看来这些是内部链接错误？我如何找到这些错误的来源？
答案 0 :(得分：0)
您需要编译所有文件并将它们链接在一起。它要么缺少cpp文件或库
答案 1 :(得分：0)
这可能是问题所在。您需要使用-L来指定库文件的位置。 -I用于指定包含文件的位置。
g++ "-IC:\\Users\\Jesse\\Documents\\Work\\Research\\FiberTracking\\Software\\mrtrix\\source\\mrtrix-0.2.11\\lib" "-IC:\\Users\\Jesse\\Programs\\gtk+\\lib" "-IC:\\Users\\Jesse\\Programs\\gtk+\\bin" "-IC:\\Users\\Jesse\\Programs\\gtk+\\include\\glib-2.0" "-IC:\\Users\\Jesse\\Programs\\gtk+\\lib\\glib-2.0\\include" "-IC:\\gtkmm64\\include\\glibmm-2.4\\glibmm" "-IC:\\gtkmm64\\include\\glibmm-2.4" "-IC:\\gtkmm64\\lib\\glibmm-2.4\\include" "-IC:\\gtkmm64\\include\\sigc++-2.0" "-IC:\\gtkmm64\\lib\\sigc++-2.0\\include" "-IC:\\Program Files (x86)\\GnuWin32\\include" "-IC:\\Program Files (x86)\\GnuWin32\\include\\gsl" -O0 -g3 -Wall -c -fmessage-length=0 -o "src\\mrconvert.o" "..\\src\\mrconvert.cpp"
我认为其中一些应改为-L。例如
"-IC:\\Users\\Jesse\...lib"
应该是
-L"C:\\Users\\Jesse\...lib"
应该进入联系线。即连接所有内容的第二行。
