libcurl | standard libcurl library into airplay applications

Im writing a SDK for Windows and Mac OS in C++, and im using CMake. On windows, I'd like the compiled DLL to contain all necessary dependencies, instead of having separate DLLs for all third party libraries im using.

Here are the relevant sections of the MakeFile:

OS: Ubuntu 20.04.3 LTS

I am currently install the languageserver packages on R, to use the R VS Code extension.

But when I execute the install.packages("languageserver") in R with the Ubuntu's terminal, I have this error:

I am having problems changing font in R. For some reasons, it seems that R can not find the font I am asking (any of them, actually). I double-checked that the fonts are indeed installed on my system (Linux Mint 20.3). It looks like to be related to x11(), but it appears to be supported on my machine.

Any ideas appreciated.

One of the requirement for libcurl to be thread safe is that the underlying SSL library should be thread safe.

According to documentation of GnuTLS, it is thread safe by design.

The GnuTLS library is thread safe by design, meaning that objects of the library such as TLS sessions, can be safely divided across threads as long as a single thread accesses a single object. This is sufficient to support a server which handles several sessions per thread. Read-only access to objects, for example the credentials holding structures, is also thread-safe.

However there are few use cases that needs to be taken care.

A gnutls_session_t object could also be shared by two threads, one sending, the other receiving. However, care must be taken on the following use cases:

• The re-handshake process in TLS 1.2 or earlier must be handled only in a single thread and no other thread may be performing any operation.

• The flag GNUTLS_AUTO_REAUTH cannot be used safely in this mode of operation.

• Any other operation which may send or receive data, like key update (c.f., gnutls_session_key_update), must not be performed while threads are receiving or writing.

• The termination of a session should be handled, either by a single thread being active, or by the sender thread using gnutls_bye with GNUTLS_SHUT_WR and the receiving thread waiting for a return value of zero (or timeout on certain servers which do not respond).

• The functions gnutls_transport_set_errno and gnutls_record_get_direction should not be relied during parallel operation.

Does libcurl take care of above use cases?

I'm new to R. I'm looking for a script to connect to an Azure Table, and I found some useful information in this thread: Connecting to Azure Table Storage in R

However, when I run the script I get an error very similar to the one that the user posting the question had, and I cannot figure out what's wrong.

This is the code I used (credentials have been modified):

I've read some ways to do what I want but none of them worked and they end up using the same method.

I've tried this solution, which I couldn't make it work...

Here's what I get outputed:

I am deploying multiple R versions on multiple virtual desktops. I've built 3.6.3 and 4.1.2 R from source on Ubuntu 18.04.3 LTS. None of them finds the system-wide Rprofile.site file in /etc/R or the system certificates in /usr/share/ca-certificates. However R (3.4.4) installed with APT has no such problems. I used Ansible, but for the sake of this question I reproduced the deployment for one host with a shell script.

I've installed libcurl on ubuntu 20.4 and I've been playing around with it. I decidedly wanted to create a program that would write a file from the internet. So I wrote this.

Please tell me the nuances of using the option CURLSHOPT_LOCKFUNC ?

I found an example here.

I can't quite understand, is there an array of mutexes used to block access to data?

--Here is this part of the code from the example:
