Have you resolved the issue?

Have you resolved the issue?

No, it keeps occuring in our school cluster and the workstation.

You can fix this issue by deleting the line: "namespace DU = DataUtil;", then replacing "DU" with "MotionCor2::DataUtil" in each of those files.
Or you can try this fork: https://drive.google.com/file/d/17s6pbV4nx3emlUnfCuWehYqYtVYitfOq/view?usp=sharing

i just run into the same error with CentOS7 and gcc 4.8.5. The problem is solved when using (in my case) gcc11 and cuda12.

Thanks this worked.

@nym4432018: My apology for this bug. In Correct/CCorrectInc.h, please try by moving "namespace DU = DataUtil;" to above namespace since DataUtil is subspace of MotionCor2, not Correct.

namespace MotionCor2
{ namespace DU = DataUtil;
namespace Correct
{....
}
}

namespace MotionCor2 { namespace DU = DataUtil; namespace Correct {.... } }

Hi, I had the same error as this issue, and followed what you suggested here (correcting the CCorrectInc.h file). Then I got following errors:

@nym4432018: This is a bug in CMainInc.h. Please replace "namespace DU = MotionCor2::DataUtil;" with "namespace DU = DataUtil;"

I am wondering my compiler (g++ (GCC) 8.5.0 20210514 (Red Hat 8.5.0-18)) cannot catch this error. Can you please let me know what g++ version you use? You can run "g++ --version". Thanks.

@szhengczii:
I have observed a related compiling issue when I use the devtoolset_7 on CentOS 7. The error message is listed below for your reference.

However, when I switched to devtoolset_8 or devtoolset_9, the compiling error is gone and the compiled MotionCor3 is functional. Thus, it appears this is a compiler dependent bug.
