Bug ID: 88429
Summary: Ada bootstrap fails with --disable-shared
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
Target Milestone: ---
Target: amd64-pc-solaris2.11, x86_64-pc-linux-gnu
Prompted by PR bootstrap/65725 (a Solaris bootstrap failure with
--disable-shared),
I tried both Solaris/amd64 and Linux/x86_64 bootstraps with --disable-shared:
both fail in the same way:
cp -p /vol/gcc/src/hg/trunk/local/gcc/tsystem.h rts_32
rm -f ../stamp-gnatlib-rts_32
touch ../stamp-gnatlib1-rts_32
rm -f rts_32/s-oscons-tmplt.i rts_32/s-oscons-tmplt.s

/bin/bash: line 0: cd: rts_32: Not a directory
Unlike the default (--enable-shared) case, it seems that the rts directory for
the non-default multilib is created incorrectly: with --enable-shared, I see
make THREAD_KIND=native setup-rts
make[9]: Entering directory
'/var/scratch/gcc/regression/trunk/4.17.3-gcc-gas-gld/build/gcc/ada'
rm -rf rts_32
mkdir -p rts_32
chmod u+w rts_32
while with --disable-shared, I get the creation of rts twice.
This may be related to libada/configure.ac referencing a gnatlib-plain
target for --disable-shared, which I couldn't find elsewhere.
