I'm trying to install R-2.4.0 on AIX 5.2. But, I have an error message during the compilation. Can you help me please? I have used : export OBJECT_MODE=64 export CC=/usr/bin/xlc_r export F77=/usr/bin/xlf_r export CXX=/usr/bin/xlC_r export LDFLAGS='-brtl' export CFLAGS='-O2 -qstrict' export FFLAGS='-O2 -qstrict' export CXXFLAGS='-O2 -qstrict' ./configure --prefix =/home/..... --without-readline That's ok. But, when I made the command "make", I obtained : ...... /usr/bin/xlc_r -Wl,-G -Wl,-bexpall -Wl,-bnoentry -brtl -o grDevices.so chull.o devNull.o devPicTeX.o devPS.o devQuartz.o init.o -lm make[5]: Leaving directory `/home/source/R-2.4.0/src/library/grDevices/src' make[4]: Leaving directory `/home/source/R-2.4.0/src/library/grDevices/src' *** caught segfault *** address 6f6c207761732096, cause 'memory not mapped' Traceback: 1: .Call("R_lazyLoadDBfetch", key, file, compressed, hook, PACKAGE = "base") 2: lazyLoadDBfetch(key, datafile, compressed, envhook) 3: .Call("La_dgesv", a, b, tol, PACKAGE = "base") 4: solve.default(rgb) 5: solve(rgb) 6: drop(whitexyz %*% solve(rgb)) 7: make.rgb(red = c(0.625, 0.34), green = c(0.28, 0.595), blue = c(0.155, 0.07), gamma = 1.8, white = "D65", name = "Apple RGB") 8: eval(expr, envir, enclos) 9: eval(i, envir) 10: sys.source(codeFile, env, keep.source = keep.source) 11: try(sys.source(codeFile, env, keep.source = keep.source)) 12: loadNamespace(package, lib.loc, keep.source, TRUE, TRUE) 13: code2LazyLoadDB(package, lib.loc = lib.loc, keep.source = keep.source, compress = compress) 14: tools:::makeLazyLoading("grDevices") aborting ... make[3]: *** [all] Segmentation fault (core dumped) make[3]: Leaving directory `/home/source/R-2.4.0/src/library/grDevices' make[2]: *** [R] Error 1 make[2]: Leaving directory `/home/source/R-2.4.0/src/library' make[1]: *** [R] Error 1 make[1]: Leaving directory `/home/source/R-2.4.0/src' make: *** [R] Error 1 Thanks in advance.
