GCC 11 and above refuses to build anything if the current directory contains a subdirectory called "specs". Unfortunately x11-misc/compose-tables does so. Reproducible: Always Steps to Reproduce: Build x11-misc/compose-tables with GCC 11 or above. Actual Results: Fails at configuration, and gcc complains "gcc: fatal error: cannot read spec file ‘./specs’: Is a directory". Note that the source directory of x11-misc/compose-tables does contain a directory called "specs", but nobody wanted gcc to assume it's a file and read it. Technically it's a backwards-incompatible behavior of GCC. However, I wonder if there's some flag that disables this behavior, and perhaps we should include those in the ebuild.
I am able to build x11-misc/compose-tables-1.8.1 with sys-devel/gcc-11.3.0 without any errors.
Please provide emerge --info and attach a full build log demonstrating the failure.
I apologize. I can post the build log, however, last night the same machine fails to build GCC-12.2.0, and I am suspecting that something else is wrong with the machine (e.g. weird environment variables or unusual system layout). I'll report back if I resolve other issues and this issue still does not go away. For now I think NEEDINFO/RESOLVED is a good status for this.
Confirmed: I set `LIBRARY_PATH="${LIBRARY_PATH}:/some/path/to/a/third/party/library"`, inadvertently adding PWD to LIBRARY_PATH and causing all kinds of build failures. I feel ashamed that I'm reporting this kind of "bug" after having used Gentoo for 11 years.
