From: David Wells Date: Fri, 9 Oct 2020 00:58:44 +0000 (-0400) Subject: Add a quick check for matching boost versions. X-Git-Tag: v9.3.0-rc1~1017^2 X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c0aa1399014f70f7fe7fbc2ceefba2c6f80f3462;p=dealii.git Add a quick check for matching boost versions. This addresses a problem a user had recently with inscrutable crashes caused by mixed boost versions. Credit goes to Daniel Jodlbauer for reporting the issue. --- diff --git a/cmake/configure/configure_2_boost.cmake b/cmake/configure/configure_2_boost.cmake index 24463063bc..9386f2f597 100644 --- a/cmake/configure/configure_2_boost.cmake +++ b/cmake/configure/configure_2_boost.cmake @@ -92,6 +92,20 @@ MACRO(FEATURE_BOOST_CONFIGURE_BUNDLED) # We need to set this path before calling the configure function # to be able to use the include paths in the checks.
