Problem:

I get the following messages when trying to compile or install my own package, 3rd party package, or 3rd party framework:

• "The following changes are necessary to make this package compatible with other installed packages. Choose OK to apply these changes and rebuild the package: Add EurekaLogCore. EurekaLogCore contains implicit unit(s) Web.Win.IsapiHTTP".
• "Cannot load package 'my-package.' It contains unit 'Web.Win.IsapiHTTP', which is also contained in package 'EurekaLogCore'."

Reason:

1. Same unit may not appear in two or more loaded packages;
2. Web.Win.IsapiHTTP unit is not included in any default RTL/VCL package, which means this unit became part of any package that references this unit.

E.g. Web.Win.IsapiHTTP becomes part of EurekaLogCore package, your own package / 3rd party package / 3rd party framework.

Solution:

You need to move Web.Win.IsapiHTTP unit into a new package, which will be shared by all other packages that need Web.Win.IsapiHTTP unit:

Step 1: prepare shared package:

1. Create new run-time package;
2. Add Web.Win.IsapiHTTP unit to this package ("contains" section);
3. Add rtl, vcl, inet packages to "requires" section;
4. Build modified package.

Step 2: redirect other packages to use new shared package:

1. Open EurekaLogCore package (available in EurekaLog Enterprise);
2. Add package name from previous step to "requires" section;
3. Rebuild the package;
4. Use "Manage EurekaLog in IDEs" tool to reinstall EurekaLog.

Step 3+: repeat "Step 2" actions for your own packages, 3rd party packages, 3rd party frameworks.
