Bug 18052 – Wish: USE flags for ada, f77, and objc

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Norberto Bensa 2003-03-23 14:15:05 UTC]

Hello, 
 
I'd like to compile _only_ the languages I'll use, i.e., c and c++. I've never seen ada, 
f77, nor objc so building those compilers is a waste of time in my case. I'd like to see 
use flags for ada, f77, and objc. 
 
Thanks for reading, 
Norberto

src_compile() {
        local myconf=""
        local gcc_lang=""

        if [ -z "`use build`" ]
        then
                myconf="${myconf} --enable-shared"
                gcc_lang="c,c++"

                [ -n "`use noada`" ]  || gcc_lang="${gcc_lang},ada"
                [ -n "`use nof77`" ]  || gcc_lang="${gcc_lang},f77"
                [ -n "`use noobjc`" ] || gcc_lang="${gcc_lang},objc"
                [ -n "`use java`" ] && gcc_lang="${gcc_lang},java"
        else
                gcc_lang="c"
        fi
        if [ -z "`use nls`" ] || [ "`use build`" ]
        then
                myconf="${myconf} --disable-nls"
        else
                myconf="${myconf} --enable-nls --without-included-gettext"
        fi

The USE variable should disable the languages, in order to maintain compatibility.

I support the wish to remove support for Fortran77 and ObjC by a USE flag
if they are not needed (ada seems to be gone anyway).
I'd also like to see a spearate USE flag for gcj. Activating it through java
seems strange since that's about hava a jdk or jre installed IMO. Gcj on
the other hand is something that few people will have any use of so far,
since it doesn't compile most programs yet.
