Portable (semi-static) Build | |||||
---------------------------- | |||||
If TigerVNC is built using GCC (including MinGW), then it may depend on the | |||||
libgcc or libstdc++ dynamic libraries. To eliminate this dependency, add | |||||
TigerVNC can under favourble circumstances be built in a way that allows | |||||
the resulting binaries to run on any system without having to also install | |||||
all the dynamic libraries it depends on. Enable this mode by adding: | |||||
-DBUILD_STATIC=1 | -DBUILD_STATIC=1 | ||||
to the CMake command line. | to the CMake command line. | ||||
Note that the method used to achieve this is very fragile and it may be | |||||
necessary to tweak cmake/StaticBuild.cmake to make things work on your | |||||
specific system. | |||||
