| # Make a shared library. |
| # Basically do a switch/case depending on the OS and make a shared |
| # lib conforming to that OS. |
| |
| |
| # Usage: |
| # mklib [options] objects ... |
| # Options: |
| # -o LIBRARY specifies the name of resulting library ("GL" for example) |
| # -major N specifies major version number (default is 1) |
| # -minor N specifies minor version number (default is 0) |
| # -patch N specifies patch version number (default is 0) |
| # -lLIBRARY specifies a dependency on LIBRARY |
| # -LDIR search in DIR for library dependencies |
| # -cplusplus link with C++ runtime |
| # -static make a static library (default is dynamic/shared) |
| # -install DIR move resulting library files to DIR |
| # -arch ARCH override using `uname` to determine architecture |
| # -archopt OPT specify an extra achitecture-specific option OPT |
| # |
| # The library name should just be "GL" or "GLU", etc. The 'lib' prefix |
| # will be added here if needed, as well as the ".so" or ".a" suffix, etc. |
| # |
| # objects should be: foo.o bar.o etc.o |
| # |
| # Environment variables recognized: |
| # CC C compiler command |
| # CXX C++ compiler command |
| # |
| |
| |
| # |
| # Option defaults |
