Package: libbenchmark-dev
Version: 1.6.0-1
Severity: serious
Tag: patch
Dear maintainer,
the latest version of libbenchmark-dev has a regression that breaks the
libbenchmark_main.a static library for users who do not use
link-time-optimzation. This is very similar to bug #968461:
https://bugs.debian.org/968461
Relevant excerpt from a build log:
/usr/bin/ld:
/usr/lib/x86_64-linux-gnu/libbenchmark_main.a(benchmark_main.cc.o): plugin
needed to handle lto object
/usr/bin/ld:
/usr/lib/x86_64-linux-gnu/libbenchmark_main.a(benchmark_main.cc.o): plugin
needed to handle lto object
/usr/bin/ld:
/usr/bin/../lib/gcc/x86_64-linux-gnu/11/../../../x86_64-linux-gnu/crt1.o: in
function `_start':
(.text+0x20): undefined reference to `main'
The static library has no actual object code in it, only the
intermediate code used for link-time optimization. You need to
replace the -flto flag with -ffat-lto-objects to ensure that both
the intermediate code AND the actual object code will be emitted:
