Introduction

La curiosité m’a piqué après la lecture de ce post : Hello world

Du coup j’apporte ma contribution avec le language Nim

Tous les tests sont effectués sous :

VoidLinux VoidLinux
- MUSL 1.1.24
- GLIBC 2.30
GCC 9.2.0 GNU GCC
Nim 1.0.4 Nim
UPX 3.95 UPX

Le code source en Nim est des plus simples :

-bash-5.0# cat hello.nim
echo("Hello world")
-bash-5.0#

Test case	Execution time	Total syscalls	Unique syscalls	Size (KiB)
Nim (musl, static)	0.00s real	16	8	34.3 KiB
Nim (musl, dynamic)	0.00s real	18	9	30.6 KiB
Nim (glibc, static)	0.00s real	19	10	713.5 KiB
Nim (glibc, dynamic)	0.00s real	46	14	30.9 KiB
Nim (musl, static, upx)	0.00s real	34	13	17.8 KiB
Nim (glibc, static, upx)	0.00s real	37	14	280.3 KiB
Nim (musl, static, danger, upx)	0.00s real	34	13	15.0 KiB
