How to install GCC-Toolset 15 in Oracle Linux 8?

Question

According to OL-PRODUCT-LIFECYCLE.pdf , Table 2-6, GCC-Toolset 15 is available in application stream of Oracle Linux 8.10 .

However, dnf install gcc-toolset-15 fails.

It can be reproduced in a docker container with Dockerfile like this:

FROM oraclelinux:8.10

RUN dnf install gcc-toolset-15

ENTRYPOINT ["/bin/bash"]

And and docker build command

docker build -t gcc-docker .

It fails to find gcc-toolset-15 with below error message. However, if I replace it with gcc-toolset-14 , it works fine.

How should I install GCC Toolset 15 to Oracle Linux 8.10 ?

Thanks.

I tried different ways but looks like 8.10 does not have gcc15 even that PDF say it is supported, maybe it is supported in the real installation(non-docker version), anyway in order to have gcc15 in docker 8.10 version you can use below docker file

FROM oraclelinux:8.10

# Install build dependencies
RUN dnf -y groupinstall "Development Tools" \
    && dnf -y install wget tar bzip2 gcc-c++ gmp-devel mpfr-devel libmpc-devel zlib-devel

# Set GCC version
ENV GCC_VERSION=15.1.0
ENV GCC_PREFIX=/opt/gcc-${GCC_VERSION}
ENV PATH=${GCC_PREFIX}/bin:$PATH

# Download and build GCC
RUN mkdir -p /tmp/gcc-src \
    && cd /tmp/gcc-src \
    && wget https://ftp.gnu.org/gnu/gcc/gcc-${GCC_VERSION}/gcc-${GCC_VERSION}.tar.gz \
    && tar -xzf gcc-${GCC_VERSION}.tar.gz \
    && cd gcc-${GCC_VERSION} \
    && ./contrib/download_prerequisites \
    && mkdir build && cd build \
    && ../configure --prefix=${GCC_PREFIX} --enable-languages=c,c++ --disable-multilib \
    && make -j$(nproc) \
    && make install \
    && cd / && rm -rf /tmp/gcc-src

# Verify installation
RUN gcc --version

ENTRYPOINT ["/bin/bash"]

after build

ozkan@ozkan-debian:~/tmp/oracletest$ docker run -it gcc-docker
[root@6ee86999623c /]# gcc --version
gcc (GCC) 15.1.0
