NOTE: The procedures described in the following sections must be completed before this step:
This section describes the process of building binutils, gcc, and
newlib manually using configure and make directly.
The following example illustrates the invocation of
configure and make
to build and install binutils-2.9.5.0.24 for the
sparc-rtems target:
mkdir b-binutils cd b-binutils ../binutils-2.9.5.0.24/configure --target=sparc-rtems \ --prefix=/opt/rtems make all make info make install
After binutils-2.9.5.0.24 is built and installed the
build directory b-binutils may be removed.
For more information on the invocation of configure, please
refer to the documentation for binutils-2.9.5.0.24 or
invoke the binutils-2.9.5.0.24 configure command with the
--help option.
Before building gcc-2.95.2 and newlib-1.8.2, binutils-2.9.5.0.24 must be installed and the directory containing those executables must be in your PATH.
The C Library is built as a subordinate component of gcc-2.95.2. Because of this, the newlib-1.8.2 directory source must be available inside the gcc-2.95.2 source tree. This is normally accomplished using a symbolic link as shown in this example:
cd gcc-2.95.2 ln -s ../newlib-1.8.2/newlib .
The following example illustrates the invocation of
configure and make
to build and install binutils-2.9.5.0.24 for the
sparc-rtems target:
mkdir b-gcc cd b-gcc ../gcc-2.95.2/configure --target=sparc-rtems \ --with-gnu-as --with-gnu-ld --with-newlib --verbose \ --enable-threads --prefix=/opt/rtems make all make info make install
After gcc-2.95.2 is built and installed the
build directory b-gcc may be removed.
For more information on the invocation of configure, please
refer to the documentation for gcc-2.95.2 or
invoke the gcc-2.95.2 configure command with the
--help option.
