Binutils-2.37

Reference: 8.18. Binutils-2.37. Apply a patch to fix the core of the build system: 

patch -Np1 -i binutils-2.37-qlnx-1-20220203.patch

The above patch did made binutils to fit to the qLinux filesystem layout. The next patch fixes the build system to change dynamically created  libtool  files: 

patch -Np1 -i binutils-2.37-qlnx-2-20220203.patch

This second patch adds a sed command to several  Makefile.in . Additional it disables make-all in po in subdir ld also. Reason is an unclear behavior: make enters subdir po and returns immediately with “nothing to be done in all”. But somewhere in between the file  ld/libtool  will be recreated/rewritten - thus the sed command to fix  /dev/null  before entering po will be reverted. Really weird.

Another patch makes fixes to the sources itself to make the final binaries qLinux compliant: 

patch -Np1 -i binutils-2.37-qlnx-3-20220203.patch

An error in the building system causes the shipped man pages to be empty. Remove them, so the man pages will be rebuild correctly: 

sed -i '63d' etc/texi2pod.pl
find -name \*.1 -delete

Use a separate directory for the build: 

mkdir -v build
cd       build

Configure and compile the package: 

../configure --prefix=/qlnx \
             --enable-gold \
             --enable-ld=default \
             --enable-shared \
             --enable-plugins \
             --disable-werror \
             --enable-64-bit-bfd \
             --includedir=/qlnx/inc \
             --datarootdir=/qlnx/dat \
             --mandir=/qlnx/man \
             --infodir=/tmp \
             --with-system-zlib \
             --disable-perl

Then compile binutils: 

make MAKEINFO=true tooldir=/qlnx

tooldir=/qlnx     

    From the book: “Normally, the tooldir (the directory where the executables will ultimately be located) is set to $(exec_prefix)/$(target_alias). For example, x86_64 machines would expand that to /usr/x86_64-pc-linux-gnu. Because this is a custom system, this target-specific directory in /usr is not required. $(exec_prefix)/$(target_alias) would be used if the system was used to cross-compile (for example, compiling a package on an Intel machine that generates code that can be executed on PowerPC machines).”

MAKEINFO=true
    We have no texinfo installed (yet) and we don't want nor need info files at all. This sets the makeinfo command to true (as a dummy) w/o building info pages and throwing an error about missing  makeinfo ..

It is highly recommended to verify the build: 

for f in `ls binutils/*` ; do
  test -x "$f" && file "$f" &>/qlnx/dev/null && grep -q ELF "$f" && readelf -l $f | grep ld
done

Install binutils: 

make tooldir=/qlnx install -j1

In Binutils-2.37 - Pass 2 the “tooldir” was installed in  /qlnx/lib/binutils . This directory is now obsolete and shall be removed: 

rm -rf /qlnx/lib/binutils

Remove commonly not used static libraries (optional): 

rm -fv /qlnx/lib/lib{bfd,ctf,ctf-nobfd,opcodes}.a
