Problems with require(RQuantLib)

[jmagomez]

Dear Fellows,

I am successful in installing RQuantLib, but when I require RQuantLib returns me this error:

library(RQuantLib) Error: package or namespace load failed for ‘RQuantLib’ in inDL(x, as.logical(local), as.logical(now), ...): unable to load shared object 'C:/Users/User/Documents/R/win-library/4.0/RQuantLib/libs/x64/RQuantLib.dll': LoadLibrary failure: Não foi possível encontrar o procedimento especificado. In addition: Warning message: package ‘RQuantLib’ was built under R version 4.0.2

I do not know what I have to do, because all others packages when I require, I do not receive an error message. I am working with R4.0.0 and RTools 4.0.

Thanks for your support.

Best Regards.

That suggests you were not successful in install RQuantLib as it doesn't load. We would know how you built it.

There is a binary for Windows at CRAN ....

Thanks,

I have downloaded the file from:

https://cran.r-project.org/bin/windows/contrib/4.0/

Replaced the RQuantLib installed and updated all the packages from R. So I have made the require, but I have received the same error.

After this, I removed RQuantLib and I tried to install RQuantLib from CRAN:

install.packages("RQuantLib") Installing package into ‘C:/Users/User/Documents/R/win-library/4.0’ (as ‘lib’ is unspecified) trying URL ' https://cran.rstudio.com/bin/windows/contrib/4.0/RQuantLib_0.4.12.zip' Content type 'application/zip' length 9466047 bytes (9.0 MB) downloaded 9.0 MB

package ‘RQuantLib’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in C:\Users\User\AppData\Local\Temp\RtmpiEqLUD\downloaded_packages

Finally, I received this message when I required RQuantLib:

library(RQuantLib) Error: package or namespace load failed for ‘RQuantLib’ in inDL(x, as.logical(local), as.logical(now), ...): unable to load shared object 'C:/Users/User/Documents/R/win-library/4.0/RQuantLib/libs/x64/RQuantLib.dll': LoadLibrary failure: Não foi possível encontrar o procedimento especificado. In addition: Warning message: package ‘RQuantLib’ was built under R version 4.0.2

And the RQuantLib file is available at the path mentioned above: C:\Users\User\Documents\R\win-library\4.0\RQuantLib

Sorry, but could you help me again.

Thanks a lot. Best Regards.

Please subscribe to the rquantlib mailing list at groups.io: https://groups.io/g/rquantlib

There are some Windows users on the list. I do not know what you did wrong yet your description is not entirely -- but there is no bug in RQuantLib. It builds on Windows from source at CRAN and is installable. So I am closing this as it is not really an "issue".

Ok. Thanks and one last attempt, I tried again and received that message:

Translating this sentence means: It could not find entry point for procedure EXTPTR_PTR in dynamic link library C:/Users/User/Documents/R/win-library/4.0/RQuantLib/libs/x64/RQuantLib.dll

Best Regards.
