3: # This Makefile fragment implements handling for supported C/C++/Fortran
4: # compilers.
1.8 grant 5: #
1.26 jlam 6: # The following variables are used by this file:
1.1 grant 7: #
1.26 jlam 8: # PKGSRC_COMPILER
9: # A list of values specifying the chain of compilers to be used by
10: # pkgsrc to build packages.
11: #
12: # Valid values are:
13: # distcc distributed C/C++ (chainable)
14: # ccache compiler cache (chainable)
15: # gcc GNU
16: # mipspro Silicon Graphics, Inc. MIPSpro (n32/n64)
17: # mipspro-ucode Silicon Graphics, Inc. MIPSpro (o32)
18: # sunpro Sun Microsystems, Inc. WorkShip/Forte/Sun
19: # ONE Studio
20: #
21: # The default is "gcc". You can use ccache and/or distcc with an
22: # appropriate PKGSRC_COMPILER setting, e.g. "ccache distcc gcc".
23: # The chain should always end in a real compiler. This should only
24: # be set in /etc/mk.conf.
1.1 grant 25: #
1.7 grant 26: # GCC_REQD
1.26 jlam 27: # A list of version numbers used to determine the minimum
28: # version of GCC required by a package. This value should only
29: # be appended to by a package Makefile.
1.7 grant 30: #
1.26 jlam 31: # NOTE: Be conservative when setting GCC_REQD, as lang/gcc3 is
32: # known not to build on some platforms, e.g. Darwin. If gcc3 is
1.7 grant 33: # required, set GCC_REQD=3.0 so that we do not try to pull in
34: # lang/gcc3 unnecessarily and have it fail.
35: #
1.26 jlam 36: # USE_PKGSRC_GCC
37: # Force using the appropriate version of GCC from pkgsrc based on
38: # GCC_REQD instead of the native compiler.
39: #
1.7 grant 40: # USE_GCC_SHLIB
41: # Indicates that a package uses GCC shared libraries, so we
42: # register a runtime dependency on the compiler package.
43: #
1.26 jlam 44: # USE_LANGUAGES
45: # Lists the languages used in the source code of the package,
46: # and is used to determine the correct compilers to install.
47: # Valid values are: c, c++, fortran, java, objc. The default
48: # is "c".
