 Posted: Sun Mar 11, 2007 4:03 pm Post subject: Cos'è questa USE="d" nelle gcc? |
 |
|
Ho da poco fatto un sync e mi trovo le gcc da ricompilare con una nuova USE="d". La cosa mi puzza un pò...questa è la situazione:
| Code: | jarod ~ # emerge -pv gcc
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] sys-devel/gcc-4.1.2 USE="fortran gtk nls (-altivec) -bootstrap -build -d% -doc -gcj (-hardened) -ip28 -ip32r10k -mudflap (-multilib) -multislot (-n32) (-n64) -nocxx -objc -objc++ -objc-gc -test -vanilla" 0 kB
Total: 1 package (1 reinstall), Size of downloads: 0 kB |
Ma con equery la USE="d" sembra non esistere:
| Code: | jarod ~ # equery uses gcc
[ Searching for packages matching gcc... ]
[ Colour Code : set unset ]
[ Legend : Left column (U) - USE flags from make.conf ]
[ : Right column (I) - USE flags packages was installed with ]
[ Found these USE variables for sys-devel/gcc-4.1.2 ]
U I
- - altivec : Adds support for optimizations for G4 and G5/ppc970 processors
- - bootstrap : !!internal use only!! DO NOT SET THIS FLAG YOURSELF!, used during original system bootstrapping [make stage2]
- - build : !!internal use only!! DO NOT SET THIS FLAG YOURSELF!, used for creating build images and the first half of bootstrapping [make stage1]
- - doc : Adds extra documentation (API, Javadoc, etc)
+ + fortran : Adds support for fortran (formally f77)
- - gcj : Enable building with gcj (The GNU Compiler for the Javatm Programming Language)
+ + gtk : Adds support for x11-libs/gtk+ (The GIMP Toolkit)
- - hardened : activate default security enhancements for toolchain (gcc, glibc, binutils)
- - ip28 : Enable building a compiler capable of building a kernel for SGI Indigo2 Impact R10000 (IP28)
- - ip32r10k : Enable building a compiler capable of building an experimental kernel for SGI O2 w/ R1x000 CPUs (IP32)
- - mudflap : Add support for mudflap, a pointer use checking library
- - multilib : On 64bit systems, if you want to be able to compile 32bit and 64bit binaries
- - multislot : Allow for SLOTs to include minor version (3.3.4 instead of just 3.3)
- - n32 : Enable n32 ABI support on mips
- - n64 : Enable n64 ABI support on mips
+ + nls : Adds Native Language Support (using gettext - GNU locale utilities)
- - nocxx : Disable support for C++ (DON'T USE THIS UNLESS YOU KNOW WHAT YOU'RE DOING)
- - objc : Build support for the Objective C code language
- - objc++ : Build support for the Objective C++ language
- - objc-gc : Build support for the Objective C code language Garbage Collector
- - test : Workaround to pull in packages needed to run with FEATURES=maketest / FEATURES=test
- - vanilla : Do not add extra patches which change default behaviour; DO NOT USE THIS ON A GLOBAL SCALE as the severity of the meaning changes drastically |
ecco qualche info:

Credo che non si tratti di un errore, ecco cosa dice il ChangeLog:
| ChangeLog gcc wrote: | 09 Mar 2007; Mike Frysinger <vapier@gentoo.org> gcc-3.4.6-r2.ebuild,
gcc-4.1.2.ebuild:
Add support for version 0.23 of the D language addon.
|
Questo invece lo riporta "euse -i d":
| Code: | local use flags (searching: d)
************************************************************
[- ] d (sys-devel/gcc):
Enable support for the D programming language
|
Se ti serve il linguaggio D, molto probabilmente no, tienila disabilitata, altrimenti attivala.

Per conferma basta leggere il commento in /usr/portage/eclass/toolchain.eclass che viene ereditata da GCC:
| Code: |
if use d ; then
ebegin "Adding support for the D language"
./gcc/d/setup-gcc.sh >& "${T}"/dgcc.log
if ! eend $? ; then
eerror "The D gcc package failed to apply"
eerror "Please include this log file when posting a bug report:"
eerror " ${T}/dgcc.log"
die "failed to include the D language"

Succo del discorso, che voglia o non voglia il supporto a questo linguaggio D, le gcc me le devo ricompilare di nuovo:
| Code: | jarod ~ # USE="d" emerge -pv gcc
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] sys-devel/gcc-4.1.2 USE="d%* fortran gtk nls (-altivec) -bootstrap -build -doc -gcj (-hardened) -ip28 -ip32r10k -mudflap (-multilib) -multislot (-n32) (-n64) -nocxx -objc -objc++ -objc-gc -test -vanilla" 932 kB
Total: 1 package (1 reinstall), Size of downloads: 932 kB |
| Code: | jarod ~ # USE="-d" emerge -pv gcc

Uff...

Beh, nessuno ti obbliga a usare --newuse

Per come la vedo io quell'opzione dovrebbe partire automaticamente ad ogni emerge, senza bisogno di aggiungerla a manina
ps: ora vado a cercare quando esce una nuova versione delle gcc, non si sa mai che oggi mi metto a compilarle e tra un paio di giorni dopo un sync...

Beh, se scegli di utilizzare tutto il sistema in testing devi aspettarti upgrade frequenti, è normale.

@Luca89: Guarda che il "D" è in stabile sul 3.4.6 (accidenti doppio e triplo accidenti!  ) quindi non ti capitano solo in ~ certe scocciature.
@lucapost: lo so che è un tantino brutale e bestiale (nel senso di azione ferina e disdicevole... da cavernicolo) farlo... ma aggiungere "d" in /var/db/pkg/sys-devel/gcc-vattelappesca/IUSE?
Tanto non mi pare che ci siano enormi differenze tra il vecchio ed il nuovo ebuild (ho la hardened quindi non uso il gcc-4.x)

Luca89 si riferiva al fatto che su ~ ci sono upgrade frequenti, non che la USE "d" sia stata aggiunta solo in gcc-4.1.2.
Rileggiti bene gli ultimi post

uhm... ho rieditato il post, il commento era acido ma nei confronti dell'aggiunta del "D" (però scritto così pareva più un "che cavolo stai dicendo?!") anche sulle stabili, quindi non capita solo a chi usa instabile.
Qualche volta mi rendo conto che dovrei tornare a squola ad impararmi più meglio l'italiano
