10431 :: Nim2.0 how to build dll without dependency of libgcc_s_seh-1.dll

  Hello expert,

  My application is an single DLL on windows, and the release should be an single dll.

  In previous Nim1.6.12, the dll do not have dependency on libgcc_s_seh-1.dll, but after build with Nim2.0, libgcc_s_seh-1.dll is needed as my dll's dependency.

  The dependency could be checked by an software call "Dependencies".

  Is there any method to

  1. to build without libgcc_s_seh-1.dll
  2. or, static build with libgcc_s_seh-1.dll

  Might be some of the default settings which have changed. Try compiling with --threads:off and see if that helps

  nim c --app:lib -d:release --passl:"-static -static-libgcc -static-libstdc++" aaa.nim

  --passl:"-static -static-libgcc -static-libstdc++"

  seems helped for static build

  I believe you are compiling something that needs libstdc++ (some c++ files?), which consequently needs libgcc. Currently libpthread is statically linked.
