Using Nim stable and tried it on devel, windows x64.
So running a simple main or the samples I get the following error:

λ nim c samples.nim

..\..\..\..\.nimble\pkgs\libtcod_nim-0.99\src170\parser.nim(117, 5) Error: expected closing ')'

Looking at the line there doesn't seem to be anything wrong with it though.
EDIT: removing the comment made it compile even though nim check threw a bunch of errors at me.

How would one go about adding support for 1.6.x?
https://libtcod.readthedocs.io/en/latest/upgrading.html
As far as I know 1.5.1 works well enough for most cases, so upgrading might not be even worth it.

If I have the following project structure:
-- data/font.png
-- src/main.nim ( and related dll's)
--out/main.exe

and in my main.nim a const set as

const font = "../data/font.png"

I get the following error when running the main binary :
SDL : cannot load ../data/font.png

However putting the main.exe and dll's in the src folder and then running the executable it works perfectly fine.
Not a big thing and maybe even my fault, but is this something known? Googling get's me an answer saying it should be in the same folder as your source files.

This command:

./build_samples

results in this error:

/home/david/.nimble/pkgs/sdl1-1.0.0/sdl.nim(1064, 27) Error: undeclared identifier: 'expr'

Getting this error when trying to compile on Windows.

I got this error when compiling the samples in the latest Nim version 1.2.2:

C:\...\samples112\samples.nim(1489, 31) Error: type mismatch: got <tuple of (string, proc (first: bool, key: ptr Key, mouse: ptr Mouse){.cdecl, locks: <unknown>.})> but expected 'tuple of (string, proc (first: bool, key: ptr Key, mouse: ptr Mouse){.cdecl, gcsafe, locks: 0.})'

To make it work I added the gcsafe pragma to this line:

But it throws this warning, though:

C:\...\libtcod_nim\samples112\samples.nim(1145, 6) Warning: 'renderName' is not GC-safe as it accesses 'names' which is a global using GC'ed memory [GcUnsafe2]

By the way, there's also this warning lying around there:

C:\...\.nimble\pkgs\libtcod_nim-1.112.0\src112\sys.nim(161, 53) Warning: use `csize_t` instead; csize is deprecated [Deprecated]

I've been using these bindings, but they're quite outdated for some time now. There are some more recent features that I'd love to be using.

Sadly I don't have the knowledge to do this myself and help you out with a pull request...

When running build_samples.sh, I first get this error:

samples.nim(7, 8) Error: cannot open file: libtcod

I need to work around that by editing samples.nim line 7, and changing this line:

import libtcod, os, parseutils, math

To this:

import ../libtcod, os, parseutils, math

My next problem after that is this error:

../libtcod_nim/private/console.nim(163, 14) Error: usage of 'isNil' is a user-defined error

Which I can work around by adding a sample.nims file with these contents:

--nilseqs:on

After which, the 'samples' binary compiles and runs fine.

The samples work fine so I'm not sure why this small snippet isn't working:

when isMainModule:
  consoleSetCustomFont(font, FONT_LAYOUT_ASCII_INROW)
  consoleInitRoot(ScreenWidth, ScreenHeight, "Demo", false, renderer)
  while not consoleIsWindowClosed():
    consoleSetDefaultForeground(nil, WHITE)
    consolePutChar(nil, 1, 1, '@', BKGND_NONE)
    consoleFlush()
    discard sysCheckForEvent((EVENT_KEY_PRESS.ord or EVENT_MOUSE.ord), addr(key), addr(mouse))
    if key.vk == K_ESCAPE: break
  libtcod.quit()

renderer is set to RENDERER_SDL2 and I get the following error:

Traceback (most recent call last)
C:\Users\rishiPC\stack\dev\gamedev\ndtrl\src\main.nim(15) main
SIGSEGV: Illegal storage access. (Attempt to read from nil?)

line 15 being the consoleInitRoot call.

When running the samples (112), when I select the name generator something goes out of bounds:

main.nim(1607)           main
main.nim(1169)           renderName
system.nim(2918)         sysFatal
Error: unhandled exception: index out of bounds [IndexError]

(I'm not running the samples along with the repo, though, I just copied the code from samples.nim into a file, placed the fonts in data/fonts next to it, changed the DATA_PATH const in the code from "../data/" to "./data/" and compiled it. Not sure if any of that makes a difference.)

I've tried running it a few more times and it's happening every time I select the name generator, but just a few minutes ago I was able to select it for some reason, and it was throwing this into the console repeatedly:

Registered syllable sets are:
The name "" has not been found.

I never tried libtcod samples before, so I don't know what the normal behavior for the name generator is, but I found it odd that when I pressed + and - it showed something like ===== (iirc, or maybe it was """"""") on the screen. I supposed it should be showing generated names.

Trying to run a very basic project:

Traceback (most recent call last)
wizx_roguelike.nim(54)   wizx_roguelike
wizx_roguelike.nim(23)   handle_keys
SIGSEGV: Illegal storage access. (Attempt to read from nil?)

Have attached wizx_roguelike.nim for reference.

Renamed to .nim.txt, since github doesn't like uploading of .nim files.
