I have a library in source code, it builds in .a static library, but i need .dylib. So, i choose Mach-O-Type in "Build Settings" as "Dynamic Library", but get error:

libtool for some reason uses "-static" instead "-dynamic" flag... Compatibility version i've set. What do you think could be wrong?
object files (.o) could be extracted from archive file (.a) and then packed in .dylib with libtool or gcc

I remember in old Xcode there was option under Create New Project there was option to create BSD Dynamic Library - dylib. However now I see only Cocoa Framework, Static Library and Metal Library.
Any hints?
You may create a project for an iOS static lib, and create a dynamic lib from the static one with a custom build phase with the following command:
xcrun --sdk iphoneos clang -arch <ARCH> -shared -all_load \
-o lib<NAME>.dylib lib<NAME>.a
where <ARCH> is either armv7 or arm64 and <NAME>is the base name of your lib. You may check or list the architectures with file command. E.g.:
file <path>/lib<NAME>.a`
lib<NAME>.a (for architecture armv7): current ar archive random library
lib<NAME>.a (for architecture arm64): current ar archive random library
If more than one architecture is listed, Xcode has produced a universal static library. In this case you may create a universal shared library with multiple -arch flags:
xcrun --sdk iphoneos clang -arch armv7 -arch arm64 -shared -all_load \
-o lib<NAME>.dylib lib<NAME>.a
You may need to specify additional linker flags (e.g. -l for linking non-standard libs).
i am trying to get my app on testflight for testing. however when following the instruction on this video https://www.youtube.com/watch?v=6tydk4Fc-tg&t=302s everything work up to trying to archive the app.
i get the below error and i'm not quite sure what to do. if you have any idea on how to solve this problem, please help. i'm using Xcode 7.3.1 and ivy 1.9.1.

The error tells you clearly what to do. When you see the dialog that asks if you want to rebuild using bitcode, you must uncheck that option. If you are not even getting that far, use the build settings of your target to disable bitcode:
In that screen shot, you'd need to switch from Yes to No.
I am trying to follow this guide here for building SDL2 for iOS:
http://lazyfoo.net/tutorials/SDL/52_hello_mobile/ios_mac/index.php
I am able to build the libSDL2.a static library, however I am getting a linker error when I attempt to build his example hello world application which uses it.

Per his instructions, I copied the project template and added the libSDL2.a lib that I built under the Build Phases -> link binary with libraries menu:
Any suggestions for how I can debug this problem?

It's likely that the static library you built does not contain the architecture for which you're building your application. You'll need to build a static library that contains the architectures for the platform you want to build.
Also, keep in mind that it's not actually supported to put architectures for different platforms (such as iOS and tvOS, or even iOS and iOS Simulator—the simulators are separate platforms) in a single binary. You'll need a separate library or framework for each platform you're targeting, though each one can of course contain slices for all of that platform's supported architectures.
I have a problem with linking a compiled program (see github repo for details).
The osx specific makefile section is here:
CFLAGS = -v -arch x86_64 -Wall -fPIC -O2 -I./include $(OPTS)
LDFLAGS = -v -arch x86_64 -lpthread /usr/local/lib/libportaudio.a -framework CoreAudio -framework AudioToolbox -framework AudioUnit -framework Carbon
EXECUTABLE ?= squeezelite-osx
include Makefile
The compilation works fine, but during the linking it fails with:

The library which is not found is in the folder /usr/local/include and I think I have to add this path to the include path of the linker.
How can I add the path /usr/local/include to the include path of the linker?
The linker doesn't use include files; that's the compiler (actually the pre-processor, but let's keep it simple).
Instead you need to tell the linker that it should look in /usr/local/lib using the -L option:
-L/usr/local/lib
Note: you can provide more than one -L option to the linker.
I have used CMake 3.3.0-rc4 to generate an Xcode project for OpenTrack. However, when I attempt to build the ALL_BUILD target in Xcode 6.4, I immediately get the error below.

The Build Settings for the project has the following set for Linking / Other Librarian Flags:
OTHER_LIBTOOLFLAGS = -stdlib=libc++ -framework Cocoa -framework CoreFoundation -lobjc -lz -framework Carbon
From the libtool usage statement above, it looks to me like this set of options was generated for an entirely different version of libtool. What can I do (if anything) to get this project to build with the current version of Xcode?
You cannot use the flag -stdlib=libc++ or -framework with libtool, as they are valid only in the linker, so you should make OTHER_LIBTOOLFLAGS empty as none of those options apply
