Re: antelope error in Windows 7 cygwin build of EPICS base 3.15.3

That solved it!

Thank you very much! (And for explaining what was going on; my knowledge of make is very limited, so I hadn't realized that -m32 meant it wanted a 32 bit binary; thanks!)

This is not a problem with your version of Make. The error message above
says when it's trying to link the antelope.exe program it needs to find
a copy of libstdc++.dll.a but the only one it can find is
"incompatible". If you look at the paths it's searching, it seems that
your compiler and libraries are 64-bit, but the '-m32' argument to g++
tells it you want to build a 32-bit binary, so the 64-bit version of
libstdc++.dll.a that it can find is not suitable.

Try changing your setting of the EPICS_HOST_ARCH variable to
cygwin-x86_64 instead of cygwin-x86 and I think this will clear up. You
might want to run 'make distclean' before you run 'make' again to delete
all the 32-bit .o files it built so far which you don't need.

HTH,
