Hi:
is Automake 1.15.1 a hard requirement to build GCC 'master' ?
No. Like the error says, you only need it if you modify the makefile
templates or other configuration files.
If the build is trying to use automake, it suggests you've touched
those files so that the timestamps make them look like they've been
modified.
There's a script you can use to update timestamps of generated files
so they no logner appear to be out of date. In the GCC source tree run
'contrib/gcc_update --touch'
That should allow you to build without needing automake.
Hi Jonathan:
Thanks for your reply.
Perhaps the following details may help
you evaluate if i am missing something
and point that out.
0. the intent is do a 'out-of-source'
build
1. directory structure is
${HOME}/src/gcc
${HOME}/work/build/gcc
2. cd ${HOME}/src/gcc
git clone https://gcc.gnu.org/git/gcc.git
3. cd ${HOME}/work/build/gcc
../../../src/gcc/configure \
--prefix=${HOME}/root/gcc \
--enable-languages=c,c++ \
--disable-multilib \
--disable-werror \
--with-gnu-ld \
--enable-gcov \
--enable-__cxa_atexit \
--enable-threads=posix \
--enable-tls \
--enable-bootstrap \
--enable-maintainer-mode \
--enable-default-pie
4. The build system error'd out with the
following message.
make[3]: Entering directory
'/home/strikr/work/build/gcc/build-x86_64-pc-linux-gnu/fixincludes'
cd ../../../../../src/gcc/fixincludes ;
/bin/sh ./genfixes
./genfixes: line 61: autogen: command
not found
AutoGen appears to be out of date or not
correctly installed.
Please download and install from:
https://ftp.gnu.org/gnu/autogen/

5. installed 'autogen'
6. clean up the generated files and dir
in the 'build' directory ie.
${HOME}work/build/gcc
7. execute 'configure' script again and
now the 'automake' related error is
seen.
8. since i suspected that some files may
have changed or new ones may have got
created,
cd ${HOME}/src/gcc
git status
There don't seem to be any files whose
time stamps have changed or new ones
that got created.
Next, step in verification was to
ensure that all the steps are
performed on the 'master' branch.
9. in relation to the upstream gcc repo,
i only do git pulls as there are no
local changes.
$ git config --list
pull.rebase=true
Thanks for reading this far. What could
i be missing here ?
warm regards
Saifi.
