Compile GCC ​

Tested on version 6.5.0

Prerequisites ​

  • MPC
  • MPFR
  • GMP

Install GMP ​

Get source code ​

then

bash
./configure --prefix=<CLONE_DIR>/install
make -j$(nproc)
make check
make install

You can wrap the output install folder into a rez package by creating a package.py file with the following content:

python
name = "gmp"
version = "<your_version_here>"

def commands():
    env.LD_LIBRARY_PATH.prepend("{root}/install/lib")

Install MPFR ​

Get source code ​

then

bash
./configure --prefix=<CLONE_DIR>/install --with-gmp=<CLONE_DIR>/install
make -j$(nproc)
make check
make install

You can wrap the output install folder into a rez package by creating a package.py file with the following content:

python
name = "mpfr"
version = "<your_version_here>"

def commands():
    env.LD_LIBRARY_PATH.prepend("{root}/install/lib")

Install MPC ​

Get source code ​

then

bash
./configure --prefix=<CLONE_DIR>/install --with-gmp=<CLONE_DIR>/install --with-mpfr=<CLONE_DIR>/install
make -j$(nproc)
make check
make install

You can wrap the output install folder into a rez package by creating a package.py file with the following content:

python
name = "mpc"
version = "<your_version_here>"

def commands():
    env.LD_LIBRARY_PATH.prepend("{root}/install/lib")

Get GCC source ​

git clone git://gcc.gnu.org/git/gcc.git

you can list all available version with:

git tag -l

then

git checkout <version>

rez env ​

bash
rez env mpc mpfr gmp

Build ​

bash
./configure --prefix=<CLONE_DIR>/build --disable-multilib --with-gmp=<GMP+SOURCE_DIR>/install --with-mpfr=<MPFR_SOURCE_DIR>/install --with-mpc=<MPC_SOURCE_DIR>/install
make -j$(nproc)
make check
make install

Exploration build using rez packages build system ​

GMP/MPC/MPFR ​

Example with mpc rez package:

py
def commands():
    if building:
        env.MPC_ROOT = "{root}"

    if system.platform == "windows":
        env.PATH.append("{root}/bin")
        env.PATH.append("{root}/lib")
    else:
        env.LD_LIBRARY_PATH.prepend("{root}/lib")

then gcc/11.2.0/pacakge.py

py
version = "11.2.0"

build_requires = [
    "gmp",
    "mpc",
    "mpfr",
]

build_system = "make"

def env(var: str):
    import platform

    if platform.system == 'windows':
        return f"$env:{var}"
    
    return f"${var}"

@early()
def build_command():
    clone_cmd = ' && '.join([
        "git clone git://gcc.gnu.org/git/gcc.git",
        "cd gcc",
        f"git checkout releases/gcc-{this.version}",
    ])

    configure_cmd = ' && '.join([
        f"./configure --prefix={env('REZ_BUILD_INSTALL_PATH')} --disable-multilib --with-gmp={env('GMP_ROOT')} --with-mpfr={env('MPFR_ROOT')} --with-mpc={env('MPC_ROOT')}"
    ])

    build_cmd = ' && '.join([
        "make -j $(nproc)",
        "make check",
        "make install"
    ])

    return f"{clone_cmd} && {configure_cmd} && {build_cmd}"`
