I'm trying to compile R-beta on IRIX using the native MipsPro 7.4 compilers, without great satisfaction. A list of problems is given below, and any advice on solving them is appreciated.
Martyn Configuration: ------------- Here are the configuration options I am using ./configure CC=cc CXX=CC F77=f77 CPPFLAGS="-I/usr/freeware/include" LDFLAGS="-L/usr/freeware/lib32" CFLAGS="-g -O2" CXXFLAGS="-g -O2" FFLAGS="-g -O2" The CPPFLAGS and LDFLAGS are required for readline and NLS capabilities. The compilers are not optimized by default so you need to supply the relevant flags. Major problems: -------------- 1) inline function in src/extra/bzip2 The function BZ2_indexIntoF is declared inline in bzlib.c and extern in bzlib_private.h. The linker claims that the symbol is undefined. This can be solved by removing the R_INLINE keyword. I can't see another solution, and reading these guidelines on inlining ( http://www.greenend.org.uk/rjk/2003/03/inline.html ) leaves me no wiser. 2) IEEE arithmetic The standalone math library fails to compile, as the compiler chokes on the definition of ML_POSINF, ML_NEGINF and ML_NAN, e.g. > cc-1195 cc: ERROR File = mlutils.c, Line = 130 > The indicated floating-point operation result is out of range. > > double NA_REAL = ML_NAN; where ML_NAN is defined as (0.0 / 0.0) in nmath.h. The compiler flag -OPT:IEEE_NaN_inf=ON is supposed to enforce IEEE arithmetic but apparently isn't enough. Minor problems -------------- 3) Make IRIX make does not like continuation lines followed only by a comment. So, for example, these lines from src/appl/Makefile.in OBJECTS = $(SOURCES_C:.c=.o) $(SOURCES_F:.f=.o)\ @USE_EXTERNAL_BLAS_FALSE@ blas.o @COMPILE_DOUBLE_COMPLEX_FALSE@ zgemm.o which become OBJECTS = $(SOURCES_C:.c=.o) $(SOURCES_F:.f=.o) \ # blas.o zgemm.o in the Makefile, cause an error. I have worked around this by joining the two lines, but the problem recurs several times in the tests directory. I shall probably fall back on gmake. 4) Building in a setgid directory This isn't an IRIX-specific problem. The administrators provide some "scratch" space for temporary files in a setgid directory and I started building R here. All files have the group "sys" of which ordinary users are not members. This causes some difficulty with the installation of files in src/library/<libname>/inst/po. I can't give the exact error message as I have accidentally deleted the file in which I was making notes, but it's an ownership problem. 5) strptime The problem with strptime documented in the R-admin manual is still present on this system (release 6.5.27), although it is supposed to have been solved in release 6.5.22m. Briefly, is.na fails to recognize a valid POSIX time: > strptime("1910/1/1", "%Y/%m/%d") [1] "1910-01-01" > is.na(strptime("1910/1/1", "%Y/%m/%d")) [1] TRUE I have not tried the suggested work-around yet. ______________________________________________ R-devel@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
