doxyres crashes, presumably due to missing refid

[dgront]

My doxyrest run on Mac OS ends wtih (that is just last 5 lines):

warning: can't find inner compound refid: d0/d0f/classstd_1_1wostringstream
warning: can't find inner compound refid: d3/d05/classstd_1_1wstring
warning: can't find inner compound refid: d0/d29/classstd_1_1wstringstream

Segmentation fault: 11

When I try id under lldb, I see that:

I understand the problem comes from the missing nodes (e.g. d0/d29/classstd_1_1wstringstream), but in fact I'm absolutely interested in them. All the missing nodes concern standard C++ libary which I'm not willing to document. Can doxyrest just go over this errors?

Did you build Doxyrest from the latest sources or used the precompiled release v1.1.1? The call stack leads to the location where a bug in the support lib was causing crashes in Doxyrest under certain (usually, invalid or misspelled) command line options. The bug was fixed a while ago, but the binaries for Doxyrest have not been re-released after that.

I have just pushed a tag to re-build the GitHub release with patched support lib (if it passes all tests, Travis CI/Appveyor CI should upload binaries soon).

Meanwhile, one question -- what's the exact command line which leads to a crash?

[vovkos]

Also, the above warnings may be safely ignored, the segfault has no connection to those.

[dgront]

OK, so after a few quick tests I learned that "-o" command line flag was mandatory; it was crashing because I didn't use it.

[vovkos]

It shouldn't crash even if -o is omitted. Crash due to wrong/missing paths was fixed quite a while ago. There still was a problem -- doxyrest attempted to generate the output .rst files in the root directory whenever -o was omitted. The latest commit fd01477 should take care of that, too
