nimforum mirror - iOS compilation error

Hi all!

First of all, thanks for the wonderful language that Nim is.

I'm trying to compile a static library project using --os:ios flag. The <include header, library> will then be used for mobile iOS app. However, I am getting weird errors:


Error: type mismatch: got <int>
but expected one of:
proc c_malloc(size: csize_t): pointer
  first type mismatch at position: 1
  required type for size: csize_t
  but expression 'sizeof(SysLockObj)' is of type: int

expression: c_malloc(sizeof(SysLockObj))
make: *** [build/nim_status.a] Error 1

Does anyone have any idea what is this about?

Thanks!

 is deprecated and everything was supposed to be moved to _t
 but it looks like that particular call in syslocks.nim hasn't been.

I think the diff could be as simple as

154 -      L = castSysLock

L= castSysLock




and

204 -      cond = castSysCond

cond = castSysCond




but I can't test it, i'm afraid

          I'm getting the same error when using Nim 1.2.6 but not when using Nim 1.0.6:

Did you ever find a workaround/fix?

          Sounds like a possible regression that might be worth looking into and/or reporting on Github

          Hopefully this is now fixed in devel, please let me know if not
