I found using
statichere could result in problem forlibrsvgbuilding.librsvgfirst generates a static library with Rust code, and next mix objects from C code and Rust code to make a dynamic library.when using
static, the resultingrlibcontains:libcompiler_rt.aand so, duplicated symbols.
It isn't a problem when linking
dylibor binary: the linker will keep only the first resolved symbol. But the waylibrsvgbuild makes the linker to see the duplicated symbols.Without
static, the generatedrlibcontains:libcompiler_rt.a(OpenBSD doesn't provide dynamic library for compiler_rt)I have backported the PR on OpenBSD ports tree and use without problem for the following program/library: rustc/cargo, firefox, ripgrep, exa, librsvg
