From eac0a8bc3070e45047fff57e7b024a059289a36d Mon Sep 17 00:00:00 2001 From: Alex Crichton Date: Thu, 21 Jan 2016 15:36:25 -0800 Subject: bootstrap: Add directives to not double-link libs Have all Cargo-built crates pass `--cfg cargobuild` and then add appropriate `#[cfg]` definitions to all crates to avoid linking anything if this is passed. This should help allow libstd to compile with both the makefiles and with Cargo. --- src/libstd/sys/common/gnu/libbacktrace.rs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/libstd/sys/common/gnu') diff --git a/src/libstd/sys/common/gnu/libbacktrace.rs b/src/libstd/sys/common/gnu/libbacktrace.rs index f8463388384..8b3cb04030c 100644 --- a/src/libstd/sys/common/gnu/libbacktrace.rs +++ b/src/libstd/sys/common/gnu/libbacktrace.rs @@ -40,7 +40,7 @@ pub fn print(w: &mut Write, idx: isize, addr: *mut libc::c_void, errnum: libc::c_int); enum backtrace_state {} #[link(name = "backtrace", kind = "static")] - #[cfg(not(test))] + #[cfg(all(not(test), not(cargobuild)))] extern {} extern { -- cgit 1.4.1-3-g733a5
