I'm currently working with Objection.h and an Open Source project called Linklyy, and I'm getting the following linker error:

ld: 40 duplicate symbols for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I see that the architecture should be changed based on the warning, but there is also a linker error present. Can anyone help me figure out the cause of the inker error? I'm sure that it is something related to Objection.h. Please, don't hesitate to ask for more information if necessary.
Check targets for the JSObjection. It's look like the JSObjection included in the App target and a Pods target at the same time. It is also possible that libJSObjection.a is linked with the Pods and with the main App.

I aware there are similar questions on here but the answers given are not helping me. So here's my questions specifically.
So Upgrading from 0.57.8 to 0.58.x seems to give me this issue:
ld: 32 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
My podfile already has solutions recommended on other questions:

ld: 32 duplicate symbols for architecture x86_64

Assuming that the project is on Git, Rename the current folder (for example if it is "MyProject", change it to "MyProjectt"), then:
Commit all your changes!
Create a new project with that name react-native init MyProject --version=0.58.9
Copy the .git folder (note that it's hidden) - also copy all your .js files such as app.js and package.json
Install all your dependencies and bump up the react-native version too!
Run your Git client (for example GitHub desktop) - you see changes in iOS and android folder
Commit changes
I get the following error from the linker 'ld' during linking.
ld: 0711-302 ERROR: Object SomeLibrary.a[SomeObject.o], csect <.text>
The csect is part of the .text section, and relocation entries
from the csect have been written to the .loader section.
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
What does this error mean?
(BTW I am using GCC for AIX)
I'm trying to build a simple command line application which uses WinUSB in Visual Studio 2013. I'm getting no compile errors, but lots of linker errors. The following are some of them:
winusblnk.obj : error LNK2019: unresolved external symbol imp__Sleep#4 referenced in function _msDelay
winusbnet.obj : error LNK2001: unresolved external symbol __imp__Sleep#4
What do the references to obj files mean? How do I see these OBJ files? How can I inspect them and see what functions they have inside them?
What does __imp__Sleep#4 mean? What do all the underscores mean? What does the #4 mean? How do I find the reference to this symbol?
What is the difference between error LNK2019 and error LINK2001?
There are lots more similar errors in winusbxxx.obj files.
errhnd.obj : error LNK2019: unresolved external symbol __imp__GetLocalTime#4 referenced in function _logerr
readtemp.obj : error LNK2019: unresolved external symbol _ReadTemperature referenced in function _main
Same questions.
MSVCRTD.lib(gs_report.obj) : error LNK2019: unresolved external symbol __imp__IsDebuggerPresent#0 referenced in function ___raise_securityfailure
MSVCRTD.lib(error.obj) : error LNK2001: unresolved external symbol __imp__IsDebuggerPresent#0
How do I look at the contents of these lib files, and see which obj files they contain, and which functions each of those contain?
There are lots more errors in MSVCRTD.lib
I hope someone can give me some guidance on finding the cause of all these errors.
Thanks - Rowan
I have a problem with linking a program, the strange thing about that is that functions that linker can't resolve, sit in the same file near the functions that are resolved without a problem.
I can't post files themselves in the message as they are pretty large, though ===> here <=== is the project ready to be built.
Here are build errors:
error LNK2019: unresolved external symbol _leveldb_filterpolicy_destroy referenced in function _main
error LNK2019: unresolved external symbol _leveldb_options_set_filter_policy referenced in function _main
error LNK2019: unresolved external symbol _leveldb_filterpolicy_create_bloom referenced in function _main
error LNK2019: unresolved external symbol _leveldb_filterpolicy_create referenced in function _main
error LNK2019: unresolved external symbol _leveldb_filterpolicy_create referenced in function _main
Here is the full-size screenshot showing error messages
Here is the implementation of the function that cant be found:
Here is the implementation of the function that sits in the same file and is easily found by the linker:
I've found-out what was causing the problem, I've updated the version of leveldb to a newer one. The newer version introduced several new functions (the ones that are being unresolved). But I haven't updated the .def file which contains all exports, and functions weren't exported as a result...
My code is identical to this question I asked earlier so there's no point in duplicating it here
This is the error I am getting:
Undefined symbols for architecture x86_64:
"_stdscr", referenced from:
_screen_init in screen.o
"_werase", referenced from:
_screen_init in screen.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I've had this error in the past and I feel like it has something to do with a duplicate function name or something, but I have no idea how to debug this.
EDIT:
After adding the libncurses.dylib file to my project, the errors discussed above have disappeared, but a new error has emerged when I call screen_init(); in my main.cpp:
// main.cpp
#include "screen.h"
int main(){
screen_init();
}
// new error
Undefined symbols for architecture x86_64:
"screen_init()", referenced from:
_main in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Pretty much the same error except now in my main. Is there another library I am missing? These errors are very mysterious and not very helpful.
I guess you need to add the library to your link phase, if you are going with XCode you should add it in project details:
choose project details
choose build phases tab
open link binary with libraries part
click the plus symbol
add libncurses.dylib to your project.
