undefined reference to `sm3_digest'

but this error occurs after building the project
When *after" building the project. It does not pop up all on its own! Do you mean during linking? At runtime? Looks like you are not linking with right libraries/versions for whatever
sm3_dogestis orgmssl, or whatever your own code calls, nothing to do with Qt. -
@JonB Sorry, my expression was wrong. It is an error that occurs when building the project. I am using gmssl, which is an external lib library. I have linked it in the .pro file, and after clicking it, I can jump to the original .h file normally, and when using the structure No error was reported, but this error occurred when calling the function.
-
@JonB This is my code.
/Calculate data summary value/
std::vector<uint8_t> UpgradeProtocol::sm3Hash(const std::vector<uint8_t>& data) {
uint8_t hash[SM3_DIGEST_SIZE];
sm3_digest(data.data(), data.size(), hash);
return std::vector<uint8_t>(hash, hash + SM3_DIGEST_SIZE);
}
The following error occurred.

@hhhl01
Your.profile shows you have set theINCLUDEPATH, that will have allowed whatever.hyou include to declaresm3_digest()correctly so that you do not get a compile-time error.Your
LIBSline will have allowed the linker to findGMSSL/lib/libgmssl.ato link against. But it seems it did not find a definition ofsm3_digest()there. Either that symbol is not publicly defined there, or you need another library perhaps as well, or it did not find that file. I'm not sure whether in the latter case (library not found) you would have received an error message from the linker about the-lgmsslargument.Check your documentation, check whether the library file exists in the right place, check that the library you have is indeed a 32-bit build (won't work if it's 64-bit). You can always test the compiling/linking outside of Qt to verify it has nothing to do with Qt.
-
@JonB Thank you for your reply. I checked and found that GmSSL is built on standard 64-bit systems, but at the same time, it also supports 32-bit systems. Will this have any impact? At the same time, this library uses the C language standard. Will it have any impact if I call it directly in the cpp file?Looking forward to your reply, thank you!

Hi,
For which architecture are you building ?
You can't mix and match 64 and 32 bit libraries when building. -
-
@mvuori extern "C" {
#include <gmssl/sm2.h> //Public and private key encryption and decryption
#include <gmssl/sm3.h> //Text hash value
#include <gmssl/sm4.h> //Symmetric key encryption and decryption
}
I've changed it to this format, but it still doesn't work. -
@hhhl01 said in undefined reference to `sm3_digest':
Why does the library have to be 32-bit?
It gets a bit complicated! Your actual Windows is doubtless 64-bit. That can run either 64- or 32-bit applications. Programs or libraries are compiled as either 64- or 32-bit. You cannot mix any 64- and 32-bit stuff within any one application, that and everything it links with must all be one or the other.
Your pasted error message shows that you are building your Qt application as 32-bit (
...MinGW_32bit-Debug...). Somewhere you elected to do that. That means it will only link successfully against libraries also built 32-bit. If yourgmsslhas actually been built as 64-bit it's not going to work.found that GmSSL is built on standard 64-bit systems, but at the same time, it also supports 32-bit systems
I'm not sure exactly what that means. Let's put it aside for now.
Start by looking inside your
GMSSL\libfolder. You are looking for a file namedlibgmssl.a. Do you find that? If so, exactly where? If perchance you do not find that but instead a.libfile namedgmssl.libthat would indicate it has been compiled by MSVC and you won't be able to use MInGW. Otherwise if you do have alibgmssl.awe need to know whether it is 32- or 64-bit. If the latter you would have to change to compiling your own Qt program for 64-bit in order to link with it. -
@JonB Thanks for your reply, I seem to understand what you mean. I just checked that there is only a .lib file named gmssl.lib under GMSSL\lib, which is the library linked to my .pro file. The libgmssl.a file was not found, so the solution is to compile the GMSSL library into 32-bit using mingw? I'm not sure if this is a good approach.

@hhhl01 said in undefined reference to `sm3_digest':
that there is only a .lib file named gmssl.lib
The libgmssl.a file was not found
so the solution is to compile the GMSSL library into 32-bit using mingw?
gmssl.libmeans that was compiled with MSVC. You cannot use that to link against anything of yours compiled with MinGW, regardless of bit-ness. You have 2 choices:-
If
gmssl.libwas supplied to you from whatever the "GMSSL" package is, and you want to use it, you will have to change over to using MSVC instead of MinGW for all your application code you write. You will still have to discover whether the.libfile is 32- or 64-bit and compile your stuff with MSVC correspondingly. -
If you compile the GMSSL sources yourself you can recompile with MinGW (again, correct 32- or 64-bit for whatever you intend to compile your Qt stuff as), producing a
libgmssl.athis time, and you will be able to link against that for your stuff compiled with MinGW. You may find that the GMSSL sources can only be compiled with MSVC, not written to allow MinGW: if so you will have to abandon MinGW and do it and your stuff all with MSVC instead.
The instructions for GMSSL really should document all this.
NOTE:
I don't use Windows or MSVC/MinGW. The above is pretty close to correct. The one thing I am not 100% certain about: if, and only if, GMSSL is C only and no C++ it might be that you can link against a generated.libfile. I say this because I think some Windows system libraries are C-only, are compiled with MSVC and have a.libextension yet have to be acceptable to MinGW. If that is your route you would have to await someone who knows about this specific area.P.S.
In http://gmssl.org/docs/install.html my limited knowledge of Chinese ;-) indicates it is intended to be built with MSVC/Visual Studio. What evidence do you have it will ever compile/work with MinGW? -
-
@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.
-
@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? -
