Aim
I am trying to build the simplest Theos application that is acting like HTTP server.
I have no specific preferences on what libraries to use, but I tried by best using HTTPKit this time. I will appreciate any comments and/or links on how to build such applications.
Question in a couple of words
Failed to use HTTPKit in Theos application project. Getting "Undefined symbols" when using any of the HTTPKit classes.
Personal thoughts
I am sure the "Undefined symbols" error is caused by wrong linking. And I am almost sure that it has to do something with the dependencies folder since I have no idea where to put it and how to link it.
It's not completely neccessary to use HTTPKit, but I am having quite the same troubles trying to implement CocoaHTTPServer in Theos application.
I will also appreciate any comments on what I am doing wrong while installing Theos and making applications.
How I installed and configured Theos
Installed Theos using the following guide
Downloaded everything from one of the headers repository into
$(THEOS)/include
Downloaded (additionally) IOSurfaceAPI.h from here into
$(THEOS)/include/IOSurface
Making a simple project
1.Created a Theos application using NIC
cd ~
$THEOS/bin/nic.pl
NIC 2.0 - New Instance Creator
------------------------------
[1.] iphone/application
[2.] iphone/library
[3.] iphone/preference_bundle
[4.] iphone/tool
[5.] iphone/tweak
Choose a Template (required): 1
Project Name (required): name
Package Name [com.yourcompany.name]:
Author/Maintainer Name [***]:
Instantiating iphone/application in name/...
Done.
2.Put the whole repository HTTPKit into newly created folder
~/name/HTTPSources
3.Added the following line
name_FILES += $(foreach ext, c cpp m mm x xm xi xmi, $(wildcard
HTTPSources/*.$(ext)))
into the Makefile, so it looks like this
4.Put all files from here into newly created
$THEOS/include/HTTPKit
5.Now the $(THEOS) folder looks like this
6.Calling make now doesnot cause fatal errors (except ldid command, which I guess is not vital) resulting in
~/name/theos/makefiles/targets/Darwin/iphone.mk:41: Deploying to iOS 3.0 while building for 6.0 will generate armv7-only binaries.

/bin/sh: ldid: command not found
Trying to use HTTPKit, getting errors
1.Added HTTPKit import and a few simple lines from the example
HTTPServer * serv = [[HTTPServer alloc] init];
[serv handleGET:#"/hello/*"
with:^(HTTPConnection *connection, NSString *name) {
return [NSString stringWithFormat:#"Hello %#!", name];
}];
into ~/name/main.m so it looks like this
2.Now calling make causes "Undefined symbols for architecture armv7" error
~/name/theos/makefiles/targets/Darwin/iphone.mk:41: Deploying to iOS 3.0 while building for 6.0 will generate armv7-only binaries.
Making all for application name...

Additional info
find ~/name
make clean all messages=yes
Try adding
export ARCHS = armv7 arm64
export TARGET = iphone:clang:7.0:7.0
to your makefile.
That fixed a similar error for me. If the error is different would you be so kind as to post the output?
I think you missing library. You only have HTTPServer header but lack of implement. Compile HTTPKit and put it on $THEOS/lib. Then add name_LIBRARIES = nameoflibHTTKit in Makefile

