Summary0014064: Xcode generator creating incorrect relative paths
DescriptionThis came up in an Xcode project generated by CMake.
Basic problem looks like this:


eno:quack dave$ /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool -static -arch_only x86_64 -syslibroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk -L/tmp/tst/build/quack/lib/Debug/quack -filelist /tmp/tst/build/quack/runtime/Quack.build/Debug/quack_runtime.build/Objects-normal/x86_64/quack_runtime.LinkFileList /tmp/tst/src/quack/../../build/quack/loon/Hoot.o -o /tmp/tst/build/quack/lib/Debug/quack/libquack_runtime.a
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: can't open file: /tmp/tst/src/quack/../../build/quack/loon/Hoot.o (No such file or directory)
eno:quack dave$ /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool -static -arch_only x86_64 -syslibroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk -L/tmp/tst/build/quack/lib/Debug/quack -filelist /tmp/tst/build/quack/runtime/Quack.build/Debug/quack_runtime.build/Objects-normal/x86_64/quack_runtime.LinkFileList /tmp/tst/build/quack/loon/Hoot.o -o /tmp/tst/build/quack/lib/Debug/quack/libquack_runtime.a
eno:quack dave$


The problem here is that /tmp/tst/src/quack/ is a symlink to /tmp/quack. Therefore, the path traversal of /tmp/tst/src/quack/../../build leads to /build, which doesn't exist.

CMake generated this relative path as far as I can tell; “../..” doesn’t appear anywhere in my CMakeLists or my cmake command The Ninja generator works fine.
Steps To ReproduceSorry I don’t have a small reproducer for you.

Please attach the generated *.xcodeproj/project.pbxproj file.

Sorry, I can’t. It contains information that my employer wouldn’t want me to distribute. I could try to answer some questions about it, perhaps.

Re 0014064:0032778: Okay, does project.pbxproj have any "../.." in it?

Sorry, it's been to long; that project is long gone. How did I only get a notice about the posting from April 8th yesterday?! Email works in strange ways.

Okay. I'm resolving as "suspended" for now.

I don't know why you didn't get notification about 0014064:0032779 but you got the recent notification because the status was changed to request feedback.
