Using COM in R language - com

I am trying to get the rcom package for R working. It seems to have installed ok:
> install.packages("rcom");
--- Please select a CRAN mirror for use in this session ---
trying URL 'http://mira.sunsite.utk.edu/CRAN/bin/windows/contrib/2.9/rcom_2.2-1.zip'
Content type 'application/zip' length 204632 bytes (199 Kb)

package 'rcom' successfully unpacked and MD5 sums checked
The downloaded packages are in
C:\Users\solomon\AppData\Local\Temp\Rtmpzb5oi4\downloaded_packages
updating HTML package descriptions
Then I try to run something:
>comCreateObject("Excel.Application");
Error: could not find function "comCreateObject"
What am I missing, the manual tells me that comCreateObject is the appropriate command. However, the manual's version is somewhat old. Anyone else have any insights?

I can see a couple of potential problems here - rcom has a weird installation.
Did you load the package - that is, run library(rcom) after installing it? I know, I know - but I forget that step all the time, and it would definitely give you the "could not find function" error.
Did you run the installstatconnDCOM() command? I almost didn't notice it telling me to do this.

"invalid version 0 on git_proxy_options" from libgit2: cause? fix? walk-around?

I'm getting this error "invalid version 0 on git_proxy_options" from libgit2. This did not happen until very recently (I have recompiled my code so it may be a version issue). I'm not using a proxy. Does anyone know anything about this? What causes this message? Is there anything I can do to stop the failure? Either a fix or or a work-around will do.
Specifically, I am using the Rust crate git2 version 0.13.23. I am doing a fetch that triggers the error. This is on Fedora 34 on x86_64. I have searched on this but there does not seem to be any matches that help.
git2 = {version="0.13.22", features = ["vendored-libgit2"]}
in Cargo.toml fixed the issue.
Interesting...
I had upgraded libgit2 to 1.3.0 from 1.1.1. That broke my existing cargo install, so I unpacked the previous libgit2.so.1.1 with a symlink to libgit2.so.1. That's when this error condition showed up. After thinking a bit I decided to symlink libgit2.so.1.3 to libgit2.so.1.1 and it built my new cargo version which linked to the new libgit2.so.1.3. Then I deleted my libgit2.so.1.1 stuff. Kinda weird, and usually you expect things not to work when it has been linked to a previous .so version.

AIX 7.1 missing Xm/Xm.h header

I've written a sample c file which includes Xm/Xm.h. When compile it, I have the following error, "fatal error: Xm/Xm.h: No such file or directory"
I'm using AIX 7.1. What package do I need to install to fix this problem and where can I find it? I was not able to find anything online regarding this issue. Thank you.
I just got the same error message.
You need to install (with installp on Aix):
either openmotif (and openmotif-dev)
or lesstif2-dev (smaller then openmotif, and can be enough)
(as mentioned in this answer)

casperjs.bat on windows fails with cannot find module cli.js error

I'm trying out casperJS to run some automated tests. On windows. I followed this installation guide but am stuck.
when I try to run a simple test from the command line like this:
casperjs.bat smoketest.js
I get the following error:
Error: Cannot find module 'C:/code/base/main/Shared/casperjs\modules\cli.js'
I checked, and the file cli.js does exist under the specified path.
I thought the problem could be the mixture of forward and backward slashes in the path, but I edited the bootstrap.js casper code to hard code the path and it made no difference - it still the cannot find module.
I'm have tried this using phantomJS version 1.9.0, and 1.8.2.
Anyone know what I am doing wrong?
Has anyone had success running casper on Windows?
This is due to a bug in PhantomJS 1.9.0 that does not allow for absolute path loading in Windows. Afaik, this should only be apparent if you are using a master build of CasperJS (v1.1).
This bug has been fixed, but is not yet in the Windows binary. You can compile it yourself if you'd like, but that can take quite a bit of time.
I was using the master build of casper. With the latest released version, 1.0.2, it works fine.

File upload issue in CI

I am using CI and facing a problem while uploading file.
It gives a message mentioned below.
==================================================
Severity: Warning
Message: escapeshellarg() has been disabled for security reasons
Filename: libraries/Upload.php
Line Number: 1066
In some answers, I found that it is a server issue and CI has nothing to do with it. Now, is there any way to upload file bypassing the escapeshellarg() or is there any libraries I can use that doesn't require escapeshellarg()?
Please help.
I'm not sure which specific version of CI you're using, but the latest version does a check for that function before using it.
Take a look at the code here:
$cmd = function_exists('escapeshellarg')
? 'file --brief --mime '.escapeshellarg($file['tmp_name']).' 2>&1'
: 'file --brief --mime '.$file['tmp_name'].' 2>&1';
I'd say either upgrade or update the code manually.

Not getting TBB to compile test examples

I am not getting TBB to work. I am following the steps in the "Getting started" document.
I am doing the following steps:
downloading the linux files + the sources files.
extracting them in 1 directory
calling make
going to tbb.../bin calling source tbbvars.sh intel64
going to examples/Getting_started/sub_string_finder
calling make
I then get the error:
sub_string_finder.cpp:32:30: fatal error: tbb/parallel_for.h: No such file or directory
I really googled a lot but can't find any related stuff.
I did also try to add some -I statement but it didnt help
I assume it is kind of a including/linking problem but I dont know how to fix.
This is all done on fedora 16 64bit. (kernel 3.1.4) // TBB version 4.0
The solution was to install tbb-devel package.
