-Subject: [PATCH] Improve check for ucontext
|
|
|
|
-
|
|
|
|
-The ucontext functionality is not available on all CPUs with all C
|
|
|
|
-libraries. Instead of making just assumptions based on the CPU
|
|
|
|
-architecture, this commit adds the necessary checks in wscript to verify
|
|
|
|
-the availability of the ucontext functionality, before using it in
|
|
|
|
-dbus/sigsegv.c.
|
|
|
|
-
|
|
|
|
-This avoids the long list of architecture exclusions, and make it more
|
|
|
|
-robust when building jack2 for new CPU architectures.
