When installing Diffutils using glibc-2.1.x on your base system, it may be necessary to use a fix to prevent a variable name conflict. The following commands can be used in this case. Note that these commands can also be used for other glibc versions so if you aren't sure, then use the first version.
export CPPFLAGS=-Dre_max_failures=re_max_failures2 && ./configure --prefix=$LFS/usr && unset CPPFLAGS && make LDFLAGS=-static && make install |
If you are using a newer glibc version (2.2.x), you can use the following commands to install Diffutils:
./configure --prefix=$LFS/usr && make LDFLAGS=-static && make install |
CPPFLAGS=-Dre_max_failures=re_max_failures2: The CPPFLAGS variable is a variable that's read by the cpp program (C PreProcessor). The value of this variable tells the preprocessor to replace every instance of re_max_failures it finds by re_max_failures2 before handing the source file to the compiler itself for compilation. This package has problems linking statically on systems that run an older Glibc version and this construction fixes that problem.
The Diffutils package contains the cmp, diff, diff3 and sdiff programs.
cmp and diff both compare two files and report their differences. Both programs have extra options which compare files in different situations.
The difference between diff and diff3 is that diff compares 2 files, diff3 compares 3 files.
sdiff merges two files and interactively outputs the results.
Diffutils-2.7 needs the following to be installed:
sh from the bash package
ld from the binutils package
as from the binutils package
chmod from the fileutils package
cp from the fileutils package
mv from the fileutils package
rm from the fileutils package
cc from the gcc package
egrep from the grep package
grep from the grep package
make from the make package
sed from the sed package
basename from the sh-utils package
date from the sh-utils package
cat from the textutils package
tr from the textutils package
