apt install gcc-8 doesn't seem to find anything, nor apt install gcc-8-base

gcc-8 is in Debian Buster. Debian 11 has gcc-10.

Hello pal ,

Please do not try to , I have been having a nightmare. Just use gcc-10 and/or the g++-10 that comes along with it.

gcc-10-base comes with bullseye.

"gcc" is a metapackage that depends on the release's default gcc version, gcc-10 in Bullseye's case. Some releases may have one default version, yet several other versions are in the repo. Sid just moved to gcc-11 as default, for example, yet that causes build failures at present for Pale Moon. But I can tell Pale Moon to use gcc-10 (still in Sid) if it does detect that it's building on Sid or Ubuntu 21.10 Impish:

Code: Select all

# Build with gcc-10 on releases where default gcc is 11
distrelease := $(shell lsb_release -cs)
ifeq ($(distrelease),$(filter $(distrelease),sid impish))
export CC=gcc-10
export CXX=g++-10
export CPP=cpp-10
export LD=gcc-10
endif
