Gcc5 Zamiast Gcc6 W Fedorze24

[tadek]

Fedora24 przychodzi z gcc61 a ja do moich programów potrzebuję gcc53. Jak obejść tę sytuację?

[@WalDo]

Nie aktualizować? Dodaj do /etc/yum.conf linijkę

exclude=gcc*

[tadek]

skoro już mam F24 to zrobić najpierw downgrade do F23 a potem upgrade do F24 z pominięciem gcc? Jestem przekonany, że można mieć kilka wersji gcc jednocześnie chociaż mnie wystarczy 53.

[@WalDo]

No fakt, da się. Wpisz w Googla "different versions of gcc on one linux" - 1. link a potem rozdział 2.1

Wprawdzie to o starszych wersjach gcc, ale pewnie na nowszych działa równie dobrze.

Dzięki. Ja spróbowałem wg: http://www.tellurian.com.au/whitepapers/multiplegcc.php własnoręcznej kompilacji. Pomimo, że configure:

Może potrzebne są jakieś parametry?

mógłbyś rozwinąć bo ja coś nie rozumiem.

[tadek]

Zrobione. W rzeczy samej gcc54 zawiera już łatki wskazane przez sunrise. Dzięki za uwagi.
