Broken build under MinGW due undefined references
Attempt to compile latest trunk (r35721) result in the following errors:

I'm running git-bisect right now, but things were fine at r35648
I believe this is caused by static-link-ext, so I'm assigning to Nobu
#1 [ruby-core:45141] Updated by luislavena (Luis Lavena) almost 6 years ago
After git bisect was done, I can confirm that r35709 (SHA1 0e60b2c6a3c5152fc4ff06054a4ae79edadf9276) introduced the breakage:
Author: nobu nobu@b2dd03c8-39d4-4d8f-98ff-823fe69b080e

static-linked-ext: into libruby
- Makefile.in, common.mk (PROGRAM): no extension libraries.
- common.mk (build-ext): pass macros for libruby.so.
- ext/extmk.rb (command_output): link extension libraries and encoding libraries into libruby.so, not ruby executable.
#2 [ruby-core:45143] Updated by luislavena (Luis Lavena) almost 6 years ago
The issue seems to be caused by the override of SOLIBS when --enable-shared is used to build Ruby:
By doing that, system libraries defined by LIBS (which later are used as SOLIBS) like ws2_32, shell32 and others are gone.
#3 Updated by nobu (Nobuyoshi Nakada) almost 6 years ago
- Status changed from Assigned to Closed
- % Done changed from 0 to 100
This issue was solved with changeset r35722.
Luis, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.
Bug #6462: EXTSOLIBS
- Makefile.in (LIBRUBY_SO): link EXTSOLIBS too.
- ext/extmk.rb (mf.macro): use EXTSOLIBS instead of SOLIBS to get rid of discard libraries needed by default. [Bug #6462]
