I am trying to deploy an Rmarkdown document to RPubs. Required data are in subfolder /Data of the directory where the app is located. Previous errors were solved by loading some (but, mysteriously, not all) libraries on separate lines ('library(). Now, it says deployment is successful, but the website https://yettas.shinyapps.io/ShinyVEST-lite/ returns:
'Error: Error: An error has occurred. Check your logs or contact the app author for clarification.' Unlike previous attempts, I do not see an Error explicitly listed in the logs (see below). I am not sure what to look for other than the word 'Error'.
Thank you in advance for your help!

I'm trying to connect with dcvviewer to a remote server whose my_config_file.dcv configuration file is given.
When I run the command :
dcvviewer my_config_file.csv
The viewer opens and then suddenly closes.
Setting RUST_BACKTRACE=full for debugging purposes, I get the following stack.

I'm running Ubuntu 22.04 with latest version of dcvviewer (NICE DCV Viewer - version 2022.2 (r4804)).
What can be wrong ?
I'm trying to install the code from this git-repo for a university project and I'm stuck because ld does not seem to be able to link lua properly. I followed the install instructions and compile the code with:
catkin_make -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 -DCMAKE_CXX_STANDARD=14
which fails with several messages like:
/usr/bin/ld: /home/felixk/catkin_ws/devel/lib/libflatland_lib.so: undefined reference to `lua_toboolean(lua_State*, int)'
/usr/bin/ld: /home/felixk/catkin_ws/devel/lib/libflatland_lib.so: undefined reference to `lua_tonumberx(lua_State*, int, int*)'
...
/usr/bin/ld: /home/felixk/catkin_ws/devel/lib/libflatland_lib.so: undefined reference to `lua_pushstring(lua_State*, char const*)'
/usr/bin/ld: /home/felixk/catkin_ws/devel/lib/libflatland_lib.so: undefined reference to `lua_isstring(lua_State*, int)'
collect2: error: ld returned 1 exit status
The code was tested and works on Ubuntu 18.04 but I'm trying to get it to work on Manjaro. The manual states that liblua5.2-dev is needed and I installed lua52 from the AUR which seems to provide the right libraries.
The output of ldd is:
ldd /home/felixk/catkin_ws/devel/lib/libflatland_lib.so | grep lua
liblua5.2.so.5.2 => /usr/lib/liblua5.2.so.5.2 (0x00007f23fd51c000)
Then I checked if /usr/lib/liblua5.2.so.5.2 exists and it does. I tried to use readelf to check whether liblua5.2.so.5.2 contains the undefined references:
readelf -s /usr/lib/liblua5.2.so.5.2

It seems like all the undefined references exist in /usr/lib/liblua5.2.so.5.2 and I don't know how to go on from here.
Other answers on SO suggest to put the #includes of lua into a extern "C" like so:
extern "C"{
#include <lua5.2/lualib.h>
#include <lua5.2/lauxlib.h>
#include <lua5.2/lua.h>
}
But I would rather not change the given code and wouldn't even know how to find out in which files lua is #included .
Optimally I would only like to change the make command catkin_make -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 -DCMAKE_CXX_STANDARD=14 to help ld to properly link but I don't know if thats possible. I'm not really familiar with make, cmake or in this case catkin_make and couldn't find out if it is possible to add linker options in the make command.
Lua can be compiled both as C ans C++ languages. This is an advertised feature of it. For that reason, Lua authors decided not to include the classic extern "C" in the headers.
Your liblua5.2.so.5.2 library was compiled in C language and the symbols are not mangled. You compiled your application in C++ mode with just including Lua headers without extern "C", so your Lua included symbols are mangled.
Solution: wrap your include with extern "C":
extern "C"
{
#include "lua.h"
}
The other solution would be to recompile Lua 5.2 as C++ language (with -x c++ compiler option for GCC and Clang, or /TP compiler option for MSVC).
I got it working thanks to prapin's answer :)
I installed lua 5.2 from source following the lua manual.
Instead of prapins suggestion to use the -x c++ compiler option I changed the following in the makefile in lua-5.2.0/src:
changed CC= gcc to CC= g++
added -shared -fPIC to MYCFLAGS= because I needed the .so file.
I hope this helps anybody with this problem who does not want to wrap the includes in extern "C"

