Bug ID: 84715
Summary: "./configure --disable-multilib && make" fails due to
"g++: error: gengtype-lex.c: No such file or
directory"
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: krichter at posteo dot de
Target Milestone: ---
Running `./configure --disable-multilib && make` fails due to
```
g++: error: gengtype-lex.c: No such file or directory
g++: fatal error: no input files
compilation terminated.
make[3]: *** [build/gengtype-lex.o] Error 1
make[3]: *** Waiting for unfinished jobs....
Makefile:2666: recipe for target 'build/gengtype-lex.o' failed
```
on a pretty empty docker image. I recreated the issue on Ubuntu 14.04, 16.04,
17.10 and 18.04 preview as well as Debian oldstable, stable and testing inside
GitLab CI, see https://gitlab.com/krichter/gcc/pipelines/18408388 for details
and
[.gitlab-ci.yml](https://gitlab.com/krichter/gcc/blob/gitlab-ci/.gitlab-ci.yml)
for the build instructions.
In case this is a user error, it'd be nice if `configure` would check that all
conditions for the configured build are fulfilled and otherwise fail with a
helpful error message.
