* Problems (and a workaround) with zlib and Windows Dev Channel [not found] <1970878832.218554.1604175571485.ref@mail.yahoo.com> @ 2020-10-31 20:19 ` test test 2020-10-31 21:16 ` Brian Inglis 0 siblings, 1 reply; 3+ messages in thread From: test test @ 2020-10-31 20:19 UTC (permalink / raw) To: cygwin Hello! I noticed that some programs that depend on zlib stopped working and started creating stackdumps with Windows Dev Channel build 20246.1. I could not get gdb working with zlib but I figured a workaround: I recompiled zlib with cygport using the latest gcc (10.2.0) and copied the dll over the old one. That did fix the problem.

Some utilities e.g. Tortoise <VCS> also install DLL intercepts that can break Cygwin, so you have to drop them from Cygwin PATH. Do you happen to know the zlib version you were running? You can check under your local package directory: $ ls -t $PACKAGE/x86*/release/zlib/zlib0/ zlib0-1.2.11-1.tar.xz zlib0-1.2.8-3.tar.xz zlib0-1.2.8-1.tar.bz2 zlib0-1.2.7-1.tar.bz2 zlib0-1.2.5-1.tar.bz2 -- Take care.

I have had Cygwin installed for a long time now on and it has worked on every Dev Channel version until now. The only that that changed was an upgrade to a new version. I have excluded Cygwin's directory in Windows Defender settings. > Do you happen to know the zlib version you were running? Zlib is version 1.2.11-1.
