iOS Question Build Failed in Local Mac Builder

Hi, everyone,

my B4i project found build failed in my local mac builder since it contains iMapList Library.

I had downloaded 3 files:
  • iMapList.h
  • iMapList.xml
  • libiMapList.a
from iMapList - combining a Map and a List
and put the them to Macbook under /B4iBuildServer/Libs/

The error message shown as:


The last few lines shown as:
local mac build error:

Error: ** BUILD FAILED **

The following build commands failed:
    Ld /Users/support/B4iBuildServer2/UploadedProjects/<user id>/Payload/hk\ B4i\\ B4i\ Example normal x86_64
(1 failure)

The B4i Code is for testing iMaplist use:
test iMaplist library:
Private Sub Application_Start (Nav As NavigationController)
    'SetDebugAutoFlushLogs(True) 'Uncomment if program crashes before all logs are printed.
    NavControl = Nav
    Page1.Title = "Page 1"
    Page1.RootPanel.Color = Colors.White
    Msgbox("B4i Hello World!!!", "Say Hi")
    Dim iLst As MapList
    iLst.Add("1", "Apple")
End Sub

It seems the build error comes from iMapList library files but I have no idea how to solve this problem.

Dear Erel,

Thank you for your promptly reply.

My workaround is:
  1. replacing iMapList (Version: 2.01) library by B4XCollections (Version: 1.05) library.
  2. declare custom Type called typField(storeid as String, trx As Double) and declare a list lstStore as collector.
  3. make use of lstStore.SortType("storeid", <True/False>) and lstStore.SortType("trx", <True/False>) to sort by field(s).
As I expected, my app can be successfully built by local mac build server.
