Here is what the compile log reads when I attempt to compile my Opposing Force map:
** Executing...
** Command: Change Directory
** Parameters: D:\Alt\Program Files (x86)\Steam\steamapps\common\Half-Life
** Executing...
** Command: Copy File
** Parameters: "D:\Alt\Program Files (x86)\Steam\steamapps\common\Half-Life SDK\maps\op4_warp.map" "\op4_warp.map"
From what I can tell, this indicates that none of the build programs are performing any tasks, and Hammer is instead re-locating/copying a pre-existing .map file to a different location. I thoroughly checked the options tab to ensure that hammer has been pointed to all the right build programs, and it should be running them. This has been a persistent problem for which almost no tutorials or documentation can be found online. Does anyone know what's going on or have a guess on how to troubleshoot this? Any and all help is greatly appreciated
