From 79a7be6e7d543afc13467c35c47062724df1bd69 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?R=C3=A9mi=20Verschelde?= Date: Fri, 14 Feb 2020 15:32:03 +0100 Subject: [PATCH] Vulkan-Loader: Mark secure_getenv as available on Linux It's a GNU extension part of glibc since 2.17, and it was also added recently to musl libc. It doesn't seem to be available on *BSD (but also not used there by Vulkan-Loader). Could be made more thorough by doing a test compilation of a file to check for the existence of the function on the host system, but unless we run into actual issues, that's likely overkill. --- drivers/vulkan/SCsub | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/vulkan/SCsub b/drivers/vulkan/SCsub index 8d6eb6b1990..2576f68f926 100644 --- a/drivers/vulkan/SCsub +++ b/drivers/vulkan/SCsub @@ -57,6 +57,10 @@ if env['builtin_vulkan']: 'FALLBACK_DATA_DIRS=\\"%s\\"' % '/usr/local/share:/usr/share', 'FALLBACK_CONFIG_DIRS=\\"%s\\"' % '/etc/xdg' ]) + import platform + if (platform.system() == "Linux"): + # In glibc since 2.17 and musl libc since 1.1.24.
