iOS Question Build Failed in Local Mac Builder

[Steve Kwok]

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:

Error: ** BUILD FAILED **


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

The B4i Code is for testing iMaplist use:

Private Sub Application_Start (Nav As NavigationController)
    'SetDebugAutoFlushLogs(True) 'Uncomment if program crashes before all logs are printed.
    NavControl = Nav
    Page1.Initialize("Page1")
    Page1.Title = "Page 1"
    Page1.RootPanel.Color = Colors.White
    'Page1.RootPanel.LoadLayout("main.bil")
    NavControl.ShowPage(Page1)
    Msgbox("B4i Hello World!!!", "Say Hi")
    Dim iLst As MapList
    iLst.Initialize
    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.

ld: symbol(s) not found for architecture x86_64

This means that there is no simulator binary in this library.

1. I recommend library developers to use b4xlibs. They are simpler to create and are more robust.

2. Use B4XOrderedMap from B4XCollections: https://www.b4x.com/android/forum/threads/b4x-b4xcollections-more-collections.101071/#content

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.
