From 42f74df6d4ffca8f6f08dfe191e441173be0f270 Mon Sep 17 00:00:00 2001 From: Brad King Date: Fri, 6 Jun 2014 13:48:06 -0400 Subject: Add basic Android platform module Create a Platform/Android module that includes Platform/Linux since Android is based on Linux. Provide only the minimal settings needed to get builds with Android NDK toolchains to work. Disable use of RPATH since the Android loader ignores it and we cannot predict the install destination anyway. Android supports soname but shared library names must end in ".so" and we cannot represent the versioned names with associated symlinks on all host operating systems anyway. However, we do want the SONAME of library files to be set so that linking to them by path to the library file produces NEEDED entries with the soname and not the path. Add a new CMAKE_PLATFORM_NO_VERSIONED_SONAME setting to tell the cmTarget::GetLibraryNames method that not to use the VERSION or SOVERSION target properties in the soname. --- Modules/Platform/Android.cmake | 9 +++++++++ Source/cmTarget.cxx | 1 + 2 files changed, 10 insertions(+) create mode 100644 Modules/Platform/Android.cmake diff --git a/Modules/Platform/Android.cmake b/Modules/Platform/Android.cmake new file mode 100644 index 0000000..e6d4fcf --- /dev/null +++ b/Modules/Platform/Android.cmake @@ -0,0 +1,9 @@ +include(Platform/Linux) + +# Android has soname, but binary names must end in ".so" so we cannot append +# a version number.
