Gentoo Linux Ebuild

[BioMike]

You should specify which ebuild is yours so that others know.  Currently there are two ebuild versions in the repository.

Updated the ebuild on github for version 0.3.12.

[mizerydearia]

Updated bitcoin-9999.ebuild to work with revision 155

[mizerydearia]

bitcoin-9999.ebuild tested to work with latest svn snapshot 156: http://bitcointalk.org/index.php?topic=1048.msg13219#msg13219
Also, fixed this, however, init script is still buggy/unfinished.

svn ebuild: bitcoin-9999.ebuild updated (currently revision 157)

bitcoin-0.3.13 ebuild is now available. Made some small changes in the process (bitcoin is C++, so renamed the CFLAGS to CXXFLAGS).

Have fun.

Any chance of a CUDA use flag, maybe restricted to a certain revision?

[BioMike]

As CUDA isn't in the main releases yet, I'm not going to include it (my goal is to get it as stable as possible to get it included into the main gentoo tree). Mizerydearia is taking care of the live ebuild and might want to include it.

[mizerydearia]

I do not have an nVidia gpu and cannot afford to buy anything for the foreseeable future.  If another gentoo user is willing to provide an ebuild for the CUDA client, that would be appreciated.  I can provide access to the github repository if somene is willing to contribute a CUDA ebuild.  Otherwise instead of an entirely separate ebuild, if there are patches (just like the others) that can be applied when "cuda" USEFLAG is enabled, then you're welcome to modify my ebuild as well.

I think that would be the way to go. If the patches are right you could build it with USE="cuda", but the program would just not use it. People with Cuda hardware could then test it for you.

Thanks for the replies, getting it into the main tree is indeed a lot more important. Good luck!

I will contribute a CUDA ebuild, once i get the damn makefile to work.
I guess perhaps this weekend.

What github username do you use?  I'll add commit access.

 hi,

 I m new to bitcoin and have just built bitcoin on my gentoo using your ebuild :
http://github.com/mizerydearia/bitcoin_gentoo_ebuild/tree/master

 I use gentoo for years but never had to use a custom ebuild until now, so I had to search how to use it .

 My small contribution for the next one wanted to test bitcoin on gentoo, I just did :

 First I added in make.conf :

Code:

 PORTDIR_OVERLAY=/usr/local/portage

to be able to use a custon ebuild

 Then :

Code:

emerge git # install git
git clone http://github.com/mizerydearia/bitcoin_gentoo_ebuild.git #to get the ebuild
cp -af net-p2p /usr/local/portage # put the ebuild in the overlay
emerge -pv bitcoin # check everything is ok and see the default use flags

then  in /etc/portage/package.use :

Code:

=net-p2p/bitcoin-0.3.13  nls sse2 daemon -gui

and in /etc/portage/package.keywords

Code:

=net-p2p/bitcoin-0.3.13         ~x86

 and finally build it :

Code:

emerge -pv bitcoin # check again the useflags
emerge bitcoin # build and install it

but I got :

Code:

any ideas ? did I miss something ? should I disable this sse2 ?

Clearly i can see that Your makefile is not reading the @@GENTOO_CFLAGS_SSE2@@ variable.
Another question is, WHY.

I am using exactly the same ebuild as You are and everything works.

Perhaps something is wrong with Your cflags. Check make.conf. perhaps You should add processor type/architecture to the $CFLAGS variable.

----
You can post Your make.conf here, i will take a look at it.


----
EDIT: Correction, I'm not using the same ebuild as You, I'm using its older version.
Perhaps something broke later ?

[ShadowOfHarbringer]

I think that Your cflags are wrong (too general). You need to set them for specifically Your processor type, so SSE2 will be detected and set.
But i might be wrong.

Code:

CFLAGS="-O2 -mtune=i686 -pipe"
declare -x CXXFLAGS="-O2 -mtune=i686 -pipe"

Look at mine in comparison:

Code:

CFLAGS="-march=k8 -O2 -pipe"
CXXFLAGS="-march=k8 -O2 -pipe"

Those are set specifically for AMD64 processor with SSE2 support.
Another thing is that perhaps Your processor does not support SSE2 ?

You could post Your hardware specs.

Also, here are lists for safe Gentoo CFLAGS for every Intel/AMD processor:

[neofutur]

my CPU is :

model name     : Intel(R) Core(TM)2 Duo CPU     E6550  @ 2.33GHz
flags   : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe lm constant_tsc arch_perfmon pebs bts pni monitor ds_cpl vmx smx est tm2 ssse3 cx16 xtpr lahf_lm

should have this sse2 support according to the flags

EDIT :

 same problem after changing my CFLAGS  ;(

 I tried :

CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer"

and

CFLAGS="-O2 -march=native -pipe -fomit-frame-pointer"

[ShadowOfHarbringer]

I think You should ask this question at Gentoo Forums as it seems that Your Gentoo is misconfigured somehow.

They will know why is Your SSE2 variable not set.

BTW,
Did You do $ env-update && source /etc/profile as root after changing your CFLAGS ?
Alternatively, You may restart Your computer - that should work too.

[ShadowOfHarbringer]

Never mind my previous post.

I've studied the code of the ebuild and i know what the @@GENTOO_CFLAGS_SSE2@@ is.

This "@@GENTOO_CFLAGS_SSE2@@" gets replaced by "-DFOURWAYSSE2" by emerge, which is defined in the ebuild. If it is not replaced, something wrong is going on with the ebuild.

My advice: try the older version (as it worked for me).

[BioMike]

I see my Makefile.gentoo got reverted to an older version, caused by an update by mizerydearea. That is causing the problem.

I'll see if I can get my version in again.

<edit>Corrected Makefile.gentoo is in github again</edit>
