Hi, I have (sort of) 2 questions:
Background:
I was doing some coding using Phobos, and recently switched to using Tango.
1. I'm trying to build using dsss and it says :
/usr/bin/ld: cannot find -lphobos
collect2: ld returned 1 exit status
--- errorlevel 1
Command /usr/bin/rebuild returned with code 65280, aborting.
Error: Command failed, aborting.
You have to change your default rebuild configuration file. It's located
in /etc/rebuild/default on Posix systems. Change the "profile" value to
"dmd-posix-tango". Looking at the "dmd-posix" file, you can see, in the
link section, that it explicitly links to "phobos" which is not
necessary (at least not anymore). That's why you get the linker error.
Then I have a shellscript that links all the object files that dsss produced
together :
cd dsss_objs/D
dmd -v *.o -L-ldl ~/d/lib/libDerelictSDL.a ~/d/lib/libDerelictSDLImage.a
~/d/lib/libDerelictGL.a ~/d/lib/libDerelictGLU.a ~/d/lib/libDerelictUtil.a
/usr/lib/libSDL_image.a
Which outputs:
gcc flb.gui.boxmaker.o flb.gui.fontdata.o

And this generates a binary file which seems to work.
However, it leaks memory as if the GC is not actually working at all. (I have
some word wrap
code that allocates dynamic arrays and returns them to the caller .. which has
them in a local
variable and later discards them)
Valgrind reports that as a leak ...
If I manually delete some intermediate arrays, it leaks less...
Isn't the GC supposed to be able to free the memory?
I think that the GC doesn't give back memory to the system. It keeps it
for future use.
