Dear R package developers, Since the upgrade from R 3.2.x to 3.3.0 I was confronted with several problems updating/installing some R packages. Here for instance: # R R version 3.3.0 (2016-05-03) -- "Supposedly Educational" Copyright (C) 2016 The R Foundation for Statistical Computing Platform: x86_64-redhat-linux-gnu (64-bit) > install.packages("slam") Installing package into ‘/usr/lib64/R/library’ (as ‘lib’ is unspecified) trying URL 'https://cran.uni-muenster.de/src/contrib/slam_0.1-34.tar.gz' Content type 'application/x-gzip' length 46766 bytes (45 KB) ================================================== downloaded 45 KB * installing *source* package ‘slam’ ... ** package ‘slam’ successfully unpacked and MD5 sums checked ** libs ... gcc -m64 -std=gnu99 -shared -L/usr/lib64/R/lib -o slam.so apply.o grouped.o sparse.o util.o -L/usr/lib64/R/lib -lRblas -ldl -lpthread -lrt /builddir/build/BUILD/R-3.3.0/zlib-1.2.8/target/usr/lib64/libz.a /builddir/build/BUILD/R-3.3.0/bzip2-1.0.6/target/usr/lib64/libbz2.a /builddir/build/BUILD/R-3.3.0/xz-5.2.2/target/usr/lib64/liblzma.a /builddir/build/BUILD/R-3.3.0/pcre-8.38/target/usr/lib64/libpcre.a /builddir/build/BUILD/R-3.3.0/curl-7.48.0/target/usr/lib64/libcurl.a -lcurl -lidn -lssh2 -lssl -lcrypto -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -lldap -lz -lgfortran -lm -L/usr/lib64/R/lib -lR gcc: /builddir/build/BUILD/R-3.3.0/zlib-1.2.8/target/usr/lib64/libz.a: No such file or directory gcc: /builddir/build/BUILD/R-3.3.0/bzip2-1.0.6/target/usr/lib64/libbz2.a: No such file or directory gcc: /builddir/build/BUILD/R-3.3.0/xz-5.2.2/target/usr/lib64/liblzma.a: No such file or directory gcc: /builddir/build/BUILD/R-3.3.0/pcre-8.38/target/usr/lib64/libpcre.a: No such file or directory gcc: /builddir/build/BUILD/R-3.3.0/curl-7.48.0/target/usr/lib64/libcurl.a: No such file or directory make: *** [slam.so] Error 1 ERROR: compilation failed for package ‘slam’ ... The same errors occur if I try to install other packages. It seems as newer libraries are needed as CentOS 6 can provide. My kernel version is 2.6.32-642.1.1.el6.x86_64. My R-core version is 3.3.0-5.el6. Could somebody give me a hint how to solve this issue? Thx, Martin
