From cc2e1f8ee1d28a772c0309b226e996359180124a Mon Sep 17 00:00:00 2001 From: Samuel Holland <samuel@sholland.org> Date: Sun, 16 Sep 2018 16:35:41 +0000 Subject: [PATCH 15/23] test/linkage-visibility: Ensure symbols are visible to dlsym DynamicLibrary uses libc's dlsym() function internally to find symbols. Some implementations of dlsym(), like musl's, only look at dynamically- exported symbols, as found in shared libraries. To also export symbols from the main executable, pass --export-dynamic to the linker. --- src/test/run-pass-fulldeps/auxiliary/linkage-visibility.rs | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/test/run-pass-fulldeps/auxiliary/linkage-visibility.rs b/src/test/run-pass-fulldeps/auxiliary/linkage-visibility.rs index 4ea3d0d0d0..b958e1a1fc 100644 --- a/src/test/run-pass-fulldeps/auxiliary/linkage-visibility.rs +++ b/src/test/run-pass-fulldeps/auxiliary/linkage-visibility.rs @@ -8,6 +8,8 @@ // option.
