I'm trying to compile R 2.10.1 on AIX, and getting the following errors when it is trying to build the tools package: Error in read.dcf(file = descfile) : Line starting 'Package: tools ...' is malformed! Calls: makeLazyLoading ... code2LazyLoadDB -> loadNamespace -> parseNamespaceFile -> read.dcf Execution halted make: *** [all] Error 1 My environment and configure settings look like this: export PATH=/usr/local/bin:/opt/freeware/bin:$PATH export OBJECT_MODE=64 export LIBICONV=/opt/freeware export CC="xlc_r -q64" export CFLAGS="-O -qstrict" export CXX="xlC_r -q64" export CXXFLAGS="-O -qstrict" export AR="ar -X64" export F77="xlf_r -q64" export CPPFLAGS="-I/afs/isis/pkg/libpng/include -I/usr/local/include -I$LIBICONV/include -I/usr/lpp/X11/include/X11" export LDFLAGS="-L/usr/local/lib -L$LIBICONV/lib -L/usr/lib -L/usr/X11R6/lib" export CAIRO_CFLAGS="-I/opt/freeware/include/cairo -I/opt/freeware/include/freetype2" export CAIRO_LIBS="-L/opt/freeware/lib -lcairo" export JAVA_HOME=/usr/java14_64 export JAVA_CPPFLAGS="-I/usr/java14_64/include" export LDR_CNTRL=USERREGS ./configure --prefix=/afs/.isis/pkg/r-2.10.1 --with-tcltk=/usr/local/lib --with-tcl-config=/usr/local/lib/tclConfig.sh --with-tk-config=/usr/local/lib/tkConfig.sh I get the same error on both AIX 5.3 and AIX 6.1. I successfully compiled R 2.8.1 on AIX 5.3 with the same setup. Has anyone else seen this problem on AIX? Mike Waldron
