In addition to Armeen's very important questions, I have additional ones:
What is "too long"... Can you please quantify this extremely loose and subjective term?
Can you describe in general terms how the objects are organized/grouped into the 70 libraries? Is there a schema or plan in place, does a developer place any object in any library he/she chooses, or something in between?
Has your app been developed with a framework of any kind? If so, which?
Do you use a dedicated "build" machine? Physical or virtual? What CPU and # of cores? How much physical memory? Does it use solid state drive(s) (SSD's)?
How critical is it that you lessen the build time? Are you willing to try non-free 3rd-party products to see if it would provide significant improvement?
How often are you required to perform a full build?
Are you willing to try reorganizing the objects or have you already tried to reorganize the objects differently to improve build and/or execution performance?
The source is on the local drive. The anti-virus software opens the source folder.
It is set as a scan exception.
And my computer specifications are by no means bad.
Because of compilation speed, I used the solution from the topwiz site.
I tried compiling individual PBLs because it was faster.
There is no problem when running it from the source, but when running it from an executable file,
There was an error, so I regenerated the related pbl and compiled it.
There will be no errors if you upload it.
