works fine. But I would like to integrate SFML into an existing Android app. i.e; I have implemented a part of the app using the Android SDK but for a specific functionality (rendering of a custom layout to be exact), I cannot go with Android SDK. Thus I decided to give SFML a try.

Is it possible that I can use SFML only for a specific portion of the app? Like, integrate it into an Activity which can be called from another Activity implemented using Android SDK(Java)? Have anyone successfully done something like that?

Graphics / Query about including Harfbuzz in SFML

« on: November 05, 2015, 09:57:54 pm »

Hi,

As mentioned at http://en.sfml-dev.org/forums/index.php?topic=19293.0, I need to display complex text layout in my app. I was directed to the github issue https://github.com/SFML/SFML/issues/246.

According to the PR at https://github.com/SFML/SFML/pull/624, a way to make Harfbuzz a part of SFML was given, but it was rejected/postponed for the following reasons: https://github.com/SFML/SFML/pull/624#issuecomment-57596111.

One of the reasons mentioned is the use of a LGPL licensed library. But I believe harfbuzz has a new version now which is licensed under the "Old MIT" license as given at https://github.com/behdad/harfbuzz/blob/master/COPYING, so one less reason to not use Harfbuzz right?

Also, as specified at https://github.com/SFML/SFML/issues/799#issue-58459076, freetype 2.5.3 can be configured to use Harfbuzz, whereas SFML uses a 2.5.5+ version.

Is there any way I implement the complex layout without going through a lot of manual source code changes, either using Harfbuzz or some other SFML implementation?

Graphics / Issues while displaying Indian text (Malayalam)

« on: November 03, 2015, 12:25:35 pm »

Hi,
I'm trying to display a UTF-8 encoded malayalam text obtained from Wikipedia which is as follows: ദയവായി ഈ താളിലെ വിവരങ്ങൾ തർജ്ജമ ചെയ്യരുത്

This is how it is supposed to be displayed (screenshot from Firefox):


How it is actually displayed:


I had installed SFML using the libsfml-dev package in ubuntu, as described in http://www.sfml-dev.org/tutorials/2.0/start-linux.php.
The version, as obtained by dpkg -s is 2.1+dfsg-4ubuntu2

I spent a whole day on figuring this out to no avail. Could you help me out? The 1.6 version had a characterSet option (http://www.sfml-dev.org/tutorials/1.6/graphics-fonts.php). Was it removed in this version?

Following is my code:

Code: [Select]

sf::Font font { };
//sf::Uint32 mlCharset[] = {0x0d01, 0x0d02, 0x0d03, 0x0d04, 0x0d05, 0x0d06, 0x0d07, 0x0d08, 0x0d09, 0x0d0a, 0x0d0b, 0x0d0c, 0x0d0d, 0x0d0e, 0x0d0f, 0x0d10, 0x0d11, 0x0d12, 0x0d13, 0x0d14, 0x0d15, 0x0d16, 0x0d17, 0x0d18, 0x0d19, 0x0d1a, 0x0d1b, 0x0d1c, 0x0d1d, 0x0d1e, 0x0d1f, 0x0d20, 0x0d21, 0x0d22, 0x0d23, 0x0d24, 0x0d25, 0x0d26, 0x0d27, 0x0d28, 0x0d29, 0x0d2a, 0x0d2b, 0x0d2c, 0x0d2d, 0x0d2e, 0x0d2f, 0x0d30, 0x0d31, 0x0d32, 0x0d33, 0x0d34, 0x0d35, 0x0d36, 0x0d37, 0x0d38, 0x0d39, 0x0d3a, 0x0d3b, 0x0d3c, 0x0d3d, 0x0d3e, 0x0d3f, 0x0d40, 0x0d41, 0x0d42, 0x0d43, 0x0d44, 0x0d45, 0x0d46, 0x0d47, 0x0d48, 0x0d49, 0x0d4a, 0x0d4b, 0x0d4c, 0x0d4d, 0x0d4e, 0x0d4f, 0x0d50, 0x0d51, 0x0d52, 0x0d53, 0x0d54, 0x0d55, 0x0d56, 0x0d57, 0x0d58, 0x0d59, 0x0d5a, 0x0d5b, 0x0d5c, 0x0d5d, 0x0d5e, 0x0d5f, 0x0d60, 0x0d61, 0x0d62, 0x0d63, 0x0d64, 0x0d65, 0x0d66, 0x0d67, 0x0d68, 0x0d69, 0x0d6a, 0x0d6b, 0x0d6c, 0x0d6d, 0x0d6e, 0x0d6f, 0x0d70, 0x0d71, 0x0d72, 0x0d73, 0x0d74, 0x0d75, 0x0d76, 0x0d77, 0x0d78, 0x0d79, 0x0d7a, 0x0d7b, 0x0d7c, 0x0d7d, 0x0d7e, 0x0d7f};
font.loadFromFile("fonts/ml.ttf");

sf::Text text{};
text.setFont(font);
text.setString(L"ദയവായി ഈ താളിലെ വിവരങ്ങൾ തർജ്ജമ ചെയ്യരുത്");

For additional info, the specification for the Malayalam language is at http://www.fileformat.info/info/unicode/block/malayalam/list.htm, if you need it.
