TMS VCL UI Pack 10.1.5.1 to 10.1.6.1 Link Errors

Sarraf_Elias · January 26, 2020, 7:42am

I have a C++Builder project that compiles and links with no errors in Tokyo 10.2.3 with VCL UI Pack 10.1.5.1.

After upgrading to VCL UI Pack 10.1.6.1 I get 16 unresolved external reference linker errors all of 'libssh2_xxxxxxx' errors. Here are the first 3 from the errors list:

[ilink32 Error] Error: Unresolved external 'libssh2_sftp_stat_ex' referenced from C:\RADTOOLS\TMSSOFTWARE\TMS VCL UI PACK\DELPHI102TOKYO\WIN32\RELEASE\TMSVCLUIPACKPKGDXE11.LIB|WUpdate
[ilink32 Error] Error: Unresolved external 'libssh2_sftp_open_ex' referenced from C:\RADTOOLS\TMSSOFTWARE\TMS VCL UI PACK\DELPHI102TOKYO\WIN32\RELEASE\TMSVCLUIPACKPKGDXE11.LIB|WUpdate

I reverted back to 10.1.5.1 and the project compiles with no errors again.

thank you for your help,

Elias

I seem to have the same error. I just upgraded to C++Builder Pro 10.3.3 and have the newest TMS VCL UI Pack 10.1.6.1. I am getting linker errors for the two components WUpdate and WebCopy. I am using the 32bit Clang compiler. The errors are below. I saw in the docs there was a recent update to the WebCopy component. Any suggestions?

We added SFTP support to TWebCopy and TWebUpdate and apparently for C++Builder specifically this introduces this issue.
Immediately solution: obtain from the libssh2 open source project libssh2.lib and add in your main CPP file:

#pragma link "libssh2.lib"

We're working to make this all automatic for the next TMS VCL UI Pack update.

Mikula_Patrick · January 29, 2020, 12:55am

I have downloaded the open source project from here libssh2(dot)org. This does not include a .lib file. I am not sure if I downloaded the wrong project or if I need to compile the project and create the libssh2.lib file myself.

I was able to download a file named libssh2.lib at the link below and added #pragma link "libssh2.lib" to my main .cpp list of #pragma links but the error is the same, so this must be the wrong file.

github(dot)com/adamdruppe/arsd/blob/master/libssh2.lib

Can you show a download link to the correct .lib?

Mikula_Patrick · January 29, 2020, 5:17am

I have reinstalled the last version of TMS Component pack. I will try the new UI Pack again after the next upgrade.

brunofierens · January 29, 2020, 1:35pm

We released v10.1.6.2 that includes the .lib (Win32) and .a (Win64) file now.

Mikula_Patrick · June 27, 2024, 4:33pm

The problem with TWebCopy and libssh2.lib described in this thread from 2020 has returned with the C++Builder Win64-Modern platform. The folder AppData\Local\TMS Setup\Products\tms.vcl.uipack contains the files libssh2.lib(32bit) and libssh2.a(64bit). The platform Win64-Modern seems to be looking a 64bit file with the extension .lib not .a. Below is the error I am getting. How would you recommend we handle this?

[ld.lld Error] ld.lld: error: C:\Users\Nitro\AppData\Local\TMS Setup\Products\tms.vcl.uipack\libssh2.lib: unknown file type

Thanks

brunofierens · June 27, 2024, 7:42pm

Make sure there is a 64bit libssh2.lib file in the Win64 modern library path.

Mikula_Patrick · June 27, 2024, 11:49pm

I don't think I have a x64bit libssh2.lib file. On my computer I have a folder named "tms.vcl.uipack" which I have attached a picture. I have a file named libssh2.lib which I believe is 32bit, then libssh2.a which is 64bit. These point to the file libssh2.dll.

Notice in the picture there is a file named "libssh2_x64.dll" but there is no corresponding .lib file named libssh2_x64.lib. I believe TWebCopy needs to use the file libssh2_x64.dll when using the 64bit-modern platform but it seems to be targeting libssh2.lib and is hitting the 32bit .lib file causing the error "unknown file type".

[ld.lld Error] ld.lld: error: C:\Users\Nitro\AppData\Local\TMS Setup\Products\tms.vcl.uipack\libssh2.lib: unknown file type

brunofierens · June 28, 2024, 6:26am

As a test, can you try to rename libshh2.a to libshh2.lib?

Mikula_Patrick · June 29, 2024, 2:21am

The pictures below shows that I have renamed the 32bit file libssh2.lib as "libssh2_32bit.lib" and then renamed the 64 bit file libssh2.a as "libssh2.lib". This test gives one error: [ld.lld Error] ld.lld: error: unknown file type: libssh2

brunofierens · June 30, 2024, 4:26pm

Seems x64 expects a different kind of .lib file.
Unfortunately, I haven't found such version from libssh distributions so far.

Mikula_Patrick · July 1, 2024, 7:04am

Ok. Thanks for spending time looking into this.

Mikula_Patrick · July 5, 2024, 1:56pm

I found a solution to this problem. I used the instructions posted by Embarcadero at the link below to create a new .lib file for libssh2.dll. The new .lib file allows the Win64x compiler to use the TMS component WebCopy.

Create Win64x .LIB file

Thanks for sharing this very useful information!
