Bug ID: 117399
Summary: make all-target-libgcc fails because gcc/as line 114
is "exec $original" and $original is --64
Product: gcc
Version: 14.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: dilyan.palauzov at aegee dot org
Target Milestone: ---
I want to compile only libgcc_s.so in order to put it in a chrooted
environment. I call
/src/gcc-14.2.0/configure --disable-multilib --enable-languages=c
--target=x86_64-unknown-linux-gnu && make all-target-libgcc
Eventually it creates x86_64-unknown-linux-gnu/libgcc, executes there
/src/gcc-14.2.0/libgcc/configure --srcdir=/src/gcc-14.2.0/libgcc
--cache-file=./config.cache --with-cross-host=x86_64-pc-linux-gnu
--disable-multilib --enable-languages=c,lto
--program-transform-name=s&^&x86_64-unknown-linux-gnu-&
--disable-option-checking --disable-year2038
--with-target-subdir=x86_64-unknown-linux-gnu --build=x86_64-pc-linux-gnu
--host=x86_64-unknown-linux-gnu --target=x86_64-unknown-linux-gnu
and this fails, printing
checking whether ln -s works... yes
