%general-entities; ]> $LastChangedBy$ $Date$ GCC-&gcc-version; The GCC package contains GNU compilers. This is useful for compiling programs written in C, C++, Fortran, Java, Objective C and Ada. Download (HTTP): Download (FTP): Download MD5 sum: &gcc-md5sum; Download size: &gcc-size; Estimated disk space required: &gcc-buildsize; Estimated build time: &gcc-time; Required Patch: Required Patch: Test Suite: If you plan to compile Ada, you will need to install GNAT temporarily to satisfy the circular dependency when you recompile GCC to include Ada. Download (HTTP): Download (FTP): Download size: &gnat-size; Estimated disk space required: &gnat-buildsize; Estimated build time: &gnat-time; Install GNAT by running the following commands: ./doconfig The above script will ask you how and where you would like to install GNAT. To avoid conflicts with the system gcc, the package will be installed in a separate directory, that can later be removed from the system. In response to the questions asked by the doconfig script, enter 3 in response to the first question and /opt/gnat in response to the second question. To finish the install, run the following command as the root user: ./doinstall The GNAT compiler can be invoked by executing the gcc binary installed by the above script. Prepare to compile GCC by placing the GNAT gcc at the beginning of the PATH variable by using the following commands: PATH_HOLD=$PATH && export PATH=/opt/gnat/bin:$PATH Install GCC by running the following commands: The installation process may overwrite your existing GCC compiler and libraries. It is highly recommended that you have the Tcl, Expect and DejaGnu packages installed, as well as unpacking the GCC testsuite tarball before beginning the build. Do not continue with the make install command until you're confident the build was successful. You can compare your test results with those found at . There's also an i686 platform test result produced by an LFS-6.0 system at . You may also want to refer to the information found in the GCC-Pass 2 section of Chapter 5 in the LFS book. Some of the Java programs installed by the GCC package conflict (have the same names) with programs from the package. If you're installing the Java language from the GCC package but you wish to use the programs from the JDK as the defaults, ensure $JAVA_HOME/bin is listed before /usr/bin in your PATH variable. patch -Np1 -i ../gcc-&gcc-version;-no_fixincludes-1.patch && patch -Np1 -i ../gcc-&gcc-version;-linkonce-1.patch && sed -i 's/install_to_$(INSTALL_DEST) //' libiberty/Makefile.in && mkdir ../gcc-build && cd ../gcc-build && ../gcc-&gcc-version;/configure --prefix=/usr --libexecdir=/usr/lib \ --enable-shared --enable-languages=c,c++,objc,f77,ada,java \ --enable-threads=posix --enable-__cxa_atexit --enable-clocale=gnu && make bootstrap && make -C gcc gnatlib-shared && make -C gcc gnattools && make -k check && ../gcc-3.4.1/contrib/test_summary Now, as the root user: make install && ln -v -sf ../usr/bin/cpp /lib && ln -v -sf gcc /usr/bin/cc && ln -v -sf g77 /usr/bin/f77 && chown -v -R root:root /usr/lib/gcc/i686-pc-linux-gnu/&gcc-version;/include You may remove the GNAT installation and restore your old PATH: rm -rf /opt/gnat && export PATH=$PATH_HOLD sed -i 's/install_to_$(INSTALL_DEST) //' libiberty/Makefile.in: This command suppresses the installation of libiberty.a as the version provided by Binutils is used instead. mkdir ../gcc-build; cd ../gcc-build: The GCC documentation recommends building the package in a dedicated build directory. --enable-languages=c,c++,objc,f77,ada,java: This command identifies which languages to build. You may modify this command to remove undesired languages. --enable-shared --enable-threads=posix --enable-__cxa_atexit: These commands are required to build the C++ libraries to published standards. --enable-clocale=gnu: This command is a failsafe for incomplete locale data. make -C gcc gnatlib-shared: This command builds the Ada shared and static libraries. Skip this step if you have not enabled Ada as one of the languages. make -C gcc gnattools: This command builds the Ada development tools and binaries. Skip this step if you have not enabled Ada as one of the languages. make -k check: This command runs the test suite without stopping should any errors be encountered. ../gcc-3.4.1/contrib/test_summary: This command will produce a summary of the test suite results. You can append | grep -A7 Summ to the command to produce an even more condensed version of the summary. You may also wish to redirect the output to a file for review and comparison later on. ln -sf ../usr/bin/cpp /lib: This command creates a link to the C PreProcessor as some packages expect it to be installed in the /lib directory. ln -sf gcc /usr/bin/cc; ln -sf g77 /usr/bin/f77: These links are created as some packages refer to the C and Fortran compilers using an alternate name. chown -R root:root /usr/lib/gcc/i686-pc-linux-gnu/&gcc-version;/include: If the package is built by a user other than root, the ownership of the installed include directory (and its contents) will be incorrect. This command changes the ownership to root:root.
