* Switch to static libraries by default and ensure application rebuild when a ↵Pavel Pisa2019-03-15
| | | | | | | | | | | | | | | | library changes. I have not found a way how to pass additional CONFIG options to Debian package build (dpkg-buildpackage) when qmake is invoked from debian/rules with debian helper based (dh) build. The way how qmake solves dependencies between program and libraries comes from stone age. It is necessary to include complete path to the library in PRE_TARGETDEPS definition including lib prefix and .a suffix. This is non portable and cannot be easily used when static and dynamic libraries build alternatives are considered. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>

| | | | | | | | | | | option. When operating system emulation root directory (fs_root) are selected then open() syscall opens real host system files in this limited subtree. When fs_root is not set then console is mapped to all read, write, open and close calls. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
