Discussion Overview

The discussion revolves around issues encountered while trying to build the VTK project in Xcode and via MacPorts. Participants are exploring the causes of build failures, errors related to project file parsing, and undefined symbols during compilation.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant reports an error indicating that the VTK.xcodeproj file cannot be parsed, with the first line containing an unexpected character.
  • Another participant suggests that the error may stem from the system attempting to execute the project file as a script, implying a missing program necessary for loading it.
  • Concerns are raised about the adequacy of installation instructions, which are described as unhelpful and lacking detail on configuration steps.
  • A participant mentions trying to install VTK via MacPorts but encounters errors related to undefined symbols during the build process, indicating potential issues with dependencies or configuration.
  • There are repeated questions about whether the VTK.xcodeproj file can be opened in Xcode and whether there are references to it in the Makefile.
  • One participant expresses frustration with the build process and considers reinstalling everything from scratch as a last resort.
  • Several participants inquire about the status of Xcode and whether other projects can be built successfully, seeking to clarify the environment setup.
  • Errors related to specific files in the VXL dependency are also highlighted, indicating further complications in the build process.

Areas of Agreement / Disagreement

Participants express a range of views on the causes of the errors, with no consensus reached on the specific issues or solutions. Multiple competing perspectives on troubleshooting and installation approaches are present.

Contextual Notes

Participants note that the installation instructions lack clarity, and there are unresolved questions about the configuration process and dependencies that may affect the build. Specific errors related to undefined symbols and parsing issues remain unaddressed.

I'm trying to build code in Xcode, but I keep getting the following error:

Code: 
xcodebuild[17565:903] Unexpected character / at line 1
xcodebuild: error: Unable to read project 'VTK.xcodeproj'.
Reason: Project ../VTK.xcodeproj cannot be opened because the project file cannot be parsed.

make: *** [../VTK-build] Error 74
Command /bin/sh failed with exit code 2

I tried to edit the file causing the error, but I can't see what's wrong with it. Line 1 says: // !$*UTF8*$!

Does anyone have a clue what could be the cause?
 
Technology news on Phys.org
The error means that the system tries to execute the file VTK.xcodeproj as if it is a script file, but it isn't.
It's a project file that should be loaded by some program.
I suspect it means that you are missing a program on your system.

In the file named "Makefile" there should be a line somewhere with the text "VTK.xcodeproj".
It should have something in front of it that is the program to be used to load it.
That may give a hint of what you're missing.

Anyway, you can probably solve it by reading some of the installation instructions.
 
Shouldn't VTK.xcodeproj be able to open in Xcode? I have other .xcodeproj files that do.

The installation instructions are not very helpful. It says to configure and generate the superbuild files in cmake and then make the files with "make -j9". That's it
 
I tried an alternate approach, install via macports. Here I also get an error and again something about undefined symbols? Other software installs just fine, this is annoying.

Did you try to open VTK.xcodeproj with Xcode?
Can you find a reference in the Makefile to VTK.xcodeproj?


The installation instructions are not very helpful. It says to configure and generate the superbuild files in cmake and then make the files with "make -j9". That's it

Did you carefully monitor the build process and check for warnings or errors?
You say "configure", so did you configure anything?
 
I like Serena said:

Yes, I get a parse error.
Can you find a reference in the Makefile to VTK.xcodeproj?
no, I don't

Did you carefully monitor the build process and check for warnings or errors?
Yes, I posted it in the first post and again in the later post with the other approach.
You say "configure", so did you configure anything?
I used default settings to generate the build files.

I tried installing another dependency VXL and that fails as well. I'm starting to think the only solution is to wipe my computer clean and install everything from scratch :( which I don't want to do.
 
Let me see if I understand the situation correctly.

Do you have a working Xcode?
Are you programming in Xcode for that matter?
Can you build other projects?

What kind of project is VTK?
Is it a project you downloaded and are building from source?

You said you tried to edit the file causing the error.
Which file did you mean?

yes, yes, yes.

vtk.org, yes

Which file did you mean?
VTK.xcodeproj, the file that can not be parsed.

Here is the part of the building process that gives errors and causes the premature abortion of make:

Do these compilation errors occur before the error you had on the unexpected '/'?

What does line 107 say in the following file?
/ExternalProjects/Source/VXL/core/vil/file_formats/vil_openjpeg.cxx

I like Serena said:

These compilation errors I get when I perform make in my terminal window. Sorry, I did not use Xcode in this attempt because I'm trying different things to get to the bottom of it (:smile:) So, the compilation errors in my previous post are the first that I encounter in that attempt.

What does line 107 say in the following file?
/ExternalProjects/Source/VXL/core/vil/file_formats/vil_openjpeg.cxx
It says:
opj_codec_t *codec_;

Thanks so much for thinking along, I never encountered problems before that I couldn't solve.

opj_codec_t *codec_;

That would suggest that the type opj_codec_t is unknown.
Since it would have been defined in an earlier include, that suggests a versioning problem.
It seems it should have been defined as part of the openjpeg library (openjpeg.h), which contains similar definitions.
Can you trace where opj_codec_t should come from?
Perhaps a "grep" on the openjpeg include files?

Thanks so much for thinking along, I never encountered problems before that I couldn't solve.

Welcome to the club. :smile:
