Understanding STANDARD_BINDIR_PREFIX and -B overrides
A developer seeks to understand how the `-B` flag overrides `STANDARD_BINDIR_PREFIX` in GCC to correctly locate COBOL include files.
A developer is seeking clarification on how the -B flag interacts with STANDARD_BINDIR_PREFIX in GCC, specifically in the context of compiling COBOL. They want to understand how -B overrides the default search path for executables like cobol1 and how to propagate this information to the COBOL compiler to locate include files. This is important for ensuring that the COBOL compiler can find necessary include files similar to how C++ finds <algorithm>.
In Details
The user wants to understand how STANDARD_BINDIR_PREFIX is used to locate the cobol1 executable, and how the -B option and GCC_EXEC_PREFIX environment variable modify this path. The goal is to propagate this overridden path to the COBOL compiler to locate include files.
For Context
STANDARD_BINDIR_PREFIX specifies the default location where GCC expects to find executables like compilers and linkers. The -B option allows users to override this default location, specifying a different directory to search for these executables. Understanding how these mechanisms work is crucial for developers who need to customize the build environment or use non-standard compiler locations. This is relevant when compiling languages like COBOL that rely on external executables and include files.
