Bug ID: 105298
Summary: GCC-12-20220410 FTBFS for
--enable-languages=[c,c++,]d: configure: error: can't
compile D sources!: gcc/d21:
/usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.29'
not found
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: kdevel at vogtner dot de
Target Milestone: ---
Different from GCC 11.2 GCC 12 does not seem to build gdc without having
already a gdc installed. In order to overcome this I use a GCC 11.2 which is
installed in a non-std. For this puropose I set
PATH=<path_to_gcc-11.2>:$PATH
export LD_RUN_PATH=<path_to_gcc-11.2>/lib64:<path_to_gcc-11.2>/lib
before
gcc-12-20220410/configure --prefix=$inst --enable-languages=c,c++,d
where $inst ist a non-std. directory.
make bootstrap
then fails with error 2 and
configure: error: can't compile D sources!
This is caused by gcc/d21 in the objdir referencing /usr/lib64/libstdc++.so
instead of <path_to_gcc-11.2>/libstdc++.so, which is caused by RPATH
set to $inst/lib64 instead of <path_to_gcc-11.2>/lib64.
