Bug #: 52872
Summary: --enable-plugin; incorrrect test for "exported
symbols" and "-rdynamic" in gcc/configure.ac
Classification: Unclassified
Product: gcc
Version: 4.4.4
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: plugins
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: rai...@emrich-ebersheim.de
On systems with non empty $exeext the configure tests are failing with:
checking for exported symbols...
d:\opt\devel\gnu\gcc\MINGW_NT\x86_64-w64-mingw32\mingw-w64-runtime-trunk-svn\gcc-4.6.1\bin\objdump.exe:
'conftest': No such file
checking for -rdynamic...
d:\opt\devel\gnu\gcc\MINGW_NT\x86_64-w64-mingw32\mingw-w64-runtime-trunk-svn\gcc-4.6.1\bin\objdump.exe:
'conftest': No such file
All active branches are affected!
possible patch against trunk, see below.
I'm not really sure if this is the right thing to do for a cross setup or if we
have to use $host_exeext. Anyway, something along the lines should fix it, al
least for a native bootstrap.
