GCC

2006年10月12日 (四) 08:51的版本

Linux 中最重要的软件开发工具是GCC。GCC（GNU C Compiler）是GNU推出的功能强大、性能优越的多平台编译器，是GNU的代表作品之一。GCC是可以在多种硬体平台上编译出可执行程序的超级编译器，其执行效率与一般的编译器相比平均效率要高20%~30%。

安装 GCC

在 Redhat 下通过 RPM包安装 GCC

install gcc rpm

获得 RPM包 http://fr2.rpmfind.net/linux/rpm2html/search.php?query=GCC&submit=Search+...

rpm -Uvh gcc-3.2.3-34.i386.rpm glibc-devel-2.3.2-95.20.i386.rpm libgcc-3.2.3-34.i386.rpm cpp-3.2.3-34.i386.rpm glibc-headers-2.3.2-95.20.i386.rpm glibc-kernheaders-2.4-8.34.i386.rpm

gcc --version

http://www.linuxfromscratch.org/lfs/view/stable/chapter03/packages.html

All Packages

install gcc 3.4.3

http://gcc.gnu.org/install/

The GCC documentation recommends building GCC outside of the source directory in a dedicated build directory:

tar -xvf *.tar

tar -zxvf *.tar.gz

tar -xjvf gcc-3.4.3.tar.bz2

cd gcc-3.4.3

mkdir -v ../gcc-build

cd ../gcc-build

../gcc-3.4.3/configure --prefix=/tools \

   --libexecdir=/tools/lib --with-local-prefix=/tools \

   --disable-nls --enable-shared --enable-languages=c

or

../gcc-3.4.3/configure --prefix=/usr/local --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-languages=c --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --host=i386-redhat-linux

make bootstrap // make long time

make install

ln -vs gcc /tools/bin/cc

[root@RHELAS3 gcc-build]# /tools/bin/cc --version

Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/specs

gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-53)

libstdc++ install

Porting libstdc++-v3

http://gcc.gnu.org/onlinedocs/porting/

[huihoo@RHELAS3 libstdc++-v3]$ ./configure

configure: error: cannot find install-sh or install.sh in ./../..

./configure --prefix=/usr/local --mandir=/usr/share/man --infodir=/usr/share/info --enable-sjlj-exceptions --enable-version-specific-runtime-libs --enable-cstdio --enable-clocale --enable-libstdcxx-allocator --enable-threads --enable-threads=posix --enable-libstdcxx-debug --enable-c99 --enable-long-long --enable-fully-dynamic-string --enable-concept-checks --enable-libstdcxx-pch --disable-hosted-libstdcxx

RHEL3

/usr/lib/gcc/i386-redhat-linux/3.4.3/libstdc++.so

/usr/lib/gcc/i386-redhat-linux/3.4.3/libstdc++.a

/usr/lib/libstdc++.so.6

/usr/lib/libstdc++.so.6.0.3

在linux 下 make hello.c

mkdir hello

cd hello

建立三个文件

hello.c

configure.in // autoscan创建configure.scan,然后改名为configure.in,这里省略了这个步骤

Makefile.am

hello.c

1. include <stdio.h>

int main(int argc,char *argv[])

{

       printf("hello world\n");
       return 0;

}

在configure.in里加入

AC_INIT(hello.c)

AM_INIT_AUTOMAKE(hello,0.1)

AC_PROG_CC

AC_OUTPUT(Makefile)

在Makefile.am里加入

UTOMAKE_OPTIONS=foreign

bin_PROGRAMS=hello

hello_SOURCES=hello.c

and touch new files: NEWS, README,AUTHORS, ChangeLog

然后执行

$ aclocal

$ autoconf

$ automake --add-missing

$ ./configure

$ make

$ ./hello

It's OK :)

$ make clean

1. make install // 将hello安装到 /usr/local/bin

/usr/local/bin/hello

$ make dist

create package file: hello-0.1.tar.gz

$ make distcheck // 生成发布软件包并对其进行测试检查，以确定发布包的正确性。

提示: hello-0.1.tar.gz is ready for distribution
