Bug ID: 117211
Summary: Building gcc configured with --enable-coverage=opt
fails with a link error after r15-4286-gc397a8c12296b7
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: gcov-profile
Assignee: unassigned at gcc dot gnu.org
Reporter: jamborm at gcc dot gnu.org
CC: jakub at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-linux-gnu
Target: x86_64-linux-gnu
Starting with commit r15-4286-gc397a8c12296b7 (Jakub Jelinek:
libcpp, genmatch: Use gcc_diag instead of printf for libcpp
diagnostics), I cannot build GCC when configured as:
../src/configure --enable-languages=c,c++ --disable-bootstrap
--enable-coverage=opt --enable-host-shared
which we use (with more languages enabled) to generate
https://gcc.opensuse.org/gcc-lcov/ (I admit I do not know why we use
--enable-host-shared or if it is strictly necessary).
The build fails with link errors like:
