library("RQuantLib") in RStudio Server failing vs library("RQuantLib") from R in commandline succeeding

[leeutjie]

I run RStudio Server (open source) with a common library on a Linux server and we use RQuantLib extensively as a dependency. After a recent update I started noticing the following .

Inside the RStudio Server IDE:

library("RQuantLib")

gives the following error:

Error: package or namespace load failed for ‘RQuantLib’ in dyn.load(file, DLLpath = DLLpath, ...):
unable to load shared object '/usr/lib/R/library/RQuantLib/libs/RQuantLib.so':
/usr/lib/R/library/RQuantLib/libs/RQuantLib.so: undefined symbol: _ZNK8QuantLib22InflationTermStructure8baseDateEv

Running from the Rstudio terminal yields the same result (although it does load if I run R as root)

Outside RStudio Server in Linux commandline

With the same user,

library("RQuantLib")

loads successfully:

RQuantLib 0.4.24 built with QuantLib version 1.35. See https://www.quantlib.org for more on QuantLib.

In both cases,

.libPaths()

yields

/usr/lib/R/library

In both cases RQuantLib.so has the same permissions:
-rwxrwxrwx 1 root root 117M Oct 3 12:55 RQuantLib.so

RStudio Server devtools::session_info():

I have tried:

• altering the permissions with chmod -R 777
• multiple google and perplexity AI searches, but haven't come up with any viable solutions
• searching on here for RQuantLib related queries

I Am Looking For

Either a solution or some ideas on how to potentially troubleshoot, because I have no ideas left.

Can you post the output of

ldd /usr/lib/R/library/RQuantLib/libs/RQuantLib.so

from both the terminal in RStudio and the normal Linux CLI?

Sorry for the late reply. your message did not show up in my notifications.
From the ldd output we see that you seem to have two versions of QuantLib installed:

CLI (working)

 ldd /usr/lib/R/library/RQuantLib/libs/RQuantLib.so
        linux-vdso.so.1 (0x00007ffda5bec000)
        libQuantLib.so.0 => /usr/local/lib/libQuantLib.so.0 (0x00007f0b39130000)
[...]

Terminal (not working)

ldd /usr/lib/R/library/RQuantLib/libs/RQuantLib.so 
        linux-vdso.so.1 (0x00007ffee6382000)
        libQuantLib.so.0 => /lib/libQuantLib.so.0 (0x00007f6f7b6f3000)
[...]

Can you see if you can standardize on one QuantLib version on the server? Otherwise you can try to set LD_LIBRARY_PATH in such a way to have /usr/local/lib before /lib.

@rstub

ldd /usr/lib/R/library/RQuantLib/libs/RQuantLib.so

I did not realise RStudio Server was pointing to an older instance of Quantlib. Thanks!

I have uninstalled the older version and all seems to be working.
