編譯的是同一個.C檔案，鏈接的庫都是存在的，只是使用mipsel-openwrt-linux-gcc-4.8的是可以編譯出來執行檔案的，使用新版的mipsel-openwrt-linux-gcc-7.4.0永遠卡在鏈接報錯，且此交叉編譯工具直接從openwrt中編譯出來的，目前測驗了openssl，sqlite3，pthread都是可以正常運行的，只是編譯鏈接curl存在問題，請問如何解決？
目前試過：
1、從openwrt原始碼包里復制動態庫檔案到編譯的檔案夾，修改makefile 鏈接選項到本地----不行！
2、復制mipsel-openwrt-linux-gcc-4.8編譯的庫檔案到編譯檔案夾，修改makefile 鏈接選項到本地----不行！
3、從官網下載openssl和curl原始碼到本地，交叉編譯生成動態庫，其中使用mipsel-openwrt-linux-gcc-7.4.0編譯openssl是可以成功生成，編譯curl------不行！同樣是鏈接報錯！
報錯如下：
報錯的鏈接是直接鏈接openwrt原始碼包路徑的：
使用mipsel-openwrt-linux-gcc-7.4.0 編譯MD5加密鏈接libssl.so是可以通過的：

從錯誤資訊來看，嵌入平臺上 curl 用的不是openssl, 而是 mbedtls，試試安裝 mbedtlsuj5u.com熱心網友回復：
我試過將鏈接路徑增加libmbedtls的動態庫路徑和頭檔案路徑，并且去掉了程式里面的加密段--沒有用uj5u.com熱心網友回復：
編譯curl的時候把mbedtls禁用？轉載請註明出處，本文鏈接：https://www.uj5u.com/caozuo/76161.html
