Detailed Description

This is a wrapper for the QNX C/C++ compiler, QCC.

QCC is a command line front end that invokes GCC under the hood, so we derive the behaviour from the GCC wrapper.

Member Function Documentation

can_handle_command()

bool bcache::qcc_wrapper_t::can_handle_command ( )

overridevirtual

Check if this class implements a wrapper for the given command.

Returns

true if this wrapper can handle the command.

Reimplemented from bcache::gcc_wrapper_t.

get_build_files()

std::map< std::string, expected_file_t > bcache::qcc_wrapper_t::get_build_files ( )

overrideprivatevirtual

Get the paths to the files that are to be generated by the command.

Returns

the files that are expected to be generated by this command.

Exceptions

runtime_error

if the request could not be completed.

Reimplemented from bcache::gcc_wrapper_t.

get_capabilities()

string_list_t bcache::qcc_wrapper_t::get_capabilities ( )

overrideprivatevirtual

Generate a list of supported capabilites.

The list of capabilites can contain zero or more of the following (case sensitive) strings:

String	Meaning
create_target_dirs	Request creation of missing output dirs
direct_mode	Supports direct mode
hard_links	Can use hard links for cached files

In order to support direct mode, get_input_files() and get_implicit_input_files() need to be implemented.

Returns

a list of supported capabilites.

Exceptions

runtime_error

if the request could not be completed.

Note

Capabilites are "opt-in". If this method is not implemented or returns an empty list, all capabilites will be treated as "not supported".

Reimplemented from bcache::gcc_wrapper_t.

get_program_id()

std::string bcache::qcc_wrapper_t::get_program_id ( )

overrideprivatevirtual

Get a string that uniquely identifies the program.

Returns

a program ID string.

Exceptions

runtime_error

if the request could not be completed.

Reimplemented from bcache::gcc_wrapper_t.

get_relevant_env_vars()

std::map< std::string, std::string > bcache::qcc_wrapper_t::get_relevant_env_vars ( )

overrideprivatevirtual

Get relevant environment variables for hashing.

Returns

relevant environment variables and their values.

Exceptions

runtime_error

if the request could not be completed.

Note

The purpose of this function is to create a list of environment variables that may affect program output.

Reimplemented from bcache::gcc_wrapper_t.
