Unable to build GDB 13.1 on Solaris 11.3 Sparc

Unable to build GDB 13.1 on Solaris 11.3 Sparc

[Nemo Nusquam]

I am trying (and failing) to build GDB 13.1 on Solaris 11.3 Sparc.

Here is my configuration script.

CXXFLAGS='-g3 -O0' \
CFLAGS='-g3 -O0' \
NM=/usr/bin/gnm \
SHELL=/usr/bin/bash \
AR=/usr/bin/gar \
AS=/usr/bin/as \
CC=/home/build/gcc/git/bin/gcc \
CXX=/home/build/gcc/git/bin/g++ \
../configure \
--with-mpc=/usr/local \
--with-gmp=/usr/local \
--with-mpfr=/usr/local \
--enable-64-bit-bfd \
--enable-tui \
--with-curses \
--disable-bootstrap \
--disable-binutils \
--disable-ld \
--disable-gprof \
--disable-gprofng \
--disable-gold \
--disable-gas \
--disable-sim

(Some flags taken from https://sourceware.org/gdb/wiki/BuildingNatively .)

The makefile creates ./gdb inside the build directory and then stops as 
follows:

checking for libgmp... no
configure: error: GMP is missing or unusable
gmake[1]: *** [Makefile:11447: configure-gdb] Error 1
gmake[1]: Leaving directory '/home/build/opt/gdb-13.1/bld'

I have libgmp (and building gcc 13 uses it) in /usr/local/lib:

/usr/local/lib/libgmp.a:        current ar archive, 32-bit symbol table
/usr/local/lib/libgmp.la:       commands text
/usr/local/lib/libgmp.so:       ELF 64-bit MSB dynamic lib SPARCV9 
Version 1, UltraSPARC3 Extensions Required, dynamically linked, not 
stripped, no debugging information available
/usr/local/lib/libgmp.so.10:    ELF 64-bit MSB dynamic lib SPARCV9 
Version 1, UltraSPARC3 Extensions Required, dynamically linked, not 
stripped, no debugging information available
/usr/local/lib/libgmp.so.10.4.1:        ELF 64-bit MSB dynamic lib 
SPARCV9 Version 1, UltraSPARC3 Extensions Required, dynamically linked, 
not stripped, no debugging information available

Now I note that the Makefile is compiling to 32-bit objects but I have a 
32-bit libgmp.a.  (I tried adding "-m64" but that caused other problems.)

I am stumped.  How do I proceed?

Why?  Do you want/need to debug the resulting gdb itself?  Otherwise,
just leave the defaults (-g -O2).

Probably rather CONFIG_SHELL.  Btw., it's often best to have
/usr/gnu/bin before /usr/bin in $PATH: configure scripts sometimes
assume the GNU tools and fail in weird ways with the native ones.

Unnecessary for gdb.  Even when building gcc, use --with-as=/usr/bin/as
--without-gnu-as as documented in the installation guide.  Relying on
$PATH is risky and fragile.

> CC=/home/build/gcc/git/bin/gcc \

I suppose this is a 32-bit-default gcc (i.e. configured for
sparc-sun-solaris2.11, not sparcv9-sun-solaris2.11)?  Any reason not to
use the bundled gcc 7.3.0?  That one is 64-bit-default.

This is gcc only, thus unnecessary for a gdb build.

If you're building from the gdb 13.1 tarball, you can omit those.  Btw.,
--disable-binutils is harmful: gdb depends on libbfd and won't link
without, as you've discovered.

> (Some flags taken from https://sourceware.org/gdb/wiki/BuildingNatively .)

In general, please start with the bare minimum of configure flags (like
the --with-* stuff).  Unless you known 200% what you're doing,
additional flags usually cause more harm then anything.

You can find the exact errors in gdb/config.log.  Consulting that is
usually necessary to determine what exactly went wrong.

Such as?  Please include the details so we can help.

> I am stumped.  How do I proceed?

Since your libgmp is 64-bit, you need to ensure a 64-bit build.  You can
achieve this either by using a 64-bit-default gcc/g++ or adding -m64 to
CC/CXX.  Adding it to CFLAGS/CXXFLAGS often doesn't work as expected,
unfortunately.

You should also add --build sparcv9-sun-solaris2.11 to the configure
flags.  config.guess has been badly messed with on Solaris in recent
times and misdetects the 64-bit triple.  I've given up fighting the
upstream chaos here and usually specify the correct triple explicitly.

Hope this helps.

--disable-binutils does not disable building bfd (binutils is just
another consumer of bfd, like gdb), and will not do any harm.

True, sorry for the confusion.  However, my point stands: none of those
--disable-* options are needed when building from a tarball, and keeping
configure lines as simple as possible unless proven otherwise has more
often than not proven to help things.

It's only when you build from a git checkout that they help reduce build
time, but still aren't strictly necessary.

These options are those specified on the GDB Wiki 
(https://sourceware.org/gdb/wiki/BuildingNatively).

The gar options are different than the ar options.  Specifying AR
seems necessary.

Noted though I have built dozens of different versions of GCC this way.

Solaris 11.3 came bundled with gcc-4.8.2.  I relied on config.guess, 
which specifies sparc-sun-solaris2.11.  I shall try sparcv9-sun-solaris2.11.

Again, the options were taken from the GDB Wiki.

This was a known issue in GDB 13.1, It has been fixed/changed on the
trunk and will be included with GDB 14. For pre-GDB 14, the option you
want to use for configure is --with-libgmp-prefix= . libmpfr is
similar you need to use --with-libmpfr-prefix .
These options are documented in the installation documentation for GDB
13 but they were not part of the toplevel configure which is why they
were not mentioned there. The options --with-gmp= and --with--mpfr=
were only originally used for building GCC (GCC, GDB, binutils [and
newlib] all share the same toplevel configure/make file system) and
this was why folks got confused and even more I made the fix for this
to use these options also for GDB.

This issue was recorded as
https://sourceware.org/bugzilla/show_bug.cgi?id=28500 .

Thank you, Andrew.  I will try rebuilding as you suggest.

I tried searching but I erroneously assumed it was a Solaris problem and 
found nothing relevant.
