AIX 安装GCC

AIX 安装GCC1. Installing the RedHat Package Manager (RPM)在安装GCC软件之前，必须安装RPM - the RedHat Package Manager。

你需要用installp安装RPM包, 下载此包的地址为：ftp:///aix/freeSoftware/aixtoolbox/INSTALLP/ppc/rpm.rte安装rpm 包，必须以root 用户操作，命令如下:# installp -qacXgd rpm.rte rpm.rteing the RedHat Package Manager (RPM)使用RPM的完整信息详见. 基本的安装操作参数:-i: install-e: erase-q: query--help: helprpm程序在/opt/freeware/bin/中#cd /opt/freeware/bin/# ./rpmRPM version 3.0.5Copyright & 1998 - Red Hat SoftwareThis may be freely redistributed under the terms of the GNU GPL3.下载GCC软件包到/servers/aix/products/aixos/linux/download.html上下载gcc以root用户执行如下步骤：# /opt/freeware/bin/rpm -i gcc-4.0.0-1.aix5.3.ppc.rpm## find / -name "gcc" -print/opt/freeware/bin/gcc/opt/freeware/lib/gcc/opt/freeware/libexec/gcc/usr/bin/gcc你可以在shell的提示符号下键入gcc -v,萤幕上就会显示出你目前正在使用的GCC的版本.在我的系统上,执行gcc -v的结果是:# gcc -vUsing built-in specs.Target: powerpc-ibm-aix5.3.0.0Configured with: ../configure --with-as=/usr/bin/as --with-ld=/usr/bin/ld --disable-nls --enable-languages=c,c++ --prefix=/opt/freeware --enable-threads --enable-version-specific-runtime-libs --host=powerpc-ibm-aix5.3.0.0Thread model: aixgcc version 4.0.04.测试方法只要执行gcc时,附加-v这个参数(switch),就能找出你所用的这版gcc,自动帮你定义了什麽符号(symbols).例如,我的机器看起来会像这样:# echo 'main(){printf("hello world\n");}' | gcc -E -v -Using built-in specs.Target: powerpc-ibm-aix5.3.0.0Configured with: ../configure --with-as=/usr/bin/as --with-ld=/usr/bin/ld --disable-nls --enable-languages=c,c++ --prefix=/opt/freeware --enable-threads --enable-version-specific-runtime-libs --host=powerpc-ibm-aix5.3.0.0Thread model: aixgcc version 4.0.0/opt/freeware/libexec/gcc/powerpc-ibm-aix5.3.0.0/4.0.0/cc1 -E -quiet -v -ignoring nonexistent directory "/usr/local/include"ignoring nonexistent directory "/opt/freeware/include"ignoring nonexistent directory "/opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.0.0/../../../../powerpc-ibm-aix5.3.0.0/include"#include "..." search starts here:#include <...> search starts here:/opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.0.0/include/usr/includeEnd of search list.# 1 "<stdin>"# 1 "<built-in>"# 1 "<command line>"# 1 "<stdin>"main(){printf("hello world");}通过编译程序文件的方式来测试编译器是否正常工作.C编译器的测试,执行如下命令：#cd /db2db/event#vi cvevm.ccvevm.c内容如下：#define KEYNUMBER 23#include <stdio.h>#include <string.h>int SearchText(char *str);int main(int argc, char ** argv){FILE *fp_in,*fp_out;char buffer[32767];char *ptr ="abc" ;int i;int sequence=0;char *oper="sadf";char *value="skdf";char rec[KEYNUMBER][32767];if(argc != 3){printf("Usage:cvevm input output\n"); exit(1);}fp_in = fopen(argv[1],"r");fp_out = fopen(argv[2],"w");if((fp_in == NULL) || (fp_out == NULL)) {printf("open file failure\n");exit(1);}while(!feof(fp_in)){fgets(buffer,sizeof(buffer),fp_in);if(feof(fp_in)) break;ptr = strstr(buffer,"Statement Event"); if(ptr){sequence++;while(1){fgets(buffer,sizeof(buffer),fp_in);if(feof(fp_in)) break;if (!strncmp(buffer," sqlstate",11)){break;}oper = strtok(buffer,":");if(oper){i = SearchText(oper);if(i > 0){value = strtok(NULL,":");if(value){value[strlen(value)-1] = 0;strcpy(rec[i],value);}}}}fprintf(fp_out,"%d",sequence);for (i=0;i<KEYNUMBER;i++) {if(i == 10){rec[i][11] = 0;}if(i == 12){rec[i][12] = 0;}if(i == 13){rec[i][10] = 0;}if (i == 9){fputc('"',fp_out);fprintf(fp_out,"%s",rec[i]);fputc('"',fp_out);fputc(',',fp_out);}else{fprintf(fp_out,"%s,",rec[i]);}}fprintf(fp_out,"\n");}}fclose(fp_in);fclose(fp_out);}int SearchText(char *str){char *opers[KEYNUMBER] = {" Appl Handle"," Type "," Operation"," Section "," Creator "," Package "," Cursor "," Cursor was blocking"," Text "," Exec Time"," Number of Agents created"," User CPU"," System CPU"," Fetch Count"," Sorts"," Total sort time"," Sort overflows"," Rows read"," Rows written"," Internal rows deleted"," Internal rows updated"," Internal rows inserted"," sqlcode"};int i;for(i=0;i<KEYNUMBER;i++){if (strncmp(str,opers[i],strlen(str)) == 0) {return (i+1);}}return 0;}编译cvevm.c# gcc cvevm.c -o cvevm没有错误出来,证明OK!。
