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_DEBUG
If SPVM_CC_DEBUG environement variable is a true value of Perl, debug messages and messages from SPVM native class compiler and linker are printed to stderr.
Note that this environment variable is only effective during runtime compilation (JIT).
SPVM_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_FORCE
If SPVM_CC_FORCE environement variable is a true value of Perl, the compilation and link by SPVM native class compiler and linker are forced.
This setting has a higher priority than SPVM::Builder::Config#force 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).
