推 acake:兩個thread有需要用mutex同步嗎? 05/01 20:10
推 RouterHsieh:沒有產生core dump嗎？ 05/01 22:04
→ RouterHsieh:話說這問題跟本板沒啥關係..轉去LinuxDev比較恰當吧 05/01 22:05

→ bitlife:你自少要知道結束原因,程式自己正常exit,一般signal 或 05/02 11:53
→ bitlife:SIGSEGV 05/02 11:53
→ BIAO:我的程式是設定...無窮迴圈 二個thread都是.. 所以才納悶XD 05/02 13:00
→ bitlife:所以我說要先找出原因,你可以先用交談式shell把程式丟背景 05/02 13:32
→ bitlife:shell不要登出,等程式結束,shell會顯示程式怎麼結束的 05/02 13:33
→ BIAO:謝謝b大.. 沒用過shell!不過現在明白處理方式了，感謝您~~~ 05/02 13:50
→ bitlife:你用linux但沒用過shell?這...? 那你怎麼跑程式的? 05/02 14:50
回b大的話...
我都是用vim編輯C code，
用gcc編譯後，直接用sudo ./執行程式..
偶爾加個&來背景執行.. XD

→ bitlife:你sudo那行命令應該就是在交談式shell下執行的 05/02 15:10
→ bitlife:執行 echo $SHELL 就知道你目前是用什麼shell 05/02 15:11
→ BIAO:(!!!) 原來是這個樣子..謝謝b大 :D 05/02 15:16
→ BIAO:目前已物色到一本不錯的書..準備入手!! 05/02 15:20
→ BIAO:我是用bash~~~ 05/02 16:16
目前已經完全懂b大的意思..
我的確是在interactive mode執行程式，
不過就算執行沒加上&，程序自行結束時也沒有產生程序如何結束..
我是使用Ubuntu Linux，目前在尋找產生Core dump的方法XD
C語言程序是無窮迴圈，二個thread都是..

→ kdjf:gcc -g (debug), 加上gdb試試看吧 05/02 21:51
→ lantw44:$SHELL 是登入的時候設定的，如果自己開其他 shell 05/02 22:46
→ lantw44:不會跟著變 05/02 22:46
→ bitlife:樓上,我是看原po連shell是什麼都不知道,所以才叫他看目前 05/02 23:21
→ bitlife:是什麼shell XD 05/02 23:21
→ bitlife:不過你這補充說明對原po還是有用就是了 05/02 23:23
感謝大家的回覆，參照k大做法，
採用gcc -o -g -DDEBUG modbus+MySQL+Control26 modbus+MySQL+Control26.c
-I/usr/include/mysql -L/usr/lib/mysql -lmysqlclient -lpthread，
得到了許多資訊..
