Bug 259527 – When using build-jsc on Linux: Can't exec "xcodebuild": No such file or directory

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Michael Catanzaro]

We have a (seemingly harmless) warning that prints when using build-jsc on Linux:

$ build-jsc --jsc-only --debug --cmakeargs='-DENABLE_C_LOOP=ON -DENABLE_JIT=OFF -DENABLE_SAMPLING_PROFILER=OFF'
Can't exec "xcodebuild": No such file or directory at /home/mcatanzaro/Projects/WebKit/Tools/Scripts/webkitdirs.pm line 355.
Use of uninitialized value $xcodebuildVersionOutput in pattern match (m//) at /home/mcatanzaro/Projects/WebKit/Tools/Scripts/webkitdirs.pm line 356.

A stack trace would help here - line 355 is in a function that shouldn't be called on Linux at all.

Stealing the solution to print a stack trace from https://stackoverflow.com/a/13088008/1120203, I found:

Stack Trace:
/home/mcatanzaro/Projects/WebKit/Tools/Scripts/webkitdirs.pm:1253 in function webkitdirs::xcodeVersion
/home/mcatanzaro/Projects/WebKit/Tools/Scripts/webkitperl/BuildSubproject.pm:150 in function webkitdirs::XcodeOptions
/home/mcatanzaro/Projects/WebKit/Tools/Scripts/build-jsc:33 in function (eval)
/home/mcatanzaro/Projects/WebKit/Tools/Scripts/build-jsc:33 in function main::BEGIN
/home/mcatanzaro/Projects/WebKit/Tools/Scripts/build-jsc:33 in function (eval)

I think we can fix this by just moving the calling code into an XCode-specific path.
