Last change
on this file since 985fd98 was c90f09c, checked in by Gerard Beekmans <gerard@…>, 23 years ago |
added --enable-threads=posix to chapter 5-gcc, updated chapter 6 from
--enable-threads to --enable-threads=posix (for clarity, since posix is the
default).

|
---|
[1fda654] | 5 | This new patch deals with incorrect handling of weak symbols, the
|
---|
| 6 | over-optimization of calls to those weak symbols, an atexit issue and
|
---|
| 7 | the __dso_handle symbol required for atexit's proper function.</para>

[f03a32d4] | 13 | <para><userinput>--prefix=/usr:</userinput> This is NOT a typo. GCC hard

[f36a666] | 14 | codes some paths while compiling and so we need to pass /usr as the

|
---|
[13dd793] | 20 | the average, not often used. If those other compilers are needed,

[b822811] | 21 | the --enable-languages parameter can be omitted.</para>
