I am running my unit tests through valgrind using the <testing.launcher> ruleFor one particular test I want to use a local valgrind suppressions file.As such, I've specified the file using the --suppressions command line optionThis works fine when building from the same directory as the unit test itself (ie: the same directory in which .valgrind.supp is located).import testing ;run[ glob *.cpp ]: : : <testing.launcher>"valgrind --leak-check=full --track-origins=yes --error-exitcode=1 --quiet --suppressions=.valgrind.supp": unit_test;When building from elsewhere the file is not found, and valgrind exits with an error.How can I specify the full path (or relative path to where the build is executing from)?TIASteve
