Glib – 来自glib的未定义引用？
我的S程序有问题。 我需要用这个命令编译它：
gcc -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -lglib-2.0 \ -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -Wall -Wextra -g -std=c99 -lm *.c \ -o generator1_1 我有很多这样的错误消息：

我使用Ubuntu 12.04。 有谁有想法吗？
在“对象”文件之后包含由-l指定的库（或者在编译源并同时链接所有源文件时包含源文件）。
你有：
gcc -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include \ -lglib-2.0 \ -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -Wall -Wextra -g -std=c99 \ -lm *.c -o generator1_1
你需要：
gcc -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include \ -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -Wall -Wextra -g -std=c99 \ *.c -lglib-2.0 -lm -o generator1_1
可能有一些系统可以在链接命令行中的任意位置指定库，但“目标文件后的库”始终适用于我遇到的所有系统。
