Xcode 6 beta 6: Inscrutable Error when analyzing sqlite3.c
| Originator: | jerrykrinock | ||
| Number: | rdar://18115632 | Date Originated: | 2014-08-24 |
| Status: | Open | Resolved: | |
| Product: | Xcode 6 Beta 6 | Product Version: | Xcode 6.0 (6A280e) |
| Classification: | Serious Bug | Reproducible: | Always |
* SUMMARY
I build sqlite3 from source into a static library to ship in my app. For historical reasons, it is built in a separate project. Due to known incompatibilities with Dr. Hipp's coding style and clang, I have set a compiler flag -w -Xanalyzer -analyzer-disable-checker on the amalgamated source file, sqlite3.c.
If I open this project in Xcode 5 and run the static analyzer, it succeeds with no errors. However, when I do the same thing in Xcode 6 Beta 6, I get a these two completely inscrutable errors:
error: error reading 'pic'
error: no analyzer checkers are associated with '-mrelocation-model'
* STEPS TO REPRODUCE
1. Download archive of project folder from here:
http://sheepsystems.com/engineering/sqlite3.zip
2. Unzip, find the project inside and open with Xcode 5.
3. Click in the menu: Product > Analyze. It results in no errors or warnings.
4. Quit Xcode 5.
5. Open the project in Xcode 6 Beta 6.
6. Click in the menu: Product > Analyze.
* EXPECTED RESULTS
No warnings or errors, same as with Xcode 5
* ACTUAL RESULTS

I filed a duplicate for this and got a response, telling me to use -Xanalyzer -analyzer-disable-all-checks which was introduced with Xcode 6.1 (Build 6A1052d) instead of "-w -Xanalyzer -analyzer-disable-checker".
'pic' stands for Position Independent Code. I found it by googling; no idea what it means.

Workaround, sort of
In Build Phases for the sqlite target, Compile, sqlite3.c, if you remove the compiler flag "-w -Xanalyzer -analyzer-disable-checker", then you don't get the error. But you get several dozen spurious warnings when you Analyze :((
