Slitaz64 - compiling and linking - toolchain

 

compiling and linking - toolchain

make clear, we are talking about the toolchain.

1.

/usr/lib/gcc/x86_64-slitaz-linux-gnu/12.2.0/crtend.o crtn.o
/usr/bin/ld: cannot find crt1.o: No such file or directory
/usr/bin/ld: cannot find crti.o: No such file or directory
collect2: error: ld returned 1 exit status

# tazpkg -sp crt1.o
Search result for package "crt1.o"
glibc-dev

# tazpkg -lf glibc-dev | grep crt[1in].o
/usr/lib64/Mcrt1.o
/usr/lib64/Scrt1.o
/usr/lib64/crt1.o
/usr/lib64/crti.o
/usr/lib64/crtn.o
/usr/lib64/gcrt1.o
/usr/lib64/grcrt1.o
/usr/lib64/rcrt1.o

2.

echo 'int main(){}' | gcc -xc -

> # echo 'int main() { return 0; }' > test.c
> # gcc -v -o test.o test.c

ensure that the basic functions (compiling and linking) of the toolchain are working as expected.
If everything is working correctly, there should be no errors,

3.

8.5.1. Installation of Glibc

Prepare Glibc for compilation:
../configure --prefix=/usr \
--disable-werror \
--enable-kernel=3.2 \
--enable-stack-protector=strong \
--with-headers=/usr/include \
libc_cv_slibdir=/usr/lib

The meaning of the configure options:
[..]
libc_cv_slibdir=/usr/lib
This variable sets the correct library for all systems. We do not want lib64 to be used.

8.5.2.3. Configuring the Dynamic Loader
By default, the dynamic loader (/lib/ld-linux.so.2) searches through /usr/lib for dynamic libraries that are needed by programs as they are run. However, if there are libraries in directories other than /usr/lib, these need to be added to the /etc/ld.so.conf file in order for the dynamic loader to find them. Two directories that are commonly known to contain additional libraries are /usr/local/lib and /opt/lib, so add those directories to the dynamic loader's search path.

1. config.log
$ grep -A10 int config.log

| main ()
| {
|
| ;
| return 0;
| }
configure:3505: error: in `/home/slitaz/wok/xorg-xf86-video-amdgpu/source/xorg-xf86-video-amdgpu-22.0.0':
configure:3507: error: C compiler cannot create executables
See `config.log' for more details.

2. Installation of Glibc

Caution

At this point, it is imperative to stop and ensure that the basic functions (compiling and linking) of the new toolchain are working as expected. To perform a sanity check, run the following commands:

echo 'int main(){}' | gcc -xc -
readelf -l a.out | grep ld-linux

If everything is working correctly, there should be no errors, and the output of the last command will be of the form:

[Requesting program interpreter: /lib64/ld-linux-x86-64.so.2]

Note that for 32-bit machines, the interpreter name will be /lib/ld-linux.so.2.

If the output is not shown as above or there was no output at all, then something is wrong. Investigate and retrace the steps to find out where the problem is and correct it. This issue must be resolved before continuing on.

Once all is well, clean up the test file:

rm -v a.out
