1、invalid conversion from ‘const char*’ to ‘char*’
解決：
pn = strchr(p, PATH_SP);
改為
pn = (char *)strchr(p, PATH_SP);
2、 ‘PACKAGE_STRING’ was not declared in this scope
‘PACKAGE_BUGREPORT’ was not declared in this scope
解決：
fprintf(stderr,"%s Copyright: YuHong(992126018601033)",PACKAGE_STRING);
fprintf(stderr,"bug report: %s\n\n",PACKAGE_BUGREPORT);
替換為：
fprintf(stderr,"CTorrent devel Copyright: YuHong(992126018601033)");
fprintf(stderr,"bug report: [email protected]\n\n");
3、fatal error: openssl/sha.h: 沒有那個文件或目錄
缺少 openssl dev包，解決：安裝libssl-dev
sudo apt-get install libssl-dev
4、undefined reference to `SHA1_Init'
undefined reference to `SHA1_Update'
undefined reference to `SHA1_Final'
解決1：
1.確認你裝了openssl
2.g++ 後加上參數 -lssl
解決2：
或者/usr/lib/libssl.so加入程序library庫下
Eclipse CDT下設置g++參數的方法
Project->Properties->C/C++ Build->Setting->GCC C++ Linker->Miscellaneous->Linker Flag 處加上 -lssl
