An installation error (undefined symbol: sgecon_) can be escaped by adding LAPACK dependency

Dear Zhili,

Thank you for your fantastic package! While trying to install this package, I got an error message shown below:

Error: package or namespace load failed for ‘SBayesRC’ in dyn.load(file, DLLpath = DLLpath, ...):
 unable to load shared object '/home/XXX/R/x86_64-pc-linux-gnu-library/3.6/00LOCK-SBayesRC/00new/SBayesRC/libs/SBayesRC.so':
  /home/XXX/R/x86_64-pc-linux-gnu-library/3.6/00LOCK-SBayesRC/00new/SBayesRC/libs/SBayesRC.so: undefined symbol: sgecon_
Error: loading failed
Execution halted

I tried the installation in two environments (R3.6.3 in Ubuntu20 on WSL2 and R4.1 in CentOS), but I observed the same error.

Googling the error message, I successfully installed the package after editing src/MakeVars.

The edited src/MakeVars file is as follows, in which I simply added $(LAPACK_LIBS)

CXX_STD = CXX11
PKG_CPPFLAGS = $(SHLIB_OPENMP_CFLAGS) $(LAPACK_LIBS) -w
PKG_LIBS = $(SHLIB_OPENMP_CFLAGS) $(LAPACK_LIBS)

I hope this report will help other users install this package.

Best,

Shinichi

Hi Shinichi,

Thanks for the report. We installed the openblas package by default, hence didn't notice the issue. I suggest to install this package, as it would make the performce better.

I will have a test of the flags, whether this will affect the link to the better BLAS package or not.

Thanks for the sharing.

Regards, Zhili

Hi Zhili,

Thank you for your quick reply and your suggestion. I'll try the openblas package!

Best, Shinichi

Hi Shinichi,

Thanks. I have tested, the flag doesn't affect the link to the better BLAS package. Only the modifiction to PKG_LIBS is neccessary.

I also tested, there is also no problem when openblas is installed.

I have updated to the repository.

Thanks for your suggestion.

Regards, Zhili
