Linking issues

Hello everyone,

I'm having some troubles to make swift make me a static binary that uses ZIPFoundation for Linux (code : ZIPFoundation basic code · GitHub)
The command I am running is swift build -Xswiftc -static-stdlib
and I am having these outputs : [1/1] Planning buildBuilding for debugging...[1/4] Emitting module ZIPFounda -
After a bit of researching, [SR-2205] Linker fails when linking to Foundation if -static-stdlib flag is present · Issue #730 · apple/swift-corelibs-libdispatch · GitHub is the closest thing I could find;

But I'm not sure, I think I am having some ABI issues :
I suspect the swift toolchain I use was built / linked by GCC, but the linker that swift uses to link is Clang
(Is there any way I could force the swift toolchain to use GCC as the linker to verify this hypothesis ?)

Any thoughts ?

Actually, it seems that I was just missing the libstdc++-static files
