"\legendbox" "\loadpicture" and absolute paths
by rowena 14 Mar '21

14 Mar '21

Hello, I am using the "\loadpicture" capability in "\legendbox" constructs to include map sections, elevations, etc. It all works nicely on my PC where I am using relative paths to the pdf files. My club has a desire to archive the map data for posterity - ie if my pc dies or I go walkabout, the map data should still be available so that others can add to the maps as they are extended. I would prefer to have the images included using relative pathnames, rather than absolute pathnames, so that future explorers can download the map data and extend it, without having to duplicate my file hierarchy. How can I include relative paths in the \loadpicture functionality? Thanks, Rowena

Scale dependant error when using area fills
by Tom Foord 20 Jan '19

20 Jan '19

Hi all I'm having some problems compiling a project which includes debris area fills. Depending on the exact symbol fill that I use, I am getting strange scale-dependant errors which seem to cause the compiler to loop endlessly until I force it to stop. I originally noticed the problem when using a custom area fill that I made by modifying the standard a_debris_AUT symbol fill. I've attached my modified metapost definition in the attached text file 'a_debris_WUG.txt'. The error occurs for any scale between 1:2000 and 1:4483 (outside of this range the project compiles fine). See attached output log 'Output log - a_debris_WUG.txt'. As you can see, the file seems to loop over and over again. Initially I thought this problem was specific to my custom fill, but then I noticed that I also get a similar error when using the standard a_debris_AUT fill, however this time the error only occurs when the scale is set to exactly 1:2000 (any other scale seems to be fine). See attached output log 'Output log - a_debris_AUT.txt'. Can anyone help with this problem? Thanks Tom

Therion 5.4.1 Windows Installer incomplete installs
by Bruce Mutton 16 Oct '17

16 Oct '17

Things are getting weirder. Usually I have just installed one version of Therion over top of whatever version I have installed, but wonder if this might be contributing to issues I have here. After I have installed 5.4.1 over top of 5.4.0. If I open a thconfig file, with Help About I get 5.4.1 reported, as below If I then open a .th2 drawing file, I get 5.4.0 reported, as below So with two instances of XTherion open at the same time, each is reporting a different version. Same thing happens installing 5.4.1 88c8a06 over top of 5.4.1. The drawing editor still reports 5.4.0 Perhaps a harmless bug/omission or something odd with the installer? Initial drawing suggests the drawing editor is behaving like 5.4.1 (triangular survey stations). Bruce From: Therion [mailto:therion-bounces@speleo.sk] On Behalf Of Bruce Mutton via Therion Sent: Monday, 29 May 2017 9:44 AM To: 'List for Therion users' <therion(a)speleo.sk> Cc: Bruce Mutton <bruce(a)tomo.co.nz> Subject: [Therion] Therion 5.4.1 Windows crash if survex loop-closure I've just started catching up on a drawing project since 5.4.1 has been released. A while back I reported problems with beta versions of Therion related to 'loop-closure survex'. They were fixed in 5.4.0 Now using 5.4.1 those projects/thconfigs that crashed before now seem to be OK, but I have now found another project/thconfig that crashes with 5.4.1 but not with 5.4.0 5.4.1 runs OK with 'loop-closure therion' but gets killed by Windows 10 when I use 'loop-closure survex'. Am still using survex 1.2.27. I have attached the log file with 'loop-closure survex'. Not sure if it is related, but I notice that if I install 5.4.1 'Install Only for Me' it will not overwrite a previously installed 5.4.0, even though the installer does not report any errors or problems to the user. Ie it fails even though it looks like it has worked just fine. To get 5.4.1 to overwrite 5.4.0 I need to "Install for all users". Bruce

Import a scrap into another scrap (or th2-file)
by torstein finnesand 11 Oct '17

11 Oct '17

Hi fellows, Sometimes I realize that two scraps should have been one (for instance scrap A in A.th2 should have been a part of scrap B in B.th2), in particular when it's difficult to join them. It's easy to insert the xvi file into the scrap B file. But I have to draw it again. Is there any workaround here? Torstein Finnesand Norway

