When doing the build the samples processing gets as far as the 'survex' folder and things go wrong:
therion 5.3.11 initialization file: /etc/therion.ini reading ... done configuration file: thconfig.1 reading ... done reading source files ... done preprocessing database ... therion: error -- file import -- cave1.th [11] -- unable to open file
cave1.th definitely exists. why would 'source cave1.th' fail?
source foo.th has just worked fine in q-marks and pocket-topo and morphing/sample1 etc. I am perplexed.
aha. the issue is not that cave1.th is unable to be openned. It's that line 11 of cave1.th is: import cave.3d -surveys use and _that_ is what's failing. There is a cave.3d in the directory with sensible permissions. I suspect the issue is a new version of survex, so that file is in version 8 format. I suspect something in thimport.cxx (shouldn't therion be using the survex img.c/img.h files rather than implementing it's own parser?) Ah. I see it has a copy of img.h, but it's it's own copy in 'extern', not the actual copy from survex (I guess as survex doesn't actually provide a survex-dev package with these headers in, therion can't avoid having an internal copy). It seems that line 4 of a v8 file has a date like: @1377747129 whearas v6 and v7 had: Sun,2011.02.27 02:37:02 GMT (confirmed by checing the 3dformat.htm and 3dformat-old.htm files in the survex docs) Not sure if that's actually what was breaking. Updating to the current img.* caused: extern/img.o: In function img_write_item': img.c:(.text+0x3f38): undefined reference to max' which needed this putting back to fix: /* In C++ code, #include<algorithm> and use std::max and std::min instead. */ #ifndef __cplusplus /* Return max/min of two numbers. */ /* May be defined already (e.g. by Borland C in stdlib.h) */ /* NB Bad news if X or Y has side-effects... */ # ifndef max # define max(X, Y) ((X) > (Y) ? (X) : (Y)) # endif # ifndef min # define min(X, Y) ((X) < (Y) ? (X) : (Y)) # endif #endif That lets it build, but now processing samples/survex/thconfig.1 causes a segfault: ../../therion thconfig.1 therion 5.3.11 cavern - Survex 1.2.7 initialization file: /etc/therion.ini reading ... done configuration file: thconfig.1 reading ... done reading source files ... done preprocessing database ... Segmentation fault Which I guess isn't very surprising. So I could go back to survex 1.2.6 and build therion. That would presumably build OK, but I supsect I'd hit problems with and v8 .3d files in data? Can someone who groks C++ take a look at this and see what's needed to make it work with survex 1.2.7, as that's out now. We'll need to fix it at some point. My curent sources are here if someone wants to start from there: http://wookware.org/software/therion/therion-5.3.11-wook.tar.gz BTW building therion now gives an awful lot of: thdb1d.h: In constructor ‘thdb1ds::thdb1ds(const char*, thsurvey*)’: thdb1d.h:176:19: warning: passing NULL to non-pointer argument 1 of ‘std::list<_Tp, _Alloc>::list(std::list<_Tp, _Alloc>::size_type, const value_type&, const allocator_type&) [with _Tp = thdata*; _Alloc = std::allocator<thdata*>; std::list<_Tp, _Alloc>::size_type = long unsigned int; std::list<_Tp, _Alloc>::value_type = thdata*; std::list<_Tp, _Alloc>::allocator_type = std::allocator<thdata*>]’ [-Wconversion-null] whinges. I have no idea how to fix this apaprt from disabling the warning. C++ gurus welcome to improve the code. Wookey -- Principal hats: Linaro, Emdebian, Wookware, Balloonboard, ARM http://wookware.org/
