add support for build system overlays that alter package build instructions

[openwrt.git] / package / wpa_supplicant / config

# Example wpa_supplicant build time configuration
#
# This file lists the configuration options that are used when building the
# hostapd binary. All lines starting with # are ignored. Configuration option
# lines must be commented out complete, if they are not to be included, i.e.,
# just setting VARIABLE=n is not disabling that variable.
#
# This file is included in Makefile, so variables like CFLAGS and LIBS can also
# be modified from here. In most cases, these lines should use += in order not
# to override previous values of the variables.


# Uncomment following two lines and fix the paths if you have installed OpenSSL
# or GnuTLS in non-default location
#CFLAGS += -I/usr/local/openssl/include
#LIBS += -L/usr/local/openssl/lib

# Some Red Hat versions seem to include kerberos header files from OpenSSL, but
# the kerberos files are not in the default include path. Following line can be
# used to fix build issues on such systems (krb5.h not found).
#CFLAGS += -I/usr/include/kerberos

# Example configuration for various cross-compilation platforms

#CONFIG_NO_WPA2=y

# Remove IEEE 802.11i/WPA-Personal ASCII passphrase support
# This option can be used to reduce code size by removing support for

# apply for distribution of the resulting binary.
#CONFIG_GNUTLS_EXTRA=y

# If CONFIG_TLS=internal is used, additional library and include paths are

# Add support for loading EAP methods dynamically as shared libraries.
# When this option is enabled, each EAP method can be either included
# statically (CONFIG_EAP_<method>=y) or dynamically (CONFIG_EAP_<method>=dyn).
# Dynamic EAP methods are build as shared objects (eap_*.so) and they need to
# be loaded in the beginning of the wpa_supplicant configuration file
# (see load_dynamic_eap parameter in the example file) before being used in
# the network blocks.
#
# Note that some shared parts of EAP methods are included in the main program
# and in order to be able to use dynamic EAP methods using these parts, the
# main program must have been build with the EAP method enabled (=y or =dyn).
# This means that EAP-TLS/PEAP/TTLS/FAST cannot be added as dynamic libraries
# unless at least one of them was included in the main build to force inclusion
# of the shared code. Similarly, at least one of EAP-SIM/AKA must be included
# in the main build to be able to load these methods dynamically.
#
# Please also note that using dynamic libraries will increase the total binary
# size. Thus, it may not be the best option for targets that have limited
# amount of memory/flash.
#CONFIG_DYNAMIC_EAP_METHODS=y

# Include client MLME (management frame processing).
# This can be used to move MLME processing of Linux mac80211 stack into user
