Trouble compiling Angband

**Nick** · December 27, 2017, 21:48

Try going into the file src\h-basic.h, removing these lines:

Code:

/**
 * Native MSVC compiler doesn't understand inline or snprintf
 */
#ifdef _MSC_VER
#	define inline __inline
#	define snprintf _snprintf
#endif

and see what happens.

Those lines were apparently to deal with deficiencies in the Microsoft compiler which look like they may have been fixed. Let us know how you go.

I'm down to 4 errors:

Error (active) E0028 expression must have a constant value Angband1 c:\Users\Robert\source\repos\Angband1\Angband1\loa d.c 808

Error C2057 expected constant expression Angband1 c:\users\robert\source\repos\angband1\angband1\loa d.c 808

Error C2466 cannot allocate an array of constant size 0 Angband1 c:\users\robert\source\repos\angband1\angband1\loa d.c 808

Error C2133 'itypes': unknown size Angband1 c:\users\robert\source\repos\angband1\angband1\loa d.c 808

line 808 from load.c looks like:

Code:

 	bitflag flags, itypes[itype_size];

OK, you can safely replace itype_size with ITYPE_SIZE in that line, which should fix that problem.

2 errors:
Error LNK2001 unresolved external symbol _init_sound_win Angband1 C:\Users\Robert\source\repos\Angband1\Angband1\sou nd-core.obj 1

Error LNK1120 1 unresolved externals Angband1 C:\Users\Robert\source\repos\Angband1\Debug\Angban d1.exe 1

I may end up having to start over from the beginning.
This is what I did since the visual studio instructions are out of date:

Added libpng.dll and zlib1.dll to project directory.
Added zlib1.lib(no such file, I tried renaming) libpng.lib msimg32.lib winmm.lib to Properties->Linker->Input->Additional Dependencies
Added all src ".h" and ".c" files, excluding files with "main" and snd-sdl.c to project directory and project.
Added all src\win ".h" and ".c" files to project directory and project.
Added all src\win angband.rc and angband.ico files to project directory and project.
Added all src\win\include ".h" files to project directory and project.
Added main-win.c file to project directory and project.

I think I'm going to wait to compile until there is an update for visual studio instructions. Thanks for the help.

Sorry, I missed your last post.

You could try replacing

Code:

errr init_sound_win(struct sound_hooks *hooks, int argc, char **argv);

in src/snd-win.h with

Code:

extern errr init_sound_win(struct sound_hooks *hooks, int argc, char **argv);

from where you were at that point, and see if that works.

I'm encountering this issue when compiling, and unfortunately adding the extern prefix did not fix the error.

One thing to try would be to either set SOUND in the preprocessor definitions (here's Microsoft's instructions, with the Visual Studio part at the bottom of the page, https://docs.microsoft.com/en-us/cpp...s?view=vs-2019 ; you're looking to set the equivalent of /DSOUND on the command line) or change line 61 of src/sound-core.c from

Code:

#if (!defined(WIN32_CONSOLE_MODE) && defined(WINDOWS) && !defined(USE_SDL) && !defined(USE_SDL2))

to

Code:

#if (!defined(WIN32_CONSOLE_MODE) && defined(WINDOWS) && !defined(USE_SDL) && !defined(USE_SDL2) && defined(SOUND))

That worked! Thank you!!
I'm also getting a few other errors similar to the previous one, but I'll see if I can work around these. Here are the other errors for reference:

For all but the last one, did you add the .c and .h files from src\win to the project? FreeDIB(), ReadDIB2_PNG, default_layout_win(), and SaveWindow_PNG() are defined in those files (src\win\readdib.c , src\win\readpng.c , src\win\win-layout.c , and src\win\scrnshot.c ).

The last one is likely due to the choice of the project type. This question and the posted answers at StackOverflow, https://stackoverflow.com/questions/...nction-int-cde , may help with that.

Wow, facepalm. That works, it's built now. Thank you! I feel embarrassed now, but I'm realized I think I skipped it when following the step-by-step guide because when I realized steps 9-11 were unnecessary to build/pointing to the wrong directories, my brain just glossed over step 12 too.

Anyway, thank you again. I'm on my way to poking around with the code now.

Edit: Funny story, it turns out that running the executable that was built results in this weird error message

Code:

---------------------------
牅潲r
---------------------------
慃湮瑯映湩⁤敲畱物摥搠物捥潴祲਺汉扩\
---------------------------
OK   
---------------------------

From which google translate gives me:

Code:

---------------------------
牅潲r
---------------------------
慃湮瑯映湩Knock on the leftovers 摥搠物捥潴祲han expansion\
---------------------------
OK

From what I see in Microsoft's documentation, the Win32 API switches from expecting ANSI encoded strings to 16-bit encoded character strings if the UNICODE preprocessor macro is set. It looks like the project settings in src\win\vs2019 don't set that macro. Is it possible that when you set up your project that it set UNICODE by default? That could explain the garbled message and getting rid of UNICODE and then recompiling would get you an executable that produced interpretable messages.

Besides the SOUND preprocessor macro you ran into earlier, another macro that appears in the src\win\vs2019 project settings but isn't mentioned in angband_visual_studio_step_by_step.txt is USE_PRIVATE_PATHS - that affects where things like the save file and high score file are placed. For the record, here are the preprocessor macros set in src\win\vs2019\Angband.vcxproj :

Code:

SOUND;USE_PRIVATE_PATHS;WIN32;_WINDOWS;_CRT_SECURE_NO_WARNINGS;_DEBUG;_CONSOLE;

...Oh heck, I didn't even realize that ANSI was required. That was it!
I just set the character set project option to multi byte from unicode and that seemed to fix the exe.

Thank you!