I want to fuzz the map loading feature in counter strike. The source code for csgo got leaked a while back and here is a build which you can compile https://github.com/SwagSoftware/Kisak-Strike . However, when I try to compile it using this command:
AFL_USE_ASAN=1 PERSIST=1 cmake -DCMAKE_BUILD_TYPE=Debug -DUSE_ROCKETUI=ON -DFREETYPE_LIBRARY=/usr/lib/x86_64-linux-gnu/libfreetype.so -DFREETYPE_INCLUDE_DIRS=/usr/include/freetype2/freetype/ -DUSE_KISAK_PHYSICS=ON -DCMAKE_C_COMPILER=/home/cyberhacker/Asioita/Hakkerointi/Counterstrikestuff/aflpp/afl-gcc-fastthing/AFLplusplus/afl-gcc-fast -DCMAKE_CXX_COMPILER=/home/cyberhacker/Asioita/Hakkerointi/Counterstrikestuff/aflpp/afl-gcc-fastthing/AFLplusplus/afl-g++-fast ..
and then when i try to run ./csgo_linux64 , it throws this error:
Failed to load the launcher(bin/linux64/launcher_client.so) (/home/cyberhacker/Asioita/Csgocompile/withjump/game/bin/linux64/libtier0_client.so: undefined symbol: __afl_area_ptr)
I am expecting it to just work as usual (same as with the regular build). It works completely fine when I try to compile it normally with this command:
cmake -DCMAKE_BUILD_TYPE=Debug -DUSE_ROCKETUI=ON -DFREETYPE_LIBRARY=/usr/lib/x86_64-linux-gnu/libfreetype.so -DFREETYPE_INCLUDE_DIRS=/usr/include/freetype2/freetype/ -DUSE_KISAK_PHYSICS=ON -DCMAKE_C_COMPILER=/usr/bin/cc -DCMAKE_CXX_COMPILER=/usr/bin/c++ ..
and then make -j8
I searched a bit and found this: this . In that conversation they say that this error can be cause by compiling with afl-gcc but then linking with normal gcc or ld. However this is not the cause of my problem since I have looked through the cmake log files and the binaries are being linked with afl-g++-fast so this shouldn't be a problem in my case. I read somewhere that the libraries should be statically included, not dynamic but I do not think that it is a necessity. Feel free to look at the Kisak strike source code if you want to (obviously).
I'm getting this error in all my app builds now and I can't seem to figure it out.
I am using the .xcworkspace file
I had to rename the app. Used: react-native-app-id ...
This morning I was able to build/run on emulator. I tried to setup xcode to run on an actual device and now the universe hates me.
I can't even react-native start and react-native run-ios without getting these errors:
ld: warning: directory not found for option '-L/Users/gmike/Projects/promiscue/tribeoffive/TribeOfFive/ios/build/Build/Products/Debug-iphonesimulator/React'
ld: library not found for -lReact

