Can't build RDCOMClient using rtools40 and R 4.0 - c++

A while back, I created a fork of the RDCOMClient package to keep it working with R 3.6 (https://github.com/dkyleward/RDCOMClient). People are now running into issues again because it won't work with R 4.0. The problem doesn't seem as easy to fix, and I'm hoping for some help.
If I flip Rstudio back to R 3.6 (and rtools35), I can use the package after installing with devtools::install_github(). When I try in R 4.0 (and rtools40), the package builds and I can connect over COM to an application. The first line of code below works, and xl is a COM pointer; however, trying to do anything with it (like set Excel to visible) will crash R.
xl <- RDCOMClient::COMCreate("Excel.Application")
xl[["Visible"]] <- TRUE
Again, the above works in R 3.6.
Is there is a way to continue building with the previous rtools? I came across https://github.com/r-windows/rtools-backports#readme, which talks about using rtools35 to keep building packages, so I have hope, but I don't understand how to make it happen.
Alternatively, if there are minor changes I can make to the R or cpp code that will solve my problem, I'm all ears. I'm a cpp novice, though.

This was a quick fix :
install.packages("RDCOMClient", repos = "http://www.omegahat.net/R")

Install R-4.0.0
Install Rtools35
Edit $R_HOME/etc/x64/Makeconf (for R-4.0.0-x64)
Rcmd INSTALL RDCOMClient

Rik's answer was incredibly helpful and got a version working; however, after spending a day on it, I was able to improve on it. I want to put that here in case I have to do it again. The main improvement is being able to build a working package for both 32- and 64-bit architectures. By default, R installs both, and this makes things easier when installing dependent packages.
The first two steps are the same:
Install R-4.0.0 (https://cran.r-project.org/bin/windows/base/old/4.0.0/R-4.0.0-win.exe)
Install Rtools35 (https://cran.r-project.org/bin/windows/Rtools/Rtools35.exe) in directory c:\Rtools
If (like me) you had already installed rtools40, a system environment variable named RTOOLS40_HOME is created. The first step is to change that to:
C:\rtools
If you don't have rtools40 installed, then create the RTOOLS40_HOME system environment variable.
Two changes are still needed in the make files. These are found in your R installation directory.
In etc\x64\Makeconf, add underscores to match the rtools35 directory structure by setting these values:
MINGW_PREFIX = /mingw_$(WIN)
BINPREF ?= "$(RTOOLS40_ROOT)/mingw_64/bin/"
Do the same in etc\i386\Makeconf:
MINGW_PREFIX = /mingw_$(WIN)
BINPREF ?= "$(RTOOLS40_ROOT)/mingw_32/bin/"
Do not set BINPREF as an environment variable, or this will overwrite the makefile changes (like RTOOLS40_HOME does). With these complete, finish off with the same steps that Rik outlined:
Open windows command prompt and change to the directory that contains the RDCOMClient subdirectory and type:
R CMD INSTALL RDCOMClient –-build RDCOMClient.zip
This installs RDCOMClient in the local installation of R-4.0.0 and additionally creates the file RDCOMClient_0.94-0.zip that can be installed on other systems using the following command:
install.packages("RDCOMClient_0.94-0.zip", repos = NULL, type = "win.binary")

I can confirm that the procedure delineated in the answer above leads in the right direction but a few extra steps may be required. I can also confirm that the procedure below produces a Windows binary file that can be installed and will run under R-4.0.0:
Install R-4.0.0 (https://cran.r-project.org/bin/windows/base/old/4.0.0/R-4.0.0-win.exe)
Install Rtools35 (https://cran.r-project.org/bin/windows/Rtools/Rtools35.exe) in directory c:\Rtools
Edit $R_HOME/etc/x64/Makeconf (for R-4.0.0-x64) by changing
## The rtools40 installer sets RTOOLS40_HOME, default to standard install path
RTOOLS40_HOME ?= c:/rtools40
to
## The rtools40 installer sets RTOOLS40_HOME, default to standard install path
RTOOLS40_HOME ?= c:/rtools
Download RDCOMClient-master.zip from https://github.com/omegahat/RDCOMClient (click the green Clone button and select download zip)
Unpack to a directory named RDCOMClient
Ensure that the following PATH variables are set:
C:\Program Files\R\R-4.0.0\bin\x64 (assuming this is the location where R is installed)
C:\Rtools\bin
C:\Rtools\mingw_64\bin
Add environment variable BINPREF with the following value (the final slash is important):
C:/Rtools/mingw_64/bin/
Open windows command prompt and change to the directory that contains the RDCOMClient subdirectory and type:
R CMD INSTALL RDCOMClient –-build RDCOMClient.zip
This installs RDCOMClient in the local installation of R-4.0.0 and additionally creates the file RDCOMClient_0.94-0.zip that can be installed on other systems using the following command:
install.packages("RDCOMClient_0.94-0.zip", repos = NULL, type = "win.binary")