Re: [Therion] Linux and DistoX (Wookey)
by Marco Corvi 30 Jun '17

30 Jun '17

So, thanks to me giving a competent person (who also doesn't own any Windows or Android devices) a couple of distoX's that needed ... At the moment this only works with python3 and distoX1, But Stuart plans to use the topodroid codebase to work out the differences for the X2 protocol (unless anyone has a doc for this already, or Marco can tell him). wookey, i may be not precise because i do not have the docs at hand. the distox2 protocol is backward compatible. therefore, getting the calib raw data from the distox2 is the same as in distox1, namely two data packets, one for G, one for M. the commands to toggle calib mode on and off are the same, too. the computation of the calib coeff has changed a bit with firmware 2.2 (or 2.3, don't remember well) beat added three non-linear coeffs, and these are written after the other 24. there is a catch: in the distox1 those mem are set at 0xff (ie -1), so these three coeff are written with 0 getting to 0xff. the non-linear calib should not be used for older firmwares. i have not changed the linux code, and i do not think to have the time to do that. i also understand you may not want to use android, but you can use the android code and turn it in C++ the computational methods are very much C like, and the helper classes are just basic linalgebra. if you or stuart have any question, send me email marco

Therion 5.4.1 on Fedora 25 - Compile fails in loch
by Bill Gee 09 Jun '17

09 Jun '17

Hello everyone - Once again I am wrestling with the ancient problem of getting loch to compile on Fedora Linux. Below is the sequence of errors that I get. I think I can modify the Therion Makefile so that it skips loch, but I would rather not do that. Some versions ago I figured out a set of changes to the loch Makefile that allowed it to compile. The listing below shows those changes. They do not work anymore, as seen by the compiler error. In the second set of errors it is saying that some libraries cannot be found. I do not find any files by these exact names. They probably have some extension, perhaps .so? But I do not find any files with that extension either. vtkIO.so does not exist. Two questions for the group: 1) Exactly what files are missing? I very likely have them, just not where the compiler is looking. If I can find them, maybe I can add something to VTKLIBPATH. 2) Is there an easier way to deal with this? Why is it that Fedora always has problems? It should Just Work. -- Bill Gee ===== Using the providede Makefile for loch: make -C ./loch make[1]: Entering directory '/home/bgee/Installs/therion-5.4.1/loch' gcc -c -Wall -D_GNU_SOURCE -DLOCH -DLXLINUX -I/usr/lib64/wx/include/gtk3- unicode-3.0 -I/usr/include/wx-3.0 -D_FILE_OFFSET_BITS=64 -DWXUSINGDLL - D__WXGTK__ -pthread -O2 -o /home/bgee/Installs/therion.bin/loch/lxR2P.o lxR2P.c gcc -c -Wall -D_GNU_SOURCE -DLOCH -DLXLINUX -I/usr/lib64/wx/include/gtk3- unicode-3.0 -I/usr/include/wx-3.0 -D_FILE_OFFSET_BITS=64 -DWXUSINGDLL - D__WXGTK__ -pthread -O2 -o /home/bgee/Installs/therion.bin/loch/lxTR.o lxTR.c c++ -c -Wall -D_GNU_SOURCE -DLOCH -DLXLINUX -I/usr/lib64/wx/include/gtk3- unicode-3.0 -I/usr/include/wx-3.0 -D_FILE_OFFSET_BITS=64 -DWXUSINGDLL - D__WXGTK__ -pthread -Wno-deprecated -I/usr/include/freetype2 -I/usr/local/ include/vtk-5.4 -O2 -o /home/bgee/Installs/therion.bin/loch/lxOGLFT.o lxOGLFT.cxx c++ -c -Wall -D_GNU_SOURCE -DLOCH -DLXLINUX -I/usr/lib64/wx/include/gtk3- unicode-3.0 -I/usr/include/wx-3.0 -D_FILE_OFFSET_BITS=64 -DWXUSINGDLL - D__WXGTK__ -pthread -Wno-deprecated -I/usr/include/freetype2 -I/usr/local/ include/vtk-5.4 -O2 -o /home/bgee/Installs/therion.bin/loch/lxSetup.o lxSetup.cxx In file included from lxSetup.h:23:0, from lxSetup.cxx:38: lxData.h:34:25: fatal error: vtkPolyData.h: No such file or directory #include <vtkPolyData.h> ^ compilation terminated.

