Trouble getting DevExpress to reinstall with new Indy

[JohnnyMarauder]

I am stuck and tried following several messages on DevExpress support, but the nut is I am still getting the error:

E2202 Required package 'IndyCore' not found

I downloaded the repo to C:\Repos\Indy on my system, I did the manual uninstall of the old Indy as I am running XE, opened the .groupproj and was able to get it installed per the instruction (but had to add the paths to the \Lib folder so it would find the idGlobal file) Anyway, it is in there.

I am not sure what DevExpress is doing that it cannot find the new Install, but I suspect it is hard-coded to look for something I have renamed because I cannot have the old and new Indy at the same time. I renamed the C:\Program Files (x86)\Embarcadero\RAD Studio\8.0\source\Indy to Indy.old.

Do I need to create an Indy folder there and copy some files from the C:\Users\Public\Documents\RAD Studio\8.0\Dcp folder where the new files got compiled too?

I wish I knew more on how the stuff under the hood works.

Sounds like DevExpress depends on the version of Indy that ships pre-installed in Embarcadero IDEs.

The package files that are in Indy's repo contain package version numbers in their file names (ie, for XE, the packages have 150 appended to their names). However, Embaradero strips off those version numbers from the pre-installed package names (and rightly so - Indy should be doing that anyway, that is scheduled for Indy 11).

If you want to use a newer version of Indy with DevExpress, you are likely going to have to either:

• update DevExpress to refer to Indy's version-specific package names.
• alter Indy's package files to drop the version numbers.

Thank you for helping, Remy. Are there instructions on what I have to change in the Indy150 files to accomplish the latter option?

[JohnnyMarauder]

While waiting for instructions, I did the following: I went into each of the Core, Protocols and Systems folders, and copied the 150. files to their non numbered counterparts. I then edited the various dpk, dproj files and removed "150" wherever I found it. I also did the same thing in the Indy\Lib folder to the groupproj and groupproj.local files. I then opened this newly modified Indy.groupproj file, and compiled and installed the files per the wiki. This all went without a hitch, and Delphi XE opened as normal.

However, when trying to install DevExpress , I still get the E2202 required package IndyCore not found. I read that DevExpress uses dcc32 to compile the packages, so maybe I am missing something in the dcc32.cfg file pointing to the libraries? This is where I am not sure to what my next step is.

Also here is the cmd file I used to create the Indy files to compile and install:

With these changes made and modifying the dcc32.cfg to include the paths to the new Indy as follows:

-aWinTypes=Windows;WinProcs=Windows;DbiProcs=BDE;DbiTypes=BDE;DbiErrs=BDE -u"C:\Program Files (x86)\Embarcadero\RAD Studio\8.0\lib\win32\release";"C:\Program Files (x86)\Embarcadero\RAD Studio\8.0\lib\Obj";C:\Repos\Indy\Lib\Core;C:\Repos\Indy\Lib\Protocols;C:\Repos\Indy\Lib\System

I started the install of DevExpress again and now I get slightly further but with a different error:

Cannot compile dxHttpIndyRequestRS15.dpk Compiler: C:\Program Files (x86)\Embarcadero\RAD Studio\8.0\Bin\dcc32.exe Embarcadero Delphi for Win32 compiler version 22.0 Copyright (c) 1983,2010 Embarcadero Technologies, Inc.

Not sure what to do on this one. I've posted this to the DevExpress support page as well.

I might be going about this all wrong. What do I need to change in the new Indy so I can compile and install it side-by-side with the original Indy that comes with XE?

[rlebeau]

I went into each of the Core, Protocols and Systems folders, and copied the 150. files to their non numbered counterparts. I then edited the various dpk, dproj files and removed "150" wherever I found it. I also did the same thing in the Indy\Lib folder to the groupproj and groupproj.local files. I then opened this newly modified Indy.groupproj file, and compiled and installed the files per the wiki. This all went without a hitch, and Delphi XE opened as normal.

In addition to stripping off the version numbers from the file names, you will likely also need to update the projects to use the LIBSUFFIX directive so the final compiled BPL files still DO have version numbers on them.

I started the install of DevExpress again and now I get slightly further but with a different error:

C:\Forbin\DevExpress VCL\Library\RS15\dxHttpIndyRequestRS15.dpk(52)
Error: E2466 Never-build package '.dxHttpIndyRequestRS15' requires always-build package 'IndyProtocols'

Error: E2466 Never-build package '.dxHttpIndyRequestRS15' requires always-build package 'IndyCore'

Not sure what to do on this one.

See https://docwiki.embarcadero.com/RADStudio/en/E2220_Never-build_package_%27%25s%27_requires_always-build_package_%27%25s%27_(Delphi)

Indy's packages are set to IMPLICITBUILD ON by default:

https://docwiki.embarcadero.com/RADStudio/en/Implicit_Build_(Delphi)

I suspect that Embarcadero probably switches this to OFF in the pre-installed Indy packages.

What do I need to change in the new Indy so I can compile and install it side-by-side with the original Indy that comes with XE?

The two versions can't be installed side-by-side. Only one version can be active in the IDE at a time.

[JohnnyMarauder]

Thanks for the help. I did find that DevExpress did install, but just failed on the 4 or 5 components that actually used Indy. Otherwise it installed and I was able to open my project that referenced both Indy (the new one) and the DevExpress controls.

But, it turns out the program still fails to receive the response packet from a Shark270 Meter (modbus protocol). So I am not sure if this is an Indy problem or a delphi-modbus library(that also uses Indy) problem. The code does work with other modbus meters. I may have to purchase a retail modbus TCP library unless you have any thoughts.

[rlebeau]

I couldn't really comment on that without seeing the actual modbus protocol data and the code that is trying to read it.
