Hi Christian Adam, Thanks for pointing this out, I made the necessary changes to account for this. So the behavior is as follows: * If no CMAKE_BUILD_TYPE is set and no CFLAGS are set it will default to Release. i.e ( cmake .. ) * If a developer want full control then use export CFLAGS in leave CMAKE_BUILD_TYPE empty. * If a developer want to test CFLAGS in combination with CMAKE_BUILD_TYPE one has to specify CMAKE_BUILD_TYPE and export the CFLAG...

...ses the "empty" build, which is used in combination with the environment variables CFLAGS and CXXFLAGS. This build type is targeted at Linux distributions which want to use the same compiler flags for multiple packages. If you want to change the default build type to something else when CMAKE_BUILD_TYPE is empty, make sure that you do that when $ENV{CFLAGS} and $ENV{CXXFLAGS} are not set. There is a blog entry at Kitware https://blog.kitware.com/cmake-and-the-default-build-type/ on this topic. Unfortunately it doesn't address the CFLAGS, CXXFLAGS issue. I guess one can combine the both and h...

Willtry removing that and reinstalling 2.8. OK, I figured, I have to set CMAKE_BUILD_TYPE to Release and then everything works. With an empty CMAKE_BUILD_TYPE it doesn't work, maybe because LLVM defines _DEBUG and that confuses wxwidgets into a debug mode, and fails because wxwidgets is really built in release mode? Don't know... Best regards, --Edwin

Hi Mark, Thanks for the feedback. By default CMake is building the static library in debug, to get other things one has to explicit turn it on. To build in release mode for CMake you use the following flag: -DCMAKE_BUILD_TYPE=Release https://cmake.org/cmake/help/latest/variable/CMAKE_BUILD_TYPE.html CMAKE_BUILD_TYPE — CMake 3.14.1 Documentation<https://cmake.org/cmake/help/latest/variable/CMAKE_BUILD_TYPE.html> CMAKE_BUILD_TYPE¶. Specifies the build type on single-configuration generators. This statically specifie...

Committed a change for the cmake build that implements the option LLVM_ENABLE_ASSERTS. Defaults to ON if and only if CMAKE_BUILD_TYPE is Release. -- Óscar

Hello, I'm working on a project involving LLVM and keep shifting between the Debug and Release build by assigning different values to CMAKE_BUILD_TYPE in <llvm_build>/CMakeCache.txt and then building it. I wanted to know if this was a safe alternative to re-configuring the build after removing <llvm_build>/CMakeFiles/ and <llvm_build>/CMakeCache.txt.

I tried the new cmake-based build system to build Opus on Linux and macOS. I'm not familiar with cmake but based on instructions I found online I used it as follows: - mkdir build - cd build - cmake -DCMAKE_INSTALL_PREFIX:PATH=<install-path> .. - make - ctest - make install Although the "make" command completed, it reported that optimizations were disabled:

You're probably right, in that if I just want to build e.g. clang from source because my distro package manager contains an old version and I'm not interested in hacking on it myself, then a release build makes sense. However, I think thi...
