compile error when using [email protected] and [email protected]
For the minimum example of using osdialog and crunchy together by running
nimble c -r -d:osdialogGtk3 test.nim --verbosein a directory with:
# test.nim
import crunchy
import osdialog# test.nimble
version = "0.1.0"
author = "Tilmann Bartsch"
description = "Testing osdialog + crunchy"
license = "MIT"
requires "osdialog == 0.1.2"
requires "crunchy == 0.1.8"the following error message is printed:

SIMD Adler32 does not compile on ARM
As stated in the title, on ARM (e.g. Apple M1 in my case) the SIMD implementation of Adler32 does not compile due to missing bindings for some NEON instructions.
Minimal reproducible example:
import std/strutils, crunchy
echo adler32("test").toHexExpected output:
045D01C1
Actual output:
/Users/edisile/.nimble/pkgs/crunchy-0.1.2/crunchy/adler32_simd.nim(156, 17) Error: undeclared identifier: 'vld1q_lane_u32' candidates (edit distance, scope distance); see '--spellSuggest': (2, 6): 'vst1q_lane_u32' [func declared in /Users/edisile/.nimble/pkgs/nimsimd-1.2.2/nimsimd/neon.nim(115, 6)]

- Pixie is also impacted by this issue, when compiling the following code the same error is triggered.
import pixie echo readImage("test.bmp")

Hi Guzba,
i've benchmarked the sha256 agains
nimcrypto and the openssl implementation:
import crunchy, benchy, strutils
let data = "The quick brown fox jumps over the lazy dog".repeat(10_000_000)
echo data.len.formatSize()
timeIt "crunchy sha256":
keep crunchy.sha256(data)
import nimcrypto
timeIt "nimcrypto sha256":
keep nimcrypto.sha256.digest(data)
import strutils
const SHA256Len = 32
proc SHA256(d: cstring, n: culong, md: cstring = nil): cstring {.cdecl, importc.}
proc SHA256(s: string): string =
result = ""
let s = SHA256(s.cstring, s.len.culong)
for i in 0 ..< SHA256Len:
result.add s[i].BiggestInt.toHex(2).toLower
timeIt "openssl sha256":
keep SHA256(data)i compile with:
nim c -d:ssl --passl:-lcrypto --passl:-lssl -d:release -d:allowSimd --gc:arc --opt:speed -d:lto -r "c:\Users\david\projects\nimPlayground\crunchyt.nim"
