Hi,
I'm trying to register my native routines using R_registerRoutines
(...). I can compile the code, but the loader cannot resolve the symbol:
undefined symbol:
_Z18R_registerRoutinesP8_DllInfoPK12R_CMethodDefPK15R_CallMethodDefS3_S6
_
$ nm bgx.Rcheck/bgx/libs/bgx.so | grep R_registerRoutines
U
_Z18R_registerRoutinesP8_DllInfoPK12R_CMethodDefPK15R_CallMethodDefS3_S6
_
Why does it have this funny name? If I look at libR.so, I get an
ordinary symbol name:
$ nm ~/lib64/R/lib/libR.so | grep R_registerRoutines
0000000000032f80 T R_registerRoutines
I get normal symbol names for R functions not in Rinternals.h and
there is no problem there. For example:
nm bgx.Rcheck/bgx/libs/bgx.so | grep Rprintf
U Rprintf
$ nm ~/lib64/R/lib/libR.so | grep Rprintf
0000000000129690 T Rprintf
The shared library dependencies are also fine:
$ ldd bgx.Rcheck/bgx/libs/bgx.so
libR.so => /home/et04/lib64/R/lib/libR.so (0x0000002a95676000)
libstdc++.so.6 => /usr/lib64/libstdc++.so.6
(0x0000002a95a80000)
libm.so.6 => /lib64/tls/libm.so.6 (0x0000002a95c70000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x0000002a95df7000)
libc.so.6 => /lib64/tls/libc.so.6 (0x0000002a95f02000)
libRblas.so => /home/et04/lib64/R/lib/libRblas.so

libreadline.so.4 => /usr/lib64/libreadline.so.4
(0x0000002a96383000)
libncurses.so.5 => /usr/lib64/libncurses.so.5
(0x0000002a964bc000)
libdl.so.2 => /lib64/libdl.so.2 (0x0000002a96618000)
/lib64/ld-linux-x86-64.so.2 (0x000000552aaaa000)
My LD_LIBRARY_PATH environmental variable is set appropriately.
Any ideas?
Thanks,
E
