The proper way to configure Perl is not to call `./configure.gnu` but `./Configure`: `/bin/sh ./Configure -de -Dprefix=/app/perl -Dusethreads -Duse64bitall +-Dcc=/app/sfw/gcc` [download]	[reply] [d/l] [select]

Is `/app/perl` a directory? I usually unpack a perl tarball then rename the directory to the perl version number that I just unpacked as the installation prefix. For example: `mv /opt/perl444-27-O1-5.20.0-RC1 /opt` [download] `perl444` stands for perl using gcc-4.4.4; the `27` represents the OS which is the 2.6.27 kernel; `O1`((that's capital O followed by 1) stands for the optimization flag that I will use; lastly, the version number which I'm using. Next, you probably should set the path for your compiler and its library: `export CC=/opt/444/bin/gcc export LD_LIBRARY_PATH=/usr/local/lib` [download] Then change directory: `cd /opt/perl444-27-O1-5.20.0-RC1` [download] Now, following Corion's advice: `./Configure -Dcc=/opt/444/bin/gcc -Dprefix=/opt/perl444-27-O0-5.20.0-R +C1 -DDEBUGGING` [download] Hit `Enter` and it starts the configuration.

do `make clean` or start with fresh directory (delete everything, unpack tarball, tar -zxvf perl...tar.gz )	[reply] [d/l]

This thread a little old, but I had this same issue and thought I'd chime in what went wrong for me. First, when I did my first ./Configure, I forgot to put the dash '-' before 'Dprefix'. Doing this seemed to mess up the build, since further Configures, makes, and make cleans with the correct flag didn't solve the problem. The issue resolved itself when I deleted the source folder, untarred it again from the tar file, and did the first, fresh ./Configure with the correct command: `./Configure -des -Dprefix=/home/user/localperl` So if anyone is still running into this issue, try deleting the source directory and doing it again with a freshly untarred folder.
