* build: fix erroneous overwriting of flagsSaleem Abdulrasool2014-03-121-2/+2
| | | | | | | | | | Always use list(APPEND) as it will perform the desired action even if the list is empty or previously unset. The first set is harmless, however, the subsequent set was overwriting the previous flag setup resulting in an improper compilation command being generated. This manifested as a build failure on Linux when using cmake + ninja. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@203638 91177308-0d34-0410-b5e6-96231b3b80d8
* build: fix add_definition abuse in CMakeSaleem Abdulrasool2014-03-121-5/+8
| | | | | | | | | add_definitions is meant for adding C preprocessor definitions. Modern cmake suggests use of the CMAKE_CXX_FLAGS for the purposes of pushing flags to the compilation commands. Simply switch to the modern form given that we are already requiring a new enough cmake. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@203637 91177308-0d34-0410-b5e6-96231b3b80d8

* Make it possible to link against libstdc++ as well as libsupc++ with CMake.Peter Collingbourne2013-10-061-5/+14
| | | | | | | | | | | | | | | Linking against libstdc++, rather than libsupc++, is probably better for people who need to link against clients of libstdc++. Because libsupc++ is provided only as a static library, its globals are not shared between the static library and the copy linked into libstdc++. This has been found to cause at least one test failure. This also removes a number of symbols which were multiply defined between libstdc++ and libc++, only when linking with libstdc++.

* G M: Attached is a patch for libcxx's cmake file.Howard Hinnant2013-10-051-1/+3
| | | | | | | | | I've changed it so we don't set highest level warnings (all) for MSVC when building projects using cmake and instead leave the default. That's /W4 on my machine and seems to be ok. With all warnings on for msvc, we see literally thousands of warnings. 99.99% aren't relevant and just obscure the ones that are. I think the user can still override things if they want something different from the command line when using cmake. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@192010 91177308-0d34-0410-b5e6-96231b3b80d8

* Explicitly specify -Wno-error if LIBCXX_ENABLE_WERROR is false.Alexey Samsonov2013-10-021-0/+3
| | | | | | | | | libcxx doesn't build with -Werror because of #warnings in its source code. But when libcxx is built as an external LLVM project, it inherits LLVM build flags, breaking the build if LLVM_ENABLE_WERROR is enabled. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@191814 91177308-0d34-0410-b5e6-96231b3b80d8

* Andrew Morrow: The current CMake setup for libc++ incorrectly uses the variableHoward Hinnant2012-08-051-1/+2
| | | | | | | | | | | | LLVM_ENABLE_ASSERTIONS instead of LIBCXX_ENABLE_ASSERTIONS when figuring out what _DEBUG/NDEBUG defines to set. It also tries to test the non-existent variable 'uppercase_CMAKE_BUILD_TYPE', which the top level LLVM CMakeLists.txt sets up, but which the top level libc++ CMakeLists.txt currently does not. Changing the variable name tested and creating the uppercase release name variable allows libc++ to honor the LIBCXX_ENABLE_ASSERTIONS option correctly. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@161308 91177308-0d34-0410-b5e6-96231b3b80d8
