SPVM::Document::EnvironmentVariables - Environment Variables
Description
This document explains environment variables.
Environment Variables
If an environment variable is an empty string, it is treated as an undefined value.
SPVM_BUILD_DIR
A directory for files generated by the compiler and linker.
C source codes for precompilation, dynamic link libraries and object files are stored into this directory.
These files are output when attempting to build a module containing methods with the native attribute or the precompile attribute.
If the SPVM_BUILD_DIR environment variable is defined, these files are output to the directory. If the directory does not exist, an exception is thrown.
If the SPVM_BUILD_DIR environment variable is not defined, a temporary directory is created at the beginning of the program, and the path is set to the environment variable.
Examples:
# bash
export SPVM_BUILD_DIR=~/.spvm_build
# csh
setenv SPVM_BUILD_DIR ~/.spvm_buildSPVM_CC_QUIET
If SPVM_CC_QUIET environement variable is a true value of Perl, messages SPVM native class compiler and linker are not printed to stderr.
If it is defined and a false value of Perl, the messages are printed.
This setting has a higher priority than SPVM::Builder::Config#quiet field.
Note that this environment variable is only effective during runtime compilation (JIT).
SPVM_CC_OPTIMIZE
If SPVM_CC_OPTIMIZE environment variable is defined, the optimize field is overwritten by this value.
This setting has a higher priority than SPVM::Builder::Config#optimize field.
Note that this environment variable is only effective during runtime compilation (JIT).
