issues installing BiocFileCache

[sdwien]

Dear BiocFileCache Team,

I am trying to install the celldex() package and it fails reporting that several packages could not be installed, including BiocFileCache().

I am on a recently installed R 4.5.2 on Ubuntu 24 (in a virtual machine), so maybe I am still missing some system libs.

I tried several ways to install, but they all failed:

BiocManager::install("BiocFileCache")

BiocManager::install("Bioconductor/BiocFileCache")

devtools::install_github("Bioconductor/BiocFileCache")

They all fail reporting something like:

Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared object '/project/R/x86_64-pc-linux-gnu-library/4.5/curl/libs/curl.so':
libldap_r-2.4.so.2: cannot open shared object file: No such file or directory

On the Ubuntu side, I checked for this lib, and it is installed:

sudo apt install libldap2
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
libldap2 is already the newest version (2.6.10+dfsg-1+b1).
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

Is there anything else I am missing?
I would very much appreciate your input and help here.

Best regards from Vienna,
Sophia

I think this is a version mismatch issue with curl not necessarily BiocFileCache. As it looks like curl is expecting 2.4 and your system is 2.6. You could try reinstalling curl after making sure system dependencies are available sudo apt install libcurl4-openssl-dev libssl-dev libxml2-dev and then in R

remove.packages("curl")
install.packages("curl", type = "source")

Thanks a lot. Actually, the second half of your suggestion (un- and reinstalling curl in R) did the trick; I did not install anything new on the system level. Best, Sophia
