$ dmd -I/path/to/DerelictSDL2/source
-I/path/to/derelict-util-2.0.6/source main.d
/path/to/DerelictSDL2/lib/libDerelictSDL2.a
/path/to/derelict-util-2.0.6/lib/libDerelictUtil.a -gc
It compiles but on running crashes (as shows valgrind) in
SDL_FillRect function.
BUT in gdb it runs successfully and I see red window.
What I'm doing wrong? How gdb can make not working code working?
dmd 2.071.1
Thank you!
I tried your code in Arch x86_64 using dub and it worked for me.
This is the dub file I used:
---
name "testsdl"
targetType "executable"
dependency "derelict-sdl2" version=">=2.0.0"
dependency "derelict-util" version=">=2.0.6"
dependency "derelict-gl3" version=">=1.0.18"
---
If you're not familiar with dub and want to test these are the
steps I took.
0. Get dub [1]
1. mkdir -p testsdl/source
2. Copy your source code from OP into a file
"testsdl/source/app.d"
3. Copy the above dub config into a file "testsdl/dub.sdl"
4. cd testsdl; dub build
It should pull in the dependencies and build a program called
"testsdl".
bye,
