Bug ID: 28332
Summary: [11 regression] configure check for GMP is
insufficient
Product: gdb
Version: 11.1
Status: NEW
Severity: normal
Priority: P2
Component: build
Assignee: unassigned at sourceware dot org
Reporter: ro at gcc dot gnu.org
Target Milestone: ---
Host: sparcv9-sun-solaris2.11, amd64-pc-solaris.2.11
Target: sparcv9-sun-solaris2.11, amd64-pc-solaris.2.11
Build: sparcv9-sun-solaris2.11, amd64-pc-solaris.2.11
gdb's configure check for GMP is insufficient to build gdb 11.1 on Solaris
11.3:
* The bundled gmp is too old (at least for gcc's requirements), and even if it
were ok for gdb, gmp.h lives in /usr/include/gmp, thus the header isn't
found.
* A self-compiled libgmp isn't found for a 64-bit build. While the header
lives
in $prefix/include, the library lives in $prefix/lib/sparcv9 resp.
$prefix/lib/amd64 for the 64-bit case. Solaris being multilibbed, the 32-bit
libraries live in .../lib, while the 64-bit libs live in .../lib/sparcv9 etc.
subdirs.
gdb's --with-gmp-prefix is not enough to describe this situation because it
only
supports $prefix/include and $prefix/lib. Neither the Solaris 11.3-native
/usr/include/gmp directory for the header no the non-default
$prefix/lib/{sparcv9,amd64} can be described that way.
I tried configuring with LDFLAGS=-L$prefix/lib/sparcv9 so the library is found
at configure time, but this doesn't work because the link line is
gcc -o conftest -g -O2 -I/vol/gcc/include -L/vol/gcc/lib/sparcv9
conftest.c -lncurses -lsocket -lnsl -lm /vol/gcc/lib/libgmp.a
i.e. the static library is specified with a (wrong) full path.
gcc gets things right by providing --with-gmp=$dir for the default case, but
allowing to specify --with-gmp-include and --with-gmp-lib separately to allow
for specific situations.

--- Comment #1 from Rainer Orth <ro at gcc dot gnu.org> ---
I also tried passing CPPFLAGS=-I/usr/include/gmp so the bundled gmp.h is found,
but that doesn't work either because that isn't used in the subdir configure
runs.

There was a thread about unifying the two different flags approaches:

I'm arbitrarily picking one bug as the canonical one.