I am using R 4.1.2 and I found RDCOMClient will crash the R Session and the above solutions were not working.
Then, I further check with the source owner and found out the solution.
https://github.com/omegahat/RDCOMClient/issues/36
Duncantl gave the solution and it works.
dir.create("MyTemp")
remotes::install_github("BSchamberger/RDCOMClient", ref = "main", lib = "MyTemp")
If that is successful, we can then load the newly installed package with
library("RDCOMClient", lib.loc = "MyTemp")

Python2 required as dependencie but already installed

First of all, sorry for my english and sorry for taking your time, I'm pretty sure the answers are online but it seems like I can't find the right keywords for this issue.
The problem: Python2 is installed but still asked as a dependency for every python2 module I want to install with my package manager.
I built python2 from source on Archlinux in a proot environment
(because I use termux on a non rooted phone and it's probably why yay did not worked as expected to install python2) and I think I did it well because "python2" open the python command line and "python2 -V" return me "Python 2.7.18", i can execute python scripts with it, etc.
I built python by downloading and uncompressing python2 from python.org, then in the uncompressed file ./configure --enable-optimization , make -s and make install.
I'm a noob so i don't know but i probably just need a way to handle python2 with pacman or a way to tell pacman that python2 is indeed installed.
repo.
I know to handle manualy built pkgs with pacman, but not software built from source. So i'v found a PKGBUILD for python2 but (again, probably because of the proot) when i use makepkg here what's happen :
[...
...
...]
==> Extracting sources...
-> Extracting Python-2.7.18.tar.xz with bsdtar
==> Starting prepare()...
bsdtar: Removing leading '/' from member names
patching file Makefile.pre.in
patch: setting attribute security.selinux for security.selinux: Permission denied
==> ERROR: A failure occurred in prepare().
Aborting...
So if anyone know how could i make makepkg works as intended or how could i tell pacman that python2 is already installed, it would totaly make my day.
PS : I know python2 is deprecated and as it's not updated anymore the security is getting worse and worse, but it's not for my main setup so don't worry. I also think i could install modules manually but it is not something i wish to do since i'd like to install the all BlackArch repo.

Could not install sudo apt-get install libshogun17

When trying to install shogun im getting this error. Can some one suggest a solution?
N: Ignoring file '50unattended-upgrades.ucf-dist' in directory '/etc/apt/apt.conf.d/' as it has an invalid filename extension
E: Unable to locate package libshogun17
Im using ubuntu operating system.
See this explanation of the origin and purpose of .ucf-dist files. This means you can either ignore the notice (that's what the N: prefix stands for) or remove said file.
sudo rm /etc/apt/apt.conf.d/50unattended-upgrades.ucf-dist
libshogun17 is not part of ubuntu by default. Currently we supply two different ppa's for xenial and trusty:
for nightly builds: https://launchpad.net/~shogun-toolbox/+archive/ubuntu/nightly
for stable releases: https://launchpad.net/~shogun-toolbox/+archive/ubuntu/stable
please follow the instruction either the given page or http://shogun.ml/install#ubuntu how to add the ppa to your system.
Note, as mentioned above those PPAs only supply packages for ubuntu trusty or xenial.

Can't find msguniq. Django 1.8, Windows 7 64 bit

I've successfully installed msguniq (can check its version), I've tried to change compatibility to windows xp and run it as administator, but still I'm getting this error:
CommandError: Can't find msguniq. Make sure you have GNU gettext tools
0.15 or newer installed.
I'm really confused because I've done everything like in this answer. I'm really out of ideas how can I fix it (also tried to change gettext.exe and xgettext.exe to windows xp compatibility).
I was having the extact same problem. And it came down to simply restart the cmd window by closing and opening it again.
Of course, you may need if not already done to install Gettext for Windows 0.15 or higher from these sources :
http://mlocati.github.io/gettext-iconv-windows/
To see how I compiled them (if you want to do it yourself) take a look at https://github.com/mlocati/gettext-iconv-windows (source)
Make sure also that the path to your gettext is in your system $PATH (python >> import sys >> print sys.path) - if not, you can add in your virtualenv folder Lib\site-packages a .pth file containing the path to your gettext folder.
Check your system path of Gettext.
Set the C:\Program Files (x86)\gettext-iconv\bin\
Not C:\Program Files (x86)\gettext-iconv\bin
Note the \ at the end.

