OS detecting makefile. If you do not need sophisticated stuff as done by Git LSF, you can detect the Operating System just using two simple tricks environment variable OSand then the command uname sifeq OS,WindowsNT. OS Windows. detectedOS shell uname s. Or a more safe way, if not Windows and command uname not available ifeq OS,WindowsNT. OS Windows. detectedOS shell sh c uname s 2 devnull echo not. Then you can select the relevant stuff depending on detectedOS ifeq detectedOS,Windows. CFLAGS D WIN3. OS,Darwin Mac OS X. CFLAGS D OSX. OS,Linux. CFLAGS D LINUX. OS,GNU Debian GNU Hurd.

The use of OS instead of uname s simplifies the identification algorithm. You can still use solely uname s but you have to deal with ifelse blocks to check all Min. GWCygwin. variations. Note The environment variable OS is always set to WindowsNT on any Windows platform see Windows Environment Variables on Wikipedia. An alternative of OS is the environment variable MSVC it checks the presence of MS Visual Studio, see example using MSVC. Hp 2540 Printer Installing Ink Cartridges. Below I provide a complete example using make and gcc to build a shared library. The example is as simplest as possible to be more understandable To install make and gcc on Windows see Cygwin or Min. On Monday, we learned that Microsoft was killing off the iconic Microsoft Paint program after 32 years and replacing it with Paint 3D in its upcoming Windows 10 update. Does Your Computer Use EFI EFI is a type of firmware, meaning that its software built into the computer to handle lowlevel tasks. Most importantly, the firmware.

My example is based on 5 files lib. Makefile. hello. Makefile. Do not forget files Makefile are indented using tabulations. The two files Makefile. Makefileifeq OS,WindowsNT.
