问题
I'm trying to compile a cpp file which uses static boost libraries. I'm using the visual studio 2008 command prompt as I have not set up a VS project file.
The command I'm using is (run from the folder containing my source code):
cl /EHsc /I "C:\Program Files\boost\boost_1_53_0" Client.cpp
The error is:
LINK: fatal error LNK1104: cannot open file 'libboost_system-vc90-mt-s-1_53.lib'
However, the file 'libboost_system-vc90-mt-s-1_53.lib' can be found in "C:\Program Files\boost\boost_1_53_0\stage\lib" so my understanding is that I've installed boost properly and I'm just failing to link to it?
I've tried including it directly using
cl /EHsc /I"C:\Program Files\boost\boost_1_53_0" /I "C:\Program Files\boost\boost_1_53_0\stage\lib\" Client.cpp
which gives the same error.
I've also tried linking to it directly using /link as follows:
cl /EHsc /I"C:\Program Files\boost\boost_1_53_0" /link "C:\Program Files\boost\boost_1_53_0\stage\lib\libboost_system-vc90-mt-s-1_53.lib" Client.cpp
Which returns a different error:
cl : Command line error D8003 : missing source filename
I seem to be calling the compiler flags wrong? But I can't see where/how.
There is a similar question here,but the solution involves issues with how visual studio/ the project file is set up. Since I don't have a project file, is there an easy solution for the above that I can't see or would I need to set up a project?
Thanks for any help in advance!
回答1:
The linker needs to be told where the library file is located. You were very close with the last command line, but the file name needs to precede the /link option. This should work:
cl /EHsc /I"C:\Program Files\boost\boost_1_53_0" Client.cpp /link "C:\Program Files\boost\boost_1_53_0\stage\lib\libboost_system-vc90-mt-s-1_53.lib"
Also, when linking to multiple libraries in the same directory, it is more concise to use the LIBPATH option to tell the linker where to look for .lib files.
cl /EHsc /I"C:\Program Files\boost\boost_1_53_0" Client.cpp /link "libboost_system-vc90-mt-s-1_53.lib" /LIBPATH:"C:\Program Files\boost\boost_1_53_0\stage\lib\"
