Bug ID: 102389
Summary: [12 Regression] --with-build-config=bootstrap-lto
bootstrap is broken due to r12-3491
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: build, lto
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
checking locale.h presence... libtool: link: nm .libs/lto-plugin.o | |
/bin/sed 's/.* //' | sort | uniq > .libs/liblto_plugin.exp
./libtool: eval: line 1118: syntax error near unexpected token `|'
./libtool: eval: line 1118: `nm .libs/lto-plugin.o | | /bin/sed 's/.* //' |
sort | uniq > .libs/liblto_plugin.exp'
Makefile:466: recipe for target 'liblto_plugin.la' failed
make[4]: *** [liblto_plugin.la] Error 2
----- CUT ----
After r12-3491-g9e58de3ce00, nm is used but libtool's configure breaks (it
looks like it was always broken, just we did not use that feature of libtool
until now):
