[R] Failure to execute R CMD SHLIB successfully
R 3.1.2 Windows 7 Colleagues I am working with c code that reads sas7bdat files into R. I have been successful in compiling and running the code in both OS X and Windows. Recently, the author of the c code added code that calls iconv.h (in order to convert encodings). Using the new version of the c code, I can run compile and run the code in OS X without problems. However, when I run the code in Windows, I encounter a series of warnings, followed by what appear to be errors — and the code is not compiled. I have installed the latest version of Rtools and I have set the path as follows: set PATH=c:\Rtools\bin;c:\Rtools\gcc-4.6.3\bin;c:\program files (c86)\gnuwin32\bin;c:\MiKTeX\miktex\bin;%R32%;c:\windows;c:\windows\system32 where R32 is the path to the 32-but version of R The command that I execute is: R CMD SHLIB -o ../compiled/Windows32.so ConvertSAS.c CKHashTable.c readstat_convert.c readstat_bits.c readstat_io.c readstat_sas.c) I get a series of warnings: gcc -m32 -IC:/PROGRA~1/R/R-31~1.2/include -DNDEBUG -Id:/RCompile/CRANpkg/extralibs64/local/include -O3 -Wall -std=gnu99 -mtune=core2 -c ConvertSAS.c -o ConvertSAS.o gcc -m32 -IC:/PROGRA~1/R/R-31~1.2/include -DNDEBUG -Id:/RCompile/CRANpkg/extralibs64/local/include -O3 -Wall -std=gnu99 -mtune=core2 -c CKHashTable.c -o CKHashTable.o gcc -m32 -IC:/PROGRA~1/R/R-31~1.2/include -DNDEBUG -Id:/RCompile/CRANpkg/extralibs64/local/include -O3 -Wall -std=gnu99 -mtune=core2 -c readstat_convert.c -o readstat_convert.o readstat_convert.c: In function 'readstat_convert': readstat_convert.c:23:9: warning: passing argument 2 of 'libiconv' from incompatible pointer type [enabled by default] iconv.h:92:37: note: expected 'const char **' but argument is of type 'char **' gcc -m32 -IC:/PROGRA~1/R/R-31~1.2/include -DNDEBUG -Id:/RCompile/CRANpkg/extralibs64/local/include -O3 -Wall -std=gnu99 -mtune=core2 -c readstat_bits.c -o readstat_bits.o readstat_bits.c: In function 'byteswap_float': readstat_bits.c:59:5: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] readstat_bits.c:60:5: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] readstat_bits.c: In function 'byteswap_double': readstat_bits.c:64:5: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] readstat_bits.c:65:5: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] gcc -m32 -IC:/PROGRA~1/R/R-31~1.2/include -DNDEBUG -Id:/RCompile/CRANpkg/extralibs64/local/include -O3 -Wall -std=gnu99 -mtune=core2 -c readstat_io.c -o readstat_io.o gcc -m32 -IC:/PROGRA~1/R/R-31~1.2/include -DNDEBUG -Id:/RCompile/CRANpkg/extralibs64/local/include -O3 -Wall -std=gnu99 -mtune=core2 -c readstat_sas.c -o readstat_sas.o readstat_sas.c: In function 'sas_read_header': readstat_sas.c:204:20: warning: variable 'a2' set but not used [-Wunused-but-set-variable] readstat_sas.c: In function 'sas_parse_page_pass1': readstat_sas.c:788:23: warning: variable 'subheader_type' set but not used [-Wunused-but-set-variable] readstat_sas.c:770:14: warning: variable 'page_type' set but not used [-Wunused-but-set-variable] readstat_sas.c: In function 'sas_parse_page_pass2': readstat_sas.c:861:27: warning: variable 'subheader_type' set but not used [-Wunused-but-set-variable] readstat_sas.c: In function 'parse_sas7bdat': readstat_sas.c:1029:9: warning: implicit declaration of function 'dprintf' [-Wimplicit-function-declaration] followed by a series of errors: gcc -m32 -shared -s -static-libgcc -o ../compiled/Windows32.so tmp.def ConvertSAS.o CKHashTable.o readstat_convert.o readstat_bits.o readstat_io.o readstat_sas.o -Ld:/RCompile/CRANpkg/extralibs64/local/lib/i386 -Ld:/RCompile/CRANpkg/extralibs64/local/lib -LC:/PROGRA~1/R/R-31~1.2/bin/i386 -lR readstat_convert.o:readstat_convert.c:(.text+0x42): undefined reference to `_imp__libiconv' readstat_sas.o:readstat_sas.c:(.text+0x10b5): undefined reference to `_imp__libiconv_close' readstat_sas.o:readstat_sas.c:(.text+0x1126): undefined reference to `_imp__libiconv_open' readstat_sas.o:readstat_sas.c:(.text+0x1808): undefined reference to `dprintf' readstat_sas.o:readstat_sas.c:(.text+0x1da1): undefined reference to `_imp__libiconv_open' readstat_sas.o:readstat_sas.c:(.text+0x1de4): undefined reference to `_imp__libiconv_close' collect2: ld returned 1 exit status The errors all reference libiconv. Note that the first line in the errors references extralibs64. I don’t understand where this is coming from since the gcc command is created by R CMD SHLIB using the 32-fit version of R. I replaced both instance of extralibs64 with extralibs32 but the identical error messages appear. Does anyone have an idea as to the problem here? Any help would be
