Building therion for HomeBrew

Hi I am building therion for HomeBrew Mac so it is a bit easier for every mac user. Is it possible to specify a prefix when compiling? I only have the option make config-macosx but I should be able to specify where the binaries are going to be copied. As per HomeBrew rules they all have to sit in their own subdirectory and just link to binaries to /usr/bin. a make config-macosx —prefix= would be ideal Thanks Chris

fixed point std error causes extreme survey network distortion
by Bruce 24 Dec '13

I got some unexpected results recently when I added some very rough gps coordinates to my survey for a cave that has three entrances. Because they are approximate I added some estimates of standard errors as below, so that I could get Therion to factor the relative accuracy into the loop closure. fix 12@01 1562372 5439558 992 20 20 20 # entrance fix 0@10 1562117 5440239 1080 5 5 20 # another entrance fix 120@05 1562124 5439500 1020 10 10 10 #entrance three With any ONE of the entrances fixed as above, the cave plots accurately - I can verify this in Google Earth. As soon as I have any two or more entrances fixed, then the cave distorts significantly, and the entrances are stretched some hundreds of metres away from the centroid of the cave. Also quite often getting 'scrap exceeding maximal scale' errors if I output to pdf. I checked this was not just a feature of that dataset by mocking up a similar situation in two other datasets, and got similar results. The work around seems to be to avoid using the standard errors; fix 12@01 1562372 5439558 992 #20 20 20 entrance fix 0@10 1562117 5440239 1080 #5 5 20 another entrance fix 120@05 1562124 5439500 1020 #10 10 10 entrance three but this then results in each gps location receiving equal weighting. I think I might have noticed this problem a few years ago, and gave up on trying to sort it out because I wasn't able to identify the characteristics of the problem well enough. Anyone else having problems like this? Or identify a reason why what I am trying to do is not possible? Or is it a bug? Bruce

PDF display
by Graham Mullan 16 Dec '13

I have just noticed that Adobe Acrobat and the (unnamed) pdf viewer currently opening from Firefox on this machine render coloured files very differently. It's not just that the tones are different, but, for example, in Acrobat boulders and the passage containing them are the same shade. In the other viewer the boulders render a darker tone than the remainder of the passage. Same goes for calcite flows, though not, seemingly, for sand. Graham

It's strange, but I thought that the whole point of pdf was that the document would present in identical fashion across displays and platforms. Has anyone tried printing from different rendering engines & seeing in what ways the results differ? Screen display is all very well, but if you are having printing done, especially by a print shop whose software you have no control over, how do you know what the results are going to look like before you have coughed up the (frequently not inconsiderable) price. What I do know is that if I export to jpg from, Acrobat then the results do seem to look the same as the Acrobat rendition & those are what get incorporated into journals. But for A1 or A0 posters I give pdf files to the print shop. As yet, as far as memory tells me (I have none to hand) they look like the Acrobat rendition, but others may have different experiences to me. Graham

Therion et al on Win 7 or 8.1
by Bruce 07 Dec '13

I'm staring down the barrel of having to migrate away from Windows XP. To help me get started on the decision making process, are there any tales of terror or reassurance from the Therion family of application users with Win7 or Win8.1? To name a few applications that need to integrate well, a text editor (in my case Notepad++), Therion, Survex, PocketTopo, Topparser and Foxit or Adobe pdf readers. For example Michael had (has?) a problem where Win7 will not open thconfig files from the os explorer window, whereas windows xp works fine. I think it gets stuck with wish84 as I mentioned on http://therion.speleo.sk/wiki/doku.php/windows Bruce