I need to add up all the intervals (between second-to-last and last columns), but, as you can see, some rows have overlapping or partially overlapping intervals.
Before I add up all the days, I need to convert the full dataset (from which the above snippet came) into something like:
accumulated data:
configStartDate configEndDate
1: 2005-11-03 19:12:36 2007-12-12 11:03:00
2: 2011-06-17 15:40:13 2012-05-24 11:43:24
total days: 934.296
Here’s my R code for doing this (it has to be R, although I am considering re-writing it in C++ and using RCPP):
merge_intervals <- function(interval_dt){
interval_dt <- interval_dt[order(configStartDate), list(configStartDate, configEndDate)]
new_dt <- interval_dt[1, list(configStartDate, configEndDate)]
for (i in 2:dim(interval_dt)[1]) {
buff <- interval_dt[i, list(configStartDate, configEndDate)]
if (new_dt[dim(new_dt)[1], configEndDate] >= buff[, configStartDate]){
if(new_dt[dim(new_dt)[1], configEndDate] >= buff[, configEndDate]){
next
}
else{
new_dt[dim(new_dt)[1], configEndDate := buff[, configEndDate]]
}
}
else {
new_dt <- rbind(new_dt, buff)
}
}
return(new_dt)
}
Right now the whole thing takes about 0.16 seconds to run (with other calculations), but, for 3000 unique assets, that creates 8 minutes calculation time overhead.
How do I transform that for loop into something faster to reduce calculation time? Thanks!
Something like this?
df <- data.frame(
id = 1:3,
start = Sys.time() + c(0, 1000, 3000),
end = Sys.time() + c(1500, 2000, 4000)
)
library(dplyr)
df %>%
mutate(
overlap = lead(start, 1, default = TRUE) < end,
interval = cumsum(overlap)
) %>%
group_by(interval) %>%
summarise(start = min(start), end = max(end)) %>%
mutate(delta = end - start) %>%
summarise(total = sum(delta))
When I do (0x7fffffff | 0x8000000) I am getting 0xffffffffffffffff instead of the expected 0xffffffff. What am I missing?
Some sample code and output to illustrate my question.
Code:
#include <iostream>
using namespace std;
int main()
{
unsigned long long val = 0;
for (int i = 0; i < 64; i++) {
val |= 0x1 << i;
cout << i << ": " << std::hex << val << std::dec << endl;
}
return 0;
}
Output:
0: 1
1: 3
2: 7
3: f
4: 1f
5: 3f
6: 7f
7: ff
8: 1ff

Firstly your code does not do what you say in your title/question; I have edited the title.
The problem is 1 << 31. If you have 32-bit int (which apparently you do, judging by the results), this cause arithmetic overflow. In C++14 this is implementation-defined behaviour; prior to C++14 it causes undefined behaviour. Reference.
Usually the implementation-defined behaviour will be to generate the int with the sign bit set and the other bits unset. In 2's complement this value is INT_MIN. You then perform arithmetic between an unsigned long long and an int. This is defined as: the int is converted to unsigned long long.
Converting signed integers to unsigned is done by wrapping it around (modular arithmetic) modulo ULLONG_MAX+1. So the result of (unsigned long long)INT_MIN is a very large positive number, in fact 0xFFFFFFFF80000000. (To check this, add 0x80000000 to it to get 0).
So you are actually doing 0x7FFFFFFF | 0xFFFFFFFF80000000 which gives the observed result.
Later on it gets worse: 1 << 32 and larger causes undefined behaviour due to shifting by the whole width of the type.
To fix this, change 0x1 in your code to 1ull. The you will be shifting an unsigned long long, instead of an int.
because of sign extension val is an unsigned long long. But val is not what you are shifting. You are shifting 0x1, an int, then extending it to long long for the '|='
My project.clj file looks like this

What am I doing wrong? How do I get datomic working in my emacs using swank/slime.
Turns out I was executing the wrong command.
I was running lein deps and getting the following error.
...
Try downloading the file manually from the project website.
Then, install it using the command:
mvn install:install-file -DgroupId=com.datomic -DartifactId=datomic -Dversion=0.1.3157 -Dpackaging=jar -Dfile=/path/to/file
Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=com.datomic -DartifactId=datomic -Dversion=0.1.3157 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]
Path to dependency:
1) org.apache.maven:super-pom:pom:2.0
2) com.datomic:datomic:jar:0.1.3157
I saw that the README file in the downloaded datomic code also contained mention of adding datomic to my mvn. Naturally (here comes the stupid part) I assumed that they sort of said the same thing.
lein will tell you that you should execute
mvn install:install-file -DgroupId=com.datomic -DartifactId=datomic -Dversion=0.1.3157 -Dpackaging=jar -Dfile=/path/to/file
the README says you should execute
mvn install:install-file -DgroupId=com.datomic -DartifactId=datomic -Dfile=datomic-${DATOMIC-VERSION}.jar -DpomFile=pom.xml
Did you notice that the README instructions also includes a pom.xml file? Neither did I! Yeah, that is important.
Anyway, be sure to also include the pom.xml file. If you were trying to add datomic 0.1.3157 to your mvn repository, you would execute the following in the datomic directory you downloaded.
mvn install:install-file -DgroupId=com.datomic -DartifactId=datomic -Dfile=datomic-0.1.3157.jar -DpomFile=pom.xml
I posted a working project here
my usual suspect in debugging swank problems are:
is leiningen up to date
the version of lein-swank
version of emacs (Emacs 24, I have found to be much more reliable)
leftover old dependencies in the lib dir
EDIT: the correct way to get the datomic jar is as Stephen Cagle says, copied from his comment below:
mvn install:install-file -DgroupId=com.datomic -DartifactId=datomic -Dfile=datomic-${DATOMIC-VERSION}.jar
