## Updating RAPIDS
To update RAPIDS, first pull and merge [origin]( https://github.com/carissalow/rapids), such as with:
```commandline
git fetch --progress "origin" refs/heads/master
git merge --no-ff origin/master
```
Next, update the conda and R virtual environment.
```bash
R -e 'renv::restore(repos = c(CRAN = "https://packagemanager.rstudio.com/all/__linux__/focal/latest"))'
```
## Custom configuration
### Credentials
As mentioned under [Database in RAPIDS documentation](https://www.rapids.science/1.6/snippets/database/), a `credentials.yaml` file is needed to connect to a database.
It should contain:
```yaml
PSQL_STRAW:
database: staw
host: 212.235.208.113
password: password
port: 5432
user: staw_db
```
where`password` needs to be specified as well.
## Possible installation issues
### Missing dependencies for RPostgres
To install `RPostgres` R package (used to connect to the PostgreSQL database), an error might occur:
```text
------------------------- ANTICONF ERROR ---------------------------
Configuration failed because libpq was not found. Try installing:
* deb: libpq-dev (Debian, Ubuntu, etc)
* rpm: postgresql-devel (Fedora, EPEL)
* rpm: postgreql8-devel, psstgresql92-devel, postgresql93-devel, or postgresql94-devel (Amazon Linux)
* csw: postgresql_dev (Solaris)
* brew: libpq (OSX)
If libpq is already installed, check that either:
(i) 'pkg-config' is in your PATH AND PKG_CONFIG_PATH contains a libpq.pc file; or
(ii) 'pg_config' is in your PATH.
If neither can detect , you can set INCLUDE_DIR
and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
--------------------------[ ERROR MESSAGE ]----------------------------
<stdin>:1:10: fatal error: libpq-fe.h: No such file or directory
compilation terminated.
```
The library requires `libpq` for compiling from source, so install accordingly.
### Timezone environment variable for tidyverse (relevant for WSL2)
One of the R packages, `tidyverse` might need access to the `TZ` environment variable during the installation.
On Ubuntu 20.04 on WSL2 this triggers the following error:
```text
> install.packages('tidyverse')
ERROR: configuration failed for package xml2
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to create bus connection: Host is down
Warning in system("timedatectl", intern = TRUE) :
running command 'timedatectl' had status 1
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :
namespace xml2 1.3.1 is already loaded, but >= 1.3.2 is required
Calls: <Anonymous> ... namespaceImportFrom -> asNamespace -> loadNamespace
Execution halted
ERROR: lazy loading failed for package tidyverse
```
This happens because WSL2 does not use the `timedatectl` service, which provides this variable.
```bash
~$ timedatectl
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to create bus connection: Host is down
```
and later
```bash
Warning message:
In system("timedatectl", intern = TRUE) :
running command 'timedatectl' had status 1
Execution halted
```
This can be amended by setting the environment variable manually before attempting to install `tidyverse`:
```bash
export TZ='Europe/Ljubljana'
```
Note: if this is needed to avoid runtime issues, you need to either define this environment variable in each new terminal window or (better) define it in your `~/.bashrc` or `~/.bash_profile`.
## Possible runtime issues
### Unix end of line characters
Upon running rapids, an error might occur:
```bash
/usr/bin/env: python3\r: No such file or directory
```
This is due to Windows style end of line characters.
To amend this, I added a `.gitattributes` files to force `git` to checkout `rapids` using Unix EOL characters.
If this still fails, `dos2unix` can be used to change them.
### System has not been booted with systemd as init system (PID 1)
