c++ - G++ 警告 : built for unsupported file format which is not the architecture being linked

Question

每当我尝试编译我的项目时(使用命令行g++ *.hpp *.cpp 2> log.txt)，我得到的就是:

log.txt:

ld: warning: in configfile.hpp, file was built for unsupported file format which is not the architecture being linked (x86_64)
ld: warning: in erase.hpp, file was built for unsupported file format which is not the architecture being linked (x86_64)
ld: warning: in filehandler.hpp, file was built for unsupported file format which is not the architecture being linked (x86_64)
ld: warning: in insert.hpp, file was built for unsupported file format which is not the architecture being linked (x86_64)
ld: warning: in operation.hpp, file was built for unsupported file format which is not the architecture being linked (x86_64)

知道为什么会这样吗？我在 OSX 10.6 下(使用最新的开发者工具)

您正在编译您不应该做的头文件 (.hpp)。只编译源文件(.cpp)

与其编译所有 .cpp 文件，不如一次编译一个，然后适本地链接它们。

g++ -c x.cpp
g++ -c y.cpp
g++ -c z.cpp

g++ -o tst x.o y.o z.o

请注意，只有一个 .cpp 文件可以具有 main() 函数 - 否则操作系统将不知道入口点在哪里。
