c语言的curl 编程
[[email protected] exercise]# gcc -Wall -o curltest curltest.c
/tmp/ccosVANi.o: In function `main‘:
curltest.c:(.text+0x2a): undefined reference to `curl_easy_init‘
curltest.c:(.text+0x53): undefined reference to `curl_easy_setopt‘
curltest.c:(.text+0x5c): undefined reference to `curl_easy_perform‘
curltest.c:(.text+0x68): undefined reference to `curl_easy_cleanup‘
collect2: ld returned 1 exit status
原因：编译器找不到curl库文件
解决办法：确定安装库后， gcc -Wall -o curltest curltest.c -l curl
