If you want to use NaCl instead, set ENABLE_LIBSODIUM=OFF -* Use ENABLE_OPENSSL=ON/OFF to enable or disable compiling against OpenSSL -* If you have a toolchain without binutils plugin support (e.g. on Debian Wheezy), it is not enough to keep ENABLE_LTO disabled, in addition CMake must be told to use the standard `ar`, `ranlib` and `nm` implementation instead of the GCC-provided versions:: +* If you have a recent enough toolchain (GCC 4.8 or higher recommended), you can enable link-time optimization with ENABLE_LTO=ON to get slightly better optimized binaries +* If you want to use LTO with a binutils version without linker plugin support, you need to use the GCC versions of ar, nm and ranlib by setting the following variables:: - CMAKE_AR=/usr/bin/ar - CMAKE_RANLIB=/usr/bin/ranlib - CMAKE_NM=/usr/bin/nm + CMAKE_AR=/usr/bin/gcc-ar + CMAKE_NM=/usr/bin/gcc-nm + CMAKE_RANLIB=/usr/bin/gcc-ranlib * You can see all CMake options by calling ``ccmake .`` in the build directory after running cmake. Use the `t` key to toggle display between simple and advanced view and use `c` and then `g` to update the configuration after making changes in ccmake. |
