Hi All, When I hit make I get:

Maybe that's because my workaround for an earlier problem was not so great... Despite having been very careful and the earlier "specs" thing looking correct, I was getting: $ readelf -l a.out | grep Requesting [Requesting program interpreter: /tools/lib64/ld-linux-x86-64.so.2] in chapter 6.20 so I ran: $ gcc -dumpspecs | sed -e 's@/tools@@g' > `dirname $(gcc --print-libgcc-file-name)`/specs That created /usr/lib/gcc/x86_64-pc-linux-gnu/7.2.0/specs and the problem went away. All the other tests in this section were fine to start with and remained so. Could there be a connection between these two things? BTW, I hacked past the perl pthread thing by adding -lpthread to the Makefile, but in the following chapter about XML::Parser the same problem arises and this time you can't hack the makefile cos it's generated every time.
