Fixes for NonStop builds on 3.5 to handle OS platform header file changes.

2025-10-17T17:43:22Z

This changes handles the introduction of _POSIX_VERSION into the NonStop x86 header files that tricks OpenSSL into thinking that ucontext.h is available. Fixes #28498 Signed-off-by: Randall S.

Build: Fix circular object deps with old GCC

2024-09-17T05:19:33Z

When both -o and -MT are used, GCC 4.1 prints the object file twice in the dependency file. e.g.: foo.o foo.o: foo.c If the file name is long, then the second occurrence moves to the next line. e.g.: ssl/statem/libssl-shlib-statem_dtls.o \ ssl/statem/libssl-shlib-statem_dtls.o: ../ssl/statem/statem_dtls.c \ add-depends script scans one line at a time, so when the first line is processed, the object file becomes a dependency itself. Fix by removing -MT altogether. This also fixes makedepend for nonstop platform. Reviewed-by: Paul Dale Reviewed-by: Richard Levitte (Merged from https://github.com/openssl/openssl/pull/25455)

Add atexit configuration option to using atexit() in libcrypto at build-time.

2024-02-02T01:26:42Z

This fixes an issue with a mix of atexit() usage in DLL and statically linked libcrypto that came out in the test suite on NonStop, which has slightly different DLL unload processing semantics compared to Linux. The change allows a build configuration to select whether to register OPENSSL_cleanup() with atexit() or not, so avoid situations where atexit() registration causes SIGSEGV. INSTALL.md and CHANGES.md have been modified to include and describe this option. The no-atexit option has been added to .github/workflows/run-checker-daily.yml.

This fix removes explicit support for the SPT threading model in configurations. This also reverts commit f63e1b48ac893dd6110452e70ed08f191547cd89 that were required for SPT but broke other models.
