Itlwm: how to compile the kext ?

[xrokz]

When i hit build in Xcode i got the build successes but i cant open the kext folder with Show in Finder option i dont know how to get the kexts.

any help ?

[schspa]

I'm newbie too. And I found the builded kexts is at the folder
"/Users/schspa/Library/Developer/Xcode/DerivedData/itlwm-giwpqyjdwchuroetixtxfftvvruv/Build/Products/Release"

[igorkulman]

run

xcodebuild -project itlwm.xcodeproj -target itlwm -configuration Release

and the kext will be build and located in ./build/Release/

Change the SDK version in the project from 10.12 to the version of macOS you are using. Or just delete this line https://github.com/zxystd/itlwm/blob/master/itlwm.xcodeproj/project.pbxproj#L1307

Thanks a lot

Hi @zxystd can we kindly ask you to change your file itlwm.xcodeproj/project.pbxproj and replace inside the 3 instances of:

SDKROOT = macosx10.12;
to
SDKROOT = macosx;

...so that we won't need to touch each time the same file, when updating from your commits?

I did that manually and it compiled great on Mojave 10.14.6 with Xcode 9.4.1 with the command provided in an earlier comment by @igorkulman above:

xcodebuild -project itlwm.xcodeproj -target itlwm -configuration Release

Remains to see if _that_ kext result works on my NUC! Many thanks.

I have an update bash script that saves this change to git stash, pulls the latest code, applies the stash and builds the kext.

[mackonsti]

Thanks @igorkulman but just modifying SDKROOT does not build a working kext on my Mojave with Xcode 9.4.1 in Terminal via the xcodebuild command. The resulting kext that is built without errors cannot get loaded, I get some error due to missing data in Info.plist (I see it's missing CFBundlePackageType key):

Defaulting to kernel file '/System/Library/Kernels/kernel'
Can't record kext in identifier lookup dictionary; no identifier.
Can't record kext in identifier lookup dictionary; no identifier.

Can you nevertheless point us to your bash script, please? Thanks...

Are you guys aware if Xcode > 9 is needed to successfully build this project? Is Mojave compatibility a pain to add?

This is my complete update.sh script that builds the kext on Catalina using Xcode 11.5:

#!/bin/bash

# remove all local changes
git reset --hard HEAD
rm -rf build

# pull latest code
git pull

# remove generated firmware
rm itlwm/FwBinary.cpp

# remove firmware for other wifi cards - DELETE OR CHANGE TO YOUR CARD
find itlwm/firmware/ -type f ! -name 'iwm-7260-*' -delete

# set version as commit count
version=`git rev-list HEAD | wc -l | tr -d ' '`
/usr/libexec/PlistBuddy itlwm/Info.plist -c "Set :CFBundleShortVersionString $version"
/usr/libexec/PlistBuddy itlwm/Info.plist -c "Set :CFBundleVersion $version"

# add my networks - CHANGE TO YOUR NETWORKS
/usr/libexec/PlistBuddy itlwm/Info.plist -c "Set :IOKitPersonalities:itlwm:WiFiConfig:WiFi_1:ssid X"
/usr/libexec/PlistBuddy itlwm/Info.plist -c "Set :IOKitPersonalities:itlwm:WiFiConfig:WiFi_1:password XXX"

/usr/libexec/PlistBuddy itlwm/Info.plist -c "Set :IOKitPersonalities:itlwm:WiFiConfig:WiFi_2:ssid Y"
/usr/libexec/PlistBuddy itlwm/Info.plist -c "Set :IOKitPersonalities:itlwm:WiFiConfig:WiFi_2:password YYY"

/usr/libexec/PlistBuddy itlwm/Info.plist -c "Set :IOKitPersonalities:itlwm:WiFiConfig:WiFi_3:ssid Z"
/usr/libexec/PlistBuddy itlwm/Info.plist -c "Set :IOKitPersonalities:itlwm:WiFiConfig:WiFi_3:password ZZZ"

# remove unused network
/usr/libexec/PlistBuddy itlwm/Info.plist -c 'Delete :IOKitPersonalities:itlwm:WiFiConfig:WiFi_4'

# generate firmware
xcodebuild -project itlwm.xcodeproj -target fwgen -configuration Release -sdk macosx10.15

# build the kext
xcodebuild -project itlwm.xcodeproj -target itlwm -configuration Release -sdk macosx10.15

Just beware that I remove firmware that is not for my AC 7260 to reduce the size (2 MB vs 16 MB when built with everything)

Thanks Guys i will close it i forgot it open,
seems that there is people got good help here

I've updated this script for anyone that comes across this as I did when I had the same issue. I've adapted all the changes that happened over time.

#!/bin/bash

# remove all local changes
git reset --hard HEAD
rm -rf build

# pull latest code
git pull

# remove generated firmware
rm include/FwBinary.cpp

# remove firmware for other wifi cards - DELETE OR CHANGE TO YOUR CARD
find itlwm/firmware/ -type f ! -name 'iwm-7265-*' -delete


# generate firmware
xcodebuild -project itlwm.xcodeproj -target fw_gen -configuration Release -sdk macosx

# build the kexts
## 1. itlwm.kext
xcodebuild -project itlwm.xcodeproj -target itlwm -configuration Release -sdk macosx

## 2. AirportItlwm Catalina
xcodebuild -project itlwm.xcodeproj -target AirportItlwm-Mojave -configuration Release -sdk macosx

## 3. AirportItlwm Catalina
xcodebuild -project itlwm.xcodeproj -target AirportItlwm-Catalina -configuration Release -sdk macosx

## 4. AirportItlwm Big Sur
xcodebuild -project itlwm.xcodeproj -target AirportItlwm-Big\ Sur -configuration Release -sdk macosx

# Location of Kexts
echo "You kexts are in build/Release!!"
echo " "

Remember to change the wifi firmware part to yours or completely delete it to compile with all the firmwares.
