| [28360cb] | 9 | <para>This package is known to behave badly when you have changed its default
|
|---|
| [b43aab1] | 10 | optimization flags (including the -march and -mcpu options). Glibc is
|
|---|
| 11 | best left alone, so we recommend you unsetting CFLAGS, CXXFLAGS and other
|
|---|
| 12 | such variables/settings that would change the default optimization that
|
|---|
| [f0c5c0b] | 13 | it comes with. Also, don't pass the --enable-kernel option to the configure
|
|---|
| [d8fd804] | 14 | script. It's known to cause segmentation faults when other packages like
|
|---|
| [f0c5c0b] | 15 | fileutils, make and tar are linked against it.</para>

| 54 | different language. Because these translation files have already been
|
|---|
| 55 | generated for you, there is no need for msgfmt. You'd only need msgfmt if
|

| 56 | you change the translation source files (the <filename>*.po</filename>
|
|---|
| 57 | files in the <filename class="directory">po</filename> subdirectory) which\
