Bug ID: 98452
Summary: error: unknown Compiled Module Interface: no such
module
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: patrick.kox at commandoregel dot be
Target Milestone: ---
When following an article by Mr. Sidwell (link:
https://accu.org/journals/overload/28/159/sidwell/#FN02) I did a copy & paste
of his example 2 sourcecode (a simple hello world progam).
When I just try to compile the hello.cc sourcefile there is an error message
(as expected):
hello.cc:5:8: error: unknown Compiled Module Interface: no such module
5 | export import <string_view>;
| ^~~~~~
In module imported at hello.cc:5:8:
/opt/gcc-11/include/c++/11.0.0/string_view: error: failed to read compiled
module: Unknown CMI mapping
/opt/gcc-11/include/c++/11.0.0/string_view: note: imports must be built before
being imported
/opt/gcc-11/include/c++/11.0.0/string_view: fatal error: returning to the gate
for a mechanical issue
compilation terminated.
To solve this he provides a compiler command to process string_view so it can
be used in this example:
The command for that is: g++ -fmodules-ts -std=c++20 -c -x c++-system-header
string_view
This works and creates a file string_view.gcm in a subdirectory of the
gcm.cache directory.
But when I try to compile hello.cc with the command that should follow this
processing of string_view the compiler prints out a lot of error messages:
hello.cc:5:8: error: unknown Compiled Module Interface: no such module
5 | export import <string_view>;
| ^~~~~~
