Subject: [PATCH 08/17] testsuite: build plugins with -std=c++11
|
|
|
e88ed2 |
|
|
|
e88ed2 |
Various testsuite plugins fail when built within DTS with e.g.:
|
|
|
e88ed2 |
cc1: error: cannot load plugin ./diagnostic_plugin_test_paths.so: /builddir/build/BUILD/gcc-11.1.1-20210623/obj-x86_64-redhat-linux/x86_64-redhat-linux/libstdc++-v3/src/.libs/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by ./diagnostic_plugin_test_paths.so)

These turn out to C++14's sized deletion

(see https://en.cppreference.com/w/cpp/memory/new/operator_delete):

Looks like plugin.exp is building the test plugins against the
|
|
|
e88ed2 |
freshly-built libstdc++, and then trying to dynamically load them
|
|
|
e88ed2 |
against the system libstdc++.
|
|
|
e88ed2 |
|
|
|
e88ed2 |
This patch forces the use of -std=c++11 when building these test plugins,
|
|
|
e88ed2 |
to sidestep the problem.
