undefined reference error错误的原因是:没有指定对应的库(.o/.a/.so) 使用了库中定义的实体,但没有指定库(-lXXX)或者没有指定库路径(-LYYY),会导致该错误,连接库参数的顺序不对 在默认情况下,对于-l 使用库的要求是越是基础的库越要写在后面,无论是静态还动态 gcc/ld 版本不匹配 gcc...
编译时出现undefined reference to `libiconv_open’的解决办法 这是什么问题呢?其实是缺少libiconv库的原因。 1.libiconv包的下载路径 包的下载页面http://www.gnu.org/software/libiconv/ The latest release ishttps://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.15.tar.gz wget http://ftp.gnu.org/pub/gnu/...
This happened twice while compiling commit 375de49. I was able to work around the errors in a terminal window with the following commands: when make stops the first time: pushd lib/tgdb/tgdb-base # solved by dropping all -I and -L option...
test.a(test.o): In function `test': test.c:(.text+0x13): undefined reference to `func' collect2: ld returned 1 exit status 因此,我们需要注意,在链接命令中给出所依赖的库时,需要注意库之间的依赖顺序,依赖其他库的库一定要放到被依赖库的前面,这样才能真正避免undefined reference...
错误就是链接的时候找不到函数呀。。先检查一下makefile里面做链接的时候有没有-lsqlite3,或者检查下库的名字是不是改了 有的话,再看看实际用到的libsqlite3.a里有没有这个函数,nm看下sqlite3_open是不是T 有的话,看看sqlite3_open的参数是不是错了;没有的话,就自己重新编一个。。。
: undefined reference to `sqlite3_close' collect2: ld returned 1 exit status 那么,恭喜你中招了。错误根本不在SQLITE也不在你的程序,而在GCC。Gcc的编译参数是有顺序的。正确的编译命令是: gcc -o hello -L /usr/local/lib -I/usr/local/include -static hello.c -lsqlite3 ...
