Subject: [Buildroot] [PATCH 1/1] package/libheif: needs gcc >= 10
Date: Sat, 7 Mar 2026 19:54:25 +0100 [thread overview]
Message-ID: <20260307185425.729667-1-bernd@kuhls.net> (raw)
Fixes build error with gcc 9.x:
output/build/libheif-1.21.1/libheif/nclx.h:128:50: error:
'bool nclx_profile::operator==(const nclx_profile&)
const' cannot be defaulted
using this defconfig:
BR2_arm=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y
BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.org/toolchains/tarballs/br-arm-full-static-2020.11.2.tar.bz2"

# BR2_TOOLCHAIN_EXTERNAL_HAS_THREADS_DEBUG is not set
BR2_TOOLCHAIN_EXTERNAL_CXX=y
BR2_STATIC_LIBS=y
BR2_PACKAGE_LIBHEIF=y
According to https://github.com/strukturag/libheif/issues/1615#issuecomment-3457979167
gcc >= 10 with support for C++20 is needed for the package.
The failing code was introduced upstream in version 0.21.0 with commit
https://github.com/strukturag/libheif/commit/a62f933e380e165dc2c12a879d0ceed1529b3efa
which was added to buildroot with commit
a8aed698c706ec534ddc41cdce651c18016c28ca.
Also removed -std=c++11 from CXXFLAGS.
The build error was not yet recorded by the autobuilders.
