Re: [Mingw-cross-env-list] 回复： VS can't use the static library compiled with MinGW under Debian

[Zach Thibeau]

oh mingw can support it well enough, but building a static library in mingw and then trying to use it within visual studio won't work since it uses different compiling procedures, now say if you have a dll and you managed to get an definitions export on it (.def) you could use

lib /machine:x86 (or x68 if it's from a 64bit dll) /def:testdll.def 

and you can use that generated lib that way but static libraries compiled from mingw just in general does not play nice with other compilers.

Hi, Volker,

Thanks for your reply. First, I must say sorry for posting questions on wrong mail list. I will move this question to your recommended mail list, i.e. MinGW-User. Second, it seems that MinGW doesn't support DLL related staff very well. And my final goal is to build a static library for my customer. Anyway, thanks.

Cheers,

Hu Jingfei

Static linking is compiler specific. You can't expect this
to work across different compilers (MinGW vs. VS). Usually,
you can't even expect this to work with multiple versions
of the same compiler, although you could have some luck here.

However, why do you want to do that?

If you want to distribute binaries for your library, you
should probably use dynamic linking (DLL files) instead of
static linking. If your final goal is an application (not a
library), then simply build everything with the same compiler.

Also note that this mailing list is mostly about cross
compiling. Basic questions about static vs. dynamic linking
have better chances for good answers on the MinGW-Users
mailing list.


Greets,
