相关选项的含义可以通过"man gcc"看出(有问题,找男人),譬如man gcc后检索inline-functions: ? 从O0到O1,O2,O3,是一个开启的优化选项逐步加大的过程: ?...O0编译会报如下错,说f()函数没有定义: $ gcc -O0 cc.c cc.c:1:13: warning: ‘f’ used but never defined [enabled by default...: error: ld returned 1 exit status 但是用O2编译,则没有问题: $ gcc -O2 cc.c 原因在于,O2编译,它意识到a==1,所以if(a>2),它不会成立,所以...to `f' collect2: error: ld returned 1 exit status 所以,通过这个例子,大家可以看出来为什么同样的代码,用O2就可以过,用O0就过不了。...`f' collect2: error: ld returned 1 exit status 5.

其实,C源代码的确是有点难度,但是掌握了LD_LIBRARY_PATH概念就还好了,下面我就简单介绍一下: LD_LIBRARY_PATH是Linux环境变量名,该环境变量主要用于指定查找共享库(动态链接库.../lib/:$LD_LIBRARY_PATH ¨G1G /usr/bin/ld: cannot find -llzma collect2: error: ld returned 1 exit status...make[1]: *** [lancet] Error 1 make[1]: Leaving directory `/home/jianmingzeng/biosoft/lancet/lancet/src...lib/:$LIBRARY_PATH 为什么修改LD_LIBRARY_PATH呢 因为运行时动态库的搜索路径的先后顺序是: 1.编译目标代码时指定的动态库搜索路径; 2.环境变量LD_LIBRARY_PATH...指定的动态库搜索路径; 3.配置文件/etc/ld.so.conf中指定的动态库搜索路径; 4.默认的动态库搜索路径/lib和/usr/lib; 这个顺序是compile gcc时写在程序内的,通常软件源代码自带的动态库不会太多

如果编译遇到如下错误: tmp/cceMNWaA.o:(.eh_frame+0x12): undefined reference to `__gxx_personality_v0' collect2:...ld returned 1 exit status 则可能是因为使用gcc编译cpp文件,两个办法: 1.将文件名改成.c文件 2.加上链接选项-lstdc++
