<para><userinput>CPPFLAGS=-Dre_max_failures=re_max_failures2:</userinput> 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.</para>
|
|
|
|
<para><userinput>PR_PROGRAM=/usr/bin/pr:</userinput> When 'diff' is called
|
|
with the '-i' flag, it tries to find 'pr' at the location specified with the
|
|
PR_PROGRAM variable. By default, this variable points to '/bin/pr', but since
|
|
we install 'pr' in /usr/bin, we need to change this.</para>
