Dear list,
I have one or several problems with compiling ROracle under OS X
10.4.7 (ppc) and R 2.3.1, using the Oracle client v. 10g:
1) The default build process produces an empty dll: When running R
CMD INSTALL, for some reason gcc is invoked with -arch i386 for
compiling RS-DBI.c and RS-Oracle.c, but with -arch pcc for building
the library. Not surprisingly, the build is not successful, though it
does not crash, but only warns:
R CMD SHLIB -o ROracle.so RS-DBI.o RS-Oracle.o
gcc-4.0 -arch ppc -flat_namespace -bundle -undefined suppress -L/usr/
local/lib -o ROracle.so RS-DBI.o RS-Oracle.o -L/opt/oracle/product/
10g/client/lib -L/opt/oracle/product/10g/client/network/lib -
lclntst10 -lnbeq10 -lnhost10 -lnus10 -lnldap10 -lldapclnt10 -lnsslb10
-lntcp10 -lntcps10 -lnsslb10 -lntcp10 -lntns10 -ldl -lpoll -lm -
lpthread -L/opt/oracle/product/10g/client/lib -lm -L/Library/
Frameworks/R.framework/Resources/lib/ppc -lR
/usr/bin/ld: warning RS-DBI.o cputype (7, architecture i386) does not
match cputype (18) for specified -arch flag: ppc (file not loaded)
/usr/bin/ld: warning RS-Oracle.o cputype (7, architecture i386) does
not match cputype (18) for specified -arch flag: ppc (file not loaded)
The library installs fine, but when I call Oracle(), bad things happen:
ibrary(ROracle)
ora = Oracle()
Error in .Call("RS_Ora_init", config.params, reload, PACKAGE
= .OraPkgName) :
C entry point "RS_Ora_init" not in DLL for package "ROracle"
which is not surprising, as the .o file were never included in the
library.
Any suggestion how this can happen? And possibly be avoided?
2) Fine, so I have hand-compiled by setting -arch ppc and removing
the arguments '-march=pentium-m -mtune=prescott', and built the
library without getting the error message. Then I copy the ROracle.so
in the libs/ppc directory of the previous installation, but hsi does
not work either:
Loading required package: DBI
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library '/Users/aleplo/Library/R/library/
ROracle/libs/ppc/ROracle.so':
dlopen(/Users/aleplo/Library/R/library/ROracle/libs/ppc/
ROracle.so, 6): Symbol not found: _sqlcxt
Referenced from: /Users/aleplo/Library/R/library/ROracle/libs/ppc/
ROracle.so
Expected in: flat namespace
Error in library(ROracle) : .First.lib failed for 'ROracle'
The README file suggests to 1) set the LD_LIBRARY_PATH to the Oracle
lib directory or 2) to build a static library, however, both of these
procude the same error.
Any suggestions here?
Thanks for your time,
alexander
