error with libmoldname.a

error with libmoldname.a

[Florent Monnier]

Hi,
One week ago a project compiled under Cygwin with CC defined as bellow
was compiling just fust fine,
CC = c:/cygwin/bin/i686-w64-mingw32-gcc.exe

But since yesterday, after a cygwin update, I get the following error:

Fatal error: Error while reading:
 C:/cygwin/usr/i686-w64-mingw32/sys-root/mingw/lib/libmoldname.a:

Does someone know what's wrong, and how to fix it?

How are you causing the error? Please show the full command line.

This is a compilation of ocaml and SDL2 together
(SDL2 from the scm of 2013-07-07, and protz OCaml (not cygwin one)
version 4.00.1)
the project is this one:
https://github.com/blue-prawn/OCamlSDL2

Again this project was compiling just fine one week ago, and after a
Cygwin update, I now get this error:

-v turns verbosity on so the second line that starts with + is the
underlying command called by the first one

Maybe flexlink needs to learn to handle empty archives? You can copy
libm.a over to libmoldname.a as another workaround.

Indeed your workaround solves the compilation error.
Thank you very much!

I've reported the problem to the author of FlexDLL.

I could temporarily solve the issue by installing the older version of
mingw64-i686-runtime (3.0b_svn5747-1 instead of 3.0b_svn5935-1)

Do not do this, this will break the compiler and some header
dependencies as well. You may need to reinstall all mingw64-* to fix the
problem.

I think flexlink upstream already mentioned this was fixed.

Yes it does.
How to update is explained in the second answer of this message:
