# Compiler settings for 64-bit AIX/powerpc using gcc and native linker
|
|
#
|
|
# Tested with AIX 6.1.0.0. Requires AIX 5.1+
|
|
#
|
|
# 2008-11-04 recommend gcc 4.3.1 or higher
|
|
#
|
|
# To compile an application in 64 bit mode, one should use the option -maix64,
|
|
# which enables the 64-bit AIX ABI such as: 64-bit pointers, 64-bit long type,
|
|
# and the infrastructure needed to support them. Specifying -maix64 implies
|
|
# -mpowerpc64 and -mpowerpc, while -maix32 disables the 64-bit ABI and implies
|
|
# -mno-powerpc64. GCC defaults to -maix32.
|
|
#
|
|
# Notes:
|
|
#
|
|
# 1) Set these variables before running autogen.sh. If you don't,
|
|
# sizeof long will be incorrectly detected as 4, not 8, by autoconf.
