| """distutils.zosccompiler |
| |
| Contains the selection of the c & c++ compilers on z/OS. There are several |
| different c compilers on z/OS, all of them are optional, so the correct |
| one needs to be chosen based on the users input. This is compatible with |
| the following compilers: |
| |
| IBM C/C++ For Open Enterprise Languages on z/OS 2.0 |
| IBM Open XL C/C++ 1.1 for z/OS |
| IBM XL C/C++ V2.4.1 for z/OS 2.4 and 2.5 |
| IBM z/OS XL C/C++ |
