undefined reference to `sm3_digest'

[hhhl01]

@JonB Sorry it took so long to get back to you.I still haven't been able to solve this problem. I replaced the mingw 32-bit compiler with msvc 64-bit, but it still can't link to the library correctly.

The Chinese meaning here is:
upgrade_protocol.obj : error LNK2019: unresolved external symbol sm3_digest referenced in function "private: class std::vector<unsigned char, class std::allocator<unsigned char>> __cdecl UpgradeProtocol::sm3Hash(class std::vector<unsigned char, class std::allocator<unsigned char>> const &)" (?sm3Hash@UpgradeProtocol@@AEAA?AV?$vector@EV?$allocator@E@std@@@std@@AEBV23@@Z)

I don't know if it's the same problem as the one I encountered before. I'm thinking if it's a library problem.Looking forward to your reply, thank you.

[hhhl01]

@JonB I also need to explain that my current development environment is the windows platform.

And the external library I linked to is 64-bit.

I think there is no problem with my build environment, so is it possible that the Windows platform is causing this error?

[jsulm]

@hhhl01 Please post you current pro file and also the output of the linker during the build. And please post text, not pictures.

[JonB]

@hhhl01
Maybe @jsulm can help you.

But I have to say: this doesn't seem to be anything to do with Qt, nobody knows what GMSSL is all about, there are basically no hits on the web for sm3_digest. This is really down to you to find out what is required to build it correctly from its documentation.

@jsulm Hello.Thanks Hello.Thanks for your reply. This is my .pro file.

@JonB Thank you, I will try to find out the cause of the problem and will get back to you if there are any results.This library is indeed relatively rare, but I cannot modify the specifications in the project.

@hhhl01 said in undefined reference to &#x60;sm3_digest':

else:unix:!macx: LIBS += -L$$PWD/../../GmSSL/gmssl.lib

On Unix/Linux this is wrong.
Please check https://doc.qt.io/qt-6/qmake-variable-reference.html#libs

$$PWD/../../GmSSL/debug/gmssl.lib - is this path valid?
Are the missing functions part of the gmssl library?

[hhhl01]

@jsulm This path is valid, I'm developing on windows platform, when I change it to the format below it doesn't work.

else:unix:!macx: LIBS += -L$$PWD/../../GmSSL/lib/ -lgmssl

I didn't say you have to change it for Windows.

Again: "Are the missing functions part of the gmssl library?"
Was this library built using same compiler?

Yes, it is part of the library. And the library is constructed using the same compiler.
