DragonFly has two compilers in base, GCC 4.4.7 and GCC 4.7.2. The way one switches between them for userland programs is to set CCVER in the environment. However, to set this via make.conf is tricky. I've been using the low level "ALL_ENV+= CCVER=gcc47", but this trick fails to properly identify the compiler which results in _GCC_VERSION being incorrectly defined. Additionally, there are some prominent packages that do not build on gcc 4.7 and the fix is either not fully understood or would require a large amount of work to implement. In these cases, it is desireable to specify the package be built on gcc 4.4 regardless of CCVER setting. To address these issues, a new directive is added: DRAGONFLY_CCVER. It is only effective if OPSYS equals "DragonFly", and it will properly set CCVER and properly define _GCC_VERSION. It will also allow a per package specification of a particular compiler in the pkg makefile.

# This Makefile fragment implements handling for supported C/C++/Fortran

# compilers.
|
|
#
|
|
# The following variables may be set by the pkgsrc user in mk.conf:
|
|
#
|
|
# PKGSRC_COMPILER
|
|
# A list of values specifying the chain of compilers to be used by
|
|
# pkgsrc to build packages.
|
|
#
|
|
# Valid values are:
|
|
# ccc Compaq C Compilers (Tru64)
|
|
# ccache compiler cache (chainable)
|
|
# clang Clang C and Objective-C compiler
|
|
# distcc distributed C/C++ (chainable)

# ONE Studio
|

# xlc IBM's XL C/C++ compiler suite (Darwin/MacOSX)
|

|
|
# The default is "gcc". You can use ccache and/or distcc with
|
|
# an appropriate PKGSRC_COMPILER setting, e.g. "ccache distcc
|
|
# gcc". You can also use "f2c" to overlay the lang/f2c package
|
|
# over the C compiler instead of using the system Fortran
|
|
# compiler. The chain should always end in a real compiler.
|
|
# This should only be set in /etc/mk.conf.

#
|
|
# COMPILER_USE_SYMLINKS
|
|
# If set to yes, use symlinks for the compiler drivers, otherwise
|

# shell scripts are created. The default is yes.
|

# The following variables may be set by a package:
|
|
#
|
|
# USE_LANGUAGES
|
|
# Lists the languages used in the source code of the package,
|
|
# and is used to determine the correct compilers to install.
|
|
# Valid values are: c, c99, c++, fortran, fortran77, java, objc,
|
|
# obj-c++, and ada. The default is "c".