I've checked out a bunch of other stackoverflow articles.
I think this is telling:
Thoughts on how to un-mess up my env?
The error goes away when you remove libReact.a from the Xcode file tree (for me, it was under the Frameworks folder).
I also removed other files (they all had a transparent/white overlay on them which probably mean they were missing, actually couldn't open them in the finder neither)
Ok let's resolve this:
What to look for:
Here's a list of all the sub projects (or their products) that will cause XCode to throw that error when building a react-native project w/ cocoapods:
[
RCTActionSheet,
ART,
RCTBlob,
RCTCameraRoll,
RCTGeolocation,
RCTImage,
RCTLinking,
RCTAnimation,
RCTNetwork,
RCTPushNotification,
RCTTest,
RCTSettings,
RCTText,
RCTVibration,
RCTWebSocket,
]
Where to look for those weird project names:
First of all you'll look in the actual error message.
Here's a typical library not found error
Notice the ... /libART.a part?
That fellow is causing that error on my end.
In your case it can be any of the strings in the array above.
Found the troublemaker, what to do now?
Step 1: Remove the troublemaker project.
Let's try the lucky shot first:
Open the Project Navigator, and check if you can see the linked project that corresponds to the troublemaker string. In my case it was an XCode project called ART.
If you find it there, just remove it's reference, and you should be fine.
If that didn't work:
Open {Project Target} > Build Phases > Link binary with libraries and check wether you can see the troublemaker string in there. (It could be something like libArt.a depending on what's causing the issue on your end)
If that worked, forget the next step, otherwise move on:
Step 2: Delete the derived data directory, clean and rebuild
In my case (as seen in the raw error above) the derived data directory was /Users/sudoplz/Library/Developer/Xcode/DerivedData/MySuperApp-haxjchilyksewvdfcnnxwrulvyvy/Build/Products/Debug-iphonesimulator/
find yours in the error log, and delete it.
You can then clean XCode, shut it down, launch it again, and re-build.
Hopefully that should either fix the issue, or help you move on with fixing other stuff that may have gone wrong.
That's all folks.
Try to add that file to the libraries by finding libReact.a from the project, then clean and run Xcode.
or
Try to add libReact.a to your project "Build Phases" > Link binary with libraries, then clean and run Xcode.
This is a weird error! I'm getting:
ld: framework not found CocoaFob
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I've checked all my build settings - and they appear correct. CocoaFob.framework is in my Linked Frameworks and Libraries - showing healthy and black. For some reason though, the damned framework isn't found when I try to link. Does anyone have any ideas?
Once possible clue is that when I try to the cocoafob application ( from here: https://github.com/glebd/cocoafob ) I get exactly the same error. I'm using Xcode 8.2.1
Okay. So the solution for me (and hopefully this will help anyone else who's experiencing a similar problem) was to:
build CocoaFob as release (I'd already done this, but in the interests of completeness) copy the resultant built framework to /Library/Frameworks and use it from there.
Do not attempt to use it in the location where it was built! Neither should you create a symlink in /Library/Frameworks to the location where it was built.
This done, all works well. Phew!
Objective: Build a cocoapod with CI support through travis-ci and coveralls.
Sub Objective: Keep git repo cleared of Pods/, while still including Podfile and Podfile.lock
Referenced repo: SRRandomUser
note: while indeed there exists a simple workaround solution (just removing Pod/ from my .gitignore, I ask this question because it will likely be helpful to understand this issue for future work.
Here is the situation I find myself in:
Using FSNetworking for network requests.
One of its classes, FSNData, has a class method withImage:jpegQuality:fileName: that accepts a UIImage and CGFloat as parameters.
Building this file without adding #import for UIKit and CoreGraphics results in a compiler error of expected a type with reference to the UIImage and CGFloat parameters
Locally, this is not a problem because I can add the module #imports, however since I am not committing the entirety of the Pods/ directory, these changes don't get pushed
Travis received the build and attempts to build, but since the FSNData doesn't have CoreGraphics or UIKit imported, when Travis goes to build the project, it throws the error in SRRandomUserGenerator since that class is #importing the affected FSNData class:
✗ Compile SRRandomUserGenerator.m (73 ms)

2 errors generated.
So, my questions are:
How do I either silence that warning so that the build runs anyhow or
How do I get that Pod to include the correct frameworks for building?
Many thanks in advance, SO.
I would recommend trying to search for the framework you need via Cocoapods.org. If you're using Cocoapods it usually means that it's been linked to your project (so there's really no way to silence the error, especially in this case where it seems that the framework you're using depends on other frameworks)
I have software that first loads a .dylib lets call libFirst.dylib using the following command:
void* handle = dlopen(path.c_str(), RTLD_LAZY | RTLD_GLOBAL);
Later on inside a function from the loaded libFirst.dylib I attempt to load another .dylib using the same command but for libSecond.dylib, the loading of this shared library gives me the following warnings in my Xcode console:
error warning: Ignored unknown object module at 0x129310 with type 0x8a8399
dlerror: dlopen(/path/libSecond.dylib, 9): Library not loaded: libFirst.dylib
Referenced from: /path/libSecond.dylib
Reason: image not found
What I don't get is that its says libFirst.dylib is not loaded but I am currently inside a function from libFirst.dylib, so how can this be?
All my paths in DYLD_LIBRARY_PATH appear correct too.
Thanks in advance, I have been stuck on this for days.
I ended up using -install_name to change the install name of all my libraries to #rpath/dylibName.dylib and then in Xcode I set the Runpath Search paths using #loader_path to find all my .dylibs that I was using.
use:
install_name_tool -id #executable_path/../Frameworks/mylib.dylib mylib.dylib
then check it with:
otool -D mylib.dylib
I think an easier way to get around this error would be to revert to an earlier version where you were not getting this error. Right click on the project folder and navigate to local history to revert to an earlier version. I verified this to be working on the android studio installed on Mac OS Big sur.
