如何使用 gcc 5.5 在 gdal 2.4 中启用 c++14

这里的帮助配置：

./configure --help
`configure' configures this package to adapt to many kinds of systems.
Usage: ./configure [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help              display this help and exit
--help=short        display options specific to this package
--help=recursive    display the short help of all the included packages
-V, --version           display version information and exit
-q, --quiet, --silent   do not print `checking ...' messages
--cache-file=FILE   cache test results in FILE [disabled]
-C, --config-cache      alias for `--cache-file=config.cache'
-n, --no-create         do not create output files
--srcdir=DIR        find the sources in DIR [configure dir or `..']
Installation directories:
--prefix=PREFIX         install architecture-independent files in PREFIX
[/usr/local]
--exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
[PREFIX]
By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc.  You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR            user executables [EPREFIX/bin]

Some influential environment variables:
CC          C compiler command
CFLAGS      C compiler flags
LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS        libraries to pass to the linker, e.g. -l<library>
CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
CXX         C++ compiler command
CXXFLAGS    C++ compiler flags
LT_SYS_LIBRARY_PATH
User-defined run-time library search path.
CPP         C preprocessor
CXXCPP      C++ preprocessor
PKG_CONFIG  path to pkg-config utility
OGDI_CFLAGS C compiler flags for OGDI, overriding pkg-config
OGDI_LIBS   linker flags for OGDI, overriding pkg-config
HDF5_CFLAGS C compiler flags for HDF5, overriding pkg-config
HDF5_LIBS   linker flags for HDF5, overriding pkg-config
OPENJPEG_CFLAGS
C compiler flags for OPENJPEG, overriding pkg-config
OPENJPEG_LIBS
linker flags for OPENJPEG, overriding pkg-config
LIBKML_CFLAGS
C compiler flags for LIBKML, overriding pkg-config
LIBKML_LIBS linker flags for LIBKML, overriding pkg-config

C compiler flags for POPPLER, overriding pkg-config
POPPLER_LIBS
linker flags for POPPLER, overriding pkg-config
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
Report bugs to the package provider.

所以你是对的，这样做后我得到了

C++ compiler:              g++ -std=c++14 -DHAVE_AVX_AT_COMPILE_TIME -DHAVE_SSSE3_AT_COMPILE_TIME -DHAVE_SSE_AT_COMPILE_TIME -g -O2
C++14 support:             yes

我不习惯使用 ./configure 进行编译，我不知道可以使用 --help... 感谢您的帮助！
