Bug 230449 – sci-mathematics/sympow - a package to compute special values of symmetric power elliptic curve L-functions

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description François Bissey 2008-07-02 04:39:31 UTC]

An ebuild for sympow:
"a package to compute special values of symmetric power elliptic curve L-functions".
This is sage dependency. 
Package has some obvious problems that I need to address with upstream:
*versioning of source.
*data location. The program needs to compute data and store them,
in a fixed location. Not a problem if you install it as a user. Here
I had to make a folder world writable under /usr/lib/sympow - bad.
Patching to store data in ~/.sympow by myself proved to be a bridge too
far as the code style looks like an entry to C obfuscated contest.

Reproducible: Always

Here are some comments for the ebuild:

>KEYWORDS="~x86 ~ppc ~amd64 ~ppc64"

Use only architectures where you can test them.

>S="${WORKDIR}/SYMPOW-1.019"

Use ${PV} instead of 1.019


>src_install() {
>	dodir "/usr/lib/${PN}"

Use /usr/$(get_libdir) (you need to inherit multilib)

>	cd "${S}"

Don't need it

>	cp sympow "${D}/usr/lib/${PN}/"
>	cp new_data "${D}/usr/lib/${PN}/"
>	cp *.gp "${D}/usr/lib/${PN}/"
>	cp -r datafiles "${D}/usr/lib/${PN}/"
>	chmod 0777 "${D}/usr/lib/${PN}/datafiles/"
>	chmod 0666 "${D}/usr/lib/${PN}/datafiles/param_data"

Use doins, dolib, insinto...

In sage-on-gentoo overlay

[Comment 5 Michael Orlitzky 2020-05-14 22:04:19 UTC]

I'm going to try to package the fork instead. First I'll have to figure out what to do about that weird license.

[Comment 6 François Bissey 2020-05-17 10:36:42 UTC]

Note that the current version in sage-on-gentoo (and likely in vanilla sage) is suffering badly with gcc-10. Multiple failures because of -fno-common. Would be good if the fork could deal with that too.

    sci-mathematics/sympow: new package for symmetric power L-functions.
    
    This is an actively-maintained fork of Mark Watkins's original sympow
    package (that is now impossible to find) by Debian's Jérôme Benoit.
    Sympow is a dependency of SageMath, and SageMath will soon be able to
    use the system's copy of sympow. Having this in Gentoo therefore avoids
    pointless rebuilds of sympow for Gentoo users of SageMath.

I think they already fixed it. I haven't gone digging through the commit history, but it builds with CFLAGS="-fno-common" on my gcc-9.x.

[Comment 9 François Bissey 2020-05-18 01:07:18 UTC]

Thanks, I'll check. And then I'll purge one of the foulest packages out from the sage-on-gentoo overlay. Can't wait to give the other one (jmol) the cold shoulder.

I give it the gcc-10 ready sticker :)
