| Summary | 0000373: make should allow dash in macro names | ||||
| Description | The current standard specifically excludes - from portable make macro names; however, existing implementation practice shows that pretty much all vendors support this as an extension. Dash is the only character in the portable filename character set that is missing from the list of valid macro names, and adding this extension allows some additional flexibility in constructing macro names based on file names. See for example this survey: http://lists.gnu.org/archive/html/bug-autoconf/2011-01/msg00036.html > dashes in > - GNU make, > - dmake 4.12, > - smake 1.2.1, > - the vendor 'make' in > - MacOS X, > - FreeBSD 6.4, > - OpenBSD 4.4, > - NetBSD 5.0, > - AIX 5.1, > - HP-UX 10.20, > - IRIX 6.5 (also pmake, smake), > - OSF/1 5.1, > - Solaris 2.6 (also dmake), > and found that all support it. The test was this Makefile: > > ================== Makefile =================== > FOO-BAR = yellow_dog > FOO_BAR = green_cat > > all : $(FOO-BAR) > > $(FOO-BAR) : greet_dog > > $(FOO_BAR) : greet_cat > > greet_dog: > echo hello my dog > > greet_cat: > echo hello my cat > ================================================ | ||||
| Desired Action | At line 95787 [XCU make EXTENDED DESCRIPTION - Macros], change: "solely of periods, underscores, digits, and alphabetics from the portable character set" to: "solely of characters from the portable filename character set" | ||||

|
Concerns were raised on the 3 Feb 2011 conference as to whether leading period, dash, or digits are portable; a further sentence may be needed to restrict macro names to start with a letter or underscore. |
|
|
gmake and bsd make do support leading period, dash, and digit. |
|
|
SunPro make, smake and gmake even support dashes as first char of a macro name, but this does not seem to be important. More important would be to make macro names like "C++" valid in POSIX. |
