[Rcpp-devel] Compiler errors with RcppGSL

[Devin Heer]

Thanks.

I think, I messed up with the setting of the environment variable...due to
the following new error message:

g++ -m64 -I"C:/PROGRA~1/R/R-31~1.1/include" -DNDEBUG -IC:\Program Files
(x86)\CodeLibraries/include
-I"C:/PROGRA~1/R/R-31~1.1/library/Rcpp/include"
-I"C:/PROGRA~1/R/R-31~1.1/library/RcppGSL/include"
 -I"d:/RCompile/CRANpkg/extralibs64/local/include"     -O2 -Wall
 -mtune=core2 -c colNorm.cpp -o colNorm.o
Syntax error: "(" unexpected
make: *** [colNorm.o] Error 2
Warning message:
running command 'make -f "C:/PROGRA~1/R/R-31~1.1/etc/x64/Makeconf" -f
"C:/PROGRA~1/R/R-31~1.1/share/make/winshlib.mk"
SHLIB_LDFLAGS='$(SHLIB_CXXLDFLAGS)' SHLIB_LD='$(SHLIB_CXXLD)'
SHLIB="sourceCpp_32194.dll" WIN=64 TCLBIN=64 OBJECTS="colNorm.o"' had
status 2


I assume this error is caused by the missing quotation mark around  C:\Program
Files (x86)\CodeLibraries/include. The path I used for LIB_GSL was C:\Program
Files (x86)\CodeLibraries. I tried to fix by adjusting the environment
variable and reinstalled RcppGSL package, but the same error consists. Even
after removing the environment variable, RcppGSL still searches at this
particular place, which is obviously the place the compiler is expecting
the GSL library.

Where does the g++ compiler take that information from? How I can adjust
for that second location?

Regards
Devin
