I got problems when using the libs installed by vcpkg

[huangrunqian]

My system is Windows10, and I installed openssl & zlib by
vcpkg.exe install openssl:x64-windows openssl-windows:x64-windows zlib:x64-windows
Then I built other projects linking to these libs, and I got following errors:

 error LNK2019: Unresolved external symbol deflateEnd    
 error LNK2019: Unresolved external symbol deflateInit_    
 error LNK2019: Unresolved external symbol deflateInit2_    
 error LNK2019: Unresolved external symbol EVP_DigestSignUpdate    
 error LNK2019: Unresolved external symbol SSL_get1_peer_certificate

However, if I copy libcrypto.lib and libssl.lib installed by anaconda and cover the libs installed by vcpkg, the last two errors could be solved. Does that mean the libs I installed didn't packed these when building? What should I do to solve these problems?

@huangrunqian Thanks for posting issue, sorry, I didn't reproduce your problem locally.

PS E:\test\vcpkg> 

For openssl, libcrypto.lib name seems to have changed, make sure you use the latest vcpkg and try again.

[FrankXie05]

Maybe you can specify these two libs in Visual Studio. Related issue #12001

[huangrunqian]

I just tried git pull and vcpkg.exe update, and then vcpkg.exe install openssl:x64-windows-static openssl-windows:x64-windows-static. Then I use dumpbin on Windows to find the symbol EVP_DigestSignUpdate and SSL_get1_peer_certificate in the libs, but I still couldn't find them, while I could find them in the libs with the same name installed by anaconda.

[FrankXie05]

Please delete the cache before retry, this is the result of my query notation. Obviously, openssl has the required symbols in the exported libcrypto.lib and libssl.lib.

[huangrunqian]

I tried to delete the whole vcpkg folder and restart everything:
git clone --single-branch -b master https://github.com/microsoft/vcpkg.git
cd vcpkg
git checkout a82c62d
git pull
bootstrap-vcpkg.bat
vcpkg.exe update
vcpkg.exe install openssl:x64-windows openssl-windows:x64-windows rapidjson:x64-windows re2:x64-windows boost-interprocess:x64-windows boost- stacktrace:x64-windows zlib:x64-windows pthread:x64-windows b64:x64-windows
Then I got the following error:

[FrankXie05]

Is the error still the same? If not, please provide the error log:
D:\github\vcpkg\buildtrees\openssl\build-x64-windows-rel-1-err.log

[huangrunqian]

I used CMD for administrator to run the commands, and installed openssl successfully. However, now I got
error LNK2019: Unresolved external symbol SSL_get_peer_certificate
Still used dumpbin to check libssl.lib, there is no SSL_get_peer_certificate there.

[huangrunqian]

However, there is SSL_get1_peer_certificate and EVP_DigestSignUpdate now.

[huangrunqian]

Maybe it's not the problem of the openssl lib... I cleaned my project and built from the start, everything seemed fine and I don't know why. So I'm just closing this issue.