Getting Leiningen & Cygwin Working

I am trying to get Leiningen and Cygwin working together.
One of the problems I think I have is that I have Java installed in "C:\Program Files\Java..." directory. The space appears to be causing issues.
When I try to run the lein script in Cygwin, I am getting the following error:
./lein: line 325: C:\Program Files\Java\jdk1.8.0_05\bin\java.exe : command not found
Then I thought the issue was the space. So I changed line 325 from:
"$LEIN_JAVA_CMD" \
to (for testing purposes):
"$'C:\\\Program Files\\\Java\\\jdk1.8.0_05\\\bin\\\java.exe'" \
But, I am still getting this error:
./lein: line 325: $'C:\\Program Files\\Java\\jdk1.8.0_05\\bin\\java.exe' : commande introuvable
However, this file clearly exists:
Owner#Owner-PC ~
$ ls -alh $'C:\\Program Files\\Java\\jdk1.8.0_05\\bin\\java.exe'
-rwxr-xr-x 1 Owner None 187K 8 mai 15:39 C:\Program Files\Java\jdk1.8.0_05\bin\java.exe
The lein script appears to be properly configuring Leiningen for Cygwin, however I can't get it to work.
Note that I previously installed Leiningen outside of Cygwin (I was running it in Windows' normal shell).
What could be wrong with my setup, any ideas?
I use Leiningen via Cygwin with no problems.
Start over
Start over with a fresh copy of the lein script. There should be no need to edit it.
Set your PATH to include java
The easiest solution is to set your path in ~/.profile to include the path to Java's bin directory. Lein will then find java on the path and you'll have access to java and its related tools in your shell.
export JAVA_HOME="/cygdrive/c/Program Files/Java/jdk1.8.0_05/"
export PATH="${JAVA_HOME}/bin/:${PATH}"
Restart your shell or source ~/.profile. Verify that which java finds java command. And run java to verify you get the help output.
And/or explicitly set the LEIN_JAVA_CMD and JAVA_CMD variables
Alternatively, set the LEIN_JAVA_CMD and JAVA_CMD variables used by lein in your ~/.profile
export JAVA_HOME="/cygdrive/c/Program Files/Java/jdk1.8.0_05/"
export LEIN_JAVA_CMD="${JAVA_HOME}/bin/java"
export JAVA_CMD=`cygpath -w "${LEIN_JAVA_CMD}"`
Restart your shell or source ~/.profile.
Note: You can also set a separate LEIN_JVM_OPTS and JVM_OPTS if desired, but this should not be necessary.
If you have lein previously installed on Windows and want to reach it from cygwin, then do:
on cmd:
cd C:/Users/%userprofile%/.lein/bin
mklink lein lein.bat
on cygwin:
export CYGWIN=winsymlinks:nativestrict
I feel your pain. I tried something like this myself several years ago.
You have at least two problems. One is getting lein to run as under unix as you noted. There are really two lein scripts - one for unix, the other a batch script for use under windows.
Your bigger problem is java.exe - getting the windows java executable to behave as a cygwin shell, and particular the unix lein script running in a cygwin shell, expects is messy and fragile undertaking.
I would strongly recommend either using a clojure ide that supports Windows (perhaps LightTable) or installing a full linux virtual machine with the unix java SDK and doing clojure development in that environment. Ubuntu running on virtualbox is freely available and an option I have used in the past for just this purpose.
You need to create a symbolic link to the "lein.bat" file.so you use it properly in Cygwin.
Open CMD and go to the ".lein" path (cd %userprofile%\.lein\bin) and run this: mklink lein lein.bat
#a-webb is almost right ,but there are still some steps to complete.First,you will find a folder called “.lein” where you run the lein script in cygwin,go in,copy the folder "self-installs" inside to C:\Users\yourUserName.lein
,then,add C:\Users\yourUserName.lein\bin to the environment variable $Path.
I've found the easiest way is to:
Install via the windows binaries and
Copy the lein bash script into .lein/bin
Then it should just work in cygwin.

Installing CLD libary on windows and bind to Python

I have a need to make use of Chromium's Compact Language Detector library within a Python script.
AFAIK, there are two projects that leverage this library, but I have been having troubles with getting either of them set up on a Windows 7 machine.
I had some similar problems with Mike McCandless Original Project (GoogleCode), but I then spotted Matt Sanford fork on the same Project (github). For the purpose of this question, I will focus on Matts project, as it seems to have been updated more often (but happy to get an answer that works for either project).
Downloaded the project as a zip, and extracted to my local drive.
Ran vcvarsall.bat from CMD
Then ran the build.win.cmd batch file. This ran ok.
Copied the resulting libcld.lib to ports/python/cld.lib
Tried running the setup.py but it returns with the following against line 12.
exceptions.TypeError: init() keywords must be strings
++EDIT++
Found this issue:
setup.py fails on Windows. The hackish solution to fix this is to make
pkgconfig return the dict {'define_macros': [('WIN32',None)],
'libraries': packages}
Im a bit of a rookie, but not entirely sure on the steps to implement this hack. Can anyone give me some slightly more verbose steps?
Try this patch (works for me):
diff --git a/ports/python/setup.py b/ports/python/setup.py