Loch fails to start in Debian
by Bjørn Egil Johansen 01 Jun '17

01 Jun '17

I have a fairly fresh Debian 9 Stretch 64bit install , using propietary NVIDIA-drivers. Therion from debian repositories 5.3.16-10+b4 When trying to open Loch i encountered this error: Failed to load module "canberra-gtk-module" The program 'loch' received an X Window System error. This probably reflects a bug in the program. The error was 'BadValue (integer parameter out of range for operation)'. (Details: serial 21 error_code 2 request_code 154 minor_code 3) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) I had libcanberra-gtk3-module installed, but i also installed libcanberra-gtk-module, but still could not open Loch, giving this error: The program 'loch' received an X Window System error. This probably reflects a bug in the program. The error was 'BadValue (integer parameter out of range for operation)'. (Details: serial 21 error_code 2 request_code 154 minor_code 3) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) I thing this might be a OpenGL-related error. lshw gives: *-display description: VGA compatible controller product: GM204 [GeForce GTX 970] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:33 memory:f6000000-f6ffffff memory:e0000000-efffffff memory:f0000000-f1ffffff ioport:e000(size=128) memory:c0000-dffff Aven works just fine. Aven, About Aven report is at the end ot this email. I notice that this problem is very similar to a problem Andrew Atkinson reported back in 2011. Earlier i tried running Loch in ubuntu 16.04 on the same machine with propietary nvidia-drivers and failing as well, but I never attempted any debuging on that install. I have not tried Loch with the noveau-driver. Is there any use trying it? What would be the next step to try to debug this problem?

can survey id be called recursively
by Bruce Mutton 29 May '17

29 May '17

Ok, Now I feel like a beginner, having to ask this question. I have for years created my .th files like this, more or less. input 1-BottomUpPlan.th2 map 1-BottomUpPlanCL -title "1-BottomUp plan centreline" -projection plan 1 # this works fine endmap map 1-BottomUpPlan -title "1-BottomUp plan" -projection plan 1-BottomUpPlan-s1 endmap survey 1 -title "1-BottomUp" centreline etc endcentreline endsurvey This is contrary to the current good advice, and the way TopParser works, which suggests that maps should be created inside the survey, as this makes referencing the scraps easier and more consistent when they are part of a large project. So with this brand new project, I rearranged my 1-BottomUp.th file like this, to try to follow good practice . survey 1 -title "1-BottomUp" input 1-BottomUpPlan.th2 map 1-BottomUpPlanCL -title "1-BottomUp plan centreline" -projection plan 1 # this always causes error at this location "object does not exist - 1" endmap map 1-BottomUpPlan -title "1-BottomUp plan" -projection plan 1-BottomUpPlan-s1 endmap centreline etc endcentreline endsurvey Trouble is, the Therion Compiler always reports an error "object does not exist - 1" when I try to create a small map with just the centreline of survey 1. I have tried a number of variations of the above, with versions from 5.3.16 to 5.4.1, and the only way I can get it to compile is with the arrangement at the top of this post; how I have always done it for years and years. So it looks like Therion is complaining about calling the survey "1" from within the definition of survey "1". I would not have thought this were a problem, as it seems like Therion is generally happy to do this sort of thing. Is it some kind of namespace problem? Or is there some other thing I am missing? Is it not possible to create a map of containing only a survey centreline, from within that same survey? Bruce

Therion 5.4.1 Windows crash if survex loop-closure

I've just started catching up on a drawing project since 5.4.1 has been released. A while back I reported problems with beta versions of Therion related to 'loop-closure survex'. They were fixed in 5.4.0 Now using 5.4.1 those projects/thconfigs that crashed before now seem to be OK, but I have now found another project/thconfig that crashes with 5.4.1 but not with 5.4.0 5.4.1 runs OK with 'loop-closure therion' but gets killed by Windows 10 when I use 'loop-closure survex'. Am still using survex 1.2.27. I have attached the log file with 'loop-closure survex'. Not sure if it is related, but I notice that if I install 5.4.1 'Install Only for Me' it will not overwrite a previously installed 5.4.0, even though the installer does not report any errors or problems to the user. Ie it fails even though it looks like it has worked just fine. To get 5.4.1 to overwrite 5.4.0 I need to "Install for all users". Bruce
