Hi everyone,
On Windows, we require both /MD and /MT builds of OpenSSL, with Control Flow Guard enabled. To do so, we tried using these steps in cmd.exe recently when compiling 1.1.1d for /MT (64-bit shown; we also build 32-bit): $ perl Configure VC-WIN64A no-asm --prefix=<path> $ ms\do_ms $ perl -p -i.back -e "s/\/MD/\/MT/g;" makefile $ perl -p -i.back -e "s/^CFLAGS=/CFLAGS=\/GUARD:cf /g;" makefile $ perl -p -i.back -e "s/^LDFLAGS=/LDFLAGS=\/GUARD:cf /g;" makefile $ nmake $ nmake test $ nmake install_sw Unfortunately, there are failing tests (There are "Failed x/y subtests" and "Dubious, test returned..." messages for almost all tests). When we follow similar steps for 1.0.2t (by modifying ms\ntdll.mak), the tests pass for both the default /MD and the /MT modification. Is there a correct way to build OpenSSL 1.1.1d with the /MT run-time library such that the tests run successfully? Also, is there a better way to use CFG? Thanks, Michael
