how to install DLangIDE on Debian Wheezy

how to install DLangIDE on Debian Wheezy:

 - get the source from here:  https://github.com/buggins/dlangide or

git clone https://github.com/buggins/dlangide.git
cd dlangide
dub run

This will fail with

"
Derelict: cannot load freetype shared library: Failed to load symbol FT_Gzip_Uncompress from shared library libfreetype.so.6
"

or

"
2015-02-23 16:16:06.462 E No font files found!!!
2015-02-23 16:16:06.463 E Currently, only hardcoded font paths implemented.
2015-02-23 16:16:06.463 E Probably you can modify sdlapp.d to add some fonts for your system.

or

"
Failed to load symbol SDL_HasAVX from shared library libSDL2.so
"




or

"
SDL_CreateWindow failed - cannot create OpenGL window: No OpenGL support in video driver
"

No worries, will fix them next.

 - set the LD_LIBRARY_PATH to include /usr/local/lib if it does not include it already

export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH

 - install freetype from sources (configure, make, sudo make install) from here http://sourceforge.net/projects/freetype/files/freetype2/2.5.5/

 - install libxext-dev (required by SDL)

apt-get install libxext-dev

 - install libsdl2-dev from wheezy-backports: don't need it since we'll install from sources, but lots of other dependencies will be installed

apt-get -t wheezy-backports install libsdl2-dev

 - install SDL2 from sources (configure, make, sudo make install) from here https://www.libsdl.org/download-2.0.php

 - install ttf-dejavu ttf-dejavu-core ttf-dejavu-extra

apt-get install ttf-dejavu ttf-dejavu-core ttf-dejavu-extra

 - update dependencies

dub upgrade --force-remove

 - edit a file in DLangUI:

find the source for DLangUI in ~/.dub/packages/ and edit the file src/dlangui/platforms/sdl/sdlapp.d :

find the line "ft.registerFonts("/usr/share/fonts/dejavu/");" and add after it this line:

ft.registerFonts("/usr/share/fonts/truetype/ttf-dejavu/");


return to the folder with the sources for DLangIDE and run

dub build --force

and then

dub run

or

./bin/dlangide

and you should get the main window to open

Did not get further today, will update this post if I get into more snags.





To get autocompletion install dcd from http://d-apt.sourceforge.net/ .
