Compilation error, tsv-filter: undefined reference

[jondegenhardt]

Hi Boulund,

I don't know why this is happening on your system, as it works on mine. I have an idea for fixing it though. In your copy of the code, in file tsv-filter/src/tsv-filter.d, in lines 228 and 229, try replacing the calls to 'toLower' with 'asLowerCase' and try to build. If that works for you, then I'll make this change to the code.

Hi,

Thanks for taking the time to look into this! I have no clue what's going on really. Tell me if there's anything I can supply you with to aid in debugging this.

I made these changes to tsv-filter.d:

Got any other ideas?

[jondegenhardt]

Um... Not great ones. Best I can tell, the linker is saying it can't find a particular template instantiation, something coming out of the D standard library. I looked the library code, there are several interacting templates, so it's not clear to me exactly what bit is failing. And, it doesn't fail on my machines. I've tried with three compilers, 2 DMD versions and an LDC version, and on Mac and Linux.

If you're comfortable with a bit a D coding, you could remove the problematic routines to get you going. What's failing to build are two case-insensitive string search tests for the tsv-filter routine. Specifically, the --istr-in-fld and --istr-not-in-fld command line options. They are lesser used options. To remove them, remove or comment out the function definitions, plus the calling code. It would be something like:

• Comment out the two lines you already tried modifying, lines 228 and 229. (istrInFld, istrNotInFld)
• The two calls at lines 561 and 562 (handlerIStrInFld, handerIStrNotInFld)
• The two command line option specification lines at lines 617, 618.

I haven't tried it, but I think that should do. Then you could at least try the routines out.

After applying the following changes to the code (one additional line to comment out that you unfortunately missed your reply @jondegenhardt) it now appears to work. Really looking forward to putting tsv-utils-dlang to the test now! I work with large tab separated text daily and this looks like it will suit me perfectly :). Thanks for the help to find a way around my issue @jondegenhardt, really appreciate it!

@boulund Have you tried any of the more recent releases? If so, let me know if you are still seeing this issue.

[boulund]

@jondegenhardt Sorry for my late reply. No I haven't tried any later versions; I didn't really have the need to after I got it working :).

I just tried with a fresh clone of the repository and it still fails (still using dmd v2.068.1).

@boulund Thanks for follow-up. I'm going to leave this issue closed unless it causes you further trouble. I haven't been able to reproduce it. I wouldn't mind getting the specifics of your environment though (OS, etc) in case anyone else encounters this.

[boulund]

It appears to compile just fine with the latest version of DMD
