Question

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。有没有人有任何想法？

在＆＃39;对象＆＃39;之后加入由-l指定的库。文件（或编译源文件时的源文件，并一次链接所有文件）。

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，但是在目标文件之后的库中可以指定库。我一直致力于我曾经遇到过的所有系统。

Glib - 来自glib的任何未定义的引用？
