useful for me and possibly for you, too.
As of 2023, all scripts found in this repository are obsolete (probably except for Python2 stuff). Use ungoogled chromium ebuild, and official ebuilds. Don't forget to set use flag -cpudetection when building GMP. See note below on fight over GMP ebuild.
Reason for creating gmpy2-...ebuild: official .ebuild is dated (hard to use that gmpy2 from Cython).
Reason for creating gmp-...ebuild: official .ebuild installs crippled library (without microarch optimization).
In 2015 my patch to un-cripple gmp ebuild was rejected by Gentoo developers without explanation. Bug filed by me was closed with no comment with resolution won't fix. The problem of crippled GMP was stated before in 2008. It was fixed in 2022 with gmp-6.3.0.ebuild. Now GMP installs properly optimized library when use flag -cpudetection is set (at least on AMD64 platform). It took three bug reports, at least one forum discussion and 14 years to convince Gentoo folks.
Reason for messing up with iridium-browser: want a fast browser that does not segfault as often as Firefox and does not phone home as often as Chromium.
Reason for modifying telegram-desktop...ebuild: original did not work for me.
Supposing all pre-requisites met, the fastest way to compile/install software is to call ebuild directly.
- Put .ebuild close to its ancestor:
cp gmp-6.2.1-r99.ebuild /usr/portage/dev-libs/gmp/
- Run
ebuildscript:
ebuild --skip-manifest /usr/portage/dev-libs/gmp/gmp-6.2.1-r99.ebuild clean install qmerge
ebuild ... install installs compiled files into a temporary directory such as /tmp/portage/dev-libs/gmp-6.2.1-r99/image.
ebuild ... install qmerge installs compiled files into a temp directory and their final destination such as /usr/lib64.
Don't forget to clean /tmp/portage (or whatever your portage scratch dir is).
Current status of iridium-browser...ebuild: compiles with settings
L10N=en-GB CFLAGS='-O2 -march=sandybridge' USE='-component-build -cups -custom-cflags -gnome-keyring -hangouts -jumbo-build -kerberos -proprietary-codecs -pulseaudio -suid -system-ffmpeg -system-icu -system-libvpx -tcmalloc -widevine'
, does not install due to file collisions with chromium.
