QUESTION
I am trying to integrate OCLint 0.13 to check lint violations in my ObjC based iOS project.
As per this guide I created an aggregate target in Xcode to run a xcodebuild clean build
followed by oclint-xcodebuild
to generate a compile_commands.json
. I am able to run the clang
command from the generated compile_commands.json
file. However, in html report generated by oclint-json-compilation-database
command, while processing file like NEORepos/Public/ResourceObservables/NEOAggregatedObservable.h
, I see compiler errors like 'NEOObservables/NEOObservable.h' file not found
even though the said header file is present at NEOObservables/Public/Observables/NEOObservable.h
.
How can I get rid of these compiler errors which are preventing some of my source files from being linted?
Running the clang command from compile_commands.json
generates the .o
file, but OCLint doesn't seem to be able to compile using the json file.
I also tried adding a few more -I
include paths, but it didn't help. All suggestions and pointers are welcome.
Here's a piece of (edited) log...

ANSWER
Answered 2018-Mar-02 at 19:00The compiler error was due to the -dry-run
flag that I was using. Since it was doing a dry run, it was not creating .hmap
files that were needed (at least not in the right location) leading to .h file not found
errors.
However, without -dry-run
I would have to do a full build which is not acceptable for me. Will update if I find a solution with optimal performance.
