This includes arguments and environment variables like CFLAGS. The config.nice file is created by ./configure, and is super-useful as it allows to quickly re-run configure with additional arguments or modified environment variables. Environment variables are not properly pretty-printed. As a result, running the pretty-printed command doesn't give the same result as the original command. Test script: --------------- $ CFLAGS="-O0 -ggdb -Wall" ./configure --enable-debug $ cat config.nice Expected result: ---------------- #! /bin/sh # # Created by configure CFLAGS='-O0 -ggdb -Wall' \ './configure' \ '--enable-debug' \ "$@" The command is correctly pretty-printed, and running it gives the same result as the original command. Actual result: -------------- #! /bin/sh # # Created by configure CFLAGS='-O0 -ggdb -Wall' \ './configure' \ '--enable-debug' \ 'CFLAGS=-O0 \ '-ggdb' \ '-Wall'' \ "$@" Running the command results in the following error: configure: error: C compiler cannot create executables See `config.log' for more details configure: WARNING: cache variable ac_cv_env_CFLAGS_value contains a newline ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72180&edit=1
