his is the release of the Linux C library 4.2. You have to
|
|
install the source code of 0.98 pl5 to use it since fd_set is changed
|
|
and it needs <linux/ioctl.h>. You don't have to use 0.98 pl 5 kernel.
|
|
But 0.98 pl 4 kernel is necessary. You also need gcc 2.3.3 or above to
|
|
use it.
|
|
|
|
Since kernel now has the 387 emulation, we don't need soft math library
|
|
anymore.
|
|
|
|
I was told this shared image work with older kernel (newer than 0.97
|
|
pl4). I have put libnet.a and librpc.a back into libc.a.
|
|
|
|
Please get the latest binutils.TZ from tsx-11.mit.edu if you cannot
|
|
get your binaries linked with the shared libraries. Starting with this
|
|
release, I used a new structure for libraries. The different versions
|
|
of each library, i.e., static, jump table and classic shared library,
|
|
are in the same directory, /usr/lib. To illustrate, if the library is
|
|
named foo, then the static version is libfoo.a. The jump table version
|
|
is libfoo.sa and the classic version is libfoo.ca. The new `ld', which
|
|
is in binutils.TZ and on the third disk of the Linux Base System on
|
|
tsx-11.mit.edu, searches for the jump table library by default. You
|
|
can overwrite it by adding -static or -nojump to `ld' or 'gcc'. The
|
|
jump table and classic versions are not compatible with each other.
|
|
The static library should be used as a last resort. You can rename your
|
|
old shared libraries, notablely Xfree386, to fit the new scheme. The
|
|
script should look something like that:
|
|
|
|
----------
|
|
#!/bin/sh
|
|
|
|
cd /usr/X386/lib
|
|
for l in shlib/jump/*
|
|
do
|
|
s=`basename $l .a`
|
|
mv $l $s.sa
|
|
done
|
|
for l in shlib/nojump/*
|
|
do
|
|
s=`basename $l .a`
|
|
mv $l $s.ca
|
|
done
|
|
----------
|
|
|
|
Please make sure it works right before you run it.
|
|
|
|
You can get them from tsx-11.mit.edu under pub/linux/GCC. The
|
|
file names are image-4.2.TZ, extra-4.2.TZ, gxx-2.3.TZ, inc-4.2.TZ,
|
|
jump-4.2.TZ and libc-4.2.TZ.
|
|
|
|
Please read ChangeLog for details of the bug fixes.
|
|
|
|
The file list:
|
|
|
|
1. image-4.2.TZ
|
|
|
|
The shared images and libraries. To install it, as root do
|
|
|
|
cd /tmp
|
|
rm -rf ./lib ./usr
|
|
tar xvvofz image-4.2.TZ
|
|
cp -av ./lib ./usr /
|
|
cd /lib
|
|
ln -sf libc.so.4.2 libc.so.4
|
|
|
|
If you have an early version of libc.so.4.2 installed, you may have
|
|
to play with it, like
|
|
|
|
cd /lib
|
|
cp libc.so.4.2 libc.so.4.2.old
|
|
ln -sf libc.so.4.2.old libc.so.4
|
|
mv libc.so.4.2 foo
|
|
|
|
before you unpack image-4.2.TZ. The iostream is in libc.so.4.2. But
|
|
you have to use -nojump to use it since the external interface of
|
|
iostream may change in the future.
|
|
|
|
2. extra-4.2.TZ
|
|
|
|
libg.a and libc_p.a. To install
|
|
|
|
cd /
|
|
tar xvvofz extra-4.2.TZ
|
|
|
|
libg.a is very big. I usually do
|
|
|
|
cd /usr/lib
|
|
ln -s libc.a libg.a
|
|
|
|
since I usually do not debug the C library this way.
|
|
|
|
3. gxx-2.3.TZ
|
|
|
|
libg++.a, g++-include and genclass. It is libg++ 2.3. To install
|
|
|
|
cd /usr
|
|
tar xvvofz gxx-2.3.TZ
|
|
|
|
Iostream is in libc.a. To use it, you have to use -nojump
|
|
or -static in your LDFLAGS.
|
|
|
|
4. inc-4.2.TZ
|
|
|
|
To use the 4.2 header files, do
|
|
|
|
cd /usr
|
|
tar xvvofz inc-4.2..TZ
|
|
|
|
/usr/include/asm and /usr/include/linux may be wrong. Please make
|
|
a right symbolic link to each of them according to your Linux kernel
|
|
source tree.
|
|
|
|
5. inc1229-4.2.TZ
|
|
|
|
Change of the header files from 1129 to 4.2. It is in the testing
|
|
directory.
|
|
|
|
cd /usr
|
|
tar xvvofz inc1229-4.2.TZ
|
|
|
|
6. jump-4.2.TZ
|
|
|
|
There is also a file called jump-4.2.TZ for building the shared
|
|
image for the C library 4.2. Please install image-4.2.TZ first since
|
|
you need libgcc.a in it. The has been changed a lot thanks to
|
|
dje@sspiff.cygnus.com (Doug Evans).
|
|
|
|
7. libc-4.2.TZ
|
|
|
|
The source code of the Linux C library 4.2.
|
|
|
|
8. libc1229-4.2.TZ
|
|
|
|
Change of the source code from 1229 to 4.2. It is in the testing
|
|
directory.
|
|
|
|
9. ChangeLog
|
|
|
|
Change log for the Linux C library.
|
|
|
|
10. inc-4.2-fix.TZ
|
|
|
|
Some fixed headers failed to make into inc-4.2.TZ but are needed.
|
|
To unpack it:
|
|
|
|
cd /usr
|
|
tar xvvofz inc-4.2-fix.TZ
|
|
|
|
Please fix the file permissions after you install it.
