Re: [Oorexx-devel] Need some help with linux debugging.

I made a debug on MacOs with Xcode (after fixing the compile error).

Then during further investigation, I noticed other things to fix (probably already fixed locally in your sandbox)

FileNameBuffer.hpp :

replace memcmp by memcpy where appropriate (2 occurrences)

unix/SysInterpreterInstance.hpp :

replace ‘;’ by ‘:’ where appropriate (2 occurrences)

After fixing that and adding the copy constructor & operator, I was able to build your sandbox, and the resulting rexx executable is working.

To check if the copy constructor & operator is really needed, you can declare them private.

You will have some compilation errors, it’s a good way to see where the compiler creates temporary objects for FileNameBuffer

Unfortunately I get

/opt/oorexx.rick/interpreter/platform/unix/SysRexxUtil.cpp: In function '_RexxObjectPtr* SysGetFileDateTime_impl(RexxCallContext*, CSTRING, CSTRING)':
/opt/oorexx.rick/interpreter/platform/unix/SysRexxUtil.cpp:1693:102: error: 'echoOpt' was not declared in this scope
invalidOptionException(context, "SysGetFileDateTime", "time selector", "'A' or 'W'", echoOpt);

For my rexxutil sandbox version, I'm able to get a clean build on Windows, but on Linux, I get a crash running rexximage. I've tried debugging this using ddd, but it doesn't really give my any useful information. I'd really appreciate any assistance you can provide.
