Posted: Tue Nov 28, 2017 4:34 pm Post subject: [SOLVED] problema di installazione sci-libs/fftw-3.3.6_p2 |
|
|
Buongiorno,
dopo qualche annetto e un po di arruginimento ho ripreso gentoo... ultimamente mi trovo in difficoltà con fftw... mi da sempre errore di compilazione ed esce dal'installazione.
ho provato a patchare... ma nulla... e non riesco nemmeno a capire chi lo voglia sto pacchetto che purtroppo mi costrignge ad ogni update allo --skipfirst.
any idea?

Code: | #error "compiling simd-avx2.h without avx2 support" |
Le flags del pacchetto sono (nel mio caso):
Code: | # equery u fftw
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for sci-libs/fftw-3.3.6_p2:
U I
+ + abi_x86_32 : 32-bit (x86) libraries
+ - cpu_flags_x86_avx : Adds support for Advanced Vector Extensions instructions
+ - cpu_flags_x86_avx2 : Adds support for Advanced Vector Extensions 2 instructions
- - cpu_flags_x86_fma3 : Use the Fused Multiply Add 3 instruction set ([fma] in cpuinfo)
- - cpu_flags_x86_fma4 : Use the Fused Multiply Add 4 instruction set
- + cpu_flags_x86_sse : Use the SSE instruction set
+ + cpu_flags_x86_sse2 : Use the SSE2 instruction set
- - doc : Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
+ + fortran : Add support for fortran
- - mpi : Add MPI (Message Passing Interface) layer to the apps that support it
+ + openmp : Build support for the OpenMP (support parallel computing), requires >=sys-devel/gcc-4.2 built with USE="openmp"
- - quad : Build quadruple precision lib
- - static-libs : Build static versions of dynamic libraries as well
- - test : Workaround to pull in packages needed to run with FEATURES=test. Portage-2.1.2 handles this internally, so don't set it in
make.conf/package.use anymore
+ + threads : Add threads support for various packages. Usually pthreads
|
disabilita la flag interessata dal pacchetto (probabilmente la tua cpu non supporta l'istruzione avx2)
Code: | # euse -D avx2 -p sci-libs/fftw |
ti suggerisco l'installazione di
Code: | # emerge app-portage/cpuid2cpuflags --ask |
in pratica rileva le flags della cpu e le abilita/disabilita nel caso vengano richieste da qualche pacchetto
Esempio
Code: | # cpuid2cpuflags
CPU_FLAGS_X86: aes avx f16c mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3 |
e le aggiungi al make.conf
Esempio :
Code: | CPU_FLAGS_X86="sse2 avx avx2 sse4_1 sse4_2" |
Ovviamente adatta il risultato con il tuo output
Code: | # emerge sci-libs/fftw --ask |

Puoi postare il tuo make.conf?

sabayonino,
in realtà io ho usato
Code: | cpuinfo2cpuflags-x86
CPU_FLAGS_X86="aes avx avx2 fma3 mmx mmxext pclmul popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3" |
e avx2 è supportato provo ad istallarlo senza....
ho tolto da CPU_FLAGS_X86= avx2 e l'installazione la fa...
ora... è possibile installare solo questo pacchetto senza avx2? euse non è utile allo scopo _________________ linux user #493115 |

l'ho scritto sopra
Code: | # euse -D avx2 -p sci-libs/fftw |
per disabilitare avx2 solo per il pacchetto e non globalmente
riabilita avx2 in cpuflags , a certe applicazioni multimediali potrebbe far comodo _________________ LRS i586 on G.Drive

avx2 non credo sia una USE ...
il comando sopra infatti restituisce :
Code: | ERROR: USE flag "avx2" does not exist |
mentre
non restitusci alcun risultato...
ci riusciremo! _________________ linux user #493115 |

cavolo è vero. mi è rimasta la USE dai tempi antichi quando le flags cpu venivano inserite in USE
allora basta toglierle dalla variabile CPU_
mi sa che devo fare un pà di pulizia

si lo avevo messo per leggibilità qui ma così nella realtà non funzionerebbe...
esiste un modo per togliere un una cpu flag solo per un pacchetto? tipo: Code: | euse -D USE mio/pacchetto | per intenderci
scusate l'orario

Si io faccio solitamente manualmente
Code: | # echo "mio/pacchetto -cpu_flags_x86_avx2" >> /etc/portage/package.use |
CPU_FLAGS_X86 e' una use expand quindi per togliere una di queste basta mettere il nome della variabile in piccolo e poi quella che vuoi togliere separata da il carattere '_' _________________ Questions are guaranteed in life; Answers aren't. |
