Undefined symbol: RcppEigen_Eigen_SSE #120

Closed brgew closed 1 year ago

brgew commented 1 year ago

Hi,

I want to load RcppEigen from a GitHub clone of the master branch. Running the R devtools command

> devtools::load_all() # in the RcppEigen clone directory

gives, finally, the message

Error in dyn.load(dll_copy_file) : 
  unable to load shared object '/tmp/Rtmp8gE2OJ/pkgload4dfc3e6993ef/RcppEigen.so':
  /tmp/Rtmp8gE2OJ/pkgload4dfc3e6993ef/RcppEigen.so: undefined symbol: RcppEigen_Eigen_SSE

I suppose I am missing something. Probably in my environment?

I am running R 4.2.2 on Debian Bullseye.

> devtools::session_info()
─ Session info --

 setting  value
 version  R version 4.2.2 (2022-10-31)
 os       Debian GNU/Linux 11 (bullseye)

I appreciate your guidance.

Thank you.

I don't use devtools, and we do not document or recommend its use. I suggest you use R CMD build . followed by the install step.

Hi,

I ran R CMD build . in the cloned RcppEigen directory and got the same result. I'll find a work-around.

I appreciate your advice. Thank you.

Can you please provide more details? The package is 10+ years old and has been tested daily at CRAN on multiple architectures. The error will likely be at your end but I cannot help with the details (or lack thereof) given.

See https://cloud.r-project.org/web/checks/check_results_RcppEigen.html, I would be happy to share logs from my Ubuntu system but they will look the same. So feel free to reopen but with pertinent detail.
