Package Information

Installation of Sharutils

Fix a heap buffer overflow, and an issue exposed by GCC-10: 

sed -i 's/BUFSIZ/rw_base_size/' src/unshar.c &&
sed -i '/program_name/s/^/extern /' src/*opts.h

Install Sharutils by running the following commands: 

sed -i 's/IO_ftrylockfile/IO_EOF_SEEN/' lib/*.c        &&
echo "#define _IO_IN_BACKUP 0x100" >> lib/stdio-impl.h &&

./configure --prefix=/usr &&
make

To test the results, issue make check.

Now, as the root user: 

make install
