| # Generic script to build (without root access) any version of emacs from git. | ||
|
|
||
| # Example usages: | ||
| # ./mybuild.sh -- Install from ${emacs_rev} | ||
| # ./mybuild.sh --quick -- Do not do 'make bootstrap' from ${emacs_rev} | ||
| # ./mybuild.sh --noopt -- Build without optimization (to allow gdb debug) from ${emacs_rev} | ||
| # ./mybuild.sh --noopt --rev origin/master -- Build without optimization (to allow gdb debug) using the master branch | ||
|
|
||
| # ./mybuild.sh --rev <COMMIT_HASH> --quick --subdir test -- Quick build for specified commit to "test/" | ||
| # ./mybuild.sh --noupdate --debug -- Only show the git info of last build | ||
| # ./mybuild.sh --rev origin/emacs-24 | ||
| # ./mybuild.sh --debug -- Do not do the actual install, but update from git | ||
| # print useful echo statements and retain the internal | ||
| # variables. | ||
| # ./mybuild.sh --subdir test -- Install in test/ dir | ||
| # ./mybuild.sh --noupdate -- Install without updating from the git | ||
| # ./mybuild.sh --noinstall -- Build but do not install in ${MY_EMACS_INSTALL_DIR} | ||
| # ./mybuild.sh --noopt --subdir noimagemagick -- Build without optimization to a subdir "noimagemagick/" | ||
| # ./mybuild.sh --noupdate --quick --noinfo --noelc --noinstall -- Quick builds without git clone, no info or elc building and no install; useful during git bisects | ||
|
|
||
| # Update the following environment variables post-installation: | ||
| # prepend PATH with "${HOME}/usr_local/apps/${OSREV}/emacs/`basename ${MY_EMACS_INSTALL_DIR}`/bin" | ||

| # --prefix for building libraries locally when the default library | ||
| # does not exist or is older than the requirements. | ||
