Hi Jonathan,
I tried also the git version as well. But that had no effect. My best guess is, that it is related to the fact, that I compile with a static linked gcc.
I tried also a shared linked gcc version (9.2.0), but there I run into other problems.
Anyway, I guess it is something like: First is compiled with the building gcc and after the shared libraries are compiled the shared library is redirected somehow to the 11er-Version which supports the dumps function. Anyway, I solved it on my side with a small hack. I exchanged inside gcc.c simply the line:
static const char *cpp_debug_options = DUMPS_OPTIONS ("");
to
static const char *cpp_debug_options = "%{d*}";
as in gcc 10.3. With that hack I was able to compile.
Best regards,
Tammo

Hi Jonathan,
thank you for your suggestions. I tried some modifications:
I first have set the environment with:
cd /opt/add_swlibs/.compile/gcc/11.2/rh6_64/gcc-11.2.0
setenv PWCCMD `pwd`
unsetenv LD_LIBRARY_PATH
setenv PATH "/opt/add_swlibs/gcc/10.3.0/rh6_64/bin:/opt/add_swlibs/binutils/2.36.1/linux60_64/bin:${PATH}"
setenv CPATH "/opt/add_swlibs/versioned_libs/0.5/include"
setenv LDFLAGS "-L/opt/add_swlibs/versioned_libs/0.5/linux60_64/lib64_static_only -Wl,-rpath,/opt/add_swlibs/gcc/11.2.0/rh6_64/lib64"
And then I tried configure and compile with:
1.
/opt/add_swlibs/.compile/gcc/11.2/rh6_64/gcc-11.2.0/configure --prefix=/opt/add_swlibs/gcc/11.2.0/rh6_64 --enable-shared --enable-threads=posix --with-pic --enable-targets=all --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --target=x86_64-pc-linux-gnu \
--disable-multilib \
--enable-__cxa_atexit --enable-gnu-indirect-function --enable-checking
and still get the dumps error message.
2.
/opt/add_swlibs/.compile/gcc/11.2/rh6_64/gcc-11.2.0/configure --prefix=/opt/add_swlibs/gcc/11.2.0/rh6_64 --enable-shared --enable-threads=posix --with-pic --enable-targets=all --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --target=x86_64-pc-linux-gnu \
--disable-multilib \
--enable-__cxa_atexit
Still get the dumps error message. Will try a little more on this.
Best regards,
Tammo

Hello Jonathan,
thank you very much for your quick answer. Maybe it is related to the fact, that I compile from tarball and do not clone the git repository.
That's the usual way people build a release. The Git repo is most
commonly used for building the tips of development branches.
I use the commands:
unset LD_LIBRARY_PATH
export PATH="/opt/add_swlibs/gcc/10.3.0/rh6_64/bin:${PATH}"
export LDFLAGS="-L/opt/add_swlibs/versioned_libs/0.5/linux60_64/lib64_static_only "
/opt/add_swlibs/.compile/gcc/11.2/rh6_64/gcc-11.2.0/configure --prefix=/opt/add_swlibs/gcc/11.2.0/rh6_64 --enable-shared --enable-threads=posix --without-local-prefix --with-pic --enable-targets=all --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --target=x86_64-pc-linux-gnu \
--with-ld=/opt/add_swlibs/binutils/2.36.1/linux60_64/bin/ld LDFLAGS=-Wl,-rpath,/opt/add_swlibs/gcc/11.2.0/rh6_64/lib64 --disable-multilib --with-as=/opt/add_swlibs/binutils/2.36.1/linux60_64/bin/as \

--with-mpc-include=/opt/add_swlibs/versioned_libs/0.5/include --with-mpc-lib=/opt/add_swlibs/versioned_libs/0.5/linux60_64/lib64_static_only \
--with-mpfr-include=/opt/add_swlibs/versioned_libs/0.5/include --with-mpfr-lib=/opt/add_swlibs/versioned_libs/0.5/linux60_64/lib64_static_only \
--with-gmp-include=/opt/add_swlibs/versioned_libs/0.5/include --with-gmp-lib=/opt/add_swlibs/versioned_libs/0.5/linux60_64/lib64_static_only \
--with-isl-include=/opt/add_swlibs/versioned_libs/0.5/include --with-isl-lib=/opt/add_swlibs/versioned_libs/0.5/linux60_64/lib64_static_only \
--with-zstd-include=/opt/add_swlibs/versioned_libs/0.5/include --with-zstd-lib=/opt/add_swlibs/versioned_libs/0.5/linux60_64/lib64_static_only
to compile. Used similar command for 10.3 (where I did not use/provide isl and zstd).
The library directory (/opt/add_swlibs/versioned_libs/0.5/linux60_64/lib64_static_only is a directory where I linked only the static libraries to link the gcc itself without dynamic dependencies. I compile for RH6, but have seen the same problem for RH7/8. For compilation I use
gcc 10.3.
You're making things far more complicated than necessary. See
https://gcc.gnu.org/wiki/InstallingGCC
Also, if you have already installed binutils to the same --prefix as
gcc then gcc will find it and use it automatically, you don't need to
use --with-as and --with-ld that way (installing all these packages to
different directories seems superficially logical, but is actually
just over-complicated and unnecessary).
I don't know why any of this would cause your problem with the specs,
but I also don't know why your configure command needs to be so long.
Have you tried simplifying your command to the minimum necessary? e.g.
remove --enable-gather-detailed-memory-stats and
--without-local-prefix ?
And why bother adding things that are the defaults anyway, like
--enable-shared --enable-threads=posix and the redundant
build/host/target options?
