From 4993174be59adc688efad49f2f9205688bd2ee26 Mon Sep 17 00:00:00 2001 From: Sergei Trofimovich Date: Sat, 28 Aug 2021 13:47:31 +0100 Subject: mk: prefert inplace library paths to system ones The link failure happens on a system with stable nix-2.3.15 installed in /usr/lib64 (it's libutil.so API differs from master): ``` LANG=C make V=1 g++ -o /home/slyfox/dev/git/nix/src/libstore/libnixstore.so \ -shared -L/usr/lib64 -Wl,--no-copy-dt-needed-entries \ src/libstore/binary-cache-store.o ... src/libstore/uds-remote-store.o \ -lsqlite3 -lcurl -lsodium -pthread -ldl -lseccomp -Wl,-z,defs -Wl,-soname=libnixstore.so -Wl,-rpath,/home/slyfox/dev/git/nix/src/libutil -Lsrc/libutil -lnixutil ld: src/libstore/binary-cache-store.o: in function `nix::BinaryCacheStore::BinaryCacheStore( std::map, ... nix/src/libstore/binary-cache-store.cc:30: undefined reference to `nix::readFile( std::__cxx11::basic_string, std::allocator > const&)' ... ... ``` This happens due to `-L/usr/lib64 -Lsrc/libutil` search path ordering. The change turns it into `-Lsrc/libutil -L/usr/lib64`.
